Careers

Who We Are

We are a small, focused, and exceptionally competitive proprietary trading firm specializing in high-performance on-chain trading. Unlike larger institutions with multiple layers of hierarchy, we operate as a tight-knit group of engineers and quants who work collaboratively to push the boundaries of speed and efficiency. Our edge lies in deep, hands-on engineering—ranging from networking optimizations to advanced data pipelines—where performance truly matters.

Our Mission

To dominate on-chain markets through superior technology, aggressive innovation, and a relentless drive for efficiency. We believe in leveraging every competitive advantage possible, from complex HPC solutions to optimizing lower-level code in C, Rust, and Python.

Why Join Us

  • High Impact & Ownership: In a small team, every line of code and every idea can translate directly into tangible market performance.
  • Cutting-Edge Technology: We explore advanced concepts in systems programming, data processing, HPC, and decentralized technologies.
  • Competitive Rewards: We operate on a profit-sharing model where impactful contributions translate into substantial upside.
  • Remote-First Culture: Our team is global, with members across Europe, Australia, North America, and Asia. We embrace remote collaboration.
  • Financial Security: We maintain a strong runway (targeting at least two years) to ensure a stable environment while exploring new strategies and maintaining existing ones.

Our Culture

  • Self-Starter Mindset: We thrive on autonomy. You'll take end-to-end ownership of your projects, from design to deployment.
  • Results-Oriented: Speed matters—both in the markets and in our development cycles. We constantly iterate, optimize, and refine.
  • Collaborative & Transparent: Despite being remote, we communicate daily, share code freely, and help each other troubleshoot.
  • Lean & Agile: There is minimal bureaucracy. We move fast, adapt quickly, and are not afraid to pivot when market conditions change.

Technical Landscape

  • Languages & Tools: Primarily C, Rust, Python, with some C extensions to support performance-critical components in Python.
  • High-Performance Trading Stack:
    • Optimized Node Integrations (C-based or Rust-based)
    • Large-Scale Data Pipeline with tools like ClickHouse (~50TB+) and Dask
    • IPC and Cross-Region Messaging solutions for real-time event handling
  • Infrastructure: Fully remote with globally distributed servers; HPC focus to achieve top-tier latency in trading.

What We Look For in All Candidates

  1. Autonomy & Drive: You enjoy figuring out complex problems without heavy oversight.
  2. Passion for Performance: Every millisecond (or microsecond) counts. You're excited by optimizing code and workflows, whether it's a network protocol or a graphical dashboard.
  3. Team Player: Small team means high collaboration. Be ready to switch contexts, review code, and offer constructive feedback.
  4. Curiosity & Continuous Learning: We move at market speed. Staying current on new tools and technologies is essential.

Practical Details

  • Location: Fully remote. Current team members span Europe, Australia, North America, and Asia.
  • Compensation: Competitive base with significant performance-based upside (profit-sharing).
  • Runway & Stability: We maintain a target of two years' operating runway to ensure a stable work environment and the freedom to pursue new opportunities.

If you’re passionate about pushing boundaries in on-chain trading and have the skills to thrive in a high-autonomy, high-impact environment, we want to hear from you. Join us to help shape the future of decentralized markets—and get rewarded for building the fastest systems (and the most efficient dashboards) in the space.
