Job Description:

Principal/Staff Engineer

We are helping an edu‑tech company who are looking to scale up the development team with a Principal or Staff Engineer. This is a hands‑on development role which also includes AI strategy, code reviews, and understanding business strategy.

About you

  • Hands‑on enough to contribute directly in C# / Backbone / Ms SQL.
  • Able to reduce key‑person dependency across the platform.
  • Pragmatic about AI‑enabled engineering workflows.
  • Good communicator with enough gravitas to influence without creating friction.
  • You will be a senior technical operator. Someone who is hands‑on enough to materially strengthen delivery resilience, while also bringing enough maturity to help us improve how we use AI within the team.

About the role

  • This is a hybrid position but there will be times when you need to be in the office more than at home, depending on deadlines.
  • You will be an individual contributor, sitting in on sprints and understand how to resolve poor performing queries.
  • We are looking for a full stack engineer who cares about the UX and UI.
  • The ideal Principal Engineer will have a genuine interest in the business, rather than have a ‘code and go home’ mentality.
  • The role involves working collaboratively with the development team and also getting hands‑on with the data’s underlying quality, clean data errors, build trust in the outputs, tighten operational discipline, and strengthen inputs to stop data quality issues reappearing – not just being focused on feature delivery.
