Full time

Phoenix, United States | Posted on 10/21/2026 Weare seeking a detail-oriented, highly analytical Junior Systems SoftwareEngineer to join our core engineering team. Inthis role, you will design, implement, and optimize low-level applicationarchitecture, networking protocols, and performance-critical systems. The idealcandidate brings a strong foundation in computer science fundamentals, hands‑onexperience with C++ and Python, and a passion for building responsive, scalablesoftware.

Key Responsibilities
Systems & Network Architecture: Design,implement, and maintain custom networking components, client-server models, andprotocol resolvers (UDP/TCP, DNS, socket communications). Algorithm & Performance Optimization: Apply datastructures, memory management, and graph search heuristics (e.g., A*, customhashing, priority queues) to solve complex performance and indexing challenges. Testing & Quality Assurance: Develop andexecute comprehensive unit, integration, and stress tests to validate networkstate synchronization, catch edge cases, and eliminate execution bottlenecks. Debugging & Problem Solving: Utilizelow-level debugging tools (GDB, Wireshark) to trace memory leaks, analyzepacket flow, and debug asynchronous multi-threaded or multi-client executionpaths. Cross-Functional Collaboration: Partner withcross-functional teams to design clean, modular codebases and maintain versioncontrol integrity across all release cycles. Key

Requirements:


Education:
Bachelor of Science in ComputerScience, Computer Engineering, or a related technical discipline (GPA 3.5+preferred). Core Languages: Strong proficiency in C++ and Python .
Familiarity with C, C#, Java, SQL, or x86 Assembly is a plus. Systems & Networking: Solidunderstanding of TCP/UDP networking principles, socket programming, cachingmechanisms, operating systems, and computer architecture. Tools & Environment: Hands-onexperience with Linux/Bash , Git/GitHub , GDB ,and Wireshark . Experience with SFML, Unity, or VR/AR engines isdesirable. CS Fundamentals: Proven command of object-orienteddesign, algorithmic complexity, recursive problem-solving, and concurrent statemanagement. Desired Competencies: Self-startercapable of managing end-to-end projects—from requirement mapping tocomprehensive testing. Passionfor interactive media, high-performance computing, or game engine mechanics. Strongwritten and verbal communication skills for technical documentation and codereviews.
