About Synchron

Synchron’s vision is to build non-surgical brain–computer interfaces at global scale that protect the fundamental human rights of freedom of expression and autonomy. Our first mission is to develop motor decoders that restore the ability of 15 million people with paralysis to interact with the digital world. Our second mission is to develop whole-brain cognitive decoders that enable hundreds of millions of people with cognitive decline to preserve and expand their agency as cognition changes over time.

In pursuing these goals, we aim not only to help humans flourish, but also to drive fundamental discoveries in human intelligence. Our team operates at the intersection of healthcare and technology, translating breakthrough research into real-world, safety-critical systems.

About the Role

We are seeking a R&D Electrical Engineer to own the electrical and electronic hardware design of Synchron’s implantable devices. This individual will serve as the engineering authority for the implant’s electrical architecture – spanning neural front-end acquisition, mixed-signal ASIC integration, power management, RF telemetry, and PCB/flex-circuit design – with accountability from concept through design verification. This is a hands‑on, technically deep role with significant cross‑functional visibility.

The successful candidate must be equally comfortable reviewing schematic details and defining system‑level electrical architecture as the program moves through typical development phases.

• Own the end-to-end electrical architecture of the implant, including neural acquisition front end, mixed-signal processing, power regulation, and RF telemetry subsystems
• Lead schematic design, component selection, and circuit simulation for ultra‑low‑power implantable electronics
• Define electrical interface specifications and performance budgets across the implant system (power, noise, bandwidth, data throughput)
• Drive ASIC integration and co‑design with silicon partners, defining specifications, test plans, and bring‑up procedures
• Lead design of miniaturized, high‑density PCB and flex‑rigid circuit assemblies suitable for chronic implantation
• Manage layout reviews, signal integrity analysis, and design‑for‑manufacturing constraints at implant scale
• Coordinate with mechanical engineering on board‑level integration within hermetically sealed enclosures

• Architect power delivery and energy harvesting/storage strategies for long‑duration implant operation
• Design and optimize wireless communication links (custom RF, BLE, or inductive) under biological tissue constraints
• Establish power budgets and duty‑cycling strategies that balance neural data throughput against implant longevity

• Define and execute electrical verification and validation test plans aligned with design control requirements
• Lead bench‑level characterization, environmental testing, and EMC/EMI assessment of implant electronics
• Own failure analysis and root‑cause investigation for electrical anomalies across prototype and production builds
• Establish design‑for‑reliability practices including derating analysis, accelerated life testing, and worst‑case circuit analysis

• Serve as electrical engineering lead within the design controls framework (IEC 60601, IEC 62304)
• Author and maintain electrical design inputs, risk analyses (per ISO 14971), and verification/validation protocols
• Support regulatory submissions with electrical test reports, design rationale, and traceability documentation

• Partner closely with firmware, mechanical, and systems engineers to co‑optimize the implant across all domains
• Collaborate with the wider R&D team on neural interface electrical requirements and signal quality
