Senior Full Stack Software Engineer
£100,000–£110,000 + benefits
UK-based | Hybrid – London 2 days per week
Certus Recruitment is working with an ambitious UK fintech building a regulated stablecoin and digital payments platform.
We are looking for a Senior Software Engineer to join at an early stage and help build the application, financial infrastructure and settlement technology behind the platform.
This is a highly hands-on role, working closely with the Head of Engineering across back-end services, core systems and customer-facing applications.
The role
You will work across:
- Back-end services and transaction workflows
- Financial transaction and settlement systems
- Compliance and authorisation logic
- Database design and transactional integrity
- APIs, event-driven architecture and shared schemas
- Customer-facing and internal applications
- Blockchain and on-chain settlement integration
You’ll be turning architecture and design documentation into robust, tested and production-ready software.
What we're looking for
- 5+ years' professional software engineering experience
- Strong back-end engineering experience
- Experience taking systems from prototype through to production
- Strong TypeScript and PostgreSQL/SQL skills
- Experience with strongly typed languages
- Rust experience is highly desirable, or a strong systems background with the ability to learn quickly
- Experience with event-driven and transactional systems
- Strong written communication and a design-led approach
- Collaborative, hands-on and comfortable taking ownership
Experience in fintech, payments, banking, custody or financial infrastructure would be advantageous.
Blockchain or stablecoin experience isn't essential, but you'll need an interest in developing your knowledge of on-chain systems.
The opportunity
Join at a genuinely formative stage and help build the technology behind a new regulated digital currency platform.
You’ll have significant ownership across the stack, working on systems that will ultimately move from sandbox to regulated production.
