About Our Client

Our client is a Series A developer-tools startup, backed by leading SaaS and infrastructure investors and building a product that engineers genuinely love. Following clear product-market fit, adoption is accelerating and the team is scaling deliberately — hiring senior people, keeping the organisation flat, and protecting a high-trust, low-process culture. This is an environment where individual engineers have outsized impact on the roadmap and on the company. The company is kept confidential at this stage; full details, including the client name, are shared with shortlisted candidates.

Job Description

Our client is hiring a Full-Stack Engineer to ship customer-facing features across the entire stack for a developer-tools product that engineers genuinely love. You'll join a small, senior team where ideas move from conversation to production quickly, and where a strong product instinct is valued as much as technical craft. This is an opportunity to have visible, weekly impact on a product used by a fast-growing community of developers.

  • Build and ship features end-to-end across a React/TypeScript front end and a Node/Go back end
  • Own features from initial idea and design through to production, iteration and measurement
  • Contribute to product decisions — bringing a point of view on what to build and why
  • Design pragmatic APIs and data models that support fast iteration
  • Care for performance, accessibility and developer experience across the product
  • Collaborate closely with design and other engineers in a tight feedback loop
  • Write tests and help maintain a healthy, fast CI/CD pipeline
  • Help shape engineering practices and standards in an early-stage environment
  • Debug and resolve issues across the stack, in development and production

The Successful Applicant

We're looking for a versatile, product-minded engineer who is happy owning features across the stack and thrives in a fast-moving startup.

  • 3+ years of full-stack engineering experience
  • Strong proficiency in TypeScript and React on the front end
  • Solid experience with a backend language (Node, Go, Python or similar)
  • A genuine product mindset and a bias to ship and iterate
  • Comfortable working in an early-stage, ambiguous, fast-changing environment
  • Good understanding of APIs, data modelling and testing
  • Strong collaboration and communication skills
  • Interest in or experience with developer tools is a plus
