Software Engineer (Support & Quality) – Own the codebase, fix the problems, and help scale a fast-growing EdTech

Are you a confident software engineer who's tired of being handed a ticket and told to wait for someone else to fix it? Want to own problems end-to-end, get deep into a MERN stack codebase every day, and genuinely shape how a scaling product holds together? This might be the role for you.The companyOur client is a fast-growing EdTech scale-up on a mission to fix the chaos of school management. Schools are juggling siloed systems that don’t talk to each other – creating duplication, frustration, and wasted time. They’re changing that with one AI-powered platform covering everything from club sign-ups and attendance to parental consent, medical data for trips, and real-time notifications.They started by dominating music department management and are now scaling that approach to manage all aspects of the schools, from parents’ meetings to trips to clubs to behaviours to assignments.Over 260 schools are already on board – and they’re building towards 1,000. The team is close-knit, ambitious, and based in a modern office in Vauxhall.The roleThis is a developer role – not a support role with some coding on the side. Most of your time will be spent in the codebase: diagnosing bugs, understanding root causes, and shipping fixes directly in React/TypeScript, Mongo and Node.js. You’re not here to escalate – you’re here to solve.You’ll also manage one Support Engineer and be the face of the company to customers when things go wrong – communicating clearly and with urgency.
