Roxel is an Anglo-French company that designs, develops and manufactures solid propellant rocket motors for use in tactical missiles. Its operations are spread across several sites in the UK and France and it has an annual turnover of about £130M and nearly 700 staff.


The UK operations are entirely based at Summerfield, Kidderminster, where we have a vacancy for a permanent stress engineer in the rocket motor design team.Candidates are sought that seek to build a rewarding career in rocket motor design and manufacture. The vacancy has the potential to be either a junior position ranging to a senior position within the team depending on the level of relevant experience. The candidate will report to the Design Manager within the Engineering department. Relevant experience in rocket motor design and modelling is not expected, candidates interested in moving into this new and exciting field are encouraged to apply.


The successful candidate will work as part of the wider Roxel team on all phases of the project life cycle including design, demonstration, development, production and customer support. Be the structural technical authority for several rocket motor products. Work will mainly include conducting Finite Element Analysis (baseline software is Abaqus) of rocket motor hardware (metals, rubber/rigid insulants, bondlines) and the energetic propellant charge. Therefore, knowledge of material science and engineering would be advantageous, including non-linear viscoelasticity.


The role will involve the following activites:


– Responsible for the analysis of new and existing rocket motor systems which may involve, hardware and propellant charge structure analysis, CFD and thermal analysis.
– Responsible for hardware and charge analysis including finite element analysis modelling, calculation of safety factors.
– Able to use relevant software and programming techniques, including: Abaqus, Fortran and Matlab.
– Provide technical advice to the project on rocket motor design from a structural specific perspective.
– Rheological analysis of material testing and providing advice to the technical community.
– Development of motor structural testing plan and involved in the delivery and assessment of the structural testing results.
– Responsible for the structural performance technical authority aspects of assigned projects, including supporting project customer meetings, project investigations, design reviews, and corresponding customer stress engineers.
– Deliver key project documentation including, structural analysis and structural test plans and reports and structural design records.
– Contribution to qualifications report using expert knowledge.
– Responsible for keeping updated with industry technical innovations and changes, building on their expertise, and acting as the technical lead of new technology research programmes, and the on-time delivery and cost of the programme and interfacing with the customer.
– Schedule, plan and prioritise their work and time to ensure on time delivery of tasks.
– Responsible for the update and maintenance of job list and the associated on-time delivery metric.
– Identify risks and issues that may impact delivery, including time, quality and cost, and communicate solutions with the Design Manager.
– Take responsibility for Health and Safety in Roxel UK.
– Additional duties or tasks as requested by business requirements.


Roxel are the European leader in the design and manufacture of rocket motors. Candidates will be encouraged to get involved in all aspects of a rocket motor’s project life cycle including design, demonstration (small scale and motor firing trials), development, production and customer support. The whole rocket motor design and manufacture cycle is contained within the Summerfield site. Therefore candidates have the opportunity to be involved in concept design, modelling analysis, product development and testing, engineering, material science and research and development.


• Educated to degree level with relevant Engineering (e.g. Mechanical, Aerospace, Structural) or Material Science.
• Proficient in the use of FEA software (preferably Abaqus).
• Material science knowledge (metals, composites, viscoelastic materials, adhesives, manufacturing methods).
