Pratt & Whitney is working to once again transform the future of flight—designing, building and servicing engines unlike any the world has ever seen. And because transformation begins from within, we’re seeking the people to drive it. So, calling all curious. 

Come ready to explore and you’ll find a place where your talent takes flight—beyond the borders of title, a country or your comfort zone. Bring your passion and commitment and we’ll welcome you into a tight-knit team that takes our mission personally. Channel your drive to make a difference into shaping an organization and an industry that’s evolving fast to the future.

At Pratt & Whitney, the difference you make is on display every day. Just look up. Are you ready to go beyond?

We have an exciting new remote opportunity with our Digital Technology (DT) Digital Manufacturing Applications team for a Senior C# OpCenter Developer.

What You Will Do:

We are seeking a Senior MES Developer who will own the design and delivery of customizations and extensions within the Opcenter layer, architect and harden the Teamcenter ↔ Opcenter integration, and serve as the senior technical anchor for our offshore development team.

This is a hands‑on engineering role with technical leadership responsibilities: you will establish coding standards, conduct code reviews, mentor developers in India, and manage the CI/CD pipeline for all MES customizations.

A key technical challenge in this role involves the propagation of engineering changes from the PLM layer into live MES work orders—ensuring that the shop floor always builds to the latest released definition.

This requires designing integrations that are efficient, event‑driven, resilient, and lean on network traffic, avoiding heavy reliance on bulk re‑publishing of large data structures.

In this position, you will contribute to back‑end and web‑based development, troubleshoot MES‑related issues, resolve systems integration and compatibility concerns, and support our Application Lifecycle Management Center of Excellence.

This is a remote role, and because our customers operate across multiple time zones, some meetings may occur outside standard business hours.

Key Responsibilities:

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.

What You Will Learn:

Career growth opportunities include access and exposure to technical and functional experts, business operations, and to leadership/executives. This position offers an opportunity to network with technical professionals and to build relationships within the organization being on the front lines of developing technology. 
 

Qualifications You Must Have:

- 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.

 

Qualifications We Prefer:

- Direct experience with Teamcenter and the Opcenter–Teamcenter integration (e.g., Opcenter Connect / CN4T, Active Integration Gateway, Connect MOM).
Working knowledge of the EBOM → MBOM → BOP → work-instruction digital thread and PLM change management (ECR/ECO/ECN).

- Aerospace & Defense or other regulated manufacturing background; familiarity with AS9100 and ITAR/EAR.

- Exposure to MRO / overhaul execution as well as new-make production.
Shop-floor / OT integration awareness (OPC UA, Automation Gateway) and ISA-95 / Purdue model concepts.

- Front-end skills that support model-driven UI work (HTML5, CSS3, JavaScript; Angular).

- Containerization / cloud deployment experience and infrastructure-as-code.
