Senior Engine Performance Engineer

Caterpillar•Mossville, IL

About The Position

The Power Systems and Controls Development Team within Caterpillar's Large Power Systems Division develops engine systems that deliver performance, emissions compliance, reliability, and customer value across demanding applications. The team works across engine hardware, controls, simulation, test, and data analytics to support New Technology Introduction (NTI) and New Product Introduction (NPI) programs. As a Senior Engine Development Engineer, you will lead engine rating and calibration development for dual-fuel or gas engine programs. You will translate product and customer requirements into development plans, use test and simulation results to optimize engine performance and emissions, and provide technical direction across calibration, controls, hardware, and test activities. The role requires sound engineering judgment, strong analytical capability, and effective collaboration with global, cross-functional teams.

Requirements

Bachelor's degree in an accredited engineering discipline.
Professional experience in engine rating development.
Extensive knowledge of engine performance development, combustion and emissions, calibration methods, engine systems, and controls.
Ability to apply engineering fundamentals and current development practices to significant technical challenges.
Ability to analyze complex system problems, identify inconsistencies in test or simulation data, select appropriate analytical methods, and develop evidence-based recommendations.
Ability to lead structured root-cause investigations, evaluate solutions and risks, drive issues to closure, and capture lessons learned.
Ability to maintain data and calibration quality through disciplined review, cross-checking, traceability, and verification of hardware, software, test setup, and results.
Knowledge of process-improvement tools and techniques, with the ability to improve workflows, standard work, tools, and handoffs.
Ability to communicate complex technical information clearly in reports, reviews, and cross-functional discussions, adapting detail to the audience.
Working knowledge of project management strategies and tactics, including planning and coordinating complex development activities, tracking progress and risks, and balancing program priorities.
Ability to use requirements, data, technical risk, cost, schedule, and customer impact to make or recommend sound system-level decisions.
Knowledge of engineering tools and techniques used to model, analyze, simulate, and test engine system designs.

Nice To Haves

Responsibilities

Develop and optimize engine ratings and calibrations to meet performance, emissions, durability, hardware-protection, and customer requirements.
Translate technical requirements into development and validation plans, including test objectives, instrumentation needs, data requirements, and risk-mitigation actions.
Plan and execute engine development work using test-cell data, simulation results, and engineering analysis; confirm data quality and identify gaps before making decisions.
Evaluate interactions among engine hardware, controls software, combustion, air and fuel systems, and operating limits; recommend balanced system-level solutions.
Support software strategy and hardware-recipe evaluations, including calibration-map development, with production-intent controls.
Lead complex issue investigation and root-cause resolution for engine performance, emissions, calibration, controls, and test-related concerns.
Create technical reports and recommendations; communicate program status, risks, tradeoffs, and decisions to technical and program leadership.
Improve development processes, analysis tools, visualization methods, and standard work to increase quality, repeatability, and program velocity.
Provide technical guidance and mentoring to engineers and partners; coordinate work across test, controls, simulation, design, certification, and application teams.
Manage multiple development priorities while maintaining a commitment to safety, quality, accuracy, and timely delivery.
