Cti Staffing

Senior Software Engineer

CTI Staffing is partnering with a leading financial services organization to find a Senior Software Engineer for their electronic trading platforms team, based onsite in Jersey City, NJ. This team builds low-latency, high-throughput trading infrastructure that powers mission-critical capital markets workflows. You'll be a hands-on senior contributor designing and tuning distributed, event-driven systems where microseconds matter — and where the engineering directly impacts trade execution at scale. This is a role for someone who loves the hard performance problems and wants to own them.

What You'll Do

• Architect and develop distributed, event-driven systems optimized for low latency and high throughput
• Build and tune high-performance C++ components on Linux
• Implement asynchronous processing and resilient messaging using UNIX IPC mechanisms
• Diagnose and resolve performance, scalability, and resilience bottlenecks across the platform
• Work with real-time market data feeds and trading workflows end to end
• Mentor engineers and promote performance-engineering best practices
• Support production systems, including participation in a weekly on-call rotation
• Collaborate across teams to deliver seamless, end-to-end trading solutions

Requirements

• Must-Have: 8+ years of hands-on software design and development, with deep production C++ on Linux
• Strong command of UNIX IPC mechanisms (shared memory, sockets, message queues)
• Proficient shell scripting in a Linux/UNIX environment
• Experience working with real-time market data or comparable latency-sensitive data systems
• Proven ability to build scalable, distributed, asynchronous, event-driven applications
• Hands-on performance tuning and low-latency design patterns
• Willingness to work onsite 5 days/week and participate in an on-call rotation
• Nice-to-Have: FIX protocol and FIX engine experience
• Low-latency messaging exposure (e.g., Kafka, 29West)
• Capital markets / trading platform or order management background
• Familiarity with CI/CD tooling (Git, Maven, Jenkins, Artifactory)
• Exposure to AI developer-assist tools (e.g., GitHub Copilot)

Technical Environment: C++, Linux/UNIX, shell scripting Distributed, event-driven, low-latency systems Real-time market data pipelines Messaging frameworks and IPC

What Success Looks Like: Independently owning and optimizing core platform components within the first 3–6 months Measurably improving latency or throughput on a critical workflow Contributing reliably to production stability and on-call rotation
