Job Summary

We are seeking a detail-oriented highly analytical Junior Systems Software Engineer to join our core engineering 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.
