Job Description

Closing Date: 23rd Aug 2026

Location: Birmingham, London, Ipswich

About the role

BT operates one of the UK’s most critical subsea cable estates. Working in the BT Subsea team therefore means contributing to the protection of the UK’s domestic and international connectivity as well as playing a key role in the evolution of BT’s UK and global connectivity. BT works hard to ensure its networks remain resilient, available, and ready for the future. As the Subsea Marine Delivery Specialist, you will play a vital role in protecting this critical infrastructure.

This role will be responsible for the safe, efficient, and commercially effective delivery of marine and subsea activities across the asset lifecycle, including planning, installation, inspection, maintenance, upgrade and retirement of subsea cable systems and associated infrastructure. The role provides leadership and coordination of offshore execution activities while managing interfaces with consortium partners, marine contractors, project teams and regulatory stakeholders to ensure successful delivery of strategic asset objectives.
Alongside the Subsea Integrity and Operations Manager and Subsea Asset Strategy Lead, this role blends technical strategy, commercialisation, product thinking, and critical infrastructure risk management to build a subsea platform that is fit for the next decade of growth, resilience, and competitive advantage.

You will be joining a team that’s rebuilding capability, investing in new technologies, and shaping the future of subsea operations. After years of underinvestment, this and other roles within the team have been created to ensure BT Subsea are able to deliver on the strategy of Operational Excellence, Resilience, Commercial Value, and Innovation.
The successful candidate must be a decisive technical leader who is capable of balancing risk, safety, operational readiness, commercial obligations, and system resilience while making rapid, high quality decisions that protect the subsea cable network, BT and the UK.

This role requires DV eligibility

The role is hybrid (3 days in office) & can be based in either: Birmingham / Ipswich / London
