Energy programmes move in phases, and we resource them with contract and interim specialists across nuclear, renewables and fusion, scaling teams up or down as design, construction, operations and maintenance demands shift.

Rullion specialises in interim and contractor recruitment across critical infrastructure, sourcing talent at every level of seniority for rail, nuclear, energy and utilities when you need it most.
An unexpected increase in workload is straining your team. A sudden surge in work can leave you short-staffed, and temporary recruitment fills the gap without adding long-term headcount.
Permanent headcount is not always the right option. Not every piece of work needs a permanent hire, so a temporary or contract worker offers a cost-effective, flexible solution that matches workforce demand.
You want to reduce the risk of a long-term hiring decision. Temporary workers can move into permanent roles if they prove to be the right fit, lowering the risk of a permanent hire.
Immediate access to specialist talent is critical. Temporary recruitment lets you bring in skilled professionals quickly, avoiding the delays of a permanent recruitment process.
Being specialists in contract and temporary recruitment for critical infrastructure means we understand what it takes to keep your projects resourced. From rail and nuclear to renewables and water utilties, we place interim professionals and contractors at every level of seniority, whether you are covering an absence, managing a workload spike, or resourcing a major programme.
Our temporary and contract recruitment covers every stage, from sourcing to compliance and payroll. Here is what you can expect when you bring in interim talent across critical infrastructure with Rullion.

Transport projects rarely run to a steady headcount, so we supply contract and temporary engineers and technicians across rail, rolling stock, and aerospace, keeping programmes resourced through demand peaks, planned shutdowns, and tight delivery windows.

Whether you’re hiring a single specialist or building an entire project team, our flexible workforce solutions are designed to help you attract, engage and retain the talent you need to deliver with confidence.
Contract recruitment engages professionals on a fixed-term or project basis, giving you specialist skills or short-term cover without the commitment of a permanent hire. It is often the default model for critical infrastructure organisations delivering major nuclear new build, rail construction and water infrastructure programmes.
Both sit under the broader umbrella of interim and contingent workforce solutions, and the right choice depends on the work. Contract roles are typically project-based with defined deliverables and a fixed duration, while temporary roles more often cover shorter-term needs such as sickness, absence or seasonal demand.
Yes, compliance sits at the centre of what we do. From IR35 status determinations through to identity verification and contractor onboarding, we cover the details, including managing umbrella company compliance with SafeRec. We also coordinate the sector-specific screening critical infrastructure demands, so the right people join your business with clearances already in place.
Whether you need a single interim specialist or a full project team, we scale our temporary recruitment services to match demand. For higher-volume or longer-term needs, our contingent workforce management and Statement of Work services may also be worth exploring.
It depends on the role and sector, but we move quickly. We maintain established networks across core critical infrastructure expertise, many of whom we know well and have placed before, so we can often reduce time-to-hire compared with starting a search from scratch.
We take our duty of care seriously. That means clear contracts, prompt and accurate payments, and ongoing communication throughout an assignment. Workers also have access to wellbeing support through Able Futures, in line with our Safe Rec commitment to health, safety and sustainability.
