Senior / Staff Robotics Software Engineer

Join the Future of Robotic Biomanufacturing!
Multiply Labs is a robotics company on a mission to solve a significant bottleneck in modern medicine: the manufacturing of life-saving advanced biologics - including cell therapies, gene therapies, mRNA therapies, and more.
Currently, advanced biological therapies are produced through manual, labor-intensive processes. This keeps costs astronomical—often exceeding $0.5M-$2M per patient—and limits access to only a fraction of those in need. 
As labor scarcity for scientists compound against increased product complexity and sky-high costs of failure, the emergence of robotics and AI makes the automated manufacturing of biologics feasible, reliable, and economically scalable. 
We envision that the biomanufacturing factory of the future is fully robotic - closed, automated, and scalable, making therapeutics for some of the most important indications for patients today widely accessible.  
Why This Matters
We don’t just build robots; we build the infrastructure for the next generation of biologics manufacturing. Our technology allows biopharma companies to scale production without redesigning their science, drastically lowering regulatory hurdles and bringing costs down to a level where these treatments can actually reach patients.
The Stack & The Scale
The Mission: Build the world’s best robots to make life-saving therapies accessible to all.The Technology: Advanced robotic orchestration, high-precision automation, cloud-integrated hardware-software systems, dextrous manipulation, and imitation learning.The Location: Headquartered in San Francisco, CA.The Backing: Supported by premier investors, including Casdin Capital, Lux Capital, and Y Combinator.
About the Role
As a senior member of our Robotics Software Engineering Team, you will be a key technical leader responsible for the intelligent software that powers our automated manufacturing systems. Working at the intersection of robotics and biopharma, you'll collaborate with a world-class team to solve complex challenges. This role is for a passionate, hands-on engineer dedicated to building robust systems that have a direct impact on patient lives.

Responsibilities include:

• System Design & Architecture: Designing and implementing production-ready software for our robotic platforms, spanning from low-level hardware communication to high-level robotic logic and system behaviors.
• Core Algorithm Development: Implementing and optimizing sophisticated algorithms for trajectory planning, robotic interaction, motion control, and integrating data from various sensors.
• Simulation & Testing: Building and maintaining high-fidelity simulations for validation and contributing to our automated test suites (CI/CD) to ensure software robustness.
• Cross-Functional Collaboration: Working closely with mechanical and system software teams to integrate and troubleshoot complex, system-level robotics challenges.
• Mentorship & Best Practices: Mentoring other engineers and championing software best practices to elevate the entire team.

Qualifications

• Bachelor’s or Master’s degree in Computer Science, Robotics, Engineering, or a related discipline.
• 5+ years of professional experience developing software for robotic or complex electromechanical systems.
• Expertise in Python and a strong command of software engineering fundamentals (e.g., version control with Git, automated testing, CI/CD).
• Deep understanding of robotics principles, including kinematics, dynamics, motion planning, and control theory.
• Experience leading cross-functional projects and a demonstrated ability to deliver on technical roadmaps.
• Excellent communication, collaboration, and problem-solving skills, with comfort in a fast-paced startup environment.

Nice to Haves

• Hands-on experience with robotics simulation environments (e.g., Isaac Sim, Gazebo, PyBullet).
• Familiarity with machine learning frameworks (e.g., PyTorch, TensorFlow) and their application to robotics (e.g., computer vision, imitation learning).
• Experience working in a regulated industry (e.g., GxP, ISO standards).
