Senior Software Engineer - Node.js, Typescript & AWS Financial Services

Location: London Hybrid - 1 day onsite ; Salary: £75,000 - £ 105,000

About the role: We're looking for a Senior Software Engineer to join our engineering team and build reliable, scalable technology supporting regulated investment and custody services.

You'll work in a highly autonomous, cross-functional squad with genuine ownership across the full software lifecycle - from architecture and development through to production support and incident management.

Required Skills:

  • Strong commercial Node.js and TypeScript experience.
  • Solid AWS and Serverless experience.
  • Experience building distributed, resilient APIs.
  • Experience with MongoDB or another document database.
  • A strong understanding of testing, observability and performance.
  • Experience working in financial services, fintech, startups or another regulated environment.
  • Experience mentoring engineers and taking ownership of production services.

If you're a Senior engineer who enjoys ownership, modern AWS architecture and building technology that powers real financial products, we'd love to hear from you.
