We are hiring another great Senior Software Engineer with C++ expertise

Are you a passionate developer who loves building ultra‑low‑latency systems that directly impact live trading environments? We're looking for a Software Engineer (C++) to join a proprietary high‑frequency trading (HFT) firm operating in the crypto markets. You'll enhance and maintain a custom‑built trading platform written primarily in modern C++, while contributing ideas and tech solutions that push the boundaries of digital‑asset trading.

This is not your typical software role; our work lives at the intersection of real‑time systems, financial data, and strategic execution. If you thrive in fast‑paced environments and enjoy taking ownership of your code, this is your chance to work with a tight‑knit team that's shaping the future of crypto trading.

Who We Are

We're a proprietary HFT firm in the crypto industry. Our platform powers a wide range of market‑making strategies across global cryptocurrency exchanges. By providing liquidity and stabilizing bid/ask spreads in spot markets, we play a key role in ensuring fair and efficient pricing for all participants. As part of a broader group of companies in the digital‑asset space, we benefit from shared knowledge and resources while maintaining our own focused identity. With a team of 90+ professionals and a collaborative, tech‑driven culture, we're building tools to lead the next wave of innovation in digital finance.

Responsibilities

  • Develop and maintain the backend of a custom‑built, high‑performance C++ trading platform
  • Build and integrate new trading strategies within the system
  • Connect and manage third‑party APIs for market data and trade execution
  • Provide operational support to ensure smooth performance in live trading environments
  • Propose new features and tools that improve system robustness and performance

What You Bring

  • MSc degree (or equivalent experience) in Mathematics, Physics, Econometrics, Artificial Intelligence, or a related field
  • Minimum of 2 years of experience in a Trading Engineer or low‑latency backend development role
  • Strong experience with modern C++ (17/20), multi‑threading, and network programming on Linux
  • Deep understanding of performance optimization and real‑time, event‑driven architectures
  • Experience with API development and integration (FIX, WebSocket, REST, or exchange‑specific protocols)
  • Working knowledge of MySQL (or similar SQL databases)
  • Familiarity with Redis and Docker
  • Nice to have: Python or for scripting, tooling, or dashboards

What We Offer

  • Competitive salary
  • Innovative Work:
    Be part of a team driving new technology in the crypto trading space
  • Modern Workspace:
    Work in our new office at Schiphol‑Rijk
  • Daily Perks:
    Free lunch, fresh fruit, and weekly Friday drinks at our in‑house bar
  • Team Culture:
    Monthly team events and activities
  • Commuting & Pension:
    Travel allowance and a solid pension plan
  • Benefits & Wellness:
    25 vacation days, monthly chair massages, gym access, and the Alleo benefit platform
  • Home Setup:
    €250 home‑office budget after your probation period

We do not provide visa sponsorship.
