I'm partnered with an early-stage, post-revenue AI startup is building an end-to-end operating system to help businesses detect and resolve complex B2B issues before they become costly or disruptive. The product is already being used by large enterprises across multiple industries, and demand is growing fast - hence this hire!

Backed by a top-tier European venture fund, the company is tackling a huge, under-served market and is at the point where strong engineering leadership will materially shape the product and platform.

The Role

  • Build and own end-to-end features using TypeScript, React, Next.js and Node.js.
  • Design and evolve a cloud-native AWS stack (Lambda, DynamoDB, AppSync, S3, CloudFront).
  • Take ownership of architectural decisions while remaining highly hands-on.
  • Maintain high quality through strong testing practices (Jest/Vitest, Cypress) and regular refactoring.
  • Work closely with product, design and AI, with a high degree of autonomy and trust.

What We’re Looking For

  • Strong TypeScript experience across frontend and backend. (Node.js)
  • Deep hands-on experience with React & Next.js (SSR, SSG, routing, edge where relevant).
  • Proven ability to design secure, scalable and reliable systems, ideally for B2B products.
  • Comfortable operating in ambiguity and making sound technical decisions.
  • Someone who takes real ownership and helps raise the bar for the team.

Nice to Have

  • AWS serverless experience.
  • GraphQL (Apollo, tRPC or similar).
  • Exposure to enterprise software, compliance or governance requirements.
