Kforce's client, a growing and established technology company in Kirkland, WA, is seeking an Optoelectronics Systems Engineer. This role will play a key role in a small cross-functional team in a fast-paced environment. This is a hands-on role that blends optics, electronics, and software. You'll work closely with the team to support the hardware design, system bring-up, software development, testing, and calibration of our next-generation Optoelectronic systems. The Optoelectronic Systems Engineer must have excellent interpersonal skills and work well across internal functional units as well as with third party suppliers, partners, and customers. Responsibilities: * Contribute to the design and development of the systems, collaborating closely with hardware, optics, and FPGA teams to shape system architecture and functionality * Perform hands-on PCB bring-up, validation, and debug for mixed-signal and optoelectronic assemblies * Develop and maintain Python-based system control software for lidar systems, interfacing with optical and electronic subsystems * Work closely with FPGA engineers to validate system PCB signals and digital interfaces, to ensure reliable timing and communication between system components * Support characterization and calibration of optoelectronic components (lasers, photodetectors, optics) in lab and prototype environments * Work with lab equipment such as oscilloscopes, power meters, and optical test benches * Collaborate with cross-functional teams (optics, firmware, mechanical) to support system integration and testing * Participate in hardware and system design reviews, focusing on system integration, testability, and robustness for electro-mechanical systems * Develop and refine calibration routines to optimize system performance and consistency * Diagnose and resolve system-level issues involving electronics, optics, and embedded software
