Full-Stack Product Engineer, Production Monitoring

Position: Full-Stack Product Engineer, Production Monitoring Reports to: Head of Engineering / CEO Works with: Lead Developer (MetisEI Production Monitoring) Location: Pune, India Type: Full-time, permanent Experience: 4+ years commercial software engineering Purpose of the role: To take ownership of defined modules within MetisEI Production Monitoring so that development runs in parallel rather than through a single engineer. Each hire will own a bounded module end-to-end schema, API, and user interface working to agreed interface contracts with the rest of the platform. Key responsibilities: Design and maintain relational schemas in Azure Database for PostgreSQL, extending the existing process node data model. Build and maintain REST APIs serving live production data output, cycle counts, downtime, scrap, rework, labour utilisation. Build front-end interfaces used daily by line leaders, plant management and group functions. These must be usable on a phone, on a shop floor, by a non-technical user. Implement downtime and stoppage logging, threshold alerting, and escalation logic. Consume machine data ingested via Azure IoT Hub and reconcile it against manually captured production data. Write automated tests for all business logic. Any calculation that drives a bonus, a KPI or a management decision must be covered by tests. Document schemas, interfaces and architectural decisions as work is completed not retrospectively. Support multi-site rollout across four countries, including timezone, language and shift-pattern differences. Essential requirements: 4+ years building and shipping production systems that real users depend on daily. Prototype and demo experience alone is not sufficient. Strong relational database design normalisation, indexing, query performance, migrations. PostgreSQL preferred. Backend development in Python and/or Node.js, with REST API design experience. Front-end development in React (or equivalent modern framework), including responsive/mobile layouts. Cloud platform experience Azure strongly preferred, AWS or GCP considered. Disciplined use of version control, branching and code review. Demonstrable habit of writing tests and documentation. This is a hard requirement, not a preference. Written and spoken English sufficient to work with colleagues in the UK, Mexico and China. Desirable: Manufacturing, MES, OEE or industrial systems exposure. Time-series data at volume. IoT / MQTT / Azure IoT Hub. Multi-tenant or multi-site software architecture. Spanish (useful for the Mexico plant, not required). What we are not looking for Engineers who work fast by working alone. Single-point-of-failure development is explicitly what this hire exists to remove. Anyone unwilling to document their work or hand it over. .
