Mid-Level Software Engineer

Location: San Francisco, California, United States

Department: Engineering, Product & Tech

Workplace: remote

Employment Type: full

Description

The organisation

A private foundation, established by the founder of a major technology company, working across education, health and climate. Its flagship education programme is a digital learning platform built in partnership with a leading international children's agency.

The platform reaches over ten million registered learners across more than forty countries — children, young people and teachers, many in places where it is the only route to structured education. It works online, on mobile, and fully offline, so learners in areas with no connectivity can carry on and sync when they reconnect. The ambition is fifty million learners by 2030.

The role

You would be the second engineer in-house, working alongside the Lead Software Engineer and an external technical consultant.

The platform is mid-migration. A legacy monolith is being progressively replaced by a modern Next.js and .NET stack on Azure, without interruption to learners already using it. In the last year the team has brought continuous integration in-house, containerised the legacy application for cross-platform local development, and established the architecture for V2. The engineering practice is young, and there is real scope to influence how it works.

You would be writing code from day one against defined feature work, with the Lead Engineer owning architecture. As V2 matures there is a clear route to owning larger features end to end.

A small team on a platform this size means unusually high leverage. It also means the work is hands-on and pragmatic rather than abstract. If you want to ship things that reach millions of people and see the effect quickly, this is a good place to do it.
