The company:
We are a profitable, fast-scaling defence-tech startup - operating on the extreme edge of innovation in the evolving domain of Unmanned Systems / Drones.
Our world-class team of Engineers are delivering solutions deemed impossible by many, for some of the most complex and challenging problems in the Drones / UAS space.
With strong revenue growth, a loyal customer base, and an ambitious scaling plan, we are entering an exciting new phase of growth — and this is a rare opportunity to join at the moment it matters most.
Why this role exists:
We have multiple products in active service and demand is strong and increasing fast. Our current Engineering team is small, stretched, passionate, motivated and rapidly growing. We need an experienced Principal Electronic Design Engineer who can take full ownership of detailed design work across our product lines and start delivering from week one. Through the team you will have responsibility for directing, tasking, nurturing and coaching for excellence, delivery at pace and precision in their output.
This is a hands-on design role where the distance between your desk and the development areas is measured in metres. You will contribute to the design of product, facilitate the procurement / manufacture / selection of parts and then work with a wider team to build the prototype. If you have spent your career wishing you were closer to the hardware whilst guiding and influencing others, this is that job.
What you will do:
- Have accountability for the technical delivery of electronic engineering expertise to projects, subsystems, and/or technology developments.
- Lead, guide, direct electronic design activities across applicable projects, which will include leading, coaching, and motivating a growing team of electronic design engineers.
- Advocate and lead the adoption of best practice electronic engineering to improve the delivery of the engineering function to time, cost, quality and specification, whilst ensuring the appropriate level of effective technical governance is in place for safety, compliance, quality and reliability.
- Devise and distribute technical work packages, often across multiple cross functional teams, guiding the project toward a successful passage through project milestones through to completion and volume production.
- Ensure electronic engineering of product development meets stakeholder and product requirements, and is compliant with relevant regulations, directives and standards, by design.
- Develop Subject Matter Expertise in relevant areas of the electronic design of our product portfolio, towards recognition as a Principal Engineer and an expert in those areas.
- Drawing on your extensive experience, offer expert advice to other engineers, including supporting the training and development of engineers through formal and informal mentoring, effective professional development plans, and including where applicable professional registration to become highly effective mechanical design engineers as a part of a growing and vibrant talent pool.
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.
