Neufin is a tech-led energy retailer delivering clean, low-cost and flexible energy to India's mid-market Commercial & Industrial businesses.
Our energy software, Lumen, helps businesses track, pay, and optimise their electricity costs (₹/kWh). By integrating real-time IoT data with predictive AI, we enable lower power costs and easier compliance with clean energy targets.
You will be responsible for building the data pipelines and user-facing features for Lumen. You will work to ensure that high-frequency IoT data is processed efficiently and can be visualised intuitively. You will work across different technologies - Solar inveters, BESS, optimisers, smart energy meters, IoT sensors and more.
Develop end-to-end features, from React-based dashboards to backend Python/Node services that process energy consumption data.
Work on data pipelines that ingest real-time telemetry from IoT devices, ensuring low-latency updates for our digital twin models.
Design and implement data visualisations (load curves, consumption insights, and cost charts) that make energy data easy to understand.
Write clean, documented, and testable code while participating in code reviews and maintaining CI/CD standards.
Architect LLM-ready databases and code by prioritising strong typing, modular design, and comprehensive technical documentation. You will ensure our internal AI agents and development tools (like Cursor or Claude Code) have the high-fidelity context required to assist in building, refactoring, and maintaining our energy-tech stack at high velocity.
Partner with the Product team to design, build, and iterate on MVPs for experimental features. You are expected to move quickly from proof-of-concept to production-ready experiments/ideas.
2–3 years of professional software development experience, ideally within a high-growth startup or an IoT/Energy-tech environment.
Full-Stack Proficiency:
Backend: Proficiency in Python (FastAPI/Django) or Node.js. Experience building and consuming RESTful APIs.
Frontend: Expertise in React.js (preferred), Next.js, and TypeScript.
Familiarity with handling time-series data (e.g., InfluxDB, TimescaleDB, Kafka) and understanding of IoT protocols (MQTT or HTTP) is a significant plus.
Hands-on experience with GCP (Cloud Run, Kubernetes, Cloud SQL, BigQuery) and Docker.
You have used AI tools in your workflow in the past and can build on top of existing AI coding platforms.
Experience designing schemas for high-volume data.
You want to understand how a power grid works and how data can solve the climate crisis.
You thrive in a 0-to-1 environment and prefer shipping over over-engineering.
You enjoy working across functions—talking to product managers about UX and to field engineers about hardware maintenance.
Have prior experience in BESS systems, EV BMS systems or Renewable Energy tech startups.
Have built real-time monitoring dashboards for hardware assets.
🪙 Highly competitive salaries, including attractive stock options.
🛡️ Comprehensive health insurance for you and your spouse.
📕 A yearly learning allowance to master new technologies.
🏃♀️ A yearly wellness allowance for physical and mental health.
