Senior Product Design Engineer

Location: Battersea, London / Hybrid — 3 days in the office

We are looking for a Senior Product Design Engineer to join our UK AD team, building a new generation of innovative products for our Shark Floorcare range. We thrive on designing great products that delight our customers. Working as part of our London Design Office, you will bring technical substance and inspiration to our creative efforts to deliver credible solutions to the market.

What You'll Do

• Take a lead role — independently and within teams — to solve technical challenges across the product development lifecycle
• Mentor more junior team members, with the opportunity to move into line management if desired
• Help establish user, design, and functional requirements for projects, then deliver robust solutions and validate through testing
• Own designs end to end, from conception through CAD execution, prototyping, and verification, consistently working at pace and developing the team to do the same
• Continuously evaluate and improve designs for cost efficiency, manufacturing performance, quality, and consumer value
• Apply sound engineering and product design standards to deliver real, manufacturable solutions
• Leverage deep knowledge of high-volume manufacturing processes and materials to optimise designs
• Collaborate seamlessly with Product Development teams across the US, UK, and China, as well as cross-functional and executive stakeholders

What You'll Bring

• 5+ years of proven experience in a mechanical or electro-mechanical engineering environment
• Strong understanding of mechanical systems in high-voltage environments, including material selection, heat dissipation, vibration control, and structural integrity
• Working knowledge of electromechanical systems — how mechanical components interact with electrical systems, including insulating materials, creepage and clearance distances, and thermal management
• Proficiency in SolidWorks (preferred) or Creo
• Extensive injection moulding experience and understanding of materials suited to high-voltage applications, including PPS and PAGF
• Expertise in managing electrical safety risks — dielectric, hi-pot, arcing, and related considerations
• Experience with FMEA, DFMEA, and HAZOP for risk assessment in high-voltage systems
• Understanding of IP ratings, dielectric strength testing, thermal runaway testing, and partial discharge testing
• Ability to design, build, and test mechanical prototypes in controlled environments
• Familiarity with thermal cycling, humidity, vibration, and impact testing for product reliability
• Proficiency in 2D drawings and assemblies, BOM management, and working GD&T knowledge
