Software Architect, Software Engineer

PDS Defense, Inc. is seeking a Software Engineer III (DSP & Embedded) Software Architect, in Coral Gables Fl.

.000

The Software Engineer III is a senior, architecture-level role responsible for defining and evolving the software architecture of embedded and DSP-based systems used in a commercial aircraft environment. This individual leads technical design decisions across one or more projects, drives architecture and trade-study reviews, ensures compliance with DO-178B/DO-178C processes, and provides technical mentorship to less-experienced engineers. The role combines hands‑on development with architectural ownership, requirements traceability, and cross‑discipline technical leadership.

The essential functions include, but are not limited to:

• Define, document, and maintain the software architecture for avionic equipment, ensuring designs are robust, testable, and consistent with safety and regulatory requirements under DO-178B/DO-178C.
• Lead the design, debug, and documentation of assembly language and high‑level software at the project and system level.
• Conduct architecture reviews, technical assessments, and trade studies; evaluate competing technical solutions and recommend the best path forward.
• Provide technical leadership, guidance, and mentorship to Software Engineer I/II personnel and review their design and code.
• Partner with project engineers, systems engineers, and hardware personnel to determine software/hardware partitioning across one or more ongoing projects.
• Own and drive requirements specification, allocation, and bidirectional traceability for software components.
• Lead the software verification process for architecture and software of own design and that of other engineers; define verification strategy for new components.
• Generate and review architectural and design documentation (e.g., SDD, SAS) in accordance with current GEI procedures and standards.
• Serve as technical point of contact for the isolation, root‑cause analysis, and rectification of complex problems reported by customers following product release.
• Support proposals, technical estimates, and certification activities by providing architectural and technical input.

• Bachelor of Science in Software, Computer, or Electrical Engineering (Master's degree a plus).
• 7+ years of experience in the development, architecture, and maintenance of high‑level and structured assembly language software, including demonstrated ownership of software architecture on at least one DO-178B/C program.
• Demonstrated experience leading technical design decisions and mentoring other engineers
• Minimum 7 years of experience with C/C++ in embedded, real‑time environments, including architecture‑level design experience.
• Strong ability to read schematics, troubleshoot hardware, and guide hardware/software partitioning decisions.
• Solid working knowledge of the DO-178B/DO-178C software development process, including experience producing or reviewing lifecycle data (PSAC, SDD, SAS, SVP).
• Working knowledge of requirements management and modeling tools (e.g., DOORS, CAMEO/Magic Draw, SCADE) a plus.

• Strong familiarity with DSP algorithms (FIR, IIR, Tone Detection) and their application at an architectural level.
• Experience applying DSP techniques to audio processing.
• Familiarity with Audio CODECs and audio signal chains.
• Familiarity with the Analog Devices Inc. family of DSP ICs for embedded applications.
• Experience with DSP software development tools (e.g., Cross Core Embedded Studio).
• Familiarity with avionics data buses and protocols (e.g., ARINC 429, MIL-STD-1553) preferred.
• Experience with real‑time operating systems and time/space partitioning concepts…
