Hardware Engineer

G5 Infrared a LightPath Technologies company is a leading global provider of precision optics and photonics solutions, serving defense, aerospace, medical, and industrial markets. With decades of expertise and a strong culture of innovation, LightPath designs and manufactures advanced optical components and systems that power some of the world’s most demanding applications. We offer a collaborative, technology-driven environment, opportunities to work on cutting-edge programs, and a comprehensive benefits package that supports our employees’ health, growth, and work-life balance.

We are currently looking for a Hardware Engineer to join our team onsite in our Hudson, NH office. We offer a professional, high-energy culture where employees are empowered to succeed.

This position will support the design, development, and manufacturing introduction of new thermal imaging camera products. The successful candidate will contribute to all phases of the hardware development lifecycle—from initial circuit design through prototype bring-up and transition to production. This role offers significant hands-on experience with modern EDA tools, lab debug of sophisticated cooled-detector camera electronics, and direct collaboration with engineering, manufacturing, and external vendors. It is an excellent opportunity for an early-career engineer to grow technical breadth while delivering real products to customers in security, defense, and critical-infrastructure markets.

Responsibilities:

• Perform circuit design and analysis for analog, digital, mixed-signal, and power circuits used in thermal imaging camera products.
• Capture schematics and execute PCB layout using Altium Designer, working from initial component selection through DRC-clean, manufacturable boards.
• Create and maintain Bills of Materials (BOMs) and engineering documentation; manage BOM data and engineering change orders in the company ERP system.
• Work closely with the manufacturing team to introduce new products to production, including DFM/DFT reviews, pilot builds, yield improvement, and resolution of production-floor issues.
• Coordinate with external vendors for PCB fabrication and assembly of engineering prototypes; manage quotes, fab/assembly data packages, and quality issues.
• Perform SMT and through-hole soldering, rework, and modification of prototype assemblies.
• Conduct lab bring-up, debug, and characterization of prototype camera hardware using oscilloscopes, logic analyzers, spectrum analyzers, multimeters, power supplies, and other lab instrumentation.
• Support integration and test of cooled MWIR detector electronics, motorized zoom lens control, video output (HD-SDI / IP), and serial command interfaces (RS-232/422).
• Author and maintain test procedures, design verification reports, and product documentation.
• Support sustaining engineering activities for products in production, including component obsolescence and design refresh efforts.
• Collaborate effectively with cross-functional teams including senior electrical, optical, mechanical, software, manufacturing, and quality engineering.
