Job Title: Software Engineer – Algorithms
Location: Plano, TX (On-site)
Clearance Requirement: Active DoD Secret clearance required prior to start; ability to obtain a higher clearance after hire Role Overview
We are seeking a Software Engineer with experience developing and optimizing algorithm-driven software for both high-performance computing environments and real-time operational systems. This role focuses on translating advanced algorithm concepts into efficient, production-ready implementations that meet strict performance and reliability requirements.
You will work in a collaborative, cross-functional environment alongside technical experts to support the development of complex systems that require scalable computation, precise execution, and continuous improvement through testing and validation. Key Responsibilities Collaborate with domain experts to understand algorithm objectives, constraints, and performance expectations
Optimize software for performance using parallel processing techniques and hardware acceleration such as GPUs
Convert algorithm prototypes developed in high-level environments into optimized implementations using lower-level languages for production use
Design, implement, test, and debug software within real-time and distributed system environments
Develop and execute large-scale simulations and performance testing across multi-core architectures
Enhance system performance through profiling, tuning, and iterative optimization efforts
Contribute to system architecture decisions and ensure alignment with overall program objectives
Participate in design reviews and technical discussions to improve system quality, reliability, and maintainability
Support integration and testing activities across complex, multi-component systems
Collaborate with engineering teams to ensure seamless system integration and improved product outcomes Required Qualifications Bachelor’s degree in Computer Science, Engineering, or a related STEM field
At least 2 years of professional experience developing software solutions
Experience with real-time or performance-critical software implemented in C, C++, or similar languages
Experience working within Linux-based development environments
Ability to relocate to Plano, TX or currently located in the area
Active DoD Secret clearance required prior to start
Ability to obtain a higher clearance level after hire Preferred Qualifications Background in mathematics, signal processing, or computational modeling
Experience working with large, complex codebases and distributed systems
Familiarity with Agile development practices such as Scrum
Experience using version control tools such as Git and issue tracking tools like Jira
Experience working with parallelized or high-throughput processing systems
Experience with GPU programming and acceleration techniques
Familiarity with high-performance computing environments and large-scale simulation frameworks
Experience using tools such as Python or MATLAB for analysis, modeling, or algorithm prototyping
Active higher-level clearance is a plus Work Environment On-site role supporting a secure, mission-driven program
High-collaboration engineering environment with strong focus on innovation and technical excellence
Opportunity to work on advanced systems that require precision, performance, and scalability
