About the Team

Community Platforms & LMS is one of three teams within Product & Platform Engineering, responsible for building and maintaining the platforms that connect and support the B Corp network, including community engagement tools (currently B Hive) and learning/education platforms (B Academy). A Tech Lead leads the team and works closely with the department's shared Architecture function — the Solution Architect and Software Architect — to ensure technical standards and platform coherence across Product & Platform Engineering. This is an area of active evolution: while B Hive currently serves as the team's core community platform, the broader toolset supporting community and learning experiences is still being defined, and the team plays a key role in evaluating and shaping that direction going forward. Community Platforms & LMS is central to how B Lab connects, engages, and supports its growing global network of Certified B Corporations and partners, ensuring these platforms are reliable, scalable, and designed around the needs of the B Corp community.

About the Opportunity

As Lead Software Engineer for Community Platforms & LMS, you will serve as the Tech Lead for this team, reporting directly to the Director of Software Engineering. You will own the technical direction of the platforms that connect and support the B Corp network — including B Hive as the team's current community tool — architecting and building solutions, mentoring the engineers on your team, and partnering with the department's shared Architecture function to ensure these platforms scale as B Lab's global network grows. Given that the broader toolset for community and learning experiences is still evolving, you will play a central role in evaluating future platform options and shaping the team's technical direction going forward, making this a strong fit for someone who's energized by ambiguity and building from a less fixed foundation.
