Charlotte Smith

Backend Engineer - High-Traffic Platform 🚀

💰Up to £70,000

🏡Hybrid working - London based

💻Node.js & TypeScript

We're partnered with a fast-growing London-based startup who are looking for a Mid-Level Backend Engineer to help scale a high-traffic platform at pace. This role is ideal for a Node.js developer who wants real ownership, rapid delivery, and the chance to grow quickly in a startup environment.

They've recently onboarded new clients and with huge growth plans for 2026, this is a great opportunity to join a fast growing business!

You'll work across a wide range of backend projects - building new platform features, developing third-party integrations, and creating APIs that power customer-facing applications. As part of a small, collaborative team, you'll make meaningful contributions from day one, own significant areas of the product, and see your work shipped quickly.

What You'll Be Doing

  • Build and maintain backend services and APIs using Node.js
  • Develop new features across internal tools and customer-facing products
  • Design and implement integrations with third-party and partner systems
  • Write clean, well-tested, maintainable code
  • Design database schemas, optimise queries, and ensure data integrity
  • Collaborate closely with frontend engineers and other stakeholders
  • Troubleshoot and resolve production issues with a focus on reliability
  • Contribute ideas to improve systems, architecture, and processes

What We're Looking For

  • 3-5 years of professional backend engineering experience
  • Strong experience with Node.js and TypeScript
  • Proven experience building RESTful APIs and/or GraphQL
  • Solid knowledge of relational databases (PostgreSQL preferred)
  • Experience writing unit and integration tests
  • Comfortable working with Git and collaborative workflows
  • Strong problem-solving and communication skills
  • Ownership mindset - able to take projects from idea to production
  • Comfortable working in a fast-moving, sometimes ambiguous environment

This is a great opportunity to join a growing business and if you'd like to find out more about the role, please reach out to me on charlotte@burnssheehan.co.uk

Burns Sheehan Ltd will consider applications based only on skills and ability and will not discriminate on any grounds.
