Mobile App Software Engineer (Backend/Cloud)

Description

You will lead the development of 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. The product vision spans from AI-integrated control (phase 1) and will transition to AI-native agents (phase 2).

• Design the end-to-end architecture of the Energy Management Software (EMS) such as backend/frontend, data, cloud, and API ecosystem
• Design, implement and maintain cloud-based backend systems using Python (FastAPI) or Node.js (NestJS preferred)
• Prior lead or support role in system design or architecture for a SaaS/mobile/IoT product
• Handle role-based access, API observability, logs, uptime metrics, and system scaling
• Build modular, secure REST APIs for real-time data ingestion, device control, alerts, and AI model integration
• Define modular components for IoT device sync, ML model inference, mobile interfaces, and control logic
• Help develop web-based internal tools or dashboards (React/Next.js)
• Deploy containerised services (Docker) and CI/CD pipelines to AWS or GCP
• Design time-series data schema and store telemetry data using PostgreSQL/TimescaleDB
• Ensure scalability, security, and maintainability across backend and API layers

Requirements

We look for an experienced Software Lead who will own the overall mobile app development incl. architecture, backend, data and cloud infrastructure. You’ll work closely with our IoT, ML and solar engineers, as well as an UI/UX designer to bring the final product to market.

Share your GitHub/portfolio with relevant projects (especially mobile, ML, or API integrations) - highly preferred !!

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

• Build or contribute to React Native mobile app (ideal if you have mobile frontend experience)
• Exposure to ML model integration (serving endpoints, forecasting APIs, etc.)
• Experience working in small, fast-moving teams (startup or lean product development teams)
• Experience designing and managing PostgreSQL databases with telemetry or analytics data
• At least 1 production-ready product or 2-3 MVP delivered to end users — SaaS or mobile app
• 2–3 years experience in full-stack or backend/cloud software development
• Experience in backend development with Python (FastAPI) or Node.js/NestJS
• Experience with API versioning, CI/CD, Docker, and cloud deployment (AWS)
• Own architectural decisions as the product evolves from AI-integrated to AI-native agentic application

Benefits

• Compensation: 4.2 to 6LPA. Further negotiable post 3-month probation period, upon proving with results and developing strong skillsets that are required for the role.
