A Cardiff-based fintech working in private markets is looking for a senior Go developer to join a small, experienced engineering team. The platform handles large volumes of financial data. This is a backend-only role focused on a core calculation engine. No frontend work.
What you'll be doing:
- Building and optimising financial calculation services in Go
- Processing and reconciling high volumes of capital, positions and holdings data
- Designing for scalability, low latency and long-term reliability
- Contributing to system design and infrastructure decisions alongside a senior team
- Integrating backend services with a PHP Laravel presentation layer
What they're looking for:
- Strong commercial Go experience — this is the core requirement
- Experience working in fintech, financial services or similarly data-intensive environments
- Solid understanding of API design, performance tuning and system architecture
- Comfortable owning critical components, not just delivering to a spec
Useful but not essential:
- Microservices and distributed systems
- AWS or GCP
Why apply?
- Hybrid setup: 3 days in Cardiff, 2 from home
- Forward-thinking team exploring AI-assisted coding
- Modern tech stack with room to innovate and grow
