Senior Mechatronics Engineer

Sharper Sense is an early‑stage neurotechnology company (spun out of Columbia and Cornell; backed by Joyance Partners, SOSV, and Comcast NBC). We develop wearable, noninvasive neuromodulation patches that use electrical stimulation to optimise brain state, cognition, and sensory processing. Following successful pilot clinical studies, we are hiring to support the design and testing of the skin adhesives used in our self‑contained patch hardware.

• Job Title: Electrical / Software / Mechanical Engineering (Mechatronics)
• Location: In‑person at our offices in Newark, NJ + remote when possible (hybrid).
• Role: Design, build, test, and support the electrical, software and mechanical systems behind our wearable neurostimulation products from prototype through production.
• Required Skills: Hands‑on mechatronics experience across electronics, embedded systems, mechanical design, fabrication, 3D printing, testing, manufacturing, and product support.
• Type: Option for full‑time, part‑time, or project‑based work depending on availability and fit.
• Pay: $60K–$100K per year + stock options + benefits.

We are seeking a Mechatronics Engineer to join our team and support development, from prototype to production, of our self‑contained wearable neurostimulation patch. This role can flex from junior to senior depending on capability, but the best fit is someone who can bridge electrical engineering, software engineering, mechanical engineering, fabrication, manufacturing, and product support. You will work closely with our existing team that includes mechatronics, biomedical, and neural engineers and scientists to improve whole‑system performance, accelerate time to market, reduce risk and cost, and help turn working prototypes into reliable products.

• Design, prototype, test, and improve integrated electrical, software, and mechanical systems for wearable neurostimulation products.
• Support circuit design, PCB bring‑up, embedded firmware, enclosure design, flex‑board integration, patch construction, and system‑level troubleshooting.
• Build and modify prototypes using practical fabrication methods such as soldering, rework, bench testing, CAD, 3D printing, adhesives, fixtures, and vendor‑manufactured mockups.
• Translate prototype learnings into manufacturable designs, including DFM feedback, assembly process development, test planning, quality checks, and supplier communication.
• Help evaluate and select components, materials, batteries, adhesives, hydrogels, films, coatings, PCBAs, and manufacturing partners based on performance, cost, lead time, reliability, and supply‑chain risk.
• Test products on bench and in human‑use scenarios for stimulation performance, battery life, comfort, adhesion, sweat exposure, safety, reliability, usability, and manufacturing consistency.
• Improve the product based on customer, clinical, demo, manufacturing, and internal team feedback across the full product lifecycle.
• Document design decisions, test results, manufacturing processes, change logs, build instructions, and support learnings clearly enough for others to reproduce and improve the work.
• Collaborate across disciplines with hardware, software, mechanical, biomedical, neuroscience, business, regulatory, clinical, and manufacturing stakeholders.

• Degree preferred in electrical engineering, mechanical engineering, computer engineering, computer science, mechatronics, robotics, product design, manufacturing engineering, or related field. Equivalent applied experience will be weighed heavily.
• 5+ years of relevant hands‑on experience in product design, development, manufacturing, fabrication, test, support, and systems engineering.
• Experience shipping and supporting at least one product through a meaningful portion of its full lifecycle, from concept or prototype through manufacturing, release, customer feedback, iteration, and support.
• Demonstrated ability to work across all three: electrical engineering, software/embedded systems, and mechanical engineering with interest in biomedical and neural.
• Practical experience with PCBAs, microcontrollers, embedded firmware, sensors,…
