Job description

Engineer I - Electromechanical Integration

This is a hands on builder role for someone early in their engineering career, working under senior engineers across electrical, mechanical and software tasks. The work centers on making and testing physical prototypes: simple circuit boards, soldering and rework, firmware for test rigs, and fixtures made with laser cutters and 3D printers. A strong candidate brings a relevant engineering degree plus real bench time with scopes, meters and power supplies, and shows care in recording and organizing measurements.

How it fits the AI era

Much of the routine drafting, layout and data logging in this kind of work can be sped up with software tools, so the engineer can spend more time on judgment calls. What stays human is the physical craft: soldering, debugging a noisy board, and deciding whether a sensor reading is real or an artifact. Careful bench characterization and clean documentation remain the core of the job.

How it builds AI experience

The role offers grounding in generating reliable measurement data, which is the raw material for any data driven diagnostics work. Building that base means learning to design test setups, control instruments, and keep data organized and traceable. Experience with low noise analog measurement or signal processing would strengthen a candidate for the health data side of the company.

Worth showing

• PCB design and layout


• SMD soldering and rework


• Oscilloscope bench testing


• 3D printing and laser cutting
