The position is fully on-site in Richardson, Texas, within a small, highly technical engineering team, and offers a flexible work environment and strong benefits when converted to full time.

• Design, develop, and maintain application-level software for secure and non-secure telephone applications and related telecommunication equipment.
• Derive, analyze, and document clear and complete software requirements.
• Perform both preliminary and detailed software design, including high-level architecture and object-oriented design.
• Implement software using C++ (and other C-based languages as appropriate) in a Linux/Unix environment, starting projects from scratch rather than only sustaining existing code.
• Write, maintain, and execute unit, integration, and system-level software tests to ensure quality and reliability.
• Apply established software engineering practices throughout the development life cycle, including design, implementation, testing, and maintenance.
• Collaborate with other engineers on complex systems, contributing to design discussions and technical decision-making.
• Work with software-hardware interfaces as needed to ensure proper integration with telecommunication equipment.
• Estimate, plan, and manage personal work to meet deliverables and project deadlines with limited supervision.
• Communicate effectively in written and verbal form with team members, documenting designs, requirements, and test results.
• Demonstrate leadership potential by taking initiative, driving tasks to completion, and supporting team goals.
• Continuously improve code quality, design approaches, and development processes in line with best practices for object-oriented programming.

• Bachelor’s or Master’s degree in Computer Science or an engineering-related field.
• Approximately 5–8+ years of experience in software engineering, with at least 2–7 years of hands-on software engineering experience emphasized and a preference for mid-level candidates.
• 8+ years of experience using C++ application programming, which may include educational experience, with strong coding and design skills.
• Proficiency in C++ in a Linux/Unix or similar operating system environment.
• Strong object-oriented programming skills and experience with object-oriented software development methodologies.
• Solid understanding of software engineering practices, including the full development life cycle.
• Experience designing high-level software architecture and starting new codebases from scratch.
• Demonstrated ability to work on complex systems and meet deliverables with limited supervision.
• Strong problem-solving skills and the ability to analyze and resolve technical issues effectively.
• Organizational and planning skills to manage tasks and deadlines in a dynamic environment.
• Effective written and verbal communication skills.
• Strong interpersonal skills and the ability to work collaboratively within an engineering team.
• Self-driven, motivated, and able to take initiative in technical and project-related tasks.
• Familiarity with Linux or other Unix-like operating systems as a core development environment.

• Experience with Qt, Google Protocol Buffers, C++11, Boost, and software-hardware interfaces is a plus.
• Experience with any C-based programming languages beyond C++ is welcome, especially with strong object-oriented design skills.
• Leadership experience or demonstrated leadership potential is highly valued, though not strictly required.
• Preference for candidates willing to acquire a DoD security clearance.
• Ability to rate and reflect honestly on proficiency in C++ and other programming languages to support skill assessment.
• Experience working in small, agile engineering teams is beneficial.
• Bachelor of Science in Computer Science is particularly relevant, though related engineering degrees are also suitable.
• Excellent communication skills, including the ability to explain complex technical concepts clearly to peers.
