Site Agent; Marine Civils

Site Agent (Marine Civils) – TMS Maritime

We’re hiring a Site Agent due to continued project demand and to strengthen on-site delivery across the UK.
If you enjoy varied sites, real responsibility, and work that stands up to tide, weather and time, this is your next move.

Why TMS Maritime:

TMS Maritime is a UK marine construction and civil engineering contractor delivering coastal and inland infrastructure-think seawalls, quay piling, dredging, flood defences and harbour works-with a “can-do” approach and a strong focus on safety, quality and value.

You’ll be part of a business that’s big enough to deliver major projects, and small enough that your contribution is visible and valued.

The Role:

As Site Agent, you’ll take day-to-day ownership of site delivery-keeping people safe, works on programme, and quality right-first-time.

Key responsibilities include:

Leading daily site activity (labour, subcontractors, plant, materials), including logistics and traffic management.

Running briefings and toolbox talks, maintaining a proactive HSE culture and completing inspections/audits.

Managing technical delivery: drawings/specs, ITPs, inspections/testing, and resolving issues with the wider engineering team.

Tracking progress, short-term planning, and producing clear daily/weekly reporting.

Coordinating stakeholders on site (clients, suppliers, subcontractors) and supporting commercial teams with accurate site data.

The “marine difference”: projects can be driven by tidal access, so you may work in blocks (for example, a working window, a break, then a second window). If you like problem-solving and planning around real-world constraints, you’ll enjoy this.

Location, hours & working pattern

Location:

Various sites across the UK, with occasional travel to TMS Maritime’s Dawlish HQ (EX7) as needed.

Hours:

Core site hours are typically 07:30–17:30, with longer days/ extended working hours possible depending on programme/tidal windows.

Overtime:
Paid overtime with enhanced rates (including weekend working where required), creating strong earning potential.

Travel:
This is a site-based role and will include overnight stays depending on project location.

What you’ll get:

Up to £55,000 salary
- Depending on experience

Company car with personal use

Paid overtime (including enhanced rates), with the opportunity to increase total earnings on busy programmes.

Two bonus opportunities: an annual bonus (around 10%) plus a long-term incentive programme linked to business performance.

Holiday: 23 days annual leave (plus bank holidays)

Progression:
Potential to progress into a  Site Manager position and onward into broader project/contract leadership as you grow.

Varied, meaningful work: projects that protect coastlines, maintain vital infrastructure, and keep ports/harbours operating.

What we’re looking for:

HNC/HND or Degree in Civil Engineering, Construction Management (or similar).

CSCS (Site Manager/Supervisor level) and SMSTS.

3–5+ years’ site management/supervisory experience (civil engineering or marine infrastructure ideal).

Confidence leading people on site-clear communication, steady decision-making, and the ability to build respect with varied teams.

Full UK driving licence – maximum 6 points.

Desirable:
First Aid at Work, Temporary Works Supervisor, and marine/civils contract knowledge (NEC/JCT).
