We simplify energy management, so businesses can focus on everything else

Arcadia is the energy intelligence platform for businesses. One place to pay utility bills, buy energy, and advance sustainability — so teams can stop chasing data and start saving money.

We are seeking a Staff Software Engineer to design and implement an end-to-end feature addition to a production Java API and calculation engine, working closely with Arcadia’s engineering leads, product managers, and subject matter experts.

This role requires independence, sound judgment, and demonstrated experience driving technical delivery within an existing production system — not purely greenfield work.
