Backend Software Developer (Energy, Time Series & Data Flows)

Enersee is scaling its platform and we’re looking for a backend software developer to build the services, integrations, and data flows that power our energy efficiency product. Your focus is production-grade backend engineering: designing systems that reliably move data from “source → validated → served,” and keep working under real-world conditions.

What you’ll do

Build backend services that run in production

• Design and implement scalable backend services (Python, APIs, internal services).

• Own reliability: monitoring, logging, alerting, performance, debugging, incident follow-up.

• Write clean, testable code and improve existing architecture where needed.

Build and evolve data flows (core)

• Design and implement end-to-end data flows: ingestion → validation → AI analytics → exposure (API/product).

• Ensure data correctness and traceability (versioning, lineage, retries, idempotency, backfills).

• Improve throughput and latency of critical flows; handle spikes and partial …
