About The Position

The Sr Advanced Software Engineer will design, develop, integrate, and validate mission-critical embedded software for aerospace applications, supporting Honeywell Aerospace’s next-generation common avionics platform for future cockpit solutions. The role focuses on avionics software engineering, safety and regulatory compliance, and integration across aircraft platforms. The position is based in Phoenix, Arizona, with a hybrid work schedule; relocation is not offered. The engineer will develop embedded applications in C/C++ for deterministic hard real-time operating systems, use Python for scripting and automation, and work with avionics communication protocols and project lifecycle tools. The role also involves requirements engineering and traceability, software assurance and system engineering processes, iterative development, cross-functional collaboration, and technical mentorship.

Requirements

At least 6 years of experience in embedded software development for avionics or safety-critical systems.
Demonstrated proficiency in C++ and Python.
Proficiency with Jira, Bitbucket, Bamboo, Confluence, and IBM Rational DOORS.
Must be a U.S. Person (U.S. citizen, U.S. permanent resident, or a person with protected status under asylum or refugee status) or have the ability to obtain export authorization.

Nice To Haves

Familiarity with DO-178B/C, ARP4754, and safety-critical software development processes.
