Senior Mechanical Design Engineer

Job description

Senior Mechanical Design Engineer

Overview

An established engineering organisation specialising in complex mechanical systems is seeking an experienced Senior Mechanical Design Engineer to join its design team. The company develops bespoke, high-performance engineered systems supplied to customers worldwide and operates across a full design-to-manufacture lifecycle.

This role focuses on the design and delivery of mechanical sub-systems and assemblies, producing complete manufacturing packages including drawings and bills of materials. You will take ownership of work packages, collaborate closely with project, production, and supply chain teams, and contribute to continuous improvement across products and processes.

The Role

You will be responsible for designing and developing mechanical assemblies and “system elements” for complex engineered systems. When assigned ownership of a work package, you will act as the lead engineer for that scope, managing delivery to time, cost, and specification. The role combines hands-on mechanical design, technical coordination, and close interaction with manufacturing and suppliers.

Depending on project needs and experience level, you may also support production, suppliers, and service teams, and help mentor more junior engineers.

Key Responsibilities

Design mechanical assemblies and sub-systems and produce full manufacturing packages (GA drawings, detail drawings, BOMs, documentation)

Ensure designs meet functional, regulatory, and compliance requirements (e.g. Relevant machinery and pressure equipment standards)

Apply Design for Manufacture and Assembly (DfM/DfA) principles, including serviceability and lifecycle considerations

Work with project and supply chain teams to agree manufacturing methods and procurement routes

Lead or contribute to design reviews and technical decision-making

Create and maintain technical documentation, including design files, calculations, and compliance evidence

Support production and test activities, including build, verification, and troubleshooting where required

Contribute to continuous improvement activities, design standards, and engineering best practice

When acting as lead for a work package, track progress, manage issues, and communicate status to stakeholders

Support risk assessments, method statements, and technical documentation as needed

Required Qualifications & Experience

Degree, HND, or equivalent experience in Mechanical Engineering or a related discipline

Significant experience in mechanical design within a manufacturing or engineered-systems environment

Strong experience using 3D CAD software (SolidWorks or similar)

Proven ability to produce high-quality manufacturing drawings and documentation to relevant standards

Good understanding of GD&T, limits and fits, and tolerance analysis

Experience selecting materials and manufacturing processes to balance cost, lead time, and performance

Comfortable working in a multi-disciplinary engineering environment

Technical Skills & Knowledge

Experience designing machined and fabricated components and mechanical assemblies

Ability to carry out basic stress analysis and engineering checks (e.g. Using FEA or hand calculations)

Experience building and maintaining BOMs and working with MRP/ERP systems

Understanding of compliance, quality systems, and structured engineering processes

Proficient with standard office software (Word, Excel, PowerPoint, Outlook or equivalents)

Experience updating or working with legacy 2D data is beneficial
