Job description

About FCDS

FC Design Services is an electronics design and contract manufacturing company based in Mason, Ohio. We design custom electronics for our customers and assemble everything from prototypes to high volume on our SMT focused assembly line. We're a small, fast-moving team, and no two projects look alike.

The Role

We're looking for a senior hardware engineer who can take a client's idea from a rough concept to a working board and who enjoys switching between very different projects. You'll own schematic capture and PCB layout, everything from basic mixed signal control boards to RF and high-speed designs. Lead client projects from kickoff through prototype and into production.

What You'll Do

• Lead client hardware projects end-to-end, from requirements and architecture through prototype bring-up and release to production.
• Create schematics and multilayer PCB layouts for mixed-signal, RF, and high-speed digital designs.
• Design controlled-impedance and high-speed interfaces, including stackup planning and signal integrity.
• Serve as the primary technical contact for clients: scope work, run design reviews, and explain tradeoffs.
• Bring up and debug boards in the lab with oscilloscopes, spectrum and network analyzers, and other test equipment.
• Work with our manufacturing team on DFM/DFT so designs build cleanly the first time.
• Manage several projects at once and adapt as priorities shift.

What You Bring

• 5–8 years of hands‑on hardware design experience.
• A BSEE, a BSCpE, or equivalent experience.
• Strong schematic and PCB layout skills in Altium Designer. Bonus points for KiCad experience.
• Hands‑on RF and/or high-speed layout experience, including impedance control, grounding, and signal integrity.
• A track record of owning designs from concept through production.
• Comfort working directly with clients and explaining technical decisions clearly.
• Self‑direction and a genuine enjoyment of variety.

Nice to Have

• Microwave or mmWave PCB design experience (20+ GHz).
• Experience with STM32, Nordic, ESP32, or similar microcontroller platforms.
• Background in defense, aerospace, or medical products, and familiarity with IPC standards.
• Prior experience at a design consultancy or product development firm.

Location & Schedule

This is a hybrid role with 2–3 days per week on-site at our Mason, Ohio shop.

Candidates must live within commuting distance of Cincinnati or Dayton.
