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 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 formulaeparticularly 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 youll 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 Framework/WinForms/C#/SQL Server desktop applications handling engineering calculations and workflow logic. Refactor and progressively modernize legacy components (e.g. migrate services (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 Energys core values of safety and integrity which means taking responsibility for your own actions while caring for your colleagues and the business.

Your background:

• Bachelors degree in software/electrical/mechanical engineering or related field. Proven full-stack development experience (typically 48 years) delivering production web applications.

• C# .NET / Core Web API; experience migrating Framework to preferred. Proficiency with at least one modern framework (React Angular or Vue) TypeScript HTML5 CSS3.

• SQL Server (TSQL schema design stored procedures performance tuning). Strong hands-on with WinForms C# .NET Framework 4.x and .

• 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. 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.

• Proficiency in both spoken & written English language is required.
