We are seeking a
detail-oriented, highly analytical Junior Systems Software Engineer to join our
core engineering team. In this role, you will design, implement, and optimize
low-level application architecture, networking protocols, and performance-critical
systems. The ideal candidate brings a strong foundation in computer science
fundamentals, hands-on experience with C++ and Python, and a passion for
building responsive, scalable software.
Key Responsibilities:
· Systems & Network Architecture: Design,
implement, and maintain custom networking components, client-server models, and
protocol resolvers (UDP/TCP, DNS, socket communications).
· Algorithm & Performance Optimization: Apply data
structures, memory management, and graph search heuristics (e.g., A*, custom
hashing, priority queues) to solve complex performance and indexing challenges.
· Testing & Quality Assurance: Develop and
execute comprehensive unit, integration, and stress tests to validate network
state synchronization, catch edge cases, and eliminate execution bottlenecks.
· Debugging & Problem Solving: Utilize
low-level debugging tools (GDB, Wireshark) to trace memory leaks, analyze
packet flow, and debug asynchronous multi-threaded or multi-client execution
paths.
· Cross-Functional Collaboration: Partner with
cross-functional teams to design clean, modular codebases and maintain version
control integrity across all release cycles.
Key Requirements:
· Education: Bachelor of Science in Computer
Science, 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: Solid
understanding of TCP/UDP networking principles, socket programming, caching
mechanisms, operating systems, and computer architecture.
· Tools & Environment: Hands-on
experience with Linux/Bash, Git/GitHub, GDB,
and Wireshark. Experience with SFML, Unity, or VR/AR engines is
desirable.
· CS Fundamentals: Proven command of object-oriented
design, algorithmic complexity, recursive problem-solving, and concurrent state
management.
Desired Competencies:
· Self-starter
capable of managing end-to-end projects—from requirement mapping to
comprehensive testing.
· Passion
for interactive media, high-performance computing, or game engine mechanics.
· Strong
written and verbal communication skills for technical documentation and code
reviews.
