Software Engineer - FinTech product

This is a role for an engineer who wants real influence. As a Senior Software Engineer, you'll work across teams to solve our hardest problems, shape key architecture decisions, mentor the next generation of engineers, and lead how we adopt AI-assisted and agentic development across the whole engineering organisation. Experience

• 5+ years (or equivalent) of software development experience.
• 2+ years with React (or a similar frontend framework) and 2+ years with NodeJS.
• Deep, practical knowledge of TypeScript, microservice architecture and AWS (we run Fargate, moving to Lambda, API Gateway and SQS).
• A track record of mentoring, raising engineering standards and pragmatic technical decision-making.
• Hands-on fluency with AI-assisted development tools and clear-eyed judgement about their strengths and limits. Skills Our engineers work in self-organised Scrum teams building new features and products on a modern stack: TypeScript, NodeJS and React, microservices on AWS (Fargate today, moving to Lambda, API Gateway and SQS), with TDD and full CI/CD. AI-assisted development (GitHub Copilot, Claude Code, Cursor) is a growing part of how we build - we invest in using it well, and every engineer owns and reviews what ships.
