Senior Software Engineer

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!

Maintain high quality through strong testing practices (Jest/Vitest, Cypress) and regular refactoring.

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
