• Follow coding standards, code review feedback, and team processes

Technical Skills

• Basic understanding of C++ OOP (classes, inheritance, polymorphism)
• Familiarity with STL containers and algorithms (e.g. vector, map)
• Able to write clean, modular C++ code following fundamental principles
• Basic exposure to CMake (targets, linking, include paths)
• Able to debug build failures and dependency issues
• Basic experience using gdb (or willingness to learn quickly)
• Comfortable using the Linux terminal daily
• Understanding of the Linux file system, directory structure, and permissions
• Ability to inspect and manage processes (ps, top, basic systemctl)
• Basic knowledge of package managers (e.g. apt)
• Able to write small bash/sh scripts for automation

Version Control

• Basic Git operations: clone, pull, push, branch, merge
• Able to resolve simple merge conflicts
• Able to follow a branching strategy and participate in code reviews

Soft Skills

• Strong willingness to learn from a senior/tech lead
• Good communication skills and ability to ask for help when stuck
• Attention to detail and a sense of ownership over your work

Nice-to-Have (Good bonuses, not mandatory)

• Interest in financial markets, trading, or quantitative systems
• Experience with multithreading or networking in C++
• Familiarity with CI/CD tools (GitHub Actions, GitLab CI, etc.)
• Exposure to Python for scripting or tooling

What We Offer

• Direct mentorship from an experienced C++ tech lead
• Exposure to real trading systems and infrastructure
• Opportunity to grow into a mid-level role as you take on more responsibility
• Small, fast-moving team where your work has visible impact
