About the Role
As an Electrical Engineer, Photonics, you will work across our full product line, from ground-based telescopes to on-orbit optical payloads. You will design, integrate, and validate photonic and electro-optical systems that enable high-performance sensing, imaging, and data acquisition in both terrestrial and space environments.
This role sits at the intersection of electronics, optics, and physics. You will own the electrical design and integration of optical sensors, detectors, laser-based systems, and high-speed signal chains, ensuring performance is maintained through challenging conditions including thermal extremes, vacuum, radiation, and long-duration autonomous operation. You will work closely with optical, mechanical, and software teams to deliver tightly integrated systems.
What You'll Do
-
Design and develop electrical systems for photonic and electro-optical subsystems, including detectors, sensors, laser interfaces, and high-speed data acquisition chains.
-
Own schematic capture, PCB design, and bring-up for low-noise analog and mixed-signal circuits supporting optical instrumentation.
-
Develop and optimize signal chains for photodetectors (e.g., CMOS, CCD, APD, SPAD), including amplification, filtering, digitization, and noise mitigation.
-
Design for signal integrity and low-noise performance in high-sensitivity optical systems, including grounding, shielding, and layout strategies.
-
Bring up and validate high-speed interfaces such as MIPI, LVDS, JESD, or similar data links used in imaging and sensor systems.
-
Collaborate with optical engineers to define electrical interfaces, alignment sensitivities, and performance requirements across optomechanical assemblies.
