Senior Software Engineer (FullStack) in London

About Birdie

At Birdie, we’re reimagining care for older adults. We’re building the technology that powers the future of home healthcare, empowering care teams with tools to deliver better, more dignified care, and enabling older people to thrive in their own homes for longer. Our all‑in‑one solution powers millions of care visits every month, equipping care providers with the tools they need to deliver exceptional, efficient care. We’re not here to tinker at the edges. We’re here to radically transform a broken system. That’s why we’ve built an all‑in‑one platform that supported over 60 million care visits and enabled care for 116,000 individuals in 2025, and we continue to grow our impact. We’re scaling fast, but staying true to our purpose. We’re proud to be a B Corp, using business as a force for good.

Your mission

Rostering is one of the most complex and consequential parts of what we build at Birdie. It’s the system that decides how thousands of care workers spend every minute of their day, which means when it works it powers safe, on‑time care for older adults receiving support at home. When it doesn’t, people miss visits. We’ve grown beyond what our first version can support, and we’re rebuilding it as Rostering V2: the operational backbone we want our partners to depend on for the next ten years. As a Senior Full Stack Engineer, your mission is to own and ship Rostering V2 features end‑to‑end. You’ll work alongside a Staff IC and four senior engineers, writing TypeScript and React on the frontend, Node.js (and Go as you ramp) on the backend, partnering with Product to translate care‑management requirements into reliable software. Your early success will be measured by shipping meaningful Rostering V2 features, confidently handling the on‑call rota, and improving code quality through clean standards, sharper tests, and respected architectural decisions.

How you will contribute

• Own full‑stack feature delivery for Rostering V2, taking features from technical design through to production under high volume and complexity.
• Partner with Product to shape what gets built and when, breaking down epics, surfacing constraints, and influencing priorities.
• Contribute to engineering quality and architectural direction through code reviews, TDD practice, technical design input, and setting squad standards.
• Ramp quickly on the Rostering domain, ship work within the first 30 days, and take on the out‑of‑hours rota by 90 days.

Qualifications

• Strong full‑stack TypeScript and React experience, with known experience building scalable Node.js APIs.
• Comfortable across the full stack, from database schema to frontend component.
• Experience with TDD and writing tests first, with a clear rationale for testing.
• Ability to drive features to stable production deployment without constant oversight, flagging risks early and communicating trade‑offs to non‑engineers.
• Hands‑on with legacy and new codebases, willing to refactor and understand existing work.
• Go experience is a strong plus; if unfamiliar, a demonstrated keenness to learn and a track record of adopting new tech.
