Job description

Board Intelligence is a technology and advisory firm that supercharges boards with the science of board effectiveness. We build better businesses and benefit society.

Through a suite of AI-powered software tools, evaluation frameworks, and advisory services that distil twenty years of boardroom experience, we improve the efficiency of board processes and the effectiveness of boards.

We work with over 70,000 leaders and 3,000 organisations across the world, with clients across the Fortune 500, FTSE 100, and OMX 30. In 2024 we received substantial backing from K1 Investment Management – the leading B2B Enterprise SaaS investors. We are at the beginning of significant growth, and we’re looking for superb talent to join us on this journey.

As we grow, we’re fiercely protective of our culture and values. Many of us, including our founders, have families and other priorities, so we know the value of a supportive company.

The team is diverse and friendly. We value fun: most days you’ll find a social event or learning opportunity to get involved with, including company socials, away days, philanthropic activities and lunch & learns.

Our Mission

We unleash the potential of organisations through the science of board effectiveness, building better businesses and benefiting society.

The Role

The role requires someone who can quickly add value, take ownership of complex challenges, and guide the team through the delivery of varied projects, including AI-driven features, internal tools, and systems where security and reliability are critical.

This is a role for someone who enjoys balancing speed with technical rigour, thrives on exploring innovative ideas, and is motivated by helping others grow. You will not only contribute through your own coding expertise but also by amplifying the impact of the entire team.

By joining us, you will help shape a team that ships high-quality, secure, and innovative software quickly. You will play an active role in ensuring we can confidently pursue new opportunities, experiment with new technologies, and grow into a stronger, more capable development team.
