Software Engineer I

Join Leidos’ Undersea Systems Division in San Diego, CA (onsite) to help rapidly prototype ocean systems. You’ll work alongside a small engineering team and customers to design, build, test, and demonstrate software capabilities that support mission objectives. The role operates on a 9/80B onsite schedule and requires an active Secret Clearance (or the ability to obtain one).

Compensation: USD 69,550 - 125,725 per year.

Responsibilities

• Collaborate with a small engineering team and customers to identify software requirements and evaluate design approaches for solving wide-ranging technical problems.
• Work directly with customers to understand mission needs, translate operational objectives into technical requirements, demonstrate capabilities, and incorporate feedback during development.
• Design and develop maintainable, robust, high-performance software applications, services, data pipelines, and user interfaces.
• Develop Python-based software for data processing, analytics, hardware integration, automation, and test applications.
• Build and integrate web-based and desktop user interfaces for system configuration, data visualization, and operational performance monitoring.
• Implement, test, integrate, and verify software solutions to meet project and customer requirements for functionality, reliability, performance, and usability.
• Create and maintain engineering documentation, including interface control documents, software requirements specifications, test procedures, and user documentation.
• Coordinate development efforts through regular communication with engineers and customers, including prioritizing features and bug fixes and soliciting feedback.
• Support laboratory, field, and at-sea testing of prototype systems by troubleshooting software, hardware interfaces, and operational data flows.
• Present technical concepts, development progress, test results, and product demonstrations to customers and other stakeholders.

Requirements

• U.S. Citizen with an active SECRET security clearance or the ability to obtain one.
• Bachelor’s degree from an accredited institution in Computer Science, Software Engineering, Computer Engineering, or related STEM field.
• Relevant professional, internship, academic, or project experience developing and integrating software applications.
• Proficiency in Python, including using it for applications, automation tools, data-processing solutions, or hardware-control software.
• Experience designing, developing, and integrating REST APIs.
• Working knowledge of software version-control processes and tools such as Git and GitHub.
• Working knowledge of Linux command-line tools and shell scripting.
• Experience testing software and debugging applications that integrate multiple data sources, services, or hardware components.
• Ability to work effectively in a small, multidisciplinary team across multiple phases of the software-development lifecycle.
• Ability to interact directly and professionally with customers, including gathering requirements, communicating tradeoffs, presenting demonstrations, and responding to feedback.
• Ability to understand complex technical documents and communicate technical ideas effectively in writing, orally, and visually.
