The Company

Based in Marchwood, Southampton, Stanelco RF Technologies (Stanelco) is a division of Biome Technologies plc.

Stanelcos small, multidisciplinary team specialises in the design and manufacture of bespoke engineering solutions for a wide range of industries utilising induction heating and dielectric welding systems.

With a strong focus on high-frequency RF technologies, projects typically range from £50k to £500k+ and include RF heating systems, electrical and electronic control systems, and integrated mechanical handling solutions for the Medical, Industrial and Nuclear sectors. Delivery timelines vary from 3 to 12 months, covering the full process from project acquisition through to commissioning and compliance.

The Role

Reporting to the Head of Engineering, the successful candidate will operate as a key member of a multi-disciplinary engineering team, with technical ownership of the mechanical design and development of complex industrial process equipment, from concept through to manufacture, installation, and commissioning. The role includes exposure to electromechanical systems, thermal and dielectric processing, and bespoke machinery.

You will own the mechanical design process and CAD system (Solid Edge), including standards, best practices, and design release.

Candidate Profile

Given the size and nature of the business, this role offers some flexibility and can be tailored to the skills and experience of the successful candidate. We welcome applications from experienced Senior / Lead Engineers who can provide authoritative leadership across mechanical design, safety, and compliance.

Ideally, you will be educated to degree level (or equivalent) in Mechanical Engineering and have several years demonstrable experience in the development and integration of industrial machinery or bespoke process equipment. You will be a natural problem-solver, comfortable operating in a hands-on, project-driven engineering environment.

Key Design Responsibilities

Design of bespoke machinery, translating customer and product requirements into robust mechanical designs that meet performance, safety, and regulatory expectations.

Design and integrate appropriate material handling systems, including part loading/unloading, fixturing, alignment, and operator interaction.

Work closely with the Head of Engineering and the Electrical Engineering team to ensure correct mechanical integration of RF generators and electrical components.

Technical Skills & Experience

Strong proficiency in 3D CAD and 2D drawing production and part management using Solid Edge (SolidWorks, Inventor, Creo, or similar).

Experience designing and integrating dielectric (RF) heating and welding systems or closely related thermal or high-voltage process equipment.

The design of sheet metal components and assemblies including frames, enclosures, panels, guards, and structural elements.

Experience designing mechanical aspects of electronic packaging, including enclosures, mounting, and thermal considerations.

Strong understanding of manufacturing processes, tolerancing, and DFM/DFA principles.

Design of systems requiring hydraulics and pneumatics.

Design of conveyor/material handling systems.

Selection and integration of motors, gearboxes, and drive systems including stepper and servo motors.

Experience working with third-party suppliers, contract manufacturers, and external vendors.

Additional Skills & Experience (Advantageous)

Experience acting as a technical lead or design authority.

Exposure to on-site installation, commissioning, and fault-finding.

Familiarity with machinery safety standards and compliance requirements such as CE and UKCA.

Experience managing supplier technical queries, design changes, and quality issues.

Documentation, Compliance and Quality

Generate and approve technical documentation including detailed drawings, BOMs, design calculations, tolerance analysis, and risk assessments.

Ensure designs comply with relevant machinery safety standards and internal engineering processes.

Support compliance activities including CE and UKCA marking.

The Opportunity

This is a rare opportunity to play a critical technical role within a highly specialised engineering company with a global reach, influencing technical direction, product safety and compliance, and long-term engineering capability while working on challenging, bespoke solutions.

Compensation & Benefits

A competitive base salary, commensurate with experience, plus an attractive benefits package.
