Auricle | Founding Biomechanical Engineer (Neurotech Medical Device) | ONSITE (Mountain View, CA) | Full-time | https://auricle.com

Auricle is developing a next-generation neurostimulation implant to restore hearing and the ability to understand speech in the millions of people who no longer benefit from acoustic amplification with hearing aids but who aren't prepared to take on the risks of a cochlear implant.

We're searching for a full-time engineer to join our founding team. Our device and prototypes are partly mechanical, electrical and software so we'll need someone who can wear multiple hats but is comfortable primarily in the mechanical domain as we execute on early clinical and pre-clinical studies.

Experience with rapid prototyping using 3D printing, CAD and bench models is a must. Experience of medical device development within a quality management system and developing pre-clinical models is highly valued. Bonus points for electrical engineering experience, programming experience (Python/Matlab) and a passion for auditory science. More than anything, we're looking for someone who will be highly motivated to help bring a complex but life changing device to patients.

We're a small team formed out of Stanford and backed by YC (W21), based out of Fogarty Innovation in Mountain View. The role is primarily in-person with very occasional travel to study sites and with some flexibility for hybrid work from time to time.

We're excited to hear from you! Email is hidden

Purplefish | https://purplefish.com/careers | Member of Technical Staff | Full-Time | ONSITE | New York, NY, USA | NextJS, Typescript, Python | $150k-$225k + 0.5%-1%+

Purplefish is transforming the trillion-dollar talent industry with powerful AI agents that will fully automate most hiring processes end-to-end.

We are funded by 8VC, and Adam and I previously worked closely together to launch 145 companies at the venture studio Fractal Software out of a $650 million fund. Before that I was a staff software engineer at Lyft, and Adam was CRO at Wunderkind ($100m+ ARR). We've built a powerful voice agent, and are expanding into other parts of the sourcing-to-onboarding flow.

We're currently a team of 3 engineers in NYC (9 people total). We're working on really cool problems with multimodal AI agents (and some really not cool problems like ATS and HRIS integrations). I'm trying to build the engineering team that I would want to join, which to me means a high emphasis on agency, purpose, technical excellence, collaboration, learning and velocity. Recently A16Z mentioned us in the state of voice AI report: https://a16z.com/ai-voice-agents-2025-update/

We're building on LiveKit's agents framework and a host of other systems. We're looking for builders - people who are willing to learn and experiment and build fast.

If that's interesting, let's talk.
