Careers

Senior C++ Developer

Mathisys Technologies Hellas, a quantitative and algorithmic trading research center, is seeking a Senior C++ Developer to join our engineering team. This is a full-time, on-site position in Athens.

Role Description

At Mathisys, C++ Developers are the architects of speed, logic, and precision. You will be part of a small, focused team building the software that powers our quantitative and algorithmic trading systems, systems engineered to operate where performance, reliability, and clarity converge.

Your day will blend high-level architecture with low-level optimization. One moment you’ll be designing frameworks for real-time data processing, and the next you’ll be profiling critical paths to eliminate microseconds. You’ll collaborate with quantitative researchers, integrating complex models into production environments that demand flawless execution.

This role is suited for engineers who thrive in technically demanding environments, where clean design, mathematical thinking, and disciplined execution are valued as much as creativity. At Mathisys, code is not just written, it’s engineered, modeled, and refined to perform at scale.

About the team

The Research & Alpha team brings quantitative researchers, software engineers and infrastructure specialists together around one goal: turning rigorous ideas into reliable systems. Small, multidisciplinary groups work closely from hypothesis through production, sharing ownership of performance, resilience and continuous improvement.

What You'll Do

  • The firm designs advanced trading models and implements sophisticated strategies for global financial markets.
  • The successful candidate will be responsible for software design and development in a fast-paced, adaptive environment.

Must-Have Qualifications

  • Bachelor’s or Master’s degree in Computer Science or a related field.
  • Strong C++ programming and software development skills.
  • Experience in algorithmic trading or quantitative finance is a plus.
  • Excellent problem-solving and analytical abilities.
  • Knowledge of UNIX/Linux operating systems and scripting.
  • Strong written and verbal communication skills in both Greek and English.
  • Ability to work effectively in a fast-paced, dynamic, and collaborative multicultural environment.

What we offer

  • Competitive salary with high-performance bonuses.
  • Private health insurance.
  • Collaboration with an international team of analysts.
  • Work with cutting-edge technologies, including low-latency systems, machine learning, and state-of-the-art trading systems.
  • Friendly, efficient, and motivating work environment.
