About the Role

As a Senior Software Engineer at Formation Bio, you will build high-leverage software across the organization, transforming ambiguous problems into products and systems that enhance decision-making and accelerate progress for people, applications, AI Enabled Employees, and Agents. This is an AI-native engineering role where you will utilize modern AI and agentic development tools as a core part of your workflow and contribute to the responsible creation of AI-integrated software. You will be expected to navigate evolving priorities, make progress with incomplete information, identify high-value paths, communicate tradeoffs, and adapt quickly to new information.

Responsibilities

  • Own meaningful product or platform outcomes from problem definition through design, implementation, launch, and iteration.
  • Build and operate production services, APIs, integrations, databases, asynchronous workflows, and distributed systems.
  • Build software for people, applications, AI Enabled Employees, and Agents, including the tools, APIs, permissions, state, observability, and failure handling required for reliable use.
  • Design and ship AI-enabled and agentic workflows, including tool use, retrieval, data access, evaluation, and appropriate human review.
  • Use LLMs and agentic coding systems daily for exploration, prototyping, implementation, testing, debugging, documentation, and automation while maintaining a high bar for validation.
  • Partner with Data Engineering on application data models, data products, data contracts, and access patterns.
  • Partner with Data Science on ML-powered capabilities, model interfaces, evaluation, and production integration.
  • Partner with SRE on deployment, reliability, observability, security, and infrastructure decisions.
  • Make pragmatic tradeoffs between speed, quality, maintainability, and future flexibility.
  • Use engineering rigor proportional to the risk and context of the system.
  • Reprioritize quickly as new information changes the highest-value path, and communicate decisions and tradeoffs clearly to technical and non-technical partners.
  • Review designs and code, mentor engineers, and raise the bar for product judgment and engineering quality.

Requirements

  • 5+ years of experience building and shipping production software, or equivalent senior-level experience.
  • Experience in pharmaceutical, biology, and/or biotechnology software and data is a strong plus.
  • Strong backend and systems engineering fundamentals, including APIs, distributed systems, databases, cloud services, and asynchronous workflows.
  • Daily experience using AI tools, LLMs, or agentic development systems as part of the engineering workflow.
  • Experience building AI-enabled software, agentic workflows, retrieval systems, tool integrations, or other ML-powered products is a strong plus.
  • Familiarity with ML concepts such as training versus inference, embeddings, retrieval, evaluation, data quality, and model limitations is a plus.
  • Strong product judgment and the ability to make progress with incomplete information, identify high-value problems, and adapt quickly as priorities change.
  • Experience operating production software with appropriate testing, observability, security, and follow-through after launch.
  • We value full-stack range, with a primary emphasis on backend, systems, product, and AI engineering.
  • Exceptional communication and collaboration skills across Product Engineering, Data Engineering, Data Science, SRE, and non-technical partners.
