Product Design Engineer; Mid-Weight​/Senior

POTR is a design‑led, sustainability‑driven brand reinventing plant care for modern living. From our origami‑inspired, self‑watering planters to developing the next generation of indoor growing, we combine clever engineering with bold aesthetics to help people grow h two RHS Chelsea Flower Show sustainability awards under our belt, we’re building a brand for the botanical world that sits at the intersection of design, tech, and interiors.

Location: Glasgow

Reports to: Head of Product Engineering / Engineering Lead

Job type: Full-time

Level: Mid-weight (~4-7 yrs experience) or Senior (~8+ yrs) – please specify level in application.

As a key member of our product development team, you will lead the design engineering of our next‑generation products, transforming how people grow  will partner closely with industrial designers, electronics/controls engineers, manufacturing & supply‑chain partners, and the company founders to bring innovative, sustainable, manufacturable products to market that align with POTR’s mission. You’ll champion engineering excellence, design for manufacture/assembly (DfM/DfA), cost and sustainability efficiency, and deliver products from concept through to production launch and post‑launch sustainment.

• Take a leading role in development projects from concept through prototyping, validation, tooling, manufacture and production launch.
• Work with industrial designers to translate aesthetic & user experience vision into engineered, manufacturable products - ensuring POTR's design language and sustainability ethos are met.
• Create detailed CAD models (solid & surfacing), assemblies, drawings, specifications, tolerancing, material selections appropriate for plastics, metals, composites, and multi‑material assemblies.
• Apply DfM/DfA principles, cost‑engineering, part count reduction, supplier/manufacturer collaboration to optimise for high‑volume, high‑quality manufacture and sustainable materials/processes.
• Prototype (rapid and functional), support test plans, validate and iterate on product performance (mechanical, structural, durability, lifecycle, ergonomics, aesthetics).
• Work with electronics/controls engineering (where applicable) to integrate mechanical, structural, thermal, fluidic, user‑interaction, and watertight irrigation systems.
• Partner with supply‑chain/manufacturing to select vendors, define tooling strategy, support injection moulding, metal fabrication, stamping, sheet‑metal, plastic bonded assemblies, composite parts and sourcing a variety of different sustainable materials.
• Maintain and document engineering change control, BOMs, manufacturing specifications, quality and regulatory requirements (safety, CE/UKCA, RoHS, REACH, etc as relevant).
• Drive design reviews, milestone gate‑processes, risk‑management, issue‑resolution and continuous improvement.
• Mentor junior engineers (for Senior level) and foster best‑practice engineering culture within the team.
• Help define and embed sustainable engineering practices: material reuse/recycling, carbon footprint, packaging minimisation, end‑of‑life considerations.

• Bachelor’s degree or higher in Mechanical Engineering, Product Design Engineering, Mechatronics or related discipline.
• For Mid‑weight: ~3-5 years’ experience in product design/design engineering of consumer‑facing/electromechanical products. For Senior: ~5+ years.
• Proven track record of taking products from concept to manufacture, ideally in consumer, lifestyle or home‑tech products.
• Strong CAD competency (Fusion used internally but equivalent with Solid Works, Creo, NX, Fusion etc also accepted) including surfacing, solid modelling, assemblies and detailed drawing output.
• Deep understanding of manufacturing processes (injection moulding, sheet‑metal, stamping, die‑casting, extrusion, composites, tooling, assembly, finishing), and design for manufacture & assembly.
• Strong prototyping, testing and validation experience: functional prototypes, test rigs, failure/root‑cause analysis and resolution.
• Excellent collaboration across cross‑functional teams (industrial design, electronics, firmware, supply‑chain, manufacturing, QA, marketing).
