Remote Disney Software Engineer Jobs in Iowa (NOW HIRING)

Engineers are the reason we exist-they're the core of who we are. We don't just build technology; we engineer the future. From next-gen aerospace to cutting-edge defense systems, our teams power the solutions that drive innovation, tackle mission-critical challenges, and keep people safe. This is where problem-solvers and big thinkers thrive.

Quest Defense Systems & Solutions is seeking Embedded Software Engineers to build the foundational software components that enable next-generation avionics systems. This team is responsible for developing shared libraries, I/O frameworks, and partitioned services that power multiple avionics applications.

This role is ideal for a systems-minded engineer with deep low-level experience who can design robust, certifiable software architectures. This effort will be in support of multiple key programs, including the Next Gen Flight Management System (FMS) program.

Due to the nature of this role, all candidates must be US Citizens OR US Persons.

Preference is onsite in Cedar Rapids, IA. Will consider remote candidates meeting all requirements.

Key Responsibilities:

• Abstract and consolidate core functions into reusable libraries and frameworks
• Extract existing functionality from application code and refactor for shared use
• Design and implement an I/O framework supporting multiple protocols and data interfaces
• Define and maintain data dictionaries and I/O level specifications
• Collaborate with system architects to ensure ARINC-653 partitioning integrity
• Support certification activities through HLR/LLR documentation and DAL compliance
• Contribute to long-term strategy for scalable, maintainable software infrastructure

Required Qualifications:

• 4+ years of experience in embedded software development and/or testing.
• Proven expertise in C++ and object-oriented design for embedded systems
• Working knowledge of I/O architecture, protocol handling, and data management
• Background in developing certifiable software (DO-178 DAL A preferred)
• Proficiency in HLR/LLR generation, review, and traceability
• Quick learner with strong initiative and drive

Desired Skills:

• Strong experience with ARINC-653 partitioning and low-level application design
• Hands-on experience with VxWorks RTOS
• Familiarity with toolchains and CI/CD environments supporting configuration management and verification (Atlassian Suite, Jama, Coverity, Rapita, etc)
• Designed and implemented non-volatile data storage systems (e.g., EEPROM, flash, or NVRAM) for configuration or state retention
• Experience with persistent and transient log storage, including rollover and data retention policies
• Familiarity with log transport mechanisms (e.g., shared memory, I/O channels, or network-based telemetry)
• Experience developing or integrating ARINC 661 Cockpit Display Systems (CDS) and User Applications (UA)
• Familiarity with avionics data buses and communication protocols (e.g., ARINC-429, MIL-STD-1553, AFDX, CAN, SPI, UART, etc)
• Strategic systems thinker able to plan scalable, reusable frameworks
• Previous FMS Experience is a bonus but not required.
• Experience in the adoption and/or integration of emerging technologies (e.g., generative AI, automation platforms, digital assistants) into day-to-day operations for continuous improvement.

Ideal Candidate:

Technically strong software engineer who can balance deep systems knowledge with strategic foresight. One who understands how to design reusable building blocks for complex, safety-critical systems-and thrives in a fast-moving environment where architecture, certification, and execution come together.
