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.

• 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.
