What you will do

CSPS builds productivity tools for chiller design teams. Our latest release, the Baffled Condenser Vessel Designer, takes engineering inputs (size, shape, clearances and more) and generates a condenser tube layout and its geometry data from standard design rules.

Johnson Controls is seeking a Senior Design Automation Engineer!Today, geometry data is fed into a design server that automatically generates CAD models and drawings through custom scripting. Together, these tools save more than 100 hours of design time. The next step is extending this approach across additional stages of the chiller design process, enabling teams to iterate faster, improve consistency, and deliver results more efficiently.

This position can be remote for anyone based in the US.

How you will do it

Assess needs and define requirements

• Work with design engineers to map current design processes and find bottlenecks, rework and manual steps worth automating.

• Turn those findings into clear requirements, scope and success measures for new tools.

• Prioritize opportunities by hours saved, error reduction, and effort to build.

Build and deliver design tools

• Work with the CSPS development team to plan, design and implement new design tools and extend existing ones, such as the Baffled Condenser Vessel Designer.

• Develop calculation methods that connect engineering inputs to geometry data.

• Work with the team to develop Creo automation scripts that generate CAD geometry from design inputs, whether by delegating to developers, writing scripts directly, or using AI-assisted coding tools.

• Test tools against real design cases and support engineers through rollout and adoption.

Codify design rules and standards

• Analyze historical design data to extract design rules, standard configurations and best practices.

• Document rules and standards so they can be reviewed by engineering and encoded in tools.

• Keep rule sets current as products and standards change.

Develop engineering calculations

• Develop and validate engineering calculations needed by design tools, such as geometry, clearances and sizing.

• Verify calculation results against existing methods and get sign-off from engineering owners.

Bring AI into the design process

• Identify where AI and machine learning can help, such as suggesting starting designs, checking outputs against standards or searching past designs.

• Prototype and evaluate AI approaches and move the ones that prove out into production tools.

What you will need

Required

• Bachelor’s degree in engineering; Mechanical Engineering preferred.

• 5+ years of engineering experience in product design, manufacturing or a related field.

• Ability to read and evaluate engineering drawings, design processes and calculations, and suggest practical improvements.

• Some hands-on programming or scripting experience, such as Python scripts or CAD automation.

• Strong communication skills for gathering requirements from engineers and explaining technical tradeoffs to both engineers and developers.

Preferred

• Experience with HVAC, chillers, heat exchangers or pressure vessel design.

• Software development experience beyond scripting: version control (Git), testing, and working in a team codebase.

• Web application development experience with Angular and TypeScript.

• Experience with PTC Creo, including Creo automation (for example, Creo Toolkit, J-Link/Object TOOLKIT or Pro/PROGRAM), or working with rules-based or generative design.

• Experience working with engineering data: cleaning, analyzing and finding patterns in historical design records.

• Hands-on use of AI tools in an engineering setting, such as using large language models or AI coding assistants to write scripts, analyze design data, check calculations or speed up design tasks.

• Experience gathering requirements or acting as the link between users and a development team.
