Position: Senior AI Engineer (hybrid)
About Johnson Controls Johnson Controls, a global leader in thermal management, mission-critical building systems, energy efficiency, and decarbonization, helps customers use energy more productively, reduce carbon emissions, and operate with the precision and resilience required in rapidly expanding industries such as data centers, healthcare, pharmaceuticals, advanced manufacturing, and higher education.  For more than 140 years, Johnson Controls has delivered performance where it really matters.

Backed by advanced technology, lifecycle services and an industry-leading field organization, we elevate customer performance, turn goals into real-world results and help move society forward.  Visit  for more information and follow @Johnson controls on social platforms.  What you will do Johnson Controls builds configured air handling units. A consulting engineer's mechanical schedule becomes a selection, a quote, a released BOM, a routing, and a build packet at a station.

Along that path we generate a large amount of structured and semi-structured data — decades of historical orders, configurations, BOMs, labor actuals, test results, quality findings, and service records — and we currently use very little of it to make the next order faster, cheaper, or more accurate. As a Senior AI Engineer, you will set the technical direction for AI at that intersection.

Concretely: reading customer specifications and schedules well enough to propose a configuration, catching a wrong BOM before material is committed, estimating cost and labor for non-standard scope, and putting useful assistance in front of a sales engineer, an application engineer, and an operator on the floor. You will write production code, own architecture, and be the person the organization trusts to say which problems are genuinely AI problems, which are data quality problems wearing an AI costume, and which are better solved with a rule, a query, or a fixed process.

We would rather hire someone with the judgment to challenge a bad idea early than someone eager to ship a demo. Join our team in York, Pennsylvania, where you'll have the opportunity to make an immediate impact. Candidates should be located within commuting distance of the facility or be open to relocating, with relocation assistance available. For the right candidate, we are also open to considering a fully remote work arrangement.

How you will do it Set technical direction Own the AI/ML architecture and technical strategy for sales, engineering, and manufacturing systems — model selection, data architecture, evaluation approach, deployment topology, and build-versus-buy recommendations. Partner with product management, sales operations, engineering leadership, and plant operations to translate business problems into a prioritized portfolio of AI work with honest, expected value and honest feasibility.

Establish the engineering standards this domain requires: reproducible training and evaluation, model and prompt versioning, monitoring and drift detection, rollback paths, and audit trails sufficient for a system that influences what gets built and shipped. Serve as the senior technical voice in design reviews and as a mentor to software and data engineers adopting these techniques. Raise the team's ceiling, not just your own output.

Build the applications Specification and document intelligence. Extract structured requirements from customer specifications, mechanical schedules, and submittal documents — PDFs, drawings, spreadsheets — and map them to candidate configurations and selections. Configuration and quoting assistance. Guided selling and configuration recommendation, competitive crossover matching, pricing and discount guidance, and cost estimation for the…
