Principal Sustainability Engineer | Hampshire | Permanent | up to £70,000 If you’re the an engineer who sees sustainability benefiting internal systems - not just a scoreboard of emissions - this one’s worth a look. PT Renewables is partnered with a global manufacturer in the medical devices world - think highly regulated, engineering-led, quality-first. Operating in 100+ countries, sustainability isn’t a side topic here, it’s a valuable part of operations, backed by investment, deadlines, and leadership attention. This role sits at the intersection of science, sustainability and technical innovation, helping drive decarbonisation, circular thinking, eco-design, and operational impact reduction across a global footprint. The Role You’ll be the go-to technical expert on sustainability engineering and design. You'll lead on research, feasibility and delivery of changes that cut carbon, reduce waste, rethink materials and improve environmental performance - all while still hitting cost, quality and compliance requirements. In practice, that means: • Leading the global decarbonisation programme, • Acting as the SME on waste, plastics, water, and eco-design, • Driving and validating Life Cycle Assessments and GHG reporting, • Translating global standards, regulations and tech trends into actionable programmes, • Running technical research, design changes, ECO processes and risk management, • Developing policies, training, and internal capability around sustainable product & process engineering, • Influencing decision-makers across engineering, ops, quality, procurement and supply chain About You This suits someone from both a consultancy or in-house background, but someone who enjoys complexity. Someone who can zoom from GHG methodologies, manufacturing processes, regulatory compliance, business cases, without dropping the thread. We’re looking for: • Solid experience implementing LCAs, decarb plans or major sustainability initiatives in a manufacturing or regulated environment, • Strong analytical and computational capability, • A credible engineering or scientific background with sustainability Package • Base salary up to £70,000, • Generous bonus opportunities, • 25 days holiday + enhanced pension, • Wellness support & benefits, • Training & career development, • A genuinely inclusive culture that values doing things properly (not greenwashing) If this sounds like you, and you want to join a global business who improve people's lives daily, apply now, we'd love to hear from you.
