Laser Systems Control Engineer

Lightmatter builds chips for artificial intelligence computing that leverage unique properties of light for efficient computing and communications. If you're a collaborative engineer or scientist who has a passion for innovation, solving challenging technical problems, and doing impactful work like building the world's first photonics-accelerated computers, consider joining the team at Lightmatter!

We are hiring a Laser Systems Control Engineer to join our team. In this role, you will be responsible for bringup, configuration, and stabilization of multiwavelength laser systems for datacenter AI communications. You will collaborate closely with a cross-functional team including, photonics, packaging, analog/digital design, and software engineers, to design and implement control algorithms that ensure the laser solution meets stability, power, and performance specifications across all operating conditions.

Join a tight-knit team where each individual’s contributions directly influence the company's and product's success. You'll have the opportunity to build innovative laser solutions from the ground up and tackle groundbreaking challenges. Work with people who love to build and thrive in diverse technical environments where great ideas are prioritized.

Responsibilities:

• Design control algorithms for laser power and wavelength stabilization across various thermal environments and product life cycles for Lightmatter’s laser modules.
• Actively coordinate with engineers and architects across various disciplines/teams, such as Lightmatter’s Passage SOC, photonic systems design, thermal engineering, packaging, analog design, and software engineering, to meet power consumption, performance, and production requirements.
• Architect optical components (integrated and bulk optics) such as filters for multiplexing, demultiplexing purposes, and either design these devices or work with photonics engineers to implement the designs.
• Coordinate with the test and validation team on calibration routines for packaging and assembly.
• Deliver laser module datasheet documentation related to laser power management, supply noise requirements, stability, and control.
• Support design failure mode and error analysis for each laser solution.
• Select and/or codesign with vendors an appropriate PMIC approach to drive and control highly integrated multi-wavelength laser modules in a data center environment.
• Prototype control algorithms in simulation and in a laboratory environment to assess performance against manufacturing variations and external aggressors.

Requirements

• M.S. or PhD in Photonics, Electrical Engineering, Software Engineering, or a related field.
• Experience developing laser stabilization and control architectures.
• Experience in conveying complex technical concepts to both technical and non-technical stakeholders, ensuring clear communication and alignment across teams.

Preferred Qualifications:

• Hands-on experience testing control algorithms on prototype samples and EVKs.
• Experience in product development for high volume applications.
• Experience in silicon photonics with design for manufacturing and reliability.
• Knowledge of signal processing and digital control.
• Willing and able to learn quickly, with a self-starter mindset and a 'no task is too big or too small' attitude.
• Excellent written and verbal communication skills.

Benefits

• Comprehensive Health Care Plan (Medical, Dental & Vision)
• 401k matching
• Life Insurance (Basic, Voluntary & AD&D)
• Generous Time Off (Vacation, Sick & Public Holidays)
• Paid Family Leave
• Short Term & Long Term Disability
• Training & Development
• Flexible, hybrid workplace model
• Stock Option Plan

We offer competitive compensation. The base salary range for this role, inclusive of all US locations, is $200,000- $250,000. Your base salary will be determined based on location, experience, educational background, and market data.
