## Description

This is a backend engineering role on the core infrastructure team of an early-stage energy tech company building the foundational layer for next-generation dynamic electricity plans. You'll work on a modular billing engine, low-level energy-market communication protocols, and a full accounting ledger - systems that need to be both highly reliable and infinitely scalable.
What You'll Do

 * Design systems that tame complexity at the architectural level, not just the code level.
 * Scale core infrastructure to handle dynamic billing, energy trading integrations, and real-time data flows.
 * Take decisive action in ambiguous situations, shipping thoughtful solutions without waiting for perfect information.
 * Continuously raise the quality bar across the codebase, technical processes, and team practices.
