• G reminds us to always Grow and win together. We only succeed by supporting each other and challenging ourselves, and our team-mates, to reach for new heights;
• N is here for Nose for value because we are always looking to focus on what matters most to our clients, partners and team.

Sygnum has one of the most diverse teams in the industry. Diversity plays a central role in keeping our work culture open, our teams productive and energised, and our solutions at the forefront of the industry. In the spirit of our SYGN value to “grow and win together”, we fully embrace an equal opportunity mindset in the way we onboard, develop and promote our team members.

As a senior software engineer on the Team, you will:

• Design and build new features, writing and reviewing high-quality, secure code.
• Work directly with backend and our BFF to define contracts and keep the client and server sides aligned.
• Identify technical debt in the codebase and push through the plan to repay it, not just flag it.
• Respond to production incidents promptly, working across teams to restore service and get to the real root cause.
• Collaborate with designers to keep the UI consistent and usable across a growing feature set.
• Work with platform engineers to improve CI/CD and release processes.

Few things that will help on the job

• Expertise in React and Typescript.
• Working experience with CI/CD pipelines.
• Working experience defining frontend architecture, particularly for a client-facing product at scale.
• Working with BFFs.
• Comfort working against backend APIs and feature-flagging systems (we use Flagsmith).

The Web Portal Team owns the web application our clients use every day to manage their digital assets: trading, custody, staking, and account management, all in one place. It's the front door to the bank for thousands of clients, so what we ship here is what they see and feel first.

As a senior software engineer, you'll help shape one of Sygnum's most visible products.
