Senior Hardware Engineer, Linux Platforms
About the role
PTx is investing in next-generation Linux-class hardware across our agriculture technology platform. We are hiring a Hardware Engineer to own Linux-capable embedded boards end-to-end, from schematic capture through PCB layout, for products deployed in demanding off-highway environments. This role anchors our platform-wide Linux hardware roadmap and partners daily with firmware, mechanical, compliance, and test engineering teams based in Tremont, IL.
What you will do
Architect and capture schematics for Linux-class embedded boards built around application-class SoCs (NXP i.MX, TI Sitara, or comparable).
Perform PCB layout in Altium Designer, including DDR4 routing, high-speed serial (USB 3.x, PCIe, MIPI CSI/DSI, Gigabit Ethernet), and mixed-signal partitioning.
Own the power architecture: PMIC selection, rail sequencing, brown-out behavior, and low-noise rail planning for sensitive analog and high-speed digital.
Follow design-for-manufacturing (DFM), design-for-test (DFT), and EMC best practices to deliver high-quality production boards.
Drive boards from concept to production with minimal respins, balancing design rigor with schedule pressure.
Build reusable reference designs and design patterns that accelerate downstream product development across the platform.
Required qualifications
BS in Electrical Engineering or equivalent technical degree.

3+ years of professional hardware design experience, with at least some years on Linux-class SoC boards.
Demonstrated single-owner experience on both schematic capture and PCB layout for production hardware.
Proficiency in Altium Designer.
Direct experience with DDR3 or DDR4 routing, signal integrity analysis, and timing closure.
Working knowledge of high-speed serial interfaces, including USB 3.x, PCIe Gen2/3, MIPI CSI/DSI, and Gigabit Ethernet.
Power architecture experience, including PMIC selection, rail sequencing, and low-noise rail design.
EMC/EMI design and pre-compliance debug experience.
Preferred qualifications
MS in Electrical Engineering.
7+ years of professional hardware design experience.
Direct experience with NXP i.MX 95 or comparable application-class SoCs (TI Sitara, Qualcomm, Renesas RZ).
Experience designing for Power over Ethernet (PoE / PoE+), and/or 100BaseT1 (Automotive 2 Wire Ethernet).
Experience with tablet size display technology.
Experience with high-volume hardware deployed in harsh environments (off-highway, agriculture, automotive, industrial).
Experience working in a PLM environment (Windchill, Teamcenter, or equivalent).
Education
BS in Electrical Engineering required. MS in Electrical Engineering preferred.
