Job description

At Sustainable Energy Inc, the Data Analyst owns the problem end to end, from the first Presentation Skills prototype to the 3 a.m. pager that never rings.

• Implement secure authentication and authorization flows using Generative AI
• Trace an impact-driven technology bug across three Large Language Models services to the one bad line
• Pair with cross-functional partners to scope and deliver temporary projects
• Ensure code quality through automated linting, testing, and static analysis

• The kind of ownership that treats the company's money like your own
• Curiosity and a continuous drive to sharpen your technology craft
• Reliable, accountable, and committed to following through
• The kind of curiosity that reads the docs before asking

Beginning at $142,000 - $212,000, your growth is mentored, your benefits are full, and your hours flex to match life in Princeton, NJ.

We are prioritizing Presentation Skills talent right now and reviewing resumes as they arrive.
