Familiarity with version control systems like Git, build tools such as Maven or Gradle, and experience with IDEs like IntelliJ IDEA or Eclipse are common technical requirements. Strong problem-solving, eagerness to learn, and effective teamwork are standout soft skills in this role. These skills ensure you can write reliable code, collaborate efficiently, and adapt to evolving technical challenges in software development projects.

  • Optimize algorithms, memory utilization, JVM tuning, and threading models
  • Work closely with senior engineers on architecture, code reviews, and system optimization
  • Support production releases, security updates, and platform enhancements
  • Utilize low-level diagnostic tools to analyze system behavior and optimize performance
  • Develop clean, scalable, maintainable Java applications supporting mission-critical trading systems


Required Experience

  • 8+ years of Core Java software engineering
  • Recent experience developing low latency trading platforms
  • Experience supporting electronic trading or capital markets systems
  • Strong understanding of trading workflows and market data processing
  • Experience building backend trading applications—not database-centric applications

  • Advanced knowledge of multithreading, concurrency, synchronization, shared memory, and asynchronous programming
  • Strong understanding of algorithms and data structures
  • Experience optimizing high-performance Java applications
  • Experience working with TCP/IP and UDP networking
  • Strong Linux experience
  • Self-starter capable of contributing immediately with minimal supervision

  • Production Support

Preferred experience with:

  • Solarflare Networking
  • EF_VI
  • Onload APIs
  • Thread Pinning
  • NUMA Architecture
  • CPU Cache Optimization
  • Interrupt Handling
  • Packet Capture
  • Hardware Performance Counters


Trading Domain Experience Required

Candidates should have experience working with one or more of the following:

  • Electronic Trading Platforms
  • Matching Engines
  • Order Book Management
  • Market Data Processing
  • Trading Logic
  • Credit Checks
  • Order Routing
  • Market Connectivity
  • Exchange Connectivity
  • Capital Markets Technology


What We're Looking For

We're looking for an engineer who understands the unique challenges of building software where performance, determinism, and reliability are critical.

This is an opportunity to work on highly sophisticated trading technology alongside experienced engineers solving complex performance and scalability challenges.


Important Requirements

  • Hybrid schedule (2 days per week in the office)
  • Chicago or New York
  • Long-term consulting opportunity
  • Must have recent low latency trading platform experience
  • Must have financial services or capital markets experience
  • No Third Parties
