This is a critical hire following the departure of a highly senior engineer and represents an opportunity to step into a genuinely influential position within a 20-strong engineering function.

This role sits at the centre of new product development. It is not an IT systems position. You will be responsible for bringing together electronics, embedded software, mechanical design and clinical functionality into safe, compliant and high-performing medical devices used worldwide.

Good systems engineers are rare. We are looking for someone who genuinely understands how complex products are architected, integrated and verified - not someone who simply understands the terminology.

You will:

  • Define and structure system-level requirements based on user, regulatory and clinical needs
  • Develop product architecture and clearly define subsystem interfaces
  • Lead system-level reviews and technical integration activities
  • Drive structured risk management and ensure appropriate mitigations are implemented
  • Oversee system verification and validation strategy
  • Maintain high-quality design documentation for regulatory compliance
  • Work cross-functionally with software, electronics, mechanical, quality and manufacturing teams
  • Support design transfer into production

You will act as the technical connector across disciplines, ensuring the product works as a cohesive, safe and commercially viable system.

What We’re Looking For

  • Proven experience as a Systems Engineer within medical devices or a highly regulated industry
  • Strong understanding of design controls and risk management
  • Experience integrating hardware and embedded software into complex products
  • Confidence leading technical discussions and system-level reviews
  • Structured, analytical approach with strong documentation skills
  • Familiarity with relevant regulatory standards is advantageous

Location & Working Pattern

Hybrid model: 2 days per week on-site (midweek).

Candidates must either live within realistic commuting distance of Kent or be genuinely willing to relocate. Unrealistic travel commitments will not be considered.

Salary & Package

£50,000-£55,000 depending on experience.

In addition, the company offers a strong benefits package and genuine long-term career progression opportunities within a stable, growing and technically advanced environment.

Why This Role?

  • Join a well-established global medical technology business
  • Work on technically complex, life-impacting products
  • Be part of a collaborative engineering team
  • Influence product architecture and integration standards
  • Excellent benefits package
  • Clear career development and progression pathways
