Company

Laminar builds self-driving factory systems that combine inline sensors, physics- and chemistry-grounded AI models, and real-time process control software to improve industrial productivity and sustainability.

What you will do

• Design and prototype PCBs for commercial and custom sensors using KiCad, SolidWorks, and simulation tools such as PSpice.
• Design mechanical housings for sensor systems deployed in demanding industrial environments.
• Develop test strategies, collect and analyze sensor performance data, and present results in technical reviews.
• Lead internal system-design efforts focused on rapid evaluation, prototyping, and strong ownership.
• Integrate sensors with established testing platforms using Zephyr RTOS.
• Provide design, assembly, debugging, and electromechanical development support across multiple hardware projects.

Requirements

• 5+ years of experience in electronics design, mechanical design, and data analysis.
• Experience with PCB SMD and THT soldering, rework, troubleshooting, oscilloscopes, digital signal analysis, switch-mode power supplies, and EMI troubleshooting.
• PCB design experience with advanced microcontrollers, low-noise analog sensor systems, industrial communications protocols, and high-density layouts.
• Product development experience covering new-product bring-up and R&D, plus embedded-systems coding experience, preferably with Zephyr RTOS or a similar platform.
• Experience designing CNC-machined housings, watertight seals, and industrial product interfaces, together with a generalist electromechanical mindset.
• Clear, efficient communication and the ability to balance multiple projects and changing priorities.

Nice to have

• Significant experience across both electrical and mechanical engineering.
• Full product-development lifecycle experience from concept through volume production and sunset.
• Experience with PCB contract manufacturers, machine shops, and design-for-manufacturing practices.
• Mechanical design experience for difficult environments, including ATEX zones or automotive applications.
• RF experience, particularly antenna design, tuning, or RF spectroscopy.

Culture & Benefits

• Autonomous, hands-on environment with direct impact on product development and company culture.
• Medical, dental, vision, life insurance, disability, transportation, and health and wellness benefits.
• 401(k) plan with employer matching, equity, competitive salary, and bonus opportunities.
• Flexible time off, 12 company-paid holidays, and a conference and learning budget.
• Access to Greentown Labs and its cleantech startup network.

Hiring process

• Interviews include discussion of previous hardware and product-development projects.
• The process encourages applicants from diverse backgrounds who may not meet every listed requirement.
