Lead the Cultural Shift. Protect Our People. Shape the Future.
At Mars, safety is not a priority — it is a value. And we firmly believe that every accident is preventable.
We are looking for an inspiring Health, Safety & Environment Manager to join our Plymouth leadership team and lead a step-change in how safety and environmental excellence are embedded into our culture. This is not just a technical HSE role - it is a people leadership role focused on influencing mindsets, driving ownership, and ensuring safety is lived every day by every Associate.
As a key member of the Site Leadership Team, you will shape and deliver the site’s HSE strategy, champion Mars Supply Excellence (MSE) Safety Pillar deployment, and build a culture where speaking up, accountability, and proactive risk management are the norm.
Key Responsibilities:
- Cultural Leadership & Engagement: Lead a visible cultural shift aligned with the belief that every accident is preventable. Coach and challenge leaders at all levels to role model the right safety behaviours. Create an engaging HSE culture that energises Associates and strengthens accountability. Partner with operations, engineering and technical teams to embed safety into daily routines.
- Strategy & Governance: Develop and deploy the site HSE strategy and roadmap aligned with corporate and regulatory standards. Own and continuously improve the site's Integrated Occupational Health, Safety & Environment Management System. Maintain compliance with ISO45001 and ISO14001:2015. Lead the Mars Supply Excellence Safety Pillar at the site level.
- Risk Management & Assurance: Define, coordinate and maintain HSE risk assessments and emergency procedures. Ensure robust serious incident investigations and sustainable corrective actions. Lead site audit programmes and ensure timely closure of actions. Act as primary contact for external advisory bodies, regulators, and insurers.
- Capability Building & Sustainability: Deliver training and coaching that strengthens HSE knowledge and ownership across the site. Analyse and communicate HSE data and trends to drive proactive improvement. Drive continuous improvement initiatives that enhance safety and environmental performance. Lead site security policy and asset conservation improvements.
What are we looking for?
- A People-First Leader: Proven ability to inspire, coach and influence in a manufacturing environment. Strong communication skills with the confidence to challenge constructively. Collaborative approach - able to work through others and build strong relationships at all levels. Demonstrated ability to drive behavioural change, not just process compliance.
- Technical Expertise: Degree, HND or HNC in Science, Mechanical or Electrical Engineering (or equivalent). NEBOSH Certificate/Diploma (essential); IEMA or MSc/PGC in Occupational Health & Safety desirable. Strong knowledge of UK and European HSE legislation. Experience maintaining or leading safety/environmental management systems in manufacturing.
- Results-Driven & Strategic: Logical, independent thinker who can prioritise effectively. Track record of delivering results through teams. Comfortable balancing strategic direction with operational execution.
