We're looking for a Senior Software Engineer specialised in Golang to join a fast‑growing, regulated fintech business that are building modern digital products to support both consumers and businesses. With a mobile-first product, the company brings strong emphasis on compliance, risk management, and operational resilience, while still moving quickly through agile, iterative delivery.
You will be a core member of a collaborative engineering team, working across their retail app backend, business account services, and internal admin systems - writing clean, performant, production-grade Go that powers real financial products used by real customers. You'll contribute to architectural decisions, champion engineering best practices, and help shape how the team builds and scales as the business grows.
Key Responsibilities:
- Design, build, and maintain scalable, resilient backend services and APIs in Go
- Collaborate closely with product, engineering, and operations to deliver high-quality, well-tested software
- Contribute to architectural decisions and help define engineering standards as the team grows
- Identify and address performance bottlenecks, reliability concerns, and technical debt
- Support a culture of code quality through thorough code reviews and documentation
- Work within a regulated environment, ensuring solutions meet compliance and security requirements
Key Requirements:
- Strong commercial backend engineering experience with hands-on Go exposure - Go is the primary language, though we'll consider engineers whose background is in Python provided they have practical Go experience
- Solid understanding of microservices architecture and REST and/or gRPC API design
- Comfortable working with AWS and Docker-based environments
- Experience with relational and/or NoSQL databases and event-driven systems
- Collaborative, low-ego, and comfortable operating with autonomy in a small team
- Experience or exposure to regulated domains (e.g. fintech, payments, banking) is a nice to have, not a dealbreaker
What's on Offer:
- 90,000-110,000 base salary
- Equity options
- A flat structure with direct access to leadership and real influence over how the engineering team evolves
This is an opportunity for a Senior Golang Engineer who takes pride in their craft, thrives in a fast-moving environment, and wants to play a meaningful role in building financial products where reliability, security, and performance are non-negotiable.
