About the role

Key responsibilities & impact

MES Customization & Development : Design and build Opcenter customizations and extensions across the data model, Functional Blocks, Signal Rules, Business Process Flows, Task Types and model-driven UI, following the platform’s adaptable-solution principles (keeping the core clean and isolating customer-specific extensions).
Develop operator-facing experiences in Mendix (microflows, nanoflows, custom widgets, mashups) and deeper server-side logic in C# / .NET where low-code is not the right tool.
Translate manufacturing and MRO requirements into robust, upgrade-safe configuration and code that survives Opcenter version uplifts.
Teamcenter ↔ Opcenter Integration : Own the PLM–MES integration layer between Teamcenter and Opcenter — the flow of mBOM, BOP, and work-instruction content into executable work orders. Design change-driven, incremental synchronization so that released engineering changes (ECO/ECN) propagate into affected work orders as minimal deltas, honoring effectivity, rather than full structure re-publishes.
Architect for minimum network traffic and latency using event subscriptions / publish-subscribe patterns, message buffering and guaranteed delivery, REST/OData interfaces, and selective payloads — avoiding chatty polling and redundant transfers across sites.
Define the contract and failure modes of the integration: idempotency, replay, ordering, conflict handling, and observability so issues are caught before they reach the floor.
Technical Leadership, Mentoring & Code Review : Mentor and technically lead the India development team — raising capability in Opcenter, Mendix, and .NET through pairing, design guidance, and structured feedback.
Own code review for all MES customizations: enforce standards for quality, maintainability, security, upgrade-safety, and performance.
Establish and maintain development standards — coding conventions, branching strategy, definition of done, and reusable patterns / shared components.
CI/CD, DevOps & Release Management : Own the CI/CD pipeline for MES customizations — source control, automated build, packaging, and promotion across DEV → TEST → QA → PROD.
Automate and de-risk deployments of Opcenter model/config artifacts and Mendix apps, with versioning, rollback, and environment parity.
Build automated testing and quality gates into the pipeline; integrate static analysis and review checkpoints.
Governance, Quality & Collaboration : Partner with PLM, manufacturing engineering and shop-floor stakeholders to validate that the digital thread behaves correctly end-to-end.
Uphold regulatory and security requirements — AS9100, export control (ITAR/EAR), and platform/network segmentation expectations (e.g., Purdue model) in everything that is built and deployed.
Document architecture and decisions and communicate clearly to both technical peers and non-technical leadership.

Requirements

What you’ll need

Bachelors degree in Computer Science, MIS, Engineering or related degree with 10+ years of prior relevant work experience; OR an Advanced Degree with 7+ years of prior relevant work experience.
Hands-on Siemens Opcenter Execution experience — building customizations/extensions in its model-driven environment (data model, Functional Blocks / POM, Signal Rules, Business Process Flows, model-driven UI). (Camstar / Opcenter Execution Core lineage is relevant.).
Proficiency in Mendix — building and extending low-code applications (Studio Pro, microflows/nanoflows, custom widgets), ideally in an Opcenter / manufacturing context.
Strong C# / .NET engineering skills — server-side extension logic, integration services, and familiarity with the Microsoft / Visual Studio toolchain; Entity Framework and OData/REST.
Demonstrated systems-integration experience between enterprise systems via REST/OData (and ideally event/message-based patterns), with a clear grasp of incremental/delta synchronization and effectivity.
Proven CI/CD ownership — Git-based source control, automated build/test/deploy pipelines (e.g., Azure DevOps, GitLab CI, Jenkins, or similar), versioning and rollback.
Technical leadership experience — mentoring developers, running code reviews, and setting engineering standards, ideally across a distributed/offshore team.
Excellent communication — able to align with non-technical operations and executive stakeholders as well as deep technical peers.
