Senior R&D Mechanical Engineer - Wearables & Skin Interface

Story Terrace Inc.; Greater London; On-site; GBP 85,000 - 120,000; Full time

Job summary

SAVA in the United Kingdom is seeking a Senior R&D Mechanical Engineer to own early-stage experimental work on our wearable sensor platform. You will set the experiment strategy, decide what to test and how, and translate complex data into engineering decisions that shape the product.

The role focuses on device adhesion, skin interface, wear performance, and lab test capability. You will mentor others and help scale our lab toward regulated medical device development.

Qualifications

• Masters or PhD in mechanical engineering or closely related field.
• 6+ years of hands-on experimental R&D, ideally including time in industry.
• Track record of leading technical workstreams from open question to clear outcome.
• Deep expertise in experimental design and statistics (DoE, ANOVA, regression, capability analysis).
• Strong experience with mechanical and materials testing - tensile, peel, shear, fatigue or similar.
• Confident designing test fixtures and prototypes (CAD, 3D printing, machining).
• Fluent data analysis in Python, MATLAB, Minitab, JMP or similar.
• Sound engineering judgement to make good calls with incomplete data and explain why.

Responsibilities

• Own adhesive and device-skin interface workstream end to end: material strategy, peel/shear/tack testing, wear-time studies and failure analysis.
• Set the experimental approach for early R&D - define DoE and screening strategies, and ensure conclusions are statistically sound.
• Design and build test rigs, fixtures and methods from quick prototypes to robust lab procedures.
• Lead selection, evaluation and qualification of new test equipment; author methods and SOPs.
• Drive early-stage concept work on new materials and mechanical designs from hypothesis to recommendation.
• Partner with biomaterials, sensor and electronics leads to translate findings into design decisions.
• Mentor junior engineers and scientists on experimental design, statistics and good lab practice.
• Communicate results and recommendations clearly to leadership.
• Shape the test strategy for design verification as we move toward a regulated medical device.
