Overview
We're looking for an engineer who wants to take ownership of complex client projects and help solve some of the most challenging problems in surgery, medical devices, and therapeutic delivery.
COSA is a Cambridge-based anatomical engineering company that helps pharmaceutical, biotechnology, and medical device companies de-risk surgical procedures, therapeutic delivery systems, and medical technologies throughout development and clinical adoption.
We develop advanced anatomical models, surgical simulation platforms, and validation systems that enable our clients to better understand complex anatomy, evaluate new devices and therapies, train clinicians, and reduce technical and clinical risk before reaching patients.
Our work sits at the intersection of engineering, medicine, and translational research. By combining advanced medical imaging, computational modelling, additive manufacturing, materials engineering, and clinical expertise, we help tackle some of the most challenging problems in surgery and therapeutic delivery.
Who We're Looking For
We're looking for a proactive and adaptable engineer who enjoys solving difficult problems and taking ownership of their work.
The ideal candidate will have a background in Biomedical Engineering or Mechanical Engineering, although we're open to applicants from other technical disciplines who can demonstrate a strong aptitude for problem solving and learning new skills.
Experience in all of our technical domains is not expected. We care more about curiosity, initiative, critical thinking, quality of work, and the ability to learn quickly than deep expertise in a single area.
You will thrive if you enjoy working directly with clients, taking responsibility for delivering projects end-to-end, and finding creative solutions where no obvious answer exists.
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.
