Temporary Embedded Linux Jobs in Michigan (NOW HIRING)

About the Role

We're looking for a hands-on Electrical Design Engineer to own the full lifecycle of hardware development for our IoT telematics products serving the construction industry. This role is currently filled by a third-party contractor — we're bringing it in-house because hardware is core to our business and we need someone embedded in the team who can move fast, make decisions, and take ownership.

You'll be the go-to person for everything electrical — from schematic capture through PCB layout, prototyping, validation, and production handoff. You'll work closely with our firmware, software, and manufacturing teams to deliver rugged, connected devices that operate in demanding field environments.

What You'll Do

- Own schematic design and PCB layout** for IoT telematics devices (multi-layer, mixed-signal boards with cellular/GNSS/BLE connectivity)

- Drive designs from concept through production — prototype builds, DVT, PVT, and manufacturing release

- Manage BOM, component selection, and sourcing with an eye toward cost, availability, and reliability

- Perform and coordinate hardware validation — functional testing, environmental qualification, EMC/EMI pre-compliance, and regulatory certification (FCC, IC, CE)

- Collaborate with firmware and embedded software engineers on hardware/software integration, pin assignments, peripheral interfaces, and debug

- Interface with our contract manufacturing operation to ensure designs are optimized for manufacturability (DFM) and testability (DFT)

- Create and maintain design documentation* — schematics, layout files, assembly drawings, test procedures, and design review packages

- Evaluate and select EDA tools, test equipment, and design methodologies appropriate for our product needs

What We're Looking For

Must Have

- 5+ years of electrical/electronics design experience, with at least 2 years focused on IoT, telematics, or connected embedded devices

- Demonstrated experience taking a hardware product from prototype through production — you've lived through DVT/PVT cycles and know what it takes

- Proficiency in schematic capture and PCB layout tools (Altium Designer preferred; KiCad, OrCAD, or equivalent accepted)

- Strong background in mixed-signal design: power management, RF/antenna integration (cellular, GNSS, BLE/Wi-Fi), low-power design

- Experience with regulatory compliance and certification processes (FCC, CE, UL)

- Experience with **high-speed digital design** — DDR memory interfaces, application processors, SoC integration, impedance-controlled routing, and signal integrity fundamentals

- Familiarity with common embedded interfaces: UART, SPI, I2C, USB, CAN, Ethernet

- **Comfort with RF concepts** — antenna matching, transmission line theory, RF front-end design, and working with cellular/GNSS/BLE modules

- Ability to read and debug at the board level — comfortable with oscilloscopes, logic analyzers, spectrum analyzers

Strongly Preferred

- Experience designing for harsh/outdoor environments (wide temp range, vibration, moisture/IP-rated enclosures)

- Background in automotive or construction telematics

- Experience working with contract manufacturers and understanding of DFM/DFT principles

- Exposure to PCBA test fixture design and production test development

- Familiarity with embedded Linux platforms (Yocto, Buildroot) at the hardware interface level
