Backend Systems Engineer - IOT

About Trillectric We work with real-world energy data from solar systems — helping turn it into reliable signals that power better decisions. We are looking for a backend engineer to help us build robust, scalable systems for ingesting and processing high-frequency data from energy devices. You’ll work on socket-based data streams, ensure device data lands cleanly, and build supporting infrastructure that can scale to thousands of field assets — even under poor connectivity or real-world edge failures. Responsibilities • Build services to handle inbound data from 5,000+ devices over TCP/MQTT. • Maintain uptime and data integrity across varying network conditions. • Normalize and persist telemetry from diverse hardware systems. • Monitor memory, CPU, and disk usage to keep services running predictably. • Write clear, testable backend logic for tracking device-level behavior. You Might Work With • Device streams sending every 30–60 seconds • Low-memory environments (e.g. 5MB RAM limit) • Ingestion limits (e.g. 1 write/sec to disk) • Systems where data delay, duplication, or out-of-order events are common You Should Have • 2–4 years experience building and maintaining backend systems • Hands-on with Node.js, Go, or Python for data-heavy backend services • Familiarity with Redis, MongoDB, or other storage suitable for high-churn data • Experience with TCP socket handling, real-time data ingestion, or device comms • A mindset of building for reliability, not just happy-path development.
