Exchange Software Engineer

About this role

Bitnomial seeks an Exchange Software Engineer to design and maintain critical infrastructure for a CFTC-regulated digital assets derivatives exchange, including matching engines, clearing systems, and risk management. The role combines high-performance, low-latency systems development with the strictness required for regulated capital markets, primarily using Haskell.

What you'll do

• Design and own core exchange and clearing services: matching engines, order lifecycle, margin, risk, settlement, and market data systems
• Build and maintain low-latency, high-correctness systems that handle real capital in regulated environments
• Debug and optimize across application, network, and system layers in production
• Create system architecture documentation and technical design decisions for complex, constrained problems
• Operate services end-to-end including observability, monitoring, and operational runbooks
• Ensure correctness and failure mode handling in systems directly connected to capital markets

What they're looking for

• Strong expertise in compiled, statically typed languages (Haskell, Java, C++, Scala, OCaml, or Rust)
• Concurrent and multithreaded systems design
• Linux systems administration, debugging, and profiling
• Networked systems and binary protocols (TCP, serialization, FIX preferred)
• Relational databases, especially PostgreSQL
• Trading systems experience (order execution, risk, margin, settlement, or market data)
• Functional programming and type system design
• Technical documentation and clear architectural communication
