Senior Linux/HPC Project Engineer & Team Lead
Hybrid Working with Offices near Haywards Heath, West Sussex
Package: Salary Circa £65k DOE + Benefits + Bonus

Join an international, next-generation HPC data centre organisation as a Senior HPC Engineer and Eastern Hemisphere Technical Project Team member. This is a varied, high-impact position with broad responsibility - blending Level 3 technical support, technical project delivery, leadership, and cross-team collaboration.

You'll take a lead role on technical projects: scouting and evaluating new technology, running proof-of-concept initiatives, implementing solutions, and presenting outcomes to a wide audience. With significant autonomy, you'll proactively identify and drive technological advancements and best practices, shaping both infrastructure and operations.

The current team is technically strong but needs a hands-on technical leader/architect to bridge the people-management gap. You don't need to manage a large team, but you do need to run meetings, gather updates, confidently communicate with the business, and deputise for leadership - whether you already have people leadership experience or are ready to step up.

Responsbilities

• Lead and deliver end-to-end technical projects: discovery, evaluation, proof of concept, implementation, documentation, and presenting outcomes to a wide audience.
• Provide 3rd line ('last line') escalation support for the most complex technical issues
• Work extensively on technical projects and proof of concepts, with a focus on next-generation data centre technologies (e.g. oil immersion cooling).
• Integrate new tools and technologies into business functions and continuously look to improve how existing systems operate.
• Act as a senior technical engineer/architect within an HPC and next-gen data centre environment.
• Serve as a strong deputy to senior leadership, stepping up to run meetings, gather updates, and communicate clearly with senior stakeholders when required.
• Present confidently to various audiences, propose new technologies, and ensure communication is clear and professional at all times.
• Promote collaboration, pull together a technically strong but introverted team, and support mentoring as needed.
• Be proactive and autonomous: identify improvements and solutions independently, and bring them forward for team consideration.
• Potential travel to support wider regional projects, including new data centre builds (especially within Asia-Pacific), as required.
• As/when available, join a 24/7 on-call rota (approximately 10% on-call allowance), once settled into the role and as dictated by team needs.

Requirements

• Strong technical background with advanced Linux engineering/architect-level experience; direct HPC background is highly desirable but not mandatory if you have high-level Linux and architectural skills and learn quickly.
• Proven ability to run technical projects end-to-end: from discovery through evaluation, proof of concept, implementation, documentation, and presentation.
• Experience integrating new technologies into business environments and improving existing systems.
• Ability to act as a hands-on senior technical engineer while also stepping up as deputy when needed.
• Comfortable running meetings, gathering updates, and communicating clearly and confidently with both technical colleagues and senior business stakeholders.
• Strong presentation skills; capable of proposing and explaining new technologies to different audiences.
• Team-oriented mindset-able to mentor, encourage collaboration, and help pull together a group of technically excellent but introverted engineers.
• Displays clear leadership potential or established leadership experience, with a willingness to develop people and stakeholder management skills.
• Proactive and autonomous: able to identify challenges and introduce improvements without waiting for specific instruction.
• Mature and experienced enough to fit as a senior technical leader
• Excellent communication in English, with experience engaging UK-based stakeholders.
