• Desire to ship and maintain production software in a fast‑moving product environment.
• Demonstrated experience working with a small team, preferably in start‑ups.
• Strong object‑oriented fundamentals applied to complex, evolving production codebases.
• Strong communication skills and a collaborative approach to working across product and engineering teams.

• Industry experience in renewable energy, utilities, heat pump technology, or construction.
• A background in product‑focused engineering environments.
