Job description

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 company

Our 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 role

This 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. But make no mistake: the core expectation is someone who can open the codebase and own the fix.

Day-to-day includes:

• 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

The package

• 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 – if you’re impatient for progress, this is the place you’ll thrive

To be successful, you will…

• Be a confident, hands-on developer – comfortable opening a codebase, understanding unfamiliar code quickly, and shipping fixes independently
• Have strong frontend experience, particularly in React and TypeScript
• Have working knowledge of the broader MERN stack: Node.js, MongoDB
• Have a background in either software engineering or technical support – what matters is that you code, not just identify
• Be highly analytical – someone who wants to understand why something broke, not just patch it
• Have experience with debugging tools, log analysis, and live environment investigation
• Be comfortable managing or mentoring
• Have strong written communication skills – clear and professional when things go wrong with customers
• Have a 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, but not essential…

• Experience working in or with the education sector
• Familiarity with Google Cloud, Cloudflare, or CI/CD pipelines
• Experience with React Native
