About the Role

We are looking for a Senior C++ Developer to join our team on a contractor basis, focused on building and maintaining low-latency, highly reliable systems that process financial data and transactions under strict correctness, availability, and compliance requirements.

This role requires a hands-on engineer who works close to the core of the system, where performance, determinism, and data integrity are critical. The ideal candidate is passionate about high-performance software, enjoys solving complex technical challenges, and takes full ownership of systems from design to production.

You will collaborate closely with engineering and product stakeholders to evolve existing systems and build new components that operate in demanding, real-time environments.

Responsibilities

• Design, implement, and maintain high-performance C++ applications for financial data processing systems.

• Develop low-latency and performance-critical components, ensuring correctness and reliability.

• Work extensively with multithreading and concurrent programming models.

• Build and maintain networked systems using TCP/UDP, multicast, and socket programming.

• Optimize memory usage and performance through a deep understanding of RAII, object lifetimes, move semantics, and memory management.

• Develop and debug software on Linux environments using tools such as GCC and GDB.

• Take end-to-end ownership of features, from architecture and implementation to deployment and maintenance.

• Collaborate with cross-functional teams to define technical solutions and system behavior.

• Participate in code reviews, architectural discussions, and continuous improvement initiatives.

• Contribute to system architecture, internal tooling, and technical direction.

• Balance speed of delivery with engineering rigor, ensuring scalable and maintainable solutions.

• Document system behavior, architecture decisions, and technical workflows as needed.

Must-Have Requirements

• Strong proficiency in C++ with hands-on experience in production systems.

• Deep understanding of:

  • Memory management

  • Object lifetimes

  • RAII

  • Move semantics

• Proven experience in performance-oriented and low-latency programming.

• Strong knowledge of multithreading and concurrency.

• Experience with network programming (TCP/UDP, multicast, sockets).

• Solid experience developing on Linux, including use of GCC and GDB.

• Ability to work in fast-paced startup environments with evolving requirements.

• High ownership mindset and strong problem-solving skills.

• Openness to feedback, code reviews, and continuous learning.

• Good communication skills in English (written and verbal).

Nice-to-Have / Plus Skills

• Experience using CMake for build configuration.

• Familiarity with vcpkg for dependency management.

• Experience building systems from scratch or significantly evolving existing platforms.

• Interest in contributing to architecture and long-term technical strategy.
