Senior Engineer in Aberdeen

Claxton combines decades of industry experience, proprietary technology, and exceptional service quality to cut through offshore installation and decommissioning complexity. Globally, we partner with operators and key contractors in conventional energy, decommissioning, and offshore wind, delivering certainty when it matters. Our expert teams anticipate challenges, deliver innovative high-performance solutions, and provide responsive, transparent support at every stage — ensuring seamless project execution and enduring value, throughout the asset lifecycle and across the energy transition.

Claxton is currently looking to hire a Senior Engineer to join the team on a full-time, permanent basis. Ideally based at our facility in Aberdeen however location is flexible. The Senior Engineer contributes to the design, development and delivery of mechanical systems and products, from concept and analysis through to workshop build, testing, commissioning, and offshore execution. The role combines technical execution, design assurance, commercial awareness, and hands‑on involvement, supporting bids, leading engineering scopes, and mentoring junior engineers.

This position requires broad engineering capability across structural design, lifting and rigging interfaces, hydraulic and electro‑hydraulic control systems, drive trains (gears, gearboxes, motors, leadscrews) and mechanical motion mechanisms. The engineer will apply Claxton technologies to create practical, fit‑for‑purpose solutions that meet functional, safety and schedule requirements while maintaining an appropriate level of engineering detail.

The role operates in a fast‑paced environment, balancing multiple tasks and priorities while working collaboratively across disciplines. Strong communication skills and the flexibility to support workshop activities and offshore operations (as required) are essential, alongside a commitment to professional development and maintaining high engineering standards.
