Senior Software Engineer

We’re seeking a Senior Software Engineer to collaborate with a team of software engineers, algorithm engineers, and FPGA/Firmware engineers in addressing emerging challenges in space sensor capabilities. The candidate will primarily work to develop sensor-based products, develop space-based sensor applications to control the sensor’s unique capabilities, and develop capabilities relevant to sensors in an embedded environment using Agile software development methodologies. As a senior software engineer, you will play a pivotal role in ensuring the capability, quality, and reliability of our embedded software and hardware products. This role offers a fantastic opportunity to contribute to Leidos’ mission of delivering cutting-edge solutions for next-generation space capabilities.

Primary Responsibilities

As a senior software engineer, you will have a role consisting of:

• Lead the development of embedded software and firmware for sensor applications and programs.
• Participate in development phases from detailed requirements flow down, trade studies, processing architecture design, hardware selection, firmware and software development, sensor and payload integration and test, spacecraft integration and test, and on-orbit support.
• Actively working with multi-domain team of engineers including software, firmware, electrical, optical, and test engineers to coordinate software efforts across multiple programs, including embedded software, ground support software, test equipment software, and software-in-the-loop (SWIL) and hardware-in-the-loop (HWIL) simulators.
• Analyze user requirements to derive software design and performance requirements.
• Assist with developing and executing test procedures for software components.
• Interface with system engineers and hardware engineers to derive software requirements and to obtain information on project limitations and capabilities, performance requirements and interfaces.
• Integrate existing sensor-based software into new or modified sensors or operating environments.
• Experience with Continuous Integration and Continuous Delivery (CI/CD) tools.
• Conduct design trades of complexity and performance between the payload’s optical front end, algorithm implementation, firmware architecture, and software architecture.
• Investigate potential processing architectures that may incorporate GPUs, CPUs, FPGAs, SoC, and other cutting-edge technologies.
• Mentor Junior software engineers in good engineering practices.

Basic Qualifications:

We’re looking for Software Engineers possessing the basic software foundational skills such as:

• Degree in Electrical, Computer, or Software Engineering, Mathematics, or Physics with 8+ years of relevant experience.
• Experience leading a team of 3+ software engineers.
• Experience working with a multi-domain team of engineers including software, firmware, electrical, optical, and test engineers.
• Understand and experience with Agile Principles and the Scrum framework.
• Understand and perform software code development using C, C++, Java, and Python with the ability to write, maintain, and troubleshoot code.
• Understand and experience with MatLab or Simulink.
• Understand real-time architectures, interrupts, ISRs, and tasks, as well as how to apply object-oriented concepts to embedded systems.
• Understand Memory architecture - static vs dynamic memory and their relationship to stack, heap, and cache memory
• Experience with UART, SPI, I2C and PCIe busses.
• Strong debugging skills to analyze, identify, and isolate software defects and issues in a systematic methodology.
• Experience with Integration & Test, including test automation.
• Familiarity with and understanding of security test tools and practices to identify vulnerabilities in software and static code analysis.
• Proficient in using version control systems (e.g., GitLab, SVN) to manage source code in a defined branching structure.
• U.S. citizen and must be able to obtain and maintain a DoD SECRET clearance.

Preferred Qualifications

• Experience working SDA, MDA, AFRL, and Air Force space programs.
• Understanding of software programming at the OSI Layer 1 – Physical layer.
• Understanding of FPGA, General Purpose Processors (GPP), and Graphical Processor Units (GPU).
• Understanding of containerization such as PodMan or Docker.
• Knowledge of performance testing tools and methodologies to assess the performance and scalability of software applications.
• Experience with image processing algorithms, Kalman filtering, and closed-loop control systems.
• Proficiency in lab tools such as scopes and logic analyzers.
• Experience implementing interfaces such as 1GE Ethernet, 40G QSFP+, LVDS, and serial busses.
• Experience with adaptive signal processing.
• Experience with embedded C and RTOS. Green Hills, specifically, is a bonus.
• Able to obtain a top-secret clearance.
