We’re looking for a Senior Estimator to join the team at TMS Maritime, a leader in marine civil engineering and coastal infrastructure. This opportunity has arisen due to continued growth and project success, as we expand our capability to deliver some of the UK’s most complex and rewarding marine engineering schemes. You’ll enjoy a salary up to £75,000 plus bonus, company car, pension (matched up to 10%), life assurance & healthcare, along with hybrid working options and the chance to make a real impact in a collaborative, people-first culture.
If you’re passionate about cost planning and marine construction - and ready to lead bids that shape the nation’s ports, harbours, and coastlines - this could be your next move.
About TMS Maritime: TMS Maritime embodies an aspirational spirit rooted in innovation and responsibility. We strive to lead the marine civil engineering sector through technical excellence, sustainability (we’re the very first and only marine civils contractor in the UK to be officially certified Stage 1 and Stage 2 carbon neutral) and social impact. Our team culture reflects a strong sense of family and inclusivity, where collaboration, safety, and mutual respect are paramount. You’ll be joining a team that values individual contribution, supports professional development, and works together to deliver lasting results, encouraging everyone to reach their potential. This unique DNA combines technical excellence with community engagement, whether through apprenticeships, charity initiatives, or environmental stewardship, creating a workplace that is both purpose-driven and people-focussed.
The Role: As Senior Estimator, you’ll lead the estimating process for high-value marine civil engineering projects - from concept through to bid submission. Working closely with the Head of Estimating, you’ll provide hands-on technical input and commercial insight to ensure all tenders are accurate, competitive, and risk-aware. You’ll collaborate across multiple departments - including engineering, planning, and commercial - to develop realistic programmes, identify value engineering opportunities, and support pricing strategy at board level. This is a highly visible role within TMS Maritime and offers the opportunity to influence how we win, plan, and deliver projects nationwide.
