Cirrus Selection Limited; Ampthill; On-site; GBP 40,000 - 45,000; Full time

Job summary

Cirrus Selection Limited seeks a Manufacturing Engineer focused on NPI and process at our Ampthill site in Bedfordshire. You’ll join an Operations Engineering team, closing the gap between design for manufacture and build reality while supporting prototype through to full-rate production.

You’ll apply DFM, develop processes, and own PFMEA to ensure robustness. The role includes BOMs, SAP routings, tooling needs, and continuous improvement with a defence sector focus.

Qualifications

• Experience as a Manufacturing Engineer, Process Engineer or similar working on complex assemblies.
• NPI experience taking products from prototype into production.
• Practical use of PFMEA and quality improvement tools.
• CAD skills for producing 2D technical drawings.

• Experience writing clear process instructions or work instructions.
• Track record of driving process change that improved efficiency or quality.
• Eligibility for SC security clearance.

Responsibilities

• Join early design reviews and apply DFM so complexity, cost and lead time come out before anything reaches the shop floor.
• Develop manufacturing processes for new and existing products, and own the PFMEA that proves they’re robust.
• Define the sequence of operations, process instructions and production layouts, with lean manufacturing flow built in.
• Create manufacturing BOMs and routings in SAP.
• Identify tooling and fixture needs, write Technical Requirement Specifications, and support capital equipment from definition through to acceptance.
• Produce Basis of Estimates for engineering and shop floor activity.
• Feed simulation models into a digital twin that tests throughput and cost before decisions get made.
• Support full rate production and drive yield and continuous improvement, working closely with Industrial Engineering and Production Engineering.
