Senior Hardware Engineer

We are looking for a PLC Integration Engineer to own the network and control-system layer of Laminar’s customer deployments. This is a hands-on technical role at the intersection of industrial automation, IT/OT networking, and edge software — you will be the person who gets Laminar’s sensors and edge devices online, stable, and talking to Food and Beverage factory control systems. 
You will work directly with customer IT and OT teams to configure networks, commission PLC connections, and troubleshoot integration issues from first install through steady-state operation. When things break, you dig in and fix them. When patterns emerge, you document them, so the next deployment moves faster. 
This role is a launchpad. Engineers who thrive here grow into edge software engineering, senior FDE roles with full account ownership, or go-to-market paths in sales and solutions engineering.

What You Will Do

- Design and protype PCBs from commercially available and custom sensors using KiCAD, SolidWorks, and simulation software such as PSPICE

- Design mechanical housings using Solidworks tailored to difficult industrial deployment environments

- Develop and implement test strategies alongside the Laminar Data Analysis team. Collect and present this data in informal and formal reviews to allow for rapid analysis and sensor comparisons.

- Lead internal teams working on new system design, with a focus on quick evaluation and an extremely high level of system ownership.

- Integrate sensors to established testing platform using Zephyr RTOS

- Bring new ideas and creatively pursue new approaches to product sensing to solve critical problems for our clients.

- Contribute to the overall hardware team by providing design, assembly, and debug assistance on multiple projects.
