Founding Electrical Engineer — Acoustic Sensor Lead

Laran; Los Angeles (CA); On-site; USD 130,000 - 180,000; Full time

Job summary

Soundryx, Inc. in Los Angeles seeks a Founding Electrical Engineer to design a custom PCB microphone array and power systems critical to the platform. You will own MCU/FPGA choices, drive ruggedized hardware, and collaborate with DSP/ML teams on HW/SW co-design for export-controlled projects.

The role emphasizes field-ready hardware, DFM/DFX, and early process establishment, with a strong emphasis on autonomy and multi-day operation in outdoor environments.

Qualifications

• 4–8 years in electrical/embedded hardware (startup or product‑ship preferred).
• Shipped boards with MCUs or FPGAs, high-speed digital, mixed‑signal, and power.
• Proven PCB design - fab - bring-up cycle ownership.
• Battery integration (Li‑ion/LiFePO4, charging, protections, fuel gauging).
• Environmental/ruggedization experience (IP67/68, potting, gasketing, coatings).
• Nice-to-have: beamforming algorithms implemented.

Responsibilities

• Lead design of a custom PCB microphone array (schematic, layout, bring-up; Altium/KiCad).
• Own embedded MCU/FPGA choices and real-time audio processing pathways.
• Drive DFM/DFA, vendor selection, EVT/DVT/PVT, and production test fixtures.
• Architect battery & power systems (PMICs, charging, protections) for multi-day autonomy.
• Engineer for the outdoors: sealing, thermal, vibration, corrosion, IP-rating minded.
• Collaborate with DSP/ML on HW/SW co-design; define clean ICDs/APIs for the stack.
• Establish early hardware processes (libraries, test plans, component risk, ECOs).
