About Merlin:

Merlin (NASDAQ: MRLN) is a publicly traded aerospace and defense company building a non-human pilot to deliver full-stack autonomy for any aircraft from takeoff to touchdown. The Merlin Pilot autonomy system powers a growing range of aircraft and mission profiles and has been proven through hundreds of autonomous flights from Merlin's global flight test facilities, including Kerikeri, New Zealand;
Quonset Point, Rhode Island; and soon, Bedford, Massachusetts. Headquartered in Boston, Merlin is expanding its organization to accelerate the development and deployment of its autonomy platform, helping customers solve some of aviation's most pressing challenges, from pilot shortages to improving flight safety. Backed by some of the world's leading investors prior to its public listing, Merlin continues to advance the certification and commercialization of autonomous flight across commercial and defense aviation.

We are seeking a Staff Software Engineer to design, implement, test, and certify flight-critical autonomy algorithms for next-generation aerospace systems. In this role, you will develop model-based flight software using Math Works tools and support the full lifecycle of DO-178C compliant development.

• Design and develop flight-critical software using Simulink, Stateflow, and related Math Works tools for model-based design.
• Define software architecture, modeling standards, and development workflows aligned with DO-178C and DO-331.
• Create, maintain and review software requirements, models and auto-generated code.
• Ensure robustness and traceability through requirements-based design, verification, and certification artifact production.
• Collaborate with engineers from cross functional groups such as systems, safety, hardware, flight controls, and flight test to ensure product and program level needs are met.
• Support integration into CI pipelines, including model checks, code generation, static analysis, and automated verification.
• Contribute to planning and execution of SOI audits and certification reviews.
• Create and maintain comprehensive documentation for software requirements, architecture and design decisions
• Support hardware-in-the-loop (HIL), processor-in-the-loop (PIL), and flight testing activities.

• Bachelor’s or Master’s degree in Electrical Engineering, Aerospace Engineering, Computer Engineering, Computer Science, or related fields.
