At Machina Labs, we’re reshaping manufacturing through advanced robotics and machine learning. Our platform uses the largest 6‑axis robots on the market to form 2‑D sheets of metal into complex 3‑D parts, layer‑by‑layer. Traditional sheet metal production was designed for scale, not flexibility. It relies on costly dies and tooling that make lower‑volume projects prohibitively slow and expensive. We’re changing that. Whether you’re a startup building a few thousand airframes or an automaker prototyping next‑generation components, Machina Labs gives you the ability to iterate and manufacture at the speed of software.

With support from the venture arms of Toyota, NVIDIA, and Lockheed Martin, we’re accelerating the future of manufacturing, a future where factories are flexible, production is on‑demand, and innovation is unconstrained.

Machina Labs is seeking a Software Engineer In Test to own quality, validation, and release execution across our software platform as we develop and deploy new features and services.

This role is responsible for defining the quality strategy for the software stack, validating release candidates, and supporting deployments to production. You will build automated testing infrastructure, execute validation of new features, triage software issues, and act as a gatekeeper for software releases. The role partners closely with software engineers and collaborates with robotics and automation engineers when software changes impact production cells.

The ideal candidate combines strong software engineering fundamentals with deep experience in test automation, CI/CD pipelines, and production‑grade release processes.

• Own and drive quality strategy for the software stack, including TypeScript, React, Next.js, Python, and Azure GCC High.
• Define, formalize, and maintain test plans, test suites, and release criteria for software systems.
• Execute smoke tests, regression tests, and system validation of release candidates.
• Serve as release authority, approving or blocking promotion from release candidate to official production release.
• Design, implement, and maintain automated testing and validation pipelines integrated with CI/CD.
• Run tests and experiments for new features to validate functionality, performance, and reliability.
• Support deployment of software releases to Azure, including monitoring and initial issue response.
• Collect and synthesize feedback from users to inform quality improvements and testing priorities.
• Triage and support software issues, performing initial investigation and escalating to engineering teams as needed.
• Partner with Robotics and Automation Engineers in Test when required, including deployments to production cells, user support, and large‑scale release validation.
• Continuously improve testing tools, processes, and release workflows as the platform scales.

• Bachelor’s degree in Engineering, Computer Science, or comparable practical experience.
• Experience testing software systems, including writing test scripts or test code.
• Hands‑on experience with automated testing frameworks or tools.
• Ability to debug issues across software and automation interfaces.
• Strong problem‑solving and communication skills.

• Experience testing industrial automation systems, robotics, or hardware‑software integrated products.
• Familiarity with CI/CD pipelines, versioned deployments, and release validation.
• Experience supporting deployments and troubleshooting issues in production environments.
• Background working in small, fast‑moving engineering teams where quality ownership is critical.

$140,000 - $165,000 a year. Actual compensation will be determined based on experience, skills, qualifications, and geographic location. In addition to the provided base salary range, comprehensive benefits (Medical, Dental, Vision), PTO, and Stock Options.
