The Opportunity
We’re working with a remote-first AI startup that’s solving one of the most overlooked problems in enterprise: how companies manage supplier disputes. They’re building a modern, cloud-native platform powered by AI agents that help businesses resolve conflicts faster, smarter, and with less overhead.
The product is already live, revenue-generating, and scaling fast across industries like manufacturing, telecoms, and financial services. Backed by top-tier VC investors (the same ones behind Monzo, Otta, and Wise), the company is growing its engineering team and hiring an experienced Staff Fullstack Engineer to help build scalable, secure, and well-architected systems across the stack.
You’ll join a small, product-driven team and play a critical role in both hands-on feature development and technical direction - including architecture, code quality, and mentoring.

Maintain a healthy, high-quality codebase through strong testing practices using Jest/Vitest for unit tests and Cypress for end-to-end.
-
Guide architectural decisions and contribute to long-term scalability and performance.
-
Mentor mid-level engineers, perform code reviews, and help shape a strong engineering culture.
