Principal Mixed‑Signal Hardware Engineer (Scientific Instruments)
LECO, Portage, Michigan, United States, 49002
Principal Mixed‑Signal Hardware Engineer (Scientific Instruments)
Base pay range
$115,000.00/yr - $170,000.00/yr
Join LECO in St. Joseph, Michigan—an 80+ year, family‑owned innovator in world‑class laboratory instrumentation. We value long‑term stability, loyalty, trust, and shared purpose, and our products support scientists around the globe.
Schedule:
Monday–Friday, 8:00 a.m.–5:00 p.m., on‑site
A day in the life
You’ll start your morning reviewing your engineering notebook and latest test data from a precision measurement board. By midday, you’re collaborating with mechanical and software peers to refine a subsystem architecture for a next‑generation instrument. In the afternoon, you’ll implement design updates, run bench evaluations, and capture findings for design reviews—operating with a high degree of technical independence throughout.
Role overview
As a senior engineer, you will own the design of advanced electrical components and sub‑assemblies with minimal oversight. You will report to the Manager, Electronics Research & Engineering, or the Manager, RF Products.
What you’ll own
End‑to‑end design of electrical components and sub‑assemblies, from concept through release
Researching, building, and testing prototypes to validate performance
Diagnosing and resolving production issues in partnership with manufacturing
Authoring and maintaining design artifacts (schematics, BOMs, specifications) and keeping a logbook
Preparing documentation packages for formal design reviews
Contributing within cross‑disciplinary teams while accounting for system‑level tradeoffs
Investigating emerging technologies to drive product innovation
Leading specialty electrical design efforts independently
What you bring
Depth across a broad spectrum of electrical engineering topics, including:
Mixed‑signal design (ADC/DAC) for precision measurement systems
Microcontroller‑based hardware design
Analog circuit design
Closed‑loop temperature control
AC power design (single‑phase and three‑phase)
High‑voltage design (≥1 kV, typically low power)
Motor control
Human‑machine interface (HMI) design
System‑level architecture
PCB/PWB design and PWA practices
Wire harness design
Clear written and verbal communication with strong documentation discipline
Effective collaboration and facilitation skills; sensitivity to multi‑disciplinary stakeholder needs
Awareness of design impacts across the broader team and product lifecycle
Education & experience
Master’s degree, or Bachelor’s degree with substantial related experience
7+ years of relevant, hands‑on electrical engineering experience
Reporting
This role reports to the Manager, Electronics Research & Engineering, or the Manager, RF Products.
