Job description

We’re supporting a disruptive EdTech SaaS startup to land their 1st Full-time, permanent Engineering hire!

This is an opportunity to get in at the ground-floor of a startup that’s making waves in the Education sector with their Operating System for teachers. Their platform brings pupil information together and strengthens connections between teachers and parents.

They’ve just closed a fundraising round, and are looking for the person who can help them build what comes next. They’re just getting started…

The role

This is not a “here’s your ticket, go build it” job.

As the first senior engineering hire, you’ll have genuine ownership. You’ll work directly with the co-founder to understand the problem, shape the solution, make the technical decisions, build it, test it and get it into production.

You’ll work across:

Infrastructure : AWS

(You’ll also work with integrations including Wonde, Postmark, Twilio and Daily.)

What they’re looking for

Someone who:

• Can take a feature from idea → production with minimal hand-holding


• Cares deeply about quality and user experience


• Is comfortable owning their own QA — no separate QA team here


• Can spot bugs, performance issues and technical debt before they become problems


• Enjoys making architectural decisions and thinking about how systems scale


• Writes clean, maintainable code


• Communicates clearly and can translate technical thinking for a non-technical co-founder


• Wants their work to have a visible impact

You won’t be joining a huge engineering org where your work disappears into the backlog.

You’ll be one of the people shaping the product, engineering culture and technical foundations from the ground up.

If you’re a senior full-stack developer in Northern Ireland who wants real ownership, real influence and the chance to build something that could genuinely change how schools operate, i’d love to hear from you.

Hybrid 2 days in Belfast.
