Job Description
We have an exciting opportunity for a Senior Condition Monitoring Diagnostic Engineer to join the Aberdeen team, reporting to the Condition Monitoring Manager. In this role, you will be responsible for the technical analysis and reporting of machinery data, including vibration and other condition monitoring techniques. You will generate high-quality reports, provide actionable recommendations, and contribute to continuous improvement initiatives. The role involves peer reviewing technical documents, engaging with customers both remotely and on-site (including offshore visits), and supporting clients with equipment troubleshooting such as balancing and orbit analysis. A strong team player, you will also be confident working independently on customer sites, mentoring clients in basic CM practices, and demonstrating the value of implemented recommendations. This position operates within the framework of the John Crane Integrated Management System (IMS), ensuring all work is delivered to the highest standards.
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.
