System Software Engineer

>> 360Watts: an energy-tech startup

We are developing an Energy Management mobile-first B2C app that connects solar generation, battery storage, and smart-home appliances into a unified interface — empowering users to monitor, optimise, and automate their energy usage at homes. Our product vision spans from AI-integrated control (phase 1) and will transition to AI-native agents (phase 2).

>> Roles & Responsibilities

We are hiring an experienced Software Lead who will own the overall system architecture, backend development, cloud infrastructure of our solution. You’ll work closely with our IoT, ML, solar, and UI/UX team to bring the product to market.

This is a high-ownership, builder-first role with strong potential to grow into AI-Software Lead.

1) System architecture & Engineering

• Design the end-to-end software architecture for the EMS backend, mobile app services, and data infrastructure
• Define modular components for device integration, data pipelines, ML inference, and real-time user interfaces
• Ensure scalability, security, and maintainability across backend and API layers
• Own architectural decisions as the product evolves from AI-integrated to AI-native agentic application

2) Backend development + Cloud:

• Design, implement and maintain cloud-based backend systems using Python (FastAPI) or Node.js (NestJS preferred)
• Build modular, secure REST APIs for real-time data ingestion, device control, alerts, and AI model integration
• Design time-series data schema and store telemetry data using PostgreSQL/TimescaleDB
• Deploy containerised services (Docker) and CI/CD pipelines to AWS or GCP
• Handle role-based access, API observability, logs, uptime metrics, and system scaling

2) Bonus: Frontend development

• Build or contribute to React Native mobile app (ideal if you have mobile frontend experience)
• Help develop web-based internal tools or dashboards (React/Next.js)

>> Experience & Skillsets required

• 2–4 years experience in full-stack or backend software development
• At least 1 production-ready product or 2-3 MVP delivered to end users — SaaS or mobile app
• Prior role involving system design or architecture for a SaaS/mobile/IoT product
• Experience working in small, fast-moving teams (startup or lean product development teams)
• Proficiency in backend development with Python (FastAPI) or Node.js/NestJS
• Experience designing and managing PostgreSQL databases with telemetry or analytics data
• Experience working in small, fast-moving teams (startup or lean product development teams)
• Familiarity with API versioning, CI/CD, Docker, and cloud deployment (AWS/GCP)
• Exposure to ML model integration (serving endpoints, forecasting APIs, etc.)

>> Job details:

• Location: Coimbatore
• Start Date: 01.12.2025 or 15.12.2025
• Compensation: up to ₹6 LPA (further negotiable based on experience & skillsets)
