Location: Chennai, Tamil Nadu, India Job ID: R0118027 Date Posted: 2026-03-16 Company Name: HITACHI ENERGY TECHNOLOGY SERVICES PRIVATE LIMITED Profession (Job Category): IT, Telecom & Internet Job Schedule: Full time Remote: No Job Description: The opportunity: The Software Engineer – Full Stack Developer – I&C Platform will design, build, and maintain modern, web-based applications for the I&C platform using the latest software technologies, while sustaining and modernizing legacy desktop applications built on .NET Framework, WinForms, C#, and SQL Server. This role will also develop interactive applications on the PTC Thing Worx platform by translating engineering business logic and formulae—particularly those related to Transformer components (Bushing, Tap-Changer, and related assemblies)—into robust, intuitive, and validated web experiences. The developer will work independently to deliver end-to-end features, integrations, and visualizations (graphs/simulations), ensuring performance, quality, and reliability across the application portfolio. How you’ll make an impact: Design and implement scalable full-stack features (front-end, APIs, database) using modern web technologies. Build responsive, intuitive UIs for engineering workflows and results visualization (charts/plots). Maintain and enhance .NET Framework/WinForms/C#/SQL Server desktop applications handling engineering calculations and workflow logic. Refactor and progressively modernize legacy components (e.g., migrate services to .NET (Core/6/8), expose APIs, prepare for web adoption). Develop Thing Worx artifacts (Things, Thing Templates, Mashups, Services, Data Shapes, Data Tables) to convert business logic into interactive web applications. Integrate Thing Worx with enterprise data sources and external services via REST APIs/MuleSoft/middleware. Translate engineering formulae and rules (e.g., for Transformer Bushing design, Tap-Changer configuration) into validated, unit-tested code. Implement numerical computations and visualize outputs as graphs/plots (e.g., parameter sweeps, performance curves, tolerancing). Ensure unit consistency, precision handling, and edge-case coverage for calculation accuracy. Design efficient SQL Server schemas, queries, and stored procedures; optimize performance (indexing, query tuning). Build and consume REST/SOAP APIs; implement integrations via MuleSoft or equivalent middleware (authentication, mapping, error handling, retries, monitoring). Write clean, testable code with unit/integration tests; perform code reviews and follow secure coding standards (OWASP). Use Git-based workflows and CI/CD (e.g., Azure DevOps/GitHub Actions) for automated build/test/deploy; contribute to automated pipelines. Monitor, troubleshoot, and optimize performance across the stack; log/trace issues effectively. Work closely with I&C platform engineers, electrical/mechanical SMEs, and product owners to refine requirements and acceptance criteria. Produce technical documentation (designs, API specs, data contracts, calculation notes/assumptions, validation results). Operate independently, manage priorities, and deliver increments on time with high quality. Responsible to ensure compliance with applicable external and internal regulations, procedures, and guidelines. Living Hitachi Energy’s core values of safety and integrity, which means taking responsibility for your own actions while caring for your colleagues and the business. Your background: Bachelor’s degree in software/electrical/mechanical engineering, or related field. Proven full-stack development experience (typically 4–8+ years) delivering production web applications. C#, .NET / ASP.NET Core, Web API; experience migrating from .NET Framework to modern .NET preferred. Proficiency with at least one modern framework (React, Angular, or Vue), TypeScript, HTML5, CSS3. SQL Server (T‑SQL, schema design, stored procedures, performance tuning). Strong hands-on with WinForms, C#, .NET Framework 4.x, and ADO.NET. Experience building Mashups, Thing Templates, Services (JavaScript), Data Shapes/Tables, and using Thing Worx REST APIs. Ability to implement engineering plots using charting libraries (e.g., Chart.js, D3.js, Plotly) or Thing Worx widgets. Building/consuming REST/SOAP; enterprise integration via MuleSoft or similar middleware (mapping, transformations, policies). Unit/integration testing (e.g., xUnit/NUnit/Jest), code review, static analysis, and defect triage. Git, branching strategies, CI/CD pipelines (Azure DevOps/GitHub Actions), environment configuration, and release management. Familiarity with OWASP practices, secrets management, and exception/logging frameworks. Understanding transformer engineering or the energy sector within the electrical domain. Self-starter capable of independent execution across analysis, design, implementation, testing, and deployment. Experience with message queues or event-driven patterns; exposure to Thing Worx Edge SDK. Familiarity with Azure services (App Service, Functions, API Management) or equivalent cloud platforms.
