I’ve been working at InControl since 2023 as a software developer on ERS, our high-performance simulation platform. I looked exactly for a job like this because I love making simulations, solving hard engineering problems, and doing things that haven’t been done before.

A typical day means working on hard problems that push the limits of what computers can handle. We deal with making large simulations run fast in parallel, keeping everything synchronized and efficient. It’s challenging, but that’s what makes it fun.

We’re so far on the edge that we’ve had to report compiler bugs directly to Microsoft. We hit issues most people never run into, and they’ve been fixing them for us.

What makes it fun is the team. Everyone here cares. We get a lot of satisfaction out of making things faster, simpler, and more reliable. We review each other’s code, share ideas, and constantly try to improve what we’ve built.

If you like solving hard problems and want to work on something that actually pushes the edge of what computers can do, InControl is a good place for that.

Gayathri

Engineer

I’m Gayathri Subramanian, a Simulation Engineer at InControl, where I’ve been working since 2023. My work primarily focuses on pedestrian and traffic modelling, with my contributions centered around the modelling, interacting with the clients and delivery phases of various projects.

What I enjoy most about this role is the dynamic nature of the work—no two projects are the same, and there’s always a real-world impact to be seen. From simulating pedestrian flow in stadiums and experience centers like museums to working on unconventional and complex movement scenarios, each project brings new learning opportunities. For instance, my very first project involved complex pedestrian and traffic simulations for a U.S. client, followed by a cable car simulation for a client in Saudi Arabia. Just when you think you’ve mastered something, a new and more challenging project comes along, keeping the learning curve exciting and ongoing.

The team at InControl is highly professional and always willing to support one another, which creates a positive and collaborative work environment. Coming from a research background, I’ve learned how to apply my skills from an industry perspective, thanks to the hands-on experience and mentorship I’ve received here.

One of the aspects I truly appreciate is the flexibility InControl offers. Whether it’s picking up kids from school or planning a vacation, good communication has always made it easy to manage both work and personal commitments. The company places a strong emphasis on work-life balance, which makes daily life far less stressful.

I’m confident that anyone who joins the InControl family will experience the same supportive, flexible, and intellectually stimulating environment that I’ve been fortunate to be part of.

Douwe

Engineer

Hi! My name is Douwe and I’ve been working at InControl since the beginning of 2021 as a simulation engineer in the Crowd Simulation team. I develop simulation models and applications for new stadiums, train stations, museums, urban environments and other crowded places, using our in-house software Pedestrian Dynamics.

We use these models to assess whether the infrastructure design can handle the number of people it is intended for. For example, what will the crowd density be in a redesigned train station, if we use the expected number of passengers and the timetable of 2040? What are the walking times for the most popular transfers, and what delays occur due to crowdedness?

However, it’s not only about regular operations, but also about safety in case of evacuations. For special events like football finals or concerts in stadiums, we simulate the evacuation plan of the stadium and report the evacuation times from people’s seats to the streets. Thanks to the detailed microsimulation, we can identify in which sections of the stadium the evacuation times do not meet safety regulations, and we test improvements to the plan. Believe me, this really is something you want to simulate rather than test in real life.

Since a few months, I’ve also been working for the Public Transport team, where we develop the rail simulation software that our clients use to improve the processes on the railroads in terms of efficiency and safety. Many future innovations are included, like the automated train operations, and the future European safety system ERTMS. After switching teams, I started learning some additional programming skills, since in Public Transport team we do not only use our own 4DScript language, but also C#, SQL and more.

In my job, my background in applied mathematics comes in handy mostly when scripting and programming. But also when new concepts need to be worked out and built in. Furthermore, a good understanding of statistics and simulation is always useful!

We have regular contact with clients, for example when presenting the results of crowd simulation studies and brainstorming how to improve the infrastructure. But also with users of our software when they report bugs or have support questions. Some colleagues of the Public Transport team even work from the clients’ office one day a week, to demonstrate and discuss new functionality.

Besides enjoying the work itself, I think a very important factor is the atmosphere within a company. Since we are a relatively small company, everybody knows each other and all colleagues are very approachable. Every now and then after work, some of us go out for some drinks together or organize a games night at the office. Furthermore, our staff association organizes fun activities.

Deena

Engineer

My name is Deenalakshmi and I work as a Simulation Engineer within the Industry team at InControl. I joined the company in 2022. Since then, I’ve had the opportunity to work on a range of exciting simulation projects that bridge technology and operations.

As a Simulation Engineer, I help design, build, and analyze simulation models to support decision-making in complex logistical and operational environments. This includes modeling systems, identifying inefficiencies, and testing potential improvements in a virtual environment before they’re implemented in the real world.
warehouse implementing SAP Extended Warehouse Management (EWM). We developed an emulation model that replicated tasks like receiving, put-away, picking, and shipping, and connected it to the SAP EWM control logic. By testing the full end‑to‑end process in a virtual environment, we identified configuration tweaks and material‑flow adjustments before commissioning—saving weeks of on‑site testing and minimizing go‑live risk.

I was excited by the opportunity to tackle real‑world challenges head‑on. As a Simulation Engineer at InControl, I get to work across a diverse range of industries—every engagement brings a new operational puzzle to solve.

Whether it’s optimizing warehouse flows or validating control logic for manufacturing lines, I love that the simulation models we build helps in decision making  and directly shapes how organization runs.

The culture in our team is highly collaborative everyone pitches in to troubleshoot challenges. We share learnings openly, run regular “Team days” and have an appreciation to what each can bring to the table.

