Job Summary: We are seeking a Senior Analyst Developer for functional analysis, backend development with .NET/C#, and HMIs in React, with OT/IT integration and observability. Key Highlights: 1. Detailed functional analysis and requirements specification. 2. Backend development and industrialization using .NET/C# microservices. 3. Robust integration between Operational Technology (OT) and Information Technology (IT). We are looking for a Senior Analyst Developer to join our team in Beriáin. Main responsibilities include detailed functional analysis and requirements specification for an industrial system operating continuously, covering workflows, states, error handling, recovery, and acceptance criteria. You will be responsible for backend development and industrialization using a microservice architecture with .NET/C#, managing orchestration of "recipes", versioning, auditing, and state and exception control. You will also consolidate the core storage layer in PostgreSQL, including domain modeling, integrity, transactions, concurrency, traceability, and controlled migrations. HMIs will be developed in React in kiosk mode, for both end users and professionals, connected to the backend, with a focus on industrial user experience—including actionable errors, retries, timeouts, and system status visualization. Robust integration between Operational Technology (OT) and Information Technology (IT) using PLCs (Beckhoff ADS) will be critical, defining integration contracts, confirmations, timeouts, and validations in controlled environments such as HIL/Sandbox. Operational observability will be implemented via logs, metrics, and dashboards to facilitate diagnostics and reduce mean time to resolution (MTTR). Finally, you will provide technical coordination and quality control of third-party deliverables, reviewing pull requests (PRs) and ensuring knowledge transfer. Working hours are Monday to Friday, from 08:30 to 17:30, full-time. **Professional Experience:** More than 5 years **Education:** Bachelor’s degree in Computer Engineering, Telecommunications Engineering, or another equivalent STEM qualification. * Demonstrable experience in software product development oriented toward 24/7 operations and industrial environments. * Functional analysis capability (user stories, acceptance criteria, coordination with control/mechatronics teams). * On-site work at our office in Beriáin (Navarra).
