The Role

We’re looking for a Senior Trading Systems Developer with strong experience in Java, Python, and full stack development to architect and build our next-generation trading applications and electronic trading execution platform. This platform will be central to supporting complex electronic trading workflows, such as market making and internalizing flow spanning high- and low-touch desks. You’ll be designing and developing scalable, low-latency components that are resilient under heavy load and tightly integrated with our execution stack and internal trading infrastructure.

  • Drive the development of intuitive front-end UIs for traders and sales desks, collaborating with dedicated frontend engineers
  • Define, build, and enforce data models that power real-time order tracking, workflow queues, and reconciliation
  • Own full SDLC for your domain: design, test, ship, monitor
  • Lead, mentor and collaborate with junior engineers and contractors
  • Operate in a fast-paced Agile environment, contributing to team structure, sprint planning, and execution cadence

What We’re Looking For

  • 5+ years of experience in trading systems, ideally with prior design ownership
  • Strong backend development skills in Java (11+) plus Python or Go
  • Experience with React, TypeScript, or similar modern frontend frameworks
  • Solid full-stack engineering background, able to contribute across backend, frontend, and database layers
  • Deep understanding of order state machines, trader workflows, and institutional trade lifecycle
  • Strong experience designing normalized schemas and working with relational databases (e.g., Postgres, MySQL)
  • Experience with high-touch trading workflows (sales traders, RFQ, block trades)
  • Experience with middle and back office, such as booking, settlement and clearing
  • Experience with message bus frameworks (Aeron, Kafka, etc.)
  • Experience building and consuming REST, WebSocket, and FIX APIs
  • Experience with Agile delivery, sprint planning, and team leadership
  • Passion for clean architecture, maintainability, and performance

Bonus Points

  • Prior experience in crypto markets or electronic trading in traditional finance.
  • Experience integrating execution platform with strategy containers, risk engines, or smart order routers.
  • Knowledge of FIX protocol nuances and connectivity to major exchanges.
  • Exposure to container orchestration, service mesh, or hybrid deployment architectures.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
