Why join Marshall Land Systems in this role? This is an excellent opportunity for a Senior Mechanical Design Engineer who wants technical ownership, programme variety and the chance to influence real engineering outcomes. Our mechanical design engineers work on a wide range of specialist land systems, including deployable infrastructure, command and control modules, medical and support facilities, protected mobility solutions, mission systems and complex vehicle‑mounted equipment. You will use Autodesk Inventor for 3‑D CAD, detailed design and drawing production, and Windchill PLM for product data management, configuration control, engineering change and release.
The role is focused on the design, development, modification and support of complex physical products. It involves supporting bids, new product development, modifications, configuration control, production support, integration, trials and in‑service improvements. You will work on varied programmes – from structural design and welded frame development to packaging systems in constrained modules, manufacturability, integration or customer‑specific modifications. As a Senior Engineer, you will apply sound engineering judgement, guide others, make technical decisions and help maintain continuity of design intent across complex programmes.
Job Description
- Act as a Mechanical Design Subject Matter Expert across bids, projects and product modifications.
- Take technical ownership of mechanical design activities across varied programmes and product types.
- Produce, review and check mechanical design outputs, including 3‑D models, 2‑D drawings, item lists, product structures, design data and technical documentation.
- Use Autodesk Inventor to develop robust 3‑D models, assemblies, drawings and design solutions.
- Use Windchill PLM to manage product data, configuration control, engineering change, item data, Bills of Material and release activity.
- Support the generation of complex mechanical design architectures for new and existing product design concepts, from initial risk assessment and feasibility studies through to functional design freeze.
- Lead technical input into bids, modifications and project delivery activities.
- Generate, review and check technical documentation, including project plans, technical proposals, customer and supplier statements of work, design data and certification evidence.
- Apply sound systems engineering thinking to mechanical design activities.
- Work with stakeholder and customer requirements to derive internal design requirements.
- Develop mechanical approaches for modifications, upgrades and new project work.
- Provide technical leadership, coaching and support to mechanical design engineers and early‑career engineers.
- Support continuity of design intent and maintain configuration control across complex programmes.
- Support design reviews, technical reviews and change boards.
- Work collaboratively with programme, manufacturing, supply chain, quality, integration and operations teams.
- Support the resolution of technical issues during build, integration, trials and in‑service support.
- Help improve engineering quality, design standards, manufacturability and ways of working across the Mechanical Design function.
- Ensure compliance with regulatory, customer and company processes.
- Bring significant platform, product and regulatory experience to the efficient and effective completion of engineering data sets.
What makes someone successful here
We are looking for engineers who enjoy solving practical problems, working with others and taking ownership of their work. The best people in our team are curious, hands‑on, comfortable with detail and able to balance technical quality with programme needs. Your experience in aerospace, defence, automotive, rail, special‑purpose machinery, heavy engineering, structural fabrication, vehicle systems, marine, energy or other complex engineering environments is valuable. What matters most is your ability to think clearly, work from requirements, produce robust design solutions and collaborate across functions. If you are looking for a role where every project looks the same, this probably is not it.
Qualifications
Qualified to degree level in Engineering, Mathematics or Physics with relevant and sufficient experience in the field. Alternative qualifications and/or experience will be considered.
- Demonstrable experience working as a Senior Mechanical Design Engineer or experienced Mechanical Design Engineer within a complex engineering environment.
- Experience producing, reviewing or checking mechanical design data, including 3‑D models, 2‑D drawings, item lists, product structures and technical documentation.
- Experience using Autodesk Inventor for mechanical design would be beneficial. Experience with other 3‑D CAD systems will also be considered.
- Experience using Windchill PLM for product data management, configuration control, engineering change and release would be beneficial. Experience with other PLM or PDM systems will also be considered.
- Strong understanding of mechanical design delivery, including CAD modelling, drawing production, design checking, configuration management and release.
- Ability to apply sound systems engineering thinking to mechanical design work.
- In‑depth understanding of industry standard design practices such as tolerance assessment, design for manufacture and assembly, configuration management and design governance.
- Experience working from stakeholder or customer requirements to derive practical internal design requirements.
- Experience developing mechanical approaches for modifications, upgrades, new designs or complex project work.
- Ability to compile technical reports, certification documentation and supporting design evidence.
- Understanding of mechanical certification and validation methods, with the ability to identify appropriate means of compliance.
- Experience planning and delivering complex tasks to schedule and budget.
- Ability to manage priorities across multiple projects or work packages.
- Confidence to provide sound technical input based on facts, evidence and engineering judgement.
- Ability to support, coach and guide less experienced engineers.
- Experience in aerospace or defence would be beneficial, but we are also interested in engineers from other complex or regulated engineering sectors such as automotive, rail, heavy engineering, special‑purpose machinery, structural fabrication, vehicle systems, marine, energy or industrial equipment.
- Structural design experience would be beneficial, including understanding of structural theory and experience developing structural solutions, particularly for steel welded frames.
Benefits
The benefits we will offer you include 27 days holiday increasing with service up to 30 days, with the option to buy or sell leave; pension contributions up to 9%; private medical insurance; extensive flexible benefit programme including Cycle to Work; life assurance at 4× basic salary; enhanced parental leave and pay; paid volunteering leave; and access to industry‑leading wellbeing resources and tools.
