Autonomy, ownership, and direct impact

Founded in January 2025, Ocean Orchestra aims to be a force for good in ocean conservation and the ocean economy. Backed by leading SaaS, FinTech and Climate investors, this is an opportunity to apply modern tech to a huge global challenge. Oceans are 71% of our planet and central to climate health, yet receive only a fraction of the world’s investment, technology, and AI innovation. Ocean Orchestra is changing that.

Our founding team — Jeremy King, Simana Paul and others — have built businesses to global scale. Now, we’re focused on creating lasting, positive change for our planet.

Salary: £75K-£95K

Equity: Real ownership, significant upside potential.

Location: Remote-first overall, with regular in-person days in our London Victoria office. Wider remote or hybrid options very much available, with flexible arrangements for the right candidate. We have an office in London, for anyone who wants to work in an office.

Inclusion: We actively welcome applications from candidates of all backgrounds, experiences, and identities. We care about you - your skills, your values, your potential - what you can do, what you want to do, how you work, how you want to work. We believe diverse perspectives are essential to solving global challenges, so we're building a team that reflects the great diversity of our real customers and users across the world.
