Principal Mechanical Engineer – Concept Innovation & Advanced R&D
Some engineers enjoy managing people.
Others enjoy solving problems that have never been solved before.
This opportunity is for the second type.
We are working with a highly advanced engineering and technology business that develops ultra-precision equipment used in demanding technical applications around the world. Their products push the boundaries of mechanical performance, accuracy and reliability.
They are looking for an exceptional mechanical engineer whose passion lies in creating, innovating and solving complex technical challenges. This is not a people management role.
It is a role for someone who wants to spend their time thinking deeply about engineering problems, developing elegant solutions and taking ideas from a blank sheet of paper through to a working product.
The Role
You will become one of the key technical minds within a multidisciplinary R&D team, helping to shape the next generation of sophisticated electro-mechanical systems. You will have the freedom to challenge assumptions, explore new concepts and drive technical innovation throughout the entire product development cycle. Expect to work on projects where the answers are not already known.
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.

Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You'll Be Doing
- Developing original concepts for highly complex mechanical systems.
- Solving difficult engineering problems where precision and performance are critical.
- Taking ownership of designs from initial idea through to production.
- Using analysis, simulation and experimentation to validate solutions.
- Working alongside electronics, software and systems engineers to develop integrated products.
- Influencing technical direction and engineering standards.
- Contributing your expertise during design reviews and technical discussions.
- Sharing knowledge with colleagues without the expectation of formal line management responsibilities.
We're Looking For Someone Who...
- Loves engineering for the sake of engineering.
- Enjoys understanding how things work at a fundamental level.
- Naturally questions accepted solutions and looks for better ones.
- Thrives on technically difficult challenges.
- Is motivated more by solving problems than by managing teams.
- Wants to build products rather than spend their time in meetings.
Technical Experience
You'll probably have experience in a number of these areas:
- Precision engineering or high-performance mechanical systems.
- Electro-mechanical product development.
- Motion systems, drives or precision mechanisms.
- Full product lifecycle development.
- Finite Element Analysis (FEA) including structural, stiffness or vibration analysis.
- Advanced CAD packages such as SolidWorks, NX, Creo or CATIA.
- Materials selection and manufacturing processes.
- Systems engineering principles.
- Engineering analysis tools such as MATLAB or similar.