I work on projects that involve extensive model building and scenario analysis, which keeps every assignment fresh and engaging. Beyond modeling, I also contribute to the development of our simulation software offering insights and enhancements from a simulation‑engineer’s perspective. I’m involved in testing and validating new feature or improvement, ensuring our tools perform reliably under real‑world conditions.

The real‑life impact we deliver is twofold: we identify system shortcomings in advance and propose solutions, and we validate the sustainability of our designs before they go live. For example, I conducted a study to determine how many automated guided vehicles (AGVs) were needed to hit a specific throughput target. By modeling the current performance and simulating scenarios with additional AGVs, we quantified the improvement in throughput. This detailed analysis gave the customer the data they needed for a clear investment and cost‑benefit assessment, ultimately supporting a more confident go‑forward decision

At InControl, during the first few weeks, new hires undergo in‑depth training on our simulation software, paired with structured team‑integration sessions so you quickly become a contributing member. We also benefit from our mentoring program, which matches you with a senior engineer for regular coaching. We also have quarterly career‑path reviews to set goals and identify stretch assignments that align with your growth ambitions.

Since joining InControl as a Simulation Engineer, I’ve become more confident in tackling new challenges and have significantly improved both my technical and communication skills. I also enjoy that I get to pick up and learn new skill sets—whether it’s an advanced modeling technique, data‑processing workflow, better visualization techniques or a new scripting library, that help me keep curious and enjoy my work.

My typical day starts with a brief stand‑up meeting to align with the team on priorities. Followed with dive into model development or testing to prepare for the delivery package to the customer. The day might also include some scenario runs or discussions about the results. Later followed with some team meetings or some development work. I like the fact that I have a variety of work in my plate. No two work week looks the same.

I love the strong sense of community we have here. One highlight is our monthly “Bottles and Cases” events, where we bring in external speakers to share cutting‑edge knowledge in simulation and related fields—followed by relaxed socializing over drinks. We also host half‑yearly company‑wide outings packed with fun team‑building activities and a group dinner. These help in building connections across teams, making InControl both inspiring and enjoyable to be part of.

Marnix

Engineer

Hi! My name is Marnix, and I’ve been working as a simulation engineer at InControl as a member of Team Industry since 2023. Our team designs and uses simulation models in Enterprise Dynamics (our company’s own simulation software!) to support various industrial clients, including distribution centra, factory floors, and my main focus: the baggage handling system of Schiphol Airport.

I primarily work with a detailed simulation model of a baggage handling system which our team has been building and refining over many years. As you might imagine, this system is big, complex, and always changing. As such, the model hast to be continuously improved and updated, which is an important part of my work.  I then use the model in projects to answer specific questions of the client. For example, a recent project revolved around answering the question: “How can we adjust our daily operations to keep the system running  smoothly during an upcoming maintenance period when part of the system will be offline?”. This process involves gathering relevant information, making project-specific model changes, running simulations and discussing our findings with the client. As I’m usually part of two to three projects at a time, most workdays are nicely varied.

What initially made me apply for the role was the concept of simulation itself. Thinking about how to translate a real-world system into a mathematical model is always a nice challenge, and it is interesting to see how the model behavior reacts to changes to the logic or input.

Over my time here, I’ve gained a lot of experience working with large, complex systems. Building a simulation model forces you to consider a wide range of factors, and to evaluate which ones to include in the model. In the model I work on, such factors include the hardware and software of the infrastructure components, the operational procedures, the flight schedule, and much more.

Fortunately, I don’t have to tackle this alone; I work in a team of engineers of different experience levels. Usually, there are 2 or 3 people involved in a project, so there is sufficient opportunity to brainstorm and share ideas. The team has an informal atmosphere, and working together goes smoothly as everyone is approachable and knows what they are talking about.

I usually spend three days a week at the office, and we try to coordinate our schedules so we can plan most of our meetings face-to-face. The other two days I work from home, where I can focus on getting work done without many interruptions. This, and the fact that work is limited to standard office hours, makes for a good work-life balance.

Gerben

Engineer

I have been working at InControl since finishing my Computing Science master in 2017. Since I am interested in working in a smaller company and I love to work in a field where the software relates to tangible concepts, I joined team Rail. I’m still assigned to that team, where I help developing our railway simulation software. I contribute to all aspects of simulation development, this includes project management, specification, conceptual design, technical design, implementation and modelling.

I like how the simulations we provide we give our clients insight in their own (future) operations. One such a case is a project where train drivers and train traffic dispatchers work together in a simulated environment to test future processes. I was great to see how the processes that were defined on paper came alive in a simulation.

The broad range of railway aspects where I get introduced to keeps me challenged. Every new project lets you dive into new parts of the railway world. I like to continuously improve our simulator with every project we deliver.

My colleagues also help to keep work fun, for instance, I love the board game nights we have once in a while.

  • What exactly do you do in your role? Can you give an example of a project you’ve worked on recently?

Help developing our existing railway simulation software where I am contributing to the project management, specification, conceptual design, technical design and implementation. One such a project is coupling a real onboard Automatic Train Operation module to our timetable-simulator.

  • What makes your work at InControl interesting or challenging?

The broad range of railway aspects where I get introduced to. Every new project lets you dive into new parts of the railway world. I like to continuously improve our simulator with every project we take.

  • Why would you recommend working at InControl to others?

It is a great place to get challenged in simulation development while getting to know one or more interesting fields outside development itself.

  • Do you have a fun anecdote or memory you’d like to share?

I really liked the simulation test-sessions we had with traindrivers and train traffic controllers. We developed a simulation where they could experience processes as they will be in the future. Here it was great to hear how, they gained new insight in how their own specifications would affect their work.
