Senior Software Developer In Test Jobs in Petaluma, CA

At Glydways, our Systems team is responsible for architecting and verifying complex functional, logical, hardware, and software systems. We work across autonomy, vehicle hardware, safety, infrastructure, and operations to ensure the Glydways system is safe, reliable, and a great product experience. Sitting at the intersection of product vision and engineering execution, we own system requirements, the architecture of safety functions, vehicle definition, and infrastructure guidelines.

As a Senior Systems Engineer - GATN (Glydways Automated Transit Network), you will be the technical owner for how new features and system changes show up on the guideway. You will:

• Design, create requirements, and demonstrate novel features required of our public transit system.
• Judge the health of safety functions and guardrails using logs, metrics, and ontrack behavior.
• Define and execute integration test plans for new GATN capabilities using data-driven methods.
• Drive issues to closure so that the system can operate safely and hit its availability targets.

You'll work handson at the track (e.g., GDF2 and project sites), in logs and dashboards, and in tools to turn "we need this to work on the track" into concrete scenarios, parameters, and decisions. We prefer to have this position on-site 3 or 4 days a week at Richmond, CA, but will consider remote for the right candidate.

This role is ideal for someone who has shipped complex hardware/software systems, enjoys integration and test work, and is comfortable taming chaos in a multiteam environment. 

We're building the entire transit solution! It will operate safely and reliably, and we have to build not only the rider experience from ticketing to destination, but design the day in the life of each vehicle prior to and during business hours.

• Own feature landing for GATN: Design, plan and execute integration of new system capabilities on the track (product features including reduced headways, failoperational behaviors, meeting availability targets, ticket kiosk flows, dispatch behaviors, new ATP functions).
• Define and run integration scenarios: Design Tier 2+ integration scenarios that exercise safety functions, throughput behaviors, and operational workflows across vehicles, wayside, and dispatch / OCC.
• Improve regression and mileage test suites: Improve the regression test suite and mileageaccumulation campaigns that gate releases, including test selection, ordering, and coverage criteria for GATN features.
• Guardrail and safetyfunction health: Review logs, metrics, and track behavior to judge the health of safety functions (e.g., separation assurance, route obstruction, emergency stop behaviors), and recommend parameter or design changes where needed.
• Drive release readiness: Partner with Systems Engineering, Autonomy, Vehicle SI, and Operations to define entry/exit criteria for ontrack testing, release candidates, and feature "go live" decisions.
• Coordinate multivehicle and multisite integration: Support integration efforts across project sites (e.g., GDF2 and customer locations), including parity targets, mobile test sites, and projectspecific constraints.
• Translate requirements into track reality: Write systemlevel requirements, CONOPs, and analysis outputs from the Systems Engineering & Architecture team and ensure they are implemented, testable, and validated on the GATN.
• Triage and root cause issues: Lead technical triage when integration or regression tests fail-coordinate logs, reproduce issues, work with domain owners, and drive to clear, documented resolutions.
• Improve integration process and tooling: Identify gaps in test infrastructure, logging, metrics, and configuration management that slow down feature landing; propose and help implement improvements.
• Communicate clearly and often: Provide crisp status on feature readiness, risks, and blockers; document decisions and operational guardrails so that product, operations, and leadership have a clear picture of system state.

• Can turn ambiguity into clarity: drive vague, high-level questions into concrete, testable requirements.
• Knows which questions matter most: generates many, but focuses on the critical few.
• Has shipped products.
• Brings cross-functional depth: ideally with a background in mechanical, electrical, embedded, or software design engineering.
• Raises the bar for rigor: requirements traceability, verification planning, safety analysis, and disciplined systems thinking.

Required

• Bachelor's degree in Engineering, Computer Science, or a related technical field.
• 4+ years of experience in a relevant industry.
• 1+ years of experience in systems integration and test, system test, or verification and validation for complex hardware/software systems
• Ability to collaborate across diverse teams (autonomy, embedded, systems, operations, product) and drive alignment without direct authority.
• Excellent communication and collaboration skills.
• Experience planning and executing integration or systems-level test campaigns, including scenario design, success criteria and analysis.
• Strong root-cause skills across software and hardware interfaces
• Comfort working hands-on at the test track
• A desire to figure out what to build next
  

Preferred / Bonus

• Master's degree in Systems, Mechanical, Electrical, or Software Engineering.
• Experience with autonomous vehicles, robotics, transit systems, or complex hardware/software integrated products
• Familiarity with system test environments (HIL, SIL, simulation frameworks).
• Experience with systems engineering tools (e.g., Jama, SysML, DOORS).
• Proven track record of delivering safety-critical products to market.
• Exposure to safety and reliability topics (e.g., safety functions, operational envelopes, availability metrics, RAMS) and how they show up in system integration work.
