We are an ambitious team incubated and supported by ImpactEd Group. The role would be employed by TEP Services Limited. Our platform has been built from the ground up by a small, skilled development team over the past three years. We are appointing a Senior Rails Engineer at a pivotal moment, joining as a senior individual contributor with strong influence on product planning and the roadmap, owning two products in the TEP ecosystem, and acting as the senior technical reference point for the wider development team. You will work closely with our fractional CTO and the TEP Director to translate strategic priorities into well-built software, helping us actively embed AI-assisted development practices that we believe will significantly change how our team works over the next two years. Supporting our early- to mid-career developers in their work comes alongside the technical role. We are a small, mission-driven team and this is a high-trust, high-ownership role. The right person will care about the quality of what they build, be genuinely curious about the problems schools and trusts are trying to solve, and be excited about using AI tooling not as a shortcut but as a genuine accelerant for good work. What you ll inherit A proven, established codebase. Three years of well-considered Ruby on Rails development serving 600+ schools across the UK, Australia and the UAE, with active users, real data, and a roadmap shaped by partner feedback.
