Senior Software Engineer (Full Stack)

Ocean Infinity · London, United Kingdom (Hybrid) · Full-time · Posted 2026-09-15

Salary: GBP 110,000–110,000

Workplace: hybrid

Department: SUPERVISORY_ORGANIZATION-3-1628

Description

At Ocean Infinity, we're on a bold mission to subsea data using innovative technology.

Using cutting-edge robotics, autonomous technology and world-class software, we're transforming how complex operations are carried out at sea. Our uncrewed systems are making ocean exploration and operations safer, smarter and more sustainable, helping unlock the vast potential of our oceans while reducing environmental impact. 🌍

This isn't a vision for the future. It's happening right now.

As we continue to push the boundaries of innovation and redefine what's possible in the maritime industry, we're looking for exceptional talent to join our fast-growing team.

Ocean Infinity is seeking a hands-on Senior Software engineer with Tech Lead hat experience for a fullstack product team. You are the technical anchor of the team: you own how the work gets built and when it ships, while remaining a strong individual contributor. We are looking for someone assertive and entrepreneurial who takes initiative, digs for answers, and helps the team navigate complex problems rather than waiting for direction.

As with our Senior Engineers, this role is backend-first and stack-plural. Our products run on C#/.NET with React, and on our TypeScript stack (Next.js, tRPC, Node, Postgres). You should be strong enough in backend engineering to set and hold the quality bar wherever the team is building.
