The Opportunity
We are currently recruiting for a Service Supervisor to join an established and highly regarded fire and security systems business, working on a static site in Canary Wharf, London.

We're particularly interested in engineers with strong technical experience who have already had some exposure to supervising or leading others. ETS3 experience would be highly advantageous and is particularly sought after.
Key Responsibilities

- Provide technical guidance and support to engineers, both on site and over the phone.
- Remain hands-on with engineering activities, including fault finding, troubleshooting, and resolving complex system issues.
- Plan and coordinate engineering works, ensuring resources, materials, and personnel are effectively organized.
- Monitor service delivery against agreed KPIs, customer requirements, and company standards.
- Act as an effective link between the site-based engineering team and management.
- Mentor and support engineers, helping to develop technical capability and best working practices.
- Assist with the induction and training of new engineers.
- Lead by example, promoting high standards of workmanship, customer service, and professionalism.
- Carry out regular health and safety checks and support the implementation of corrective actions where required.
- Identify opportunities to improve engineering processes, efficiency, and service delivery.
- Maintain strong working relationships with customers, colleagues, and other stakeholders.
- Ensure all engineering activities are completed safely, professionally, and in accordance with relevant standards and procedures.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
