Hardware Product Designer in London

About SAVA

All the health information we need is within us. Just below the skin. SAVA is redefining the way people interact with their health by developing the most advanced biosensing technology science has to offer, capable of accessing bodily information in a painless, real-time and affordable way.

The Role

Sava Technologies is hiring a Product Design Lead to work directly with the founders, engineering and manufacturing teams to define the physical expression of the product. This is a hands‑on role for someone who cares about how products are made, how they feel and how they integrate into people’s lives. You will play a key role in our last‑mile design choices: materials, finishes, assembly, usability, cost and manufacturing tolerance.

Here at Sava, we’re building a new kind of wearable for metabolic health. Yes, the engineering and manufacturing aspects aren’t straightforward, but that shouldn’t mean the final product feels the same way. Most medical devices are treated as purely functional objects. We believe that’s a mistake. If something becomes part of someone’s daily life, design matters just as much as performance.

What You’ll Do

• Drive the material and finish direction end-to-end by prototyping ideas, testing with the manufacturing and engineering team and validating samples.
• Specify premium materials, textures and coatings that feel intentional on skin and survive several days of continuous wear.
• Choose finishes that enhance trust and durability.
• Ensure the attachment mechanism and form factor feel intuitive and effortless for those wearing the device continuously.
• Work hands‑on with our manufacturing team to refine tooling, validate tolerances and iterate through physical samples.
• Shape product architecture decisions about form factor, sensor integration and material interaction.
• Own the packaging and unboxing experience from how the product arrives to how it feels in their hands.
• Translate your understanding of wearability, user‑behaviour and ergonomics into sketches, CAD models and design ideas that improve usability.

What We’re Looking For

• 4+ years of industrial design experience with shipped consumer products (wearables, consumer electronics or design‑forward hardware).
• Strong CMF expertise (colour, material, finish specialisation) and the ability to clearly articulate design decisions.
• Experience designing for wearables, medical devices or consumer electronics.
• Comfortable working directly with manufacturing partners and suppliers. You iterate on samples, give feedback and align design and production.
• Strong CAD capability and ability to iterate rapidly while balancing aesthetics, usability and manufacturability.
• Strong visual taste and design intuition and comfort operating in a startup environment.

Bonus Points For

• Experience with skin‑contact wearables or continuous‑wear medical devices or familiarity with regulated medical device environments.
• Prior experience at design studios like LAYER, Native Design, PDD or similar.
• Design roles at consumer product companies.

Why Sava

This is a high‑ownership, high‑responsibility role in a company that’s building something complex, meaningful, and fast. The expectations are high, the learning curve is steep, and the work is often messy, but the impact is real. You can directly shape how a novel medical device reaches people. We don’t have room for egos or passengers. What we do have is a team of thoughtful, driven, and mission‑aligned people committed to building something better and doing it with urgency and integrity.
