Senior Engineer, System Automation (Subsystems)

The role

This role involves designing and maintaining high-level Python control software for photonic, optical, electronic, and electro-optic subsystems. The engineer will translate hardware workflows into reusable APIs, automated routines, and tests within an existing system automation framework.

What you will do

• Design subsystem control abstractions for the System Automation framework
• Develop reusable Python APIs, functions, and automation routines
• Own hardware control code quality including testing and documentation
• Work with design leads to understand manual workflows and constraints
• Translate workflow needs into control software requirements, examples, and tests
• Debug subsystem automation issues involving Python, hardware, and data acquisition
• Contribute to subsystem operating procedure definitions
• Identify automation software needs and drive implementation to closure
• Support bring-up of new hardware generations

Required qualifications

• B.S., M.S., or Ph.D. in Computer Science, Computer Engineering, Electrical Engineering, Physics, or a related technical discipline
• 3+ years of software engineering experience in hardware, scientific, automation, test, embedded, control, or laboratory systems
• Strong Python software engineering skills
• Experience building APIs, automation workflows, instrument-control code, test code, or hardware-control software
• Experience working within existing software frameworks and following design patterns
• Ability to translate ambiguous hardware workflows into software requirements, routines, tests, and documentation
• Strong cross-functional communication and documentation skills

Nice to have

• Hands-on experience automating complex photonic, optical, laser, RF, electronic, or electro-optic hardware
• Familiarity with configuration files, SQL, data models, logs, dashboards, topology-aware systems, or control-system state models
• Experience integrating with services such as databases, observability tools, orchestration tools, internal APIs, or data acquisition systems
• Experience with calibration workflows, validation workflows, commissioning, lab automation, hardware-in-the-loop testing, or experimental control systems
• Track record of improving software quality in concert with non-software engineers

Benefits

• Competitive health coverage for you and your dependents
• 401(k) with company match
• Equity grants
• Access to financial wellness tools and planning resources
• Wellness benefits
• Family support programs
• Life and disability insurance
• Paid leave programs
• Company-designated paid holidays
• Discretionary time off (DTO)
• End-of-year company shutdown
