Top Tech Jobs & Startup Jobs in Chicago, IL

Design, architect, test, and demonstrate Windchill and ThingWorx solutions for DoD customers. Translate business requirements into technical/process solutions, support integrations, perform testing and debugging, develop documentation, provide end-user training, and collaborate with cross-functional teams and PTC support to deliver PLM/ThingWorx implementations.

Develop and evolve government reference architectures for autonomous, mission-critical systems. Translate operational concepts into SysML/UML behavioral models, interface specifications, and traceable requirements. Define interfaces and integration approaches, support MBSE/digital engineering, collaborate with engineers and operators, and participate in architecture and design reviews.

Improve, modernize, and sustain complex, distributed defense software by debugging production issues, performing root-cause analysis, refactoring legacy code, reducing technical debt, enhancing CI/CD and automated testing, and collaborating with engineers, architects, and government stakeholders to maintain performance, interoperability, and delivery schedules.

Develop, test, and maintain production-quality C++ software implementing Government Reference Architectures for mission-critical defense systems. Translate MBSE (SysML/Cameo) artifacts into interoperable components, implement APIs/ICDs, integrate distributed messaging frameworks (ActiveMQ/DDS/ZeroMQ), and maintain CI/CD, automated testing, containerized builds, and static analysis. Collaborate with systems engineers, architects, autonomy engineers, and government stakeholders to validate interoperability and performance.

Drive technical sales of digital engineering solutions to DoD and defense industry customers: demonstrate MBSE/Cameo tooling, consult on model-to-artifact automation, support proposals and RFIs/RFPs, engage acquisition stakeholders, and enable integration into CI/CD workflows while maintaining security compliance.

Develop and integrate open-architecture, standards-based software for defense and aerospace systems. Implement and map interoperability standards (SOSA, FACE, AMS GRA, UCI), work with serialization formats (OMG IDL, protobuf, XSD, XMI), perform structural and semantic gap analysis, support interface/data model transformations, collaborate with multidisciplinary teams, produce documentation and interface specifications, and participate in architecture and design reviews.

Develop systems software to parse, reverse-engineer, and deterministically generate complex engineering data. Build tooling for schema translation, compiler/transpiler solutions, reproducible CI/CD pipelines, and automated document generation. Collaborate with multidisciplinary teams, support verification/validation, and apply MBSE concepts for engineering integration.

Design and implement NLP and LLM-powered pipelines to extract, summarize, and semantically search technical documentation. Fine-tune transformer models, build RAG systems, convert unstructured documents into structured knowledge, optimize inference for production, and collaborate with engineers and SMEs to deploy document intelligence solutions.

The Windchill Application Developer will develop, implement, test, and maintain Windchill solutions, collaborate with teams, and troubleshoot application issues for the US Navy.

The Windchill Infrastructure & System Administrator maintains Windchill systems, manages AWS infrastructure, handles installations and upgrades, collaborates with teams, and ensures performance and security of the systems.
