We believe that change starts together. It begins with bold ideas, relentless execution and people who want to build what’s next.

If you’re driven by purpose and thrive in environments where your work defines the next chapter of an industry, you’ll feel right at home here.

About the Role

Build a production-grade exchange from scratch within 6 months and lead the migration of anexisting $1B+ daily volume futures business without compromising latency, reliability, or correctness. Take direct ownership of mission-critical systems operating at massive scale, with high autonomy, high impact, and minimal bureaucracy. Drive and define core architectural decisions from day one while shaping the foundation of the platform for long-term scalability and performance.

What You’ll Do:

• End-to-end architecture ownership of core exchange systems
• Design and build matching engine, order lifecycle (pre-trade, trade, post-trade), risk & liquidation, and market data pipelines
• Build for ultra-low latency, high throughput, and deterministic execution at scale
• Lead and mentor a ~25-member engineering team
• Drive architecture reviews, system design decisions, and engineering best practices
• Define latency budgets, throughput benchmarks, and performance SLAs
• Design failure handling, fault tolerance, and recovery strategies
• Build cloud-native, horizontally scalable systems with strict determinism requirements
• Ensure production readiness through observability, rollbacks, and incident prevention mechanisms
• Own reliability, correctness, and performance of mission-critical trading systems

You’ll Excel in This Role If You Have:

• 15+ years of experience in backend engineering or distributed systems
• Direct experience in one or more of the following domains:
• Exchange systems / matching engines
• HFT or ultra-low-latency trading infrastructure

• Deep understanding of multithreading, lock-free data structures, and memory optimization techniques
• Solid grasp of network-level optimization (TCP/UDP, kernel tuning fundamentals)
• Strong domain knowledge of:
• Order matching
• Trade lifecycle (pre-trade, trade, post-trade)
• Clearing and settlement concepts
• Proven experience building systems where latency, correctness, and uptime are equally critical

Strong signals (good to have)

• Experience building or scaling systems using Aeron or similar low-latency messaging frameworks
• Experience with Apache Kafka for asynchronous or non-critical workflows
• Familiarity with Kubernetes-based deployments
• Experience designing or building:
• Risk engines and liquidation systems
• Market data distribution platforms
• Hands-on experience with high-throughput systems (100K+ events/sec or equivalent scale)
• Familiarity with Java-based trading or exchange ecosystems

You’ll Know You’re Winning When

• Core exchange system designed, built, and deployed to production
• Successful migration of existing $1B+ daily volume business with zero major incidents
• Latency and throughput benchmarks are competitive with top-tier global exchanges
• System demonstrates production-grade maturity with:
• Full observability across critical paths
• Strong fault tolerance and graceful degradation under stress
• Stable performance under peak and extreme load conditions
• Engineering organization is aligned on:
• Strong ownership and accountability
• High engineering standards and discipline
• Consistent architecture and design principles across teams

Hiring Process:

Here’s what your journey with us looks like:

• Application Review – We assess for skills, alignment, and intent
• Recruiter Connect – A short conversation to understand you better
• Functional Round(s) – Deep dive into your approach, craft, and problem-solving
• Assignment / Simulation Round – A take-home task or live problem-solving exercise to understand how you think and execute in real scenarios
• Culture & Values Discussion – A conversation to understand our ways of working and how you thrive best
• Founder Conversation (Optional) – For certain roles and senior levels, you may meet our founders to explore strategic alignment and long-term fit
