Senior Developer - Capital Markets Technology (C++ / C# · Azure · Summit)

Do you want to work on technology that sits at the heart of capital markets? In Nykredit’s Markets Technology team, you will help evolve a business-critical trading and risk platform with Summit as its core component, while integrating it with a modern cloud-based landscape.

We’re looking for a Senior Developer (~5+ years’ experience) who takes ownership, solves complex problems independently, and contributes to raising the technical bar across the team.

The Nykredit Group is owned by an association of our customers, Forenet Kredit. This means that when we succeed, our customers benefit from that success, and that we take a special responsibility for the society we are part of. As our new Senior Developer, you'll experience this unique approach firsthand.

What you’ll do:

• Design and build high-performance components in C++ and C# within the Summit platform.
• Own integrations between Summit and surrounding systems, including Azure-based data platforms.
• Translate requirements from trading, risk, and operations into robust technical solutions.
• Take end-to-end ownership of components, making design decisions and collaborating across systems when needed.
• Support and mentor other developers through sparring, reviews, and knowledge sharing.

Are you the one we're looking for?

Must-have:

• 5+ years of experience in C++ and/or C# in complex, business-critical systems.
• Strong understanding of system design, performance, and integration patterns.
• Experience working with trading or risk platforms (e.g., Summit, Calypso, or similar).
• Experience with or strong interest in Azure-based integrations, data services, and cloud-native development patterns.
• Ability to work independently, take ownership, and communicate clearly with both engineers and business stakeholders. 

Nice-to-have:

• Experience with real-time or data-intensive systems.
• Experience with event-driven architecture, APIs, messaging, or data pipelines in a cloud environment.

Why join?
As part of this role, you will help shape and modernize a core capital markets platform that supports business-critical trading, risk management, and operational processes. You will work with complex financial systems where quality, performance, and engineering decisions have a direct and visible impact. With significant technical ownership, you will play an active role in influencing the platform’s future development alongside the surrounding IT landscape and cloud-based data services. You will collaborate closely with experienced business specialists, architects, and developers in a team that values practical solutions, knowledge sharing, and strong technical judgment. At the same time, you will have the opportunity to build deep expertise in capital markets technology and pursue a clear path toward architecture and technical leadership.

Your new team
Markets Technology is responsible for developing and operating Nykredit’s sell-side capital markets platform. You will join a team of around 30 skilled and dedicated colleagues working across the full capital markets value chain - from trading and risk to operations and platform development. The team works closely with business specialists, architects, infrastructure partners, and other technology teams to ensure stable, scalable, and future-ready solutions. We combine deep domain knowledge with strong engineering practices and a pragmatic approach to solving complex problems in a regulated financial environment.

The position can be based in either Copenhagen or Warsaw.
