Senior Software Engineer, App

Cambridge, MA USA;
San Francisco, CA USA Your Impact at LILA

Scientists shouldn't have to context‑switch between a dozen tools to go from hypothesis to result. We're building the platform that makes this a reality — and we need engineers who want to solve problems no one has solved before.

The Application Team sits at the center of LILA — the integration point where Machine Learning, Life Sciences, Physical Sciences, and Software become one AI‑native experience that carries a scientist from hypothesis to experiment to breakthrough results.

• AI isn’t a feature here — it’s the architecture. Agent frameworks, tools, and LLM orchestration are core primitives, not bolt‑ons.
• The problems are genuinely hard. Connecting AI to automated lab workflows, ML pipelines, and multi‑domain knowledge graphs means inventing patterns, not copying them.
• You’ll learn domains you never expected. Working shoulder‑to‑shoulder with lab scientists and ML engineers means your technical surface area grows fast.
• You’ll ship things that matter. The tools you build accelerate research timelines from months to days.

• Design & Build UI and APIs: Design and build high‑performance, secure, and well‑documented UI and APIs that integrate with AI‑driven applications.
• Database Architecture & Scaling: Develop schemas and manage diverse data systems (SQL, No
  
  SQL, Vector DBs, and others) for optimal performance and scalability.
• Application Development: Drive the implementation of front‑end and backend services, focusing on performance, maintainability, and reliability.
• Performance & Reliability: Diagnose and optimize system bottlenecks, ensuring high availability and low‑latency performance across large‑scale workloads.
• Cloud & Infrastructure: Leverage AWS services, Kubernetes and modern Dev Ops practices to build and deploy production‑grade systems at scale.
• Cross‑Functional
  
  Collaboration:
  
  Work with ML researchers, engineers, and scientists to integrate data pipelines, APIs, and cloud infrastructure into scientific workflows.

• Bachelor’s or Master’s degree in Computer Science, Engineering, or related field.
• 5–8+ years of engineering experience building and deploying large‑scale systems in production. You must be strong in backend.
• Full Stack Development
  :
  Experience developing web apps across the full stack (React, Type Script, Monorepos like Nx, Tail Wind, FastAPI, SQL/No
  
  SQL, Python, Pydantic)
• Hands on experience using AI coding assistants to drive productivity is required.
• Communication & Collaboration
  :
  Acute listening skills, and a proven track record of working cross‑functionally with scientists, data engineers, and product teams; able to explain complex ideas to diverse audiences.
• Problem Solving
  :
  Proven ability to take ownership of complex backend challenges, balancing trade‑offs between scalability, performance, and maintainability.

• Applied AI Engineering: Experience building with AI agents, graph‑based workflows, tool‑use protocols (MCP), RAG pipelines, or LLM orchestration frameworks.
• Cloud & Dev Ops Knowledge: Hands‑on experience with AWS; strong understanding of Kubernetes and containerization, infrastructure‑as‑code (Terraform, Cloud Formation), and CI/CD pipelines (Git Hub Actions).
• Experience with ORMs: Experience with and web services for CRUD services (SQLModel, FastAPI, Django).
• Orchestration Systems: Experience with orchestrators tools (Airflow, Prefect, Temporal, Dagster).
• Familiarity with Python for Science
  :
  Familiarity with data science and ML libraries (pandas, numpy, scipy, jax, pytorch).
• Domain Background: Exposure to laboratory software or analytics for life sciences, material sciences, or related fields.
• Experience with laboratory devices, robotics, or hardware drivers.
