Next Generation Wrist Wearable
We are expanding our wearable platform with a new enclosure designed for demanding operational environments. We are looking for someone who can combine a rugged, tactical aesthetic with wearer comfort, sensing precision, manufacturability, and robust engineering.
Building on our existing physiological monitoring technology, you will work alongside our multidisciplinary engineering team to take the enclosure and associated mechanical components from initial concept and prototyping through verification and final production.
Key Responsibilities
- Help plan development and translate user needs into clear technical requirements, measurable design criteria, and test plans, identifying applicable standards and acceptance criteria.
- Design the enclosure, strap, seals, sensor windows, fixings, and internal supports, integrating the electronics, sensors, screen, and battery.
- Address reliable sensor contact, comfortable and secure fit across different wrist sizes, durability, and water resistance.
- Select materials and manufacturing processes. Deliver CAD models, engineering drawings, prototypes, and production documentation, with appropriate tolerances and assembly methods.
- Ensure the design meets applicable mechanical, material, and environmental standards. Coordinate and support verification and validation testing to demonstrate compliance and confirm agreed technical requirements are met, working with engineering and regulatory specialists.
- Identify, select, and manage suppliers. Oversee tooling, manufacture, assembly, and production quality, delivering initial production batches and preparing for larger scale manufacture within agreed cost and schedule targets.
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.
