Senior Robotics Test Engineer

About Multiply Labs

Multiply Labs is a cutting‑edge startup based in San Francisco, California, supported by top‑tier tech and life science investors such as Casdin Capital, Lux Capital, and Y Combinator. Our mission is to build the best robots in the world, and use them to make the most advanced life‑saving therapies accessible to all.

We are revolutionizing the manufacturing of cell therapies by developing advanced robotic systems designed to automate and scale the production of these life‑saving treatments. Our robots empower biopharma companies to produce cell therapies at scale without significantly changing their existing processes, reducing regulatory barriers and risks. While traditional approaches are time‑consuming and lead to extremely high costs for patients (typically $1M+ per patient), using robotics can make these transformative treatments more accessible and affordable to patients in need.

As a Senior Robotics Test Engineer, you will be a key technical leader responsible for ensuring the reliability and precision of the robotics software that powers our automated manufacturing systems. Working at the intersection of robotics and biopharma, you will build the infrastructure that validates our technology before it is deployed to our cell therapy manufacturing systems. This role is for a detail‑oriented, senior engineer who can understand system‑level tradeoffs and is passionate about building robust automated testing frameworks that directly impact patient lives.

• Test Infrastructure & Development: Collaborating with hardware and software teams to standardize testing across the organization. You will design the testing architecture and infrastructure, build automated frameworks, and maintain the comprehensive test suites (automated and manual) that validate our robotics software and firmware.
• Subsystem Validation: Leading the planning and validation of new subsystems. You will work closely with hardware teams to test prototypes, compile data, and execute on feedback to drive design improvements.
• System Integration: Partnering with Hardware, Software, and Field Engineering to plan and execute full‑system integration tests within our manufacturing clusters.
• Debugging & Issue Resolution: Investigating, reproducing, and resolving errors across the full system. You will collaborate with Field Engineering to triage failures, analyze logs to identify root causes, and validate fixes through targeted testing to ensure continuous operation.
• Quality Assurance & Strategy: Contributing to test planning, documentation, and reliability metrics to ensure the scalability and long‑term stability of our automated systems.

• Bachelor’s or Master’s degree in Computer Science, Robotics, Engineering, or a related discipline.
• 5+ years of professional experience in software test engineering, specifically within robotics or complex electromechanical systems.
• Strong expertise in Python and experience building automated test frameworks from scratch.
• Proven experience planning and validating new subsystems with a detail‑oriented mindset.
• Ability to understand and navigate complex system‑level tradeoffs between hardware constraints and software flexibility.
• Excellent communication and collaboration skills to work effectively across hardware and software teams.

• Experience with project management tools (e.g., Jira) to align cross‑functional teams and drive testing milestones.
• Hands‑on experience with robotics simulation environments (e.g., Isaac Sim, Gazebo) for automated testing.
• Experience working in a regulated industry (e.g., GxP, ISO standards).

• Ability to reach, stoop, crouch, and kneel; this specifically includes the need to physically enter, stand, or crouch inside a robotic cluster for testing, debugging, or manual intervention.
• Ability to lift up to 25 pounds (e.g., test fixtures, replacement parts, tools) and lift up to 5 pounds overhead.
• Manual dexterity required for using hand tools, cabling, and making mechanical adjustments.
