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

Fast-growing EdTech scale-up seeking a hands-on software engineer to own the MERN stack codebase, diagnose and fix bugs end-to-end, manage one Support Engineer, and help scale from 260 to 1,000 schools. Modern office in Vauxhall, London.

• Spend most of your time in the codebase – diagnosing, debugging, and fixing live issues directly in React/TypeScript, Mongo and Node.js
• Own bugs end-to-end: identify the root cause, ship the fix, and make sure it doesn’t come back
• Work closely with the Engineering team to resolve issues in live environments – no formal QA function exists, so rigour here really matters
• Act as the escalation point for complex, high-impact incidents – delivering clear Root Cause Analysis (RCA) documents where needed
• Manage and mentor one Support Engineer, acting as their day-to-day line manager
• Define and own SLAs across customer tiers, ensuring proactive communication when issues arise
• Champion AI tools and automation to make the support function faster and smarter
• Use data and patterns from live issues to feed product improvement conversations
• Help build the processes and team to take the business from 260 to 1,000 customers

• Confident, hands-on developer – comfortable opening a codebase, understanding unfamiliar code quickly, and shipping fixes independently
• Strong frontend experience, particularly in React and TypeScript
• Working knowledge of the broader MERN stack: Node.js, MongoDB
• Background in either software engineering or technical support – what matters is that you code, not just identify
• Highly analytical – someone who wants to understand why something broke, not just patch it
• Experience with debugging tools, log analysis, and live environment investigation
• Comfortable managing or mentoring
• Strong written communication skills – clear and professional when things go wrong with customers
• Track record of using AI tools (Copilot, ChatGPT, or similar) to accelerate your work
• Thrive in a fast-paced scale-up where processes are still being built and ownership is everything
• Ideal: Experience working in or with the education sector
• Ideal: Familiarity with Google Cloud, Cloudflare, or CI/CD pipelines
• Ideal: Experience with React Native

• £50,000–£55,000 salary
• 6 monthly pay reviews
• 22 days holiday plus bank holidays, rising with service
• Uncapped training and development budget
• Modern office in Vauxhall – easily accessible
• Weekly team lunches
• Vibrant team with regular socials – pool, darts, drinks, and team retreats
• Opportunity to work in a uniquely high-performance team
• Regular Mario Kart action
