Job description

Mechanical Design Engineer – Maritime Defence

Location: Hampshire

Employment Type: Permanent

The Role

A leading global developer of advanced maritime defence and underwater sensor technology is looking for a Mechanical Design Engineer to join its specialist engineering team.

In this role, you will play a key part in designing industry-leading underwater sensing, tracking, and domain awareness solutions. Working closely with cross-functional engineering and project teams, you will step into active development workflows, taking ownership of mechanical design tasks, 3D modelling, detailed drafting, and prototype part procurement to deliver mission-critical defense solutions worldwide.

Key Responsibilities

• Develop and deliver mechanical design solutions, 3D models, and assemblies for subsea and maritime technology.
• Produce, review, and validate detailed engineering drawings to BS 8888 standards with a high level of accuracy.
• Source prototype components and liaise directly with suppliers regarding manufacturing feasibility, lead times, and specifications.
• Collaborate closely with multi-disciplinary engineering and project management teams throughout the full product development lifecycle.
• Apply fundamental engineering principles and problem-solving techniques to overcome technical challenges.
• Ensure all design outputs comply with stringent quality, manufacturing, and defence industry standards.

About You

The ideal candidate will have:

• A degree in Mechanical Engineering (or equivalent qualification).
• At least 4+ years of industry experience within product development or mechanical design.
• Strong proficiency in 3D CAD software (SolidWorks and/or Autodesk Inventor preferred).
• Expertise in creating and interpreting standard engineering drawings to BS 8888.
• Sound knowledge of traditional and modern manufacturing principles and production processes.
• Strong communication skills and the ability to operate independently with minimal supervision.

Security & Eligibility Criteria

Due to the sensitive nature of the defence projects supported:

• Due to the nature of the defence projects supported, candidates must be UK Nationals and eligible to hold UK Security Clearance (SC). Dual nationals cannot be considered due to client security requirements.
• Must have continuously resided in the UK for the last 5 years.
• Prior experience using MRP / ERP systems.
• Background in subsea, oceanographic, marine, or aerospace/defence engineering environments.
