Job Description

Overview:

Ele ment Digital Engineering is a leading provider of specialist engineering design, simulation, build, and consultancy services supporting complex and novel system development across the Aerospace, Automotive, Energy, Built Environment, and Chemical Process industries. We deliver advanced technical solutions to clients across the UK and internationally -- from early concept and requirements definition through to detailed design, manufacture, and test.
We are seeking a capable and motivated

Mechanical Engineer (Fluid Systems

) to support the design, analysis, and development of complex mechanical and fluid systems. This role forms part of our growing in-house capability and involves delivering technically challenging work packages across multiple sectors -- primarily aerospace and defence, but also energy and emerging low-carbon technologies.
The position offers an opportunity to apply both analytical and practical engineering skills across the full development lifecycle -- from requirements-based design and 3D modelling through to structural analysis, prototype build, and test support. The successful candidate will work as part of a multidisciplinary team, collaborating closely with specialists in controls, electrical, and systems development to deliver robust, high-performance solutions.
This is a hands-on, on-site engineering role ideal for engineers who enjoy solving real-world challenges, developing designs that balance strength, manufacturability, and performance, and seeing their work progress from CAD to physical systems in active test environments.
Responsibilities:

Design and Analysis

Design, analyse, and develop mechanical systems involving fluid flow, structural integrity, and thermal management to meet performance, reliability, and manufacturability objectives.

Perform calculations to ensure the structural integrity of components and systems under mechanical and pressure loads.

Conduct fluid system sizing, pressure-drop, and thermal analyses using analytical methods and simplified 1D models.

Execute finite element analyses (FEA) to verify mechanical performance and structural margins in accordance with design codes and standards.

Produce detailed 3D models, technical drawings, and mechanical layouts using CAD tools (e.g., SolidWorks, Siemens NX, or Catia), ensuring clarity, manufacturability, and compliance with GD&T principles and design standards.

Component and System Specification
Select and specify mechanical and fluid system components (e.g., pumps, valves, fittings, actuators, seals, and sensors) based on system performance, compatibility, and safety requirements.

Specify materials, manufacturing processes, and tolerances appropriate to system operating conditions and environments.

Ensure all designs comply with relevant codes, standards, and internal quality and safety requirements (e.g., ASME, API, ISO, PED, DSEAR).

Integration and Collaboration

Collaborate across disciplines -- including electrical, controls, and manufacturing teams -- to ensure effective system-level integration and traceability through the full engineering lifecycle.

Participate in design and peer reviews, contributing to cross-functional problem solving and optimisation activities.

Build, Test, and Validation

Support the build and commissioning of systems, including prototype assembly, instrumentation setup, and validation of mechanical performance and fluid behaviour.

Analyse test data to confirm system performance and feed learning into iterative design improvements.

Documentation and Reporting
Produce design calculations, stress reports, technical drawings, and documentation to a professional standard suitable for both internal review and client delivery.

Support the creation of technical procedures, method statements, and validation reports as part of structured design assurance and verification activities.


Skills / Qualifications:
Bachelor's degree (BEng or equivalent) in Mechanical Engineering or a closely related discipline. Minimum 2+ years' experience in mechanical design and analysis, preferably within aerospace, energy, or high-integrity system development. Sound understanding of structural analysis, fluid dynamics, thermodynamics, and heat transfer. Experience specifying and structurally justifying pressurised equipment in accordance with PED or BPVC requirements. Proficient in 3D CAD and able to produce high-quality technical drawings and design documentation, with strong understanding of GD&T and manufacturing tolerances. Experience with FEA tools (e.g., ANSYS, Abaqus, Nastran) for component-level and system-level mechanical verification. Familiarity with fluid system components and their integration into mechanical assemblies. Experience working within structured engineering processes, including design reviews and documentation traceability. Strong communication and collaboration skills, with the ability to work effectively in a multidisciplinary environment.

Company Overview:

Element is one of the fastest growing testing, inspection and certification businesses in the world. Globally we have more than 9,000 brilliant minds operating from 270 sites across 30 countries. Together we share an ambitious purpose to 'Make tomorrow safer than today'.

When failure in use is not an option, we help customers make certain that their products, materials, processes and services are safe, compliant and fit for purpose. From early R&D, through complex regulatory approvals and into production, our global laboratory network of scientists, engineers, and technologists support customers to achieve assurance over product quality, sustainable outcomes, and market access.

While we are proud of our global reach, working at Element feels like being part of a smaller company. We empower you to take charge of your career, and reward excellence and integrity with growth and development.

Industries across the world depend on our care, attention to detail and the absolute accuracy of our work. The role we have to play in creating a safer world is much bigger than our organization.
Diversity Statement:

At Element, we always take pride in putting our people first. We are an equal opportunity employer that recognizes diversity and inclusion as fundamental to our Vision of becoming "the world's most trusted testing partner".



All suitably qualified candidates will receive consideration for employment on the basis of objective work related criteria and without regard for the following: age, disability, ethnic origin, gender, marital status, race, religion, responsibility of dependents, sexual orientation, or gender identity or other characteristics in accordance with the applicable governing laws or other characteristics in accordance with the applicable governing laws.



The contractor will not discharge or in any other manner discriminate against employees or applicants because they have inquired about, discussed, or disclosed their own pay or the pay of another employee or applicant. However, employees who have access to the compensation information of other employees or applicants as a part of their essential job functions cannot disclose the pay of other employees or applicants to individuals who do not otherwise have access to compensation information, unless the disclosure is (a) in response to a formal complaint or charge, (b) in furtherance of an investigation, proceeding, hearing, or action, including an investigation conducted by the employer, or (c) consistent with the contractor's legal duty to furnish information. 41 CFR 60-1.35(c)
