Principal Sustainability Engineer

General Description

Principal Sustainability Engineer | Hampshire | Permanent | up to £70,000

While professional experience and qualifications are key for this role, make sure to check you have the preferable soft skills before applying if required.

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. xwzovoh

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.
