Product Engineer

Lumen Energy

36d • Remote

About The Position

We're looking for a Product Engineer who lives at the intersection of product and engineering. This is a high-impact role: you'll wear both product and engineering hats, driving features end-to-end from idea, through rapid prototyping, to polished production experiences. You'll shape what we build and why, not just how. You'll report directly to our Head of Engineering and work cross-functionally with our entire team. This is a full-time, remote (US) role, with an SF office if you'd like one.

Requirements

• Proven track record of execution. You have 3–5+ years of experience in a product engineering, frontend, full-stack, or design engineering role
• Enough production experience to have real opinions about frontend architecture and tooling — you've seen good and bad in the wild and can tell the difference.
• Familiarity with our tech stack (or strong ability to learn new technologies quickly). Our current tech stack is Python, Flask, SQLAlchemy, PostgreSQL, Rust, TypeScript, React, GraphQL, Google Cloud Platform
• Demonstrated use of AI coding tools (Cursor, Claude, Codex, etc.) as a core part of your development workflow

Nice To Haves

• Experience in a startup or high-growth environment
• Background or genuine interest in climate tech or real estate

Responsibilities

• Drive product iteration and execution. Work with partners across Marketing, Sales, and Operations to identify product gaps, then carry solutions through conception, implementation, and maintenance
• Prototype rapidly with AI tools. Get tangible, testable experiences in front of customers and teammates early, and use their feedback to decide what deserves further investment
• Build and ship features end to end, from early prototype through production-ready code

Benefits

• Competitive salary, benefits, and equity participation
• A culture that embraces technology, including AI. We use new tools actively and encourage you to do the same
• Room to grow. We promote from within and invest in the development of our team
