Software Engineer, Level 3

What You Will Do

As a Software Engineer, Level 3 at Independent Software, you will serve in a highly customer-facing role leading the development, deployment, and evolution of mission-critical systems supporting modern satellite communication technologies. You will work directly with users and stakeholders to analyze operational needs and translate them into robust, high-performance software solutions.

In this role, you will design, develop, and enhance C++ applications, implement complex algorithms, and ensure software reliability through automated testing and rigorous debugging. You will collaborate closely with cross-functional teams to deliver scalable, secure, and performance-optimized systems that operate in timing- and resource-constrained environments.

• Analyze user requirements to derive software designs for new applications or enhancements to existing systems.
• Ensure new features and capabilities align with mission objectives and project goals.
• Develop high-quality, maintainable C++ code for satellite communication and mission-critical applications.
• Apply best practices, coding standards, and performance optimization techniques.
• Identify, debug, and resolve software defects using systematic troubleshooting and root‑cause analysis.
• Support sustainment and continuous improvement of existing software baselines.
• Design and implement database or data repository interfaces and queries to support application data management.
• Design and implement complex algorithms that meet strict timing, system resource, and interface constraints.
• Optimize software for high performance, reliability, and real-time operation.
• Integrate automated testing into the development lifecycle, including unit testing and regression testing.
• Review and validate software components to ensure adherence to design requirements.
• Work closely with system architects, QA engineers, and project managers to ensure solutions meet user requirements.
• Participate in technical reviews and support on‑time delivery of high‑quality software.
• Maintain comprehensive technical documentation for software designs, algorithms, processes, and interfaces.
• Support knowledge sharing and long‑term project continuity.

• Proficiency in C++ software development for complex, mission-critical systems.
• Experience designing and implementing algorithms for real‑time or performance-constrained environments.
• Knowledge of RF signal analysis or satellite communications system design and theory.
• Familiarity with Dev Ops processes and tools in virtualized and containerized environments, including VMware, Docker, and Kubernetes.
• Experience with message queue technologies and communication protocols.
• Strong analytical and problem-solving skills with the ability to debug complex issues.
• Excellent communication and collaboration skills in customer-facing environments.
• Adaptability and a commitment to continuous learning.

• Doctoral Degree plus 4 years of relevant experience.
• Bachelor’s Degree plus 5 years of relevant experience.
• Associate Degree plus 7 years of relevant experience.
• High School Diploma or GED plus 9 years of relevant experience.

• Must possess an active TS SCI with appropriate polygraph to be considered for this role.
