General program information and/or position overview:
The Undersea Systems Division at Leidos currently has an opening for a Senior Software Engineer in San Diego, CA. Candidate will join a fast-paced engineering group rapid-prototyping a variety of ocean systems. Collaborate across our medium-sized team holding complete technical responsibility for custom development and prototyping across many technical disciplines. Team prototyping efforts span from real-world problem-solving, all the way through concept development, followed by iterative design and testing, and conclude with product demonstrations. Ideal candidates will bring deep experience in firmware and software design and design processes.
This position will require the candidate to work a 9/80B schedule (80 hours of work into nine days over a two-week period, allowing for every other Friday off) to align with the NIWC government team.
Primary Responsibilities:
• Direct the architecture, development, and sustainment of mission-critical sensor recording systems across up to several concurrent projects
Collaborate with team to identify embedded firmware and software requirements and evaluate candidate design approaches for solving wide-ranging technical problems.
• Review the current state of the recording system codebase, including any changes made since my departure, to assess what needs attention and prioritize next steps.
• Identify and resolve any existing code quality issues to establish a stable baseline for ongoing development.
• Begin setting up the recording system build in a CI pipeline to enable automated builds and reduce manual integration risk.
• Begin active development on the recording system, picking up priority tasks based on current project needs.
• Provide technical guidance to the development team on the recording system architecture and best practices.
Basic Qualifications
• U.S. Citizen with Active SECRET security clearance.
• Master’s (or higher) degree from an accredited institution in Computer Science, Computer Engineering, Electrical Engineering, or another STEM field.
• 3+ years of experience in development and integration for one or more of the listed platforms:
o Linux kernel and OS (Yocto, Buildroot) embedded microprocessor firmware and software
o Embedded systems firmware and software
o Docker/Podman, GitLab CI, Git, Google Test, ZMQ, Socket Programming, Multi-threading, Encryption
• Proficiency in the C/C++ programming language.
• Working knowledge of common embedded communications protocols (SPI, RS-232, Ethernet, etc.).
• Working knowledge of software development processes (static analysis, build automation, etc.).
• Familiarity with embedded electronics test equipment (power supplies, oscilloscopes, debuggers).
• Ability to read, understand, and interpret complex technical documents.
• Ability to communicate complex ideas orally and visually.
Preferred Qualifications
• 12+ years of experience in development for one or more of the listed applications:
o OpenCV (or similar) computer vision algorithms
o Digital Signal Processing (DSP), digital filtering, or other mathematical algorithms
o Robotics control system modeling and simulation
• Proficiency in Linux command line tools (grep, etc.) and with Linux shell scripting (Bash, etc.).
• Proficiency in embedded development IDEs and tools (Microchip MPLAB, GCC, GNU Make, etc.).
• Proficiency in software version control processes (Subversion, Git, etc.).
