Sr Advanced Systems Engineer

Join a team that designs, develops, and integrates advanced APU (Auxiliary Power Unit) control systems for Honeywell Aerospace. In this role, you will contribute to the definition, decomposition, validation, and verification of system requirements across the full product lifecycle. You will collaborate with multidisciplinary teams to deliver high-integrity solutions for gas turbine engine applications.

As a Senior Advanced Systems Engineer, you will be a key technical contributor responsible for requirements-based engineering of APU control system functions and components. You will work hands-on on requirements generation, system architecture support, interface definition, and V&V activities while collaborating closely with technical leads and project engineering.

You will operate across the APU Control Systems organization—part of the Engines & Power Systems business—to support program execution, ensure technical rigor, and help meet customer and business milestones.

You will report directly to our Systems Engineering Manager, and you’ll work out of our Phoenix, AZ on a hybrid work schedule. Will be required to work on-site full time for the first 90 days
