Job Description

The Undersea Systems Division (USD) at Leidos is seeking a Software Engineer to join a fast-paced, highly collaborative team developing and rapidly prototyping advanced ocean technologies. In this role, you will work closely with a multidisciplinary group of engineers to design custom software tools, integrate new technologies, and support hands-on testing of mission-critical sensor systems. Our projects span the full development lifecycle—from concept exploration and iterative design to lab evaluation and at-sea demonstrations.

This role is performed fully on-site at NIWC PAC Bayside in San Diego, CA, and follows a 9/80B schedule aligned with customer operations.

Primary Responsibilities

  • Lead the development and maintenance of software tools that support testing and evaluation of mission-critical undersea sensor systems.
  • Collaborate with cross-functional engineering teams to design, integrate, and assess new and emerging sensor technologies.
  • Identify opportunities to adopt and integrate new technologies that improve software development workflows, testing capabilities, and automation.
  • Support laboratory and field testing of deliverable systems, including troubleshooting, validation, and data analysis.
  • Conduct periodic at-sea testing aboard small vessels and assist with post‑processing and interpretation of collected data.

Basic Qualifications

  • U.S. Citizen with the ability to obtain a SECRET security clearance.
  • Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, or related STEM field and 2–4 years of relevant experience; or a Master’s degree with 0–2 years of experience.
  • Professional software development experience with proficiency in C# (.NET Framework).
  • Working knowledge of C/C++ for hardware-focused or embedded applications.
  • Proven experience with multithreading and asynchronous programming.
  • Experience developing software interfaces for hardware such as DAQ systems, sensors, actuators, or custom test equipment.
  • Familiarity with communication protocols including Serial/RS232, I2C, SPI, or Ethernet/TCP-IP.
  • Competence with standard laboratory equipment (oscilloscopes, DMMs, power supplies).
  • A proactive, hands-on troubleshooting approach—comfortable transitioning between IDEs, lab benches, and field environments.
  • Ability to translate complex technical challenges into clear requirements and communicate solutions to both technical and non-technical stakeholders.

Preferred Qualifications

  • Active SECRET security clearance.
  • Experience developing tools for data collection, automation, or system monitoring.
  • Experience with Python and scientific/analysis libraries such as NumPy, SciPy, and Pandas.
  • Experience developing desktop GUI applications (e.g., WPF, WinForms).
  • Familiarity with Git-based version control workflows.
  • Experience using advanced electronic test equipment such as spectrum analyzers and oscilloscopes.

Work Environment & Physical Requirements

While most work is performed in an office or laboratory setting, this role occasionally requires:

  • Working aboard marine vessels in varying weather and temperature conditions.
  • Moving through piers, docks, and industrial facilities, including stooping, kneeling, or reaching for extended periods.
  • Operating tools, instrumentation, and computer equipment using hands and fingers.
  • Lifting or transporting objects weighing up to 50 lbs.
