Software Engineer

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) onsite at NIWC to align with the NIWC government team.

Primary Responsibilities:

This individual will work with a small team of engineers and technicians to develop, test, and deliver uncrewed underwater vehicles (UUVs) based on system requirements. Specific development includes software related to operations of UUVs as well as sensor integration.

Required Experience / Skills:

• Develop and refine user interface and control of various sensors integrated onboard UUVs.
• Develop and optimize UUV behaviors to accomplish assigned tasks while maximizing opportunities for sensor data collection.
• Self-motivated engineer with demonstrated hands-on hardware/software bring-up and benchtop troubleshooting experience.
• Strong systems programming capabilities in Linux, Python, and C or C++.
• Practical understanding of TCP networking and socket-level data transport.
• Develop platform-independent data processing tools.
• Produce SW performance reports based on test & evaluation requirements.
• Create engineering & training documentation for technological deliveries.

Testing involves working onboard small boats and ships on the ocean, launching and recovering systems at sea, and post-test analysis of data. Reporting includes providing results from post-test data analysis into official reports or briefing material. Most development and testing will be conducted in San Diego; however, engineers may occasionally travel in support of testing, training and/or operations in other locations both in the U.S. and abroad and may spend multiple days at-sea onboard ships.

• Ability to climb ladders up to 20 feet.
• Able and willing to work aboard marine vessels of various sizes, sometimes overnight.
• Requires work in various temperatures and inclement weather.
• Familiarity with ROS2 package development and DDS middleware.
• Experience interfacing with CAN bus, UDP, and alternate comms (serial, RF datalinks).
• Demonstrated ability to run statistical analyses and generate visualizations on large-scale datasets (telemetry, bench logs).
• Experience working independently or in teams to develop solutions, deliver products, and test and evaluate performance.
• Experience and skill analyzing experiment data to determine results as feedback into the development cycle.
