We are starting with the liver, where toxicity remains a leading cause of drug failure. Our high-throughput human liver safety platform combines advanced human cell systems with imaging, transcriptomics, mass spectrometry, and drug metabolism measurements. Our AI agents integrate these data with chemical structure, human exposure, and thousands of clinical reference compounds to predict whether a drug will be toxic in humans, why, and how to make it safer.\nWe work with seven of the world’s top twenty pharmaceutical companies to design safety into molecules from the earliest stages. This applied work feeds directly into our partnerships with leading frontier AI labs, turning real discovery challenges and experimental feedback loops into scientific skill trees and reinforcement learning environments that train increasingly superhuman scientists. We then deploy these frontier models to make cancer therapies safer, unlock treatments for chronic diseases that demand exceptional safety, revive promising drugs abandoned because of toxicity, and much more.\nOur ultimate ambition is to build a superhuman AI agent that predicts how a drug will behave across all major human organ systems before the first patient receives it. With insanely accurate safety predictions, we aim to enable rapid, high-throughput testing of novel drugs in humans with zero risk of toxicity. This is the key to unlocking an abundance of ultra safe, effective medicines.\nWhat you will do:\nBuild and operate the shared infrastructure behind Axiom’s scientific data pipelines, AI agents, research workflows, and Translate product.\n\nOwn cloud infrastructure, compute, storage, databases, and networking, making systems reliable, secure, scalable, and cost-efficient.\n\nDevelop workflow orchestration that lets scientists, engineers, and agents run complex computational pipelines with clear dependencies, durable state, and recovery from failures.\n\nBuild secure execution environments for agents, with controlled access to scientific tools, models, and data, strict customer isolation, and resource and budget limits.\n\nMake scientific results reproducible through data versioning, lineage, snapshots, and automated checks that catch stale inputs, inconsistent features, and incomplete outputs.\n\nBuild fast development environments, CI, and deployment systems that let people and agents ship changes confidently across development, staging, and production.\n\nOwn authentication, permissions, secrets, and workload identity across internal systems, customer workspaces, laboratory partners, and model providers.\n\nMake systems observable through logs, metrics, traces, execution histories, and alerts that help people and agents investigate failures and verify results.\n\nManage database migrations, backups, and recovery, and resolve production issues across Axiom’s platform and infrastructure providers.\n\nWork directly with scientists, ML researchers, and product engineers to remove operational bottlenecks and turn recurring manual work into reliable, self-service tools.\n\nWhat we look for:\nExceptional software engineering ability and experience building reliable production systems, with depth in infrastructure, distributed systems, platform engineering, or developer tools.\n\nStrong systems judgment. You simplify complex problems, choose clear abstractions, and build systems that remain understandable as they grow.\n\nEnd-to-end ownership. You identify what matters, make progress without a detailed specification, and follow through from design to deployment and operation.\n\nAn instinct for reliability and correctness. You anticipate failure modes, make failures visible, and prevent silent errors from reaching scientific results or customers.\n\nStrong security judgment. You understand permissions, credentials, isolation, and trust boundaries, and make secure workflows easy to use.\n\nA talent for debugging across application code, databases, networks, cloud services, and execution environments.\n\nExperience building with AI agents and a drive to make them effective users of infrastructure, tools, and data, with appropriate controls and verification.\n\nCare for developer and scientist productivity. You notice recurring friction and replace manual work with dependable tools and automation.\n\nClear communication, intellectual curiosity, and the willingness to learn biology, chemistry, and ML to build better systems for scientific discovery.\n\nTechnical skills we value:\nPython, SQL, asynchronous programming, APIs, and production backend systems.\n\nAWS, Modal, Docker, Terraform, cloud networking, and infrastructure as code.\n\nDuckDB/MotherDuck, Postgres, S3, Parquet, database migrations, backups, and recovery.\n\nWorkflow orchestration, dependency management, distributed execution, checkpointing, retries, and durable state.\n\nData versioning, lineage, reproducible pipelines, and automated consistency checks.\n\nIAM, SSO, OAuth/OIDC, workload identity, secrets management, and customer isolation.\n\nAgent execution environments, sandboxing, tool access, model APIs, and resource and budget controls.\n\nCI/CD, GitHub Actions, isolated development environments, automated testing, and deployment strategies.\n\nObservability, including structured logs, metrics, tracing, alerting, Datadog, and production debugging.\n\nTypeScript, SvelteKit, Vercel, and internal developer tools are a plus.","description_format":"text","description_chars":5697,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Drug
