About Plasmidsaurus Plasmidsaurus is on a mission to accelerate new cures and promote a healthier planet by unlocking a new level of productivity for scientists. Our sequencing services are used daily by thousands of innovators, including Nobel laureates, Fortune 100 pharma, and over 70,000 scientists. We began by revolutionizing plasmid sequencing, making it exponentially cheaper and faster, with innovative sequencing technologies and a global network of laboratories that turn samples into answers in hours, not weeks. Now we are expanding that same disruptive model across all of genomics. With the launch of our new RNA-seq service, we are taking a bold step toward our vision to sequence everything, providing scientists everywhere with faster, simpler, and more affordable access to the data that powers discovery. Every team member at Plasmidsaurus plays a crucial role in driving the future of biotech research. Together, we are building the world's most efficient sequencing engine that operates overnight, scales globally, and helps scientists make breakthroughs faster than ever before. Position Overview Technical lead + manager for the compute, data, AI, and security infrastructure that runs our sequencing operation. You will: Own core services that orchestrate lab devices (robots, sequencers, on-prem Linux servers) and the data ingestion pipeline Build cloud infrastructure and data pipelines to house, process, and deliver terabytes of sequencing data Design infrastructure to orchestrate millions of bioinformatics tasks (queues, workflow orchestration, scheduling) Build AI infrastructure and internal tooling to enable agentic systems: Quality Scientist Agents - monitor operations end-to-end, surface anomalies, and intervene/escalate when quality or reliability issues appear Logistics Agents - coordinate drivers around the world to move packages to labs and carriers Bioinformatics Coding Agents - long-running agents for adaptive analysis of diverse sample types with unknown/shifting data distributions Culture You are someone who: Enjoys high agency and high ownership work Can lead ambiguous, cross-functional projects from idea to production Is curious about learning from other people's expertise in scientific/biological domains Is excited to make an impact on the scientific community Is a life-long learner Is excited to work in a tight-knit fast-paced environment with a motivated team Values clear communication, mentorship, and helping others learn new skills Excited about building on the bleeding edge
