Senior C++ developer
We are looking for a talented Senior C++ Developer with 5+ years of programming background to make consistent, high-quality code contributions to a mature, high-performance C++ product in the energy commodities trading domain.
This is not a from-scratch build — you'll be joining a live, production trading system where every millisecond counts, with real opportunity to influence the technical direction of a core part of the platform.
JOB REQUIREMENTS:
Must have:
- 5+ years of professional experience in software development
- Deep expertise in Modern C++ (17/20/23): move semantics, constexpr, templates, etc.
- Strong experience with Linux / POSIX environments
- Proficiency with build systems and tools: CMake / vcpkg, Git
- Hands-on experience with concurrency and shared memory tools
- Networking skills: ZeroMQ (or similar), low-level socket programming (TCP/UDP)
- Proficiency in using AI coding tools (Cursor, Claude, Codex, etc.) to enhance the development workflow
- English: Upper-Intermediate or Advanced
Nice to have:
- Experience with Svelte
- Familiarity with kdb+, TypeScript, and code generation tools
- Experience in Financial or Trading domains (FIX Protocol, OMS, market data feeds like ITCH/OUCH)
- Knowledge of Redis or other in-memory data stores
- Familiarity with the Qt framework
- Team lead experience (optional, not required)
WHAT WE ARE LOOKING FOR:
- Autonomy: You excel at working independently, learning on your own, and figuring out large, unfamiliar codebases without external support.
- Ownership: You are ready to take full responsibility for the core part of the system.
- Assertiveness: You can clearly communicate your technical vision and demonstrate your project understanding effectively.
