Senior Electrical Engineer – Wearable Audio Devices (Early-Stage Startup)

We’re working with an early-stage, venture-backed startup developing breakthrough wearable audio technology. As they move from early prototypes toward production, they are now looking for a Senior Electrical Engineer to join the founding team and take a leading role in building next-generation audio wearable products.

About the Role

This is a high-impact, hands‑on engineering role where you will work directly with the founders to design, develop, and scale cutting‑edge wearable audio hardware. You’ll have significant ownership from day one and will be expected to operate independently in a fast-moving, highly technical environment.

You will be responsible for taking products from early concept through to production, with a strong focus on high-volume consumer wearable audio devices, ensuring performance, reliability, manufacturability, and cost efficiency at scale.

What You’ll Be Doing
  • Lead electrical design and development of wearable audio hardware systems end-to-end
  • Work directly with founders to define technical direction and product architecture
  • Own schematic capture, PCB design, prototyping, and validation
  • Drive hardware from early-stage prototypes through to mass production
  • Collaborate with firmware, mechanical, and acoustics partners to deliver integrated products
  • Ensure robust design for manufacturability (DFM) and design for test (DFT)
  • Troubleshoot complex hardware issues across development and production phases

    Engage with external suppliers and manufacturing partners as required
What We’re Looking For
  • Strong experience in consumer electronics or wearable audio hardware products
  • Proven track record delivering products into high-volume manufacturing
  • Deep understanding of analog and digital circuit design
  • Experience with compact, low-power embedded systems
  • Exposure to Bluetooth/audio systems highly desirable
  • Comfortable working independently in an early-stage startup environment
  • Strong execution mindset with the ability to take ownership without heavy structure
  • Thrives in ambiguity and fast-paced product development cycles
Why Join?
  • Work directly with the founders and have real influence over product direction
  • Join a small, elite team building category-defining audio technology
  • High ownership, high impact role with minimal bureaucracy
  • Opportunity to take a product from concept to global scale
  • Onsite collaboration in Boston with a deeply technical founding team
