We’re on the look out to add a Senior Mechanical Engineer to our elite workforce

Aerospace and defence equipment wouldn’t be able to operate if it wasn’t for avionic manufacturers like Chelton.

We pride ourselves on working with customers and being attuned to industry trends to expand the possibilities of aerospace and defence and give our customers a helping hand in achieving mission success. Working in challenging environments, producing failsafe technology with smart thinking – it’s just what we do. But we couldn’t do it without the Chelton A-team

In this role, you will be expected to be creative and innovative in the generation of concepts and detailed designs using 3D CAD and FEA & CFD simulation tools. We are looking for an engineer capable of designing products, critiquing, developing and following the process through to delivery. Someone with tenacity, attention to detail and capable of leading their own projects autonomously. 

We are even willing to support your training requirements by offering access to ILM, FEA or PDM courses and support you on your journey to achieving Chartered Engineering status. 

You will provide expert technical guidance to the mechanical design team, supporting the Chief Mechanical Engineer in maintaining a high quality technical output on time and to cost.

As a Senior Mechanical Engineer, your key responsibilities will include:

  • Produce detailed designs using 3D CAD and use FEA and CFD tools to simulate mechanical behaviour
  • Undertake tolerance analysis of designs including Geometric Dimensioning and tolerancing.
  • Generate and amend drawings and documentation to appropriate standards including BS8888 and Bills of Materials.
  • Investigate and define answers to design problems via NCR’s from manufacturing.
  • Produce documentation to support CDRL (Contract Data Requirements List)
  • Conduct risk analysis
  • Use FMEA (Failure Mode and Effects Analysis) to diagnose faults
  • Act as Lead Engineer on projects and bids when required
  • Continuous improvement of processes and tools including support to corporate change initiatives

As a Senior Mechanical Engineer your skills and qualifications will ideally include:

  • Experience of engineering product life cycle and development phases.
  • Experience of using 3D CAD packages, use of Solidworks would be an advantage
  • Rounded overview of mechanical engineering, including structural analysis and CFD (predominantly thermal). 
  • A broad understanding of materials, treatments and finishes and their environmental implications
  • Knowledge of composite design and production techniques (ideally GFRP)
  • Proven ability to support sustainability; to re-engineer, modify and support production. 
  • Experience gained from aerospace, automotive, medical or similar regulated industry


  • Competitive salary
  • 25 days holiday, plus bank holidays, with the opportunity to buy and sell leave
  • Flexible benefits scheme including private medical insurance and cycle to work scheme
  • Pension contribution matched up to 8%
  • Flexible working

This role will be based at our headquarters in Marlow, Buckinghamshire.

No two days are ever the same at Chelton, you’ll constantly be faced with new challenges to overcome. From the very beginning, you will be able to take full ownership and accountability to see products through to success. After all, where would we be if it wasn’t for the people behind the products?

If you’re looking to leave your mark on the world, why not choose the exhilarating world of aerospace and defence and better yet, join Chelton for your chance to innovate, create and excite.
