Careers

We’re building something new in San Diego.

Our first product, the Stentrode, was an implantable brain-computer interface placed in people through their blood vessels. Our vision is for endovascular BCI to become a first-line therapy for people who can’t move their arms due to motor impairment.

Now we’re taking all those lessons and applying them to a new BCI hardware architecture that we believe will be the frontier.

We are working on three problems no one in this field has solved:

• Reaching all regions of the brain through a catheter, not a hole in the skull.
• Covering multiple brain regions at once, with high-density coverage that can scale.
• Putting active electronics on the brain itself.

To achieve this, we are looking for ambitious and technical people who want to work on:

• Digitizing at the electrode: our next system puts chips on the recording head and runs a digital lead to the implant body.
• Lead attach and overmolding between a thin-film array and that lead, built to flex for years inside the body.
• Thousands of channels on a tight power budget.
• Wireless power and telemetry through tissue.
• Films and encapsulation that last decades.
• An in-house ASIC team: test our first tape-out, then design the second chip.

The new Soho office is Synchron's cognition lab, where neural signals become models of human thought.

ML engineers, data engineers, software engineers, neuroscientists, and HCI researchers work on real-time neural data pipelines, closed-loop neurofeedback, model serving, Apple-native software, and one of the most interesting open questions in AI: whether scaling laws apply to brain data.

The environment is deliberately academic, with weekly research seminars and direct patient interaction.
