Job description

Lead Full Stack Engineer San Francisco $185k-$210k + Equity

I’m working with a small, Y Combinator-backed technology company in San Francisco looking for a genuinely strong Full Stack Engineer to take ownership of its core software platform.

The business is building a data and analytics platform for agriculture, processing large amounts of operational data to help farmers make better decisions.

They’re particularly interested in engineers from strong engineering environments such as Google, SpaceX or similar, who also have the independence and curiosity to build products from 0 to 1.

This is a hands-on role with significant technical ownership, working directly with the founders.

The Role

You’ll be responsible for:

  • Building production backend systems using Python.
  • Developing frontend applications using JavaScript/React.
  • Designing and optimising PostgreSQL databases.
  • Building automated data pipelines and processing complex datasets.
  • Owning cloud infrastructure, CI/CD and production reliability.
  • Making architecture decisions and shipping features end-to-end.
  • Helping shape the technical direction as the company grows.

Requirements

Software Engineering, Storage Area Network (SAN), Agriculture, Data Analysis, Product Development, Python Programming/Scripting Language, Production Systems, User Interface/Experience (UI/UX), Software Development, React.js, * 6+ years of software engineering experience.

  • Strong full-stack ability across Python and JavaScript.
  • Deep understanding of databases, data pipelines and infrastructure.
  • Experience building and shipping products from 0 to 1.
  • Strong engineering fundamentals, ideally from a technically demanding organisation.
  • Someone genuinely curious, independent and comfortable working without constant direction.
  • Previous Founding Engineer or early-stage startup experience would be particularly interesting.
  • Practical experience using AI development tools such as Cursor or Claude.

Agriculture experience isn’t required. They’re far more interested in strong engineering ability and someone who enjoys solving difficult problems.
