Senior / Staff 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 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:

• Scheduler Development: Implement and optimize sophisticated algorithms for multi-day, multi-agent scheduling. You will maximize throughput and prevent deadlocks in a shared-resource environment with variable execution times**.**
• Resource Allocation: Develop logic to intelligently manage shared resources (e.g., incubators, liquid handlers) across parallel manufacturing batches.
• Distributed Systems Design: Architect and implement the software layer that manages the state and coordination of a multi-robot cluster.
• Resilient Orchestration: Design logic to maintain production continuity during hardware interruptions. You will implement mechanisms to isolate specific failures, ensuring that unaffected batches continue processing while the affected resources are addressed.
• Cloud-Cluster Connectivity: Implement the communication layer connecting on-premise robotic clusters with our AWS backend, focusing on reliable state synchronization and data persistence.
• Simulation & Testing: Build fast, discrete-event simulations to validate scheduling logic and throughput assumptions before code hits physical hardware.
• CI/CD & DevOps: Maintain and improve automated integration test suites to ensure the reliability of complex, non-deterministic systems.
• Mentorship: Mentor junior engineers, conduct code reviews, and champion software engineering best practices (clean architecture, testing patterns) to elevate the team.

Qualifications:

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related discipline.
• 5+ years of professional experience in software engineering, with a focus on backend systems, distributed systems, or complex logic.
• Expertise in Python and a strong command of software engineering fundamentals (e.g., system design, concurrency patterns, distributed architecture).
• Strong ability to implement complex logic and search algorithms (e.g., DFS/BFS, graph traversal, constraint satisfaction). You don't need prior robotics experience, but you must be excited to solve hard optimization problems.
• Excellent communication and problem-solving skills, with the ability to translate complex biological process requirements into software logic.
• Comfortable working in a fast-paced, technically challenging startup environment. Ability to balance context switching between multiple projects.

Additional Qualifications – Considered a plus:

• Hands-on experience with AWS (Lambda, IoT Core, DynamoDB) and container orchestration.
• Familiarity with interfacing with hardware or instruments via standard protocols (TCP/IP, WebSocket, REST, Serial).
• Deep comfort working in Linux environments, including networking configuration, systemd services, and shell scripting.
• Experience implementing monitoring and alerting for distributed systems.
