• Collaborate and communicate clearly with engineers, product, and other stakeholders to ensure alignment and effective execution.

• Build and scale forward-looking AI-driven platforms that support and accelerate scientific discovery.

• Look for leverage by automating, abstracting, and improving systems so the team moves faster over time.

Requirements

• Minimum 5 years of full-stack production experience with modern web technologies such as React, Next.js, Node.js, PHP, or Python, and MySQL or Postgres (or similar technologies).

• Solid understanding of architecture, scalability, and performance.

• Experience integrating AI APIs and intelligent workflows into real applications.

• Demonstrated initiative, with experience leading and delivering small to large projects end to end.

• High ownership, high output, and strong attention to code quality.

• Strong coding skills, with an emphasis on building understandable and maintainable software while collaborating effectively with others.

• Strong communication skills, both written and verbal, evident in the quality of technical specifications, discourse, and feedback.

• Curious, adaptable, and motivated to continuously improve.

Why Join Us

Our engineering culture is built on a simple belief: a small, talented team operating efficiently can build exceptional software without working 65-hour weeks.

We believe engineers do their best work when they have space to think, autonomy to make decisions, and clarity of purpose. We create an environment that supports focus, ownership, and a sustainable pace.

We do this through:

• No micromanagement. Engineers own decisions and outcomes.

• Natural collaboration and deliberate communication.

• Investing in tools and abstractions that provide leverage.
