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.

 

About the Company:

  • As a small but growing team, the day to day can be quite varied; this role is ideal for someone who likes to work on a range of responsibilities rather than being pigeon-holed.
  • They are a tech for good and deliver education to students in under-privileged areas in Africa.
  • Having worked with this company for the last 6 years, I have found that they have a really nurturing culture with approachable and down-to-earth senior leadership.
