At its foundation, SimCorp is guided by our values - caring, customer success-driven, collaborative, curious, and courageous. Our people-centered organization focuses on skills development, relationship building, and client success. We take pride in cultivating an environment where all team members can grow, feel heard, valued, and empowered.

ABOUT OTC CORE

In the OTC Core Product Area, we work on functionality supporting over-the-counter financial instruments in SimCorp’s main product, SimCorp Dimension. Our work brings together financial contract modelling, functional programming, and C#/.NET development.

Most of our development work centres on financial contract models written in an internally developed domain-specific language embedded in OCaml. These models bring together business logic, database mapping, and user-interface layout in one place. Alongside implementing the models, we evolve the language itself and the supporting C#/.NET framework.

You do not need to arrive as an expert in OTC instruments or OCaml. What matters is curiosity about the problems, strong programming foundations, and a willingness to learn.

WHAT YOU WILL WORK ON

As part of a cross-functional team working across locations, you will contribute from the first discussion of a feature through design, implementation, testing, and support.

You will:

  • Implement financial contract models in our OCaml-based domain-specific language, defining their business logic, database mapping, and user-interface layout.
  • Evolve the OCaml-based language and supporting C#/.NET framework, balancing new capabilities with improvements to existing code.
  • Use AI-assisted development tools - including Claude, GitHub Copilot, and our internally developed cloud agent - to explore solutions, develop code, and improve tests, applying your engineering judgment to validate the results.
  • Work with product management and fellow engineers to understand business needs and turn them into maintainable solutions.
  • Build automated tests and use code reviews to improve correctness, clarity, and maintainability.
  • Help make technical decisions, address technical debt, and share your experience with colleagues.

WHAT YOU BRING

We are primarily looking for a senior engineer who can work through complex problems, contribute to design decisions, and collaborate effectively with others.

We value:

  • Strong programming and software design skills, with experience in C#/.NET or functional programming.
  • The ability to understand an existing system and make thoughtful, well-tested changes.
  • Curiosity about functional programming, financial modelling, and the business problems behind the code.
  • A collaborative approach: asking questions, explaining your reasoning, and giving and receiving constructive feedback.
  • Clear communication in English and a willingness to keep learning.

Experience with OCaml or other functional languages (Haskell, Scala, F#, or similar), domain-specific languages, Web APIs, or financial software would be useful - but you do not need to bring all of it. A relevant degree or equivalent practical experience can provide a foundation; we are interested in what you can do and how you approach problems.

BENEFITS

  • Global hybrid work policy - We ask you to work 2 days a week from the office. If you choose you can work remotely the other days. Of course you are welcome at the office if that is your preference.
  • Growth and innovation - Every 6th sprint is reserved for planning and innovation. So, with regular intervals you have a chance to explore and learn new skills or improve something that you believe will be beneficial to you, your team or the application.
  • Self- Direction - High degree of self-organization. Each team and developer have a high degree of freedom to plan, organize and design their work.
  • Inclusive and diverse company culture.
  • Pension and health benefits and bonus.
  • Work-life balance - We truly believe that an equilibrium between professional responsibilities makes us all the best version of our self's, both in private life and as a colleague in the workplace.
  • Empowerment - We believe that all voices are valuable and must be heard. You will involved in shaping our work processes.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
