Job Title: Senior Mechanical Engineer – Precision CNC Machined Parts
Location: Southampton, England, United Kingdom
Company Overview:
Our client is a leading manufacturer of subsystems incorporating precision CNC machined parts, serving high-performance sectors.
Job Summary:
We are looking for a highly skilled Senior Mechanical Engineer with deep expertise in the design, development, and optimisation of precision CNC machined components. This hands-on engineering role focuses on technical excellence, collaboration with cross-functional teams, and continuous improvement in design and manufacturing processes.
Key Responsibilities:
* Design mechanical parts for CNC machining with a focus on functionality, tolerancing, and manufacturability (using SolidWorks)
* Apply GD&T standards for precision tolerancing of low-volume, high-value components
* Create accurate 2D/3D technical drawings and documentation to support production and quality control
* Perform static and dynamic mechanical analysis to validate structural integrity under real-world conditions
* Conduct thermal simulations and CFD to assess heat dissipation and optimise airflow design
* Specify and assess surface treatments and coatings for durability, optical performance, or thermal requirements
* Identify and implement design improvements to enhance part performance, manufacturability, and cost-effectiveness
* Support root-cause analysis and apply engineering solutions to production and quality issues
* Contribute to process improvement initiatives within machining and assembly workflows
Qualifications:
* Bachelor’s degree in Mechanical Engineering
* Approx 5 years of experience in mechanical part design and development, with a focus on CNC machined parts, including 3D CAD modelling and 2D drawing creation
* Proficiency in 3D CAD software (SolidWorks) and engineering analysis tools
* In-depth understanding of CNC machining processes, materials, and tolerances
* Solid grasp of GD&T, DFM/DFA principles, and industry best practices
* Skilled in performing mechanical analysis (static and dynamic) using tools like ANSYS, SolidWorks Simulation, or similar
* Strong problem-solving and communication skills
* Hands-on experience with thermal simulations and CFD tools for evaluating heat transfer and airflow
* Knowledge of manufacturing processes such as CNC machining, injection moulding, sheet metal, and 3D printing
* Familiarity with surface finishing techniques (e.g., anodising, coating, polishing) for functional or aesthetic purposes
Preferred:
* Professional Engineer certification
* Experience in regulated industries
* Familiarity with Six Sigma, Lean Manufacturing, or other quality improvement methodologies
Summary:
This is an excellent opportunity for a senior mechanical designer/ engineer to join a successful international organisation in its expanding phase, a leader in R&D and manufacturing of highly niche high-tech systems for a wide range of applications in life science, general industries, aerospace and the sky is the limit. The position will suit an enthusiastic professional looking for a great long-term career, and a people person. The company is truly international, so be prepared to put your language skills to use!
