Principal Laser Controls Engineer

We are seeking a Principal Laser Controls Engineer to define and drive the control architecture for advanced laser-based optical modules. This role demands deep expertise in laser physics, control systems, and embedded implementation. You will own the technical vision for laser control-spanning optical power regulation, current control, thermal stabilization, and wavelength calibration-ensuring robust, scalable, and production-ready solutions across the full product lifecycle., * Define and own the end-to-end laser module control architecture, including: + APC (Automatic Power Control) loops for stable optical output + ACC (Automatic Current Control) strategies for laser drive optimization + Automatic calibration frameworks (power, current, aging compensation, temperature drift) + TEC (Thermoelectric Cooler) control for wavelength and thermal stability

• Lead the design, modeling, and optimization of laser control loops, accounting for: + Laser non-linearities (L-I curves, threshold behavior) + Aging, degradation, and environmental variations + Noise, stability margins, and transient performance

• Architect closed-loop control strategies that balance performance, reliability, and manufacturability across PVT and lifetime conditions

• Develop and own module embedded laser control firmware, including: + Real-time control loops + Calibration routines (factory + in-field) + Fault detection, protection, and recovery mechanisms

• Establish modeling and correlation frameworks linking simulation to silicon and optical performance, * Define the control and calibration backbone of next-generation laser products
• High ownership across laser physics, control algorithms, and system integration
• Opportunity to shape product direction in a fast-paced, execution-driven environment

• MS or PhD in Electrical Engineering, Photonics, Controls, or related field
• ~12-15+ years of experience with deep focus on laser systems and control

• Strong expertise in: + APC/ACC loop design and optimization + Laser behavior (L-I-V characteristics, thermal effects, degradation mechanisms) + Feedback control theory and real-world implementation

• Proven experience implementing calibration algorithms (factory and adaptive/in-field)
• Strong embedded firmware background for real-time control systems
• Proficiency in modeling and simulation (MATLAB/Python/Simulink or equivalent), with demonstrated correlation to hardware
• Track record of driving system-level architecture and influencing cross-functional teams, * Experience with pluggable optical modules and CMIS
• Familiarity with high-speed optical links, SerDes
• Experience with reliability engineering (lifetime drift, burn-in, field performance)
• Exposure to high-volume manufacturing, yield optimization, and test infrastructure
