Scored from the posting itself — how clearly the role is described, how much it says about pay and benefits, and how recently it was listed. Not a judgement of NinjaTrader as an employer.

What you need

  • 6+ years of professional software development experience building and operating backend services in production
  • Bachelor's or Master's degree in Computer Science, Software Engineering, or a related field (or equivalent practical experience)
  • Deep Node.js and TypeScript expertise, with strong command of asynchronous patterns, concurrency, and backpressure
  • Proven production experience with event-driven architecture, including delivery guarantees and poison-message handling, on message queues, pub/sub, or streaming platforms such as Kafka or Google Cloud Pub/Sub
  • Demonstrated experience building idempotent, resumable workflows that stay correct under retries, partial failure, and out-of-order delivery
  • Strong SQL and schema design, plus hands-on experience with Docker, Kubernetes, and a major cloud platform

Nice to have

  • Experience with identity verification, KYC/AML, or fraud and risk decisioning systems
  • Experience in fintech, trading, or brokerage, particularly in a regulated financial services environment
  • Experience integrating third-party providers whose contracts and failure modes you do not control
  • Familiarity with workflow or saga orchestration frameworks, and with feature flagging platforms such as Statsig
  • Passion for futures, derivatives, and trading technologies is a strong plus

What you get

  • Salary range of $140,000.00 - $190,000.00 USD
  • Annual target bonus of 12% based on individual and company/team performance
  • 401K plan with company match up to 3.5%
  • Annual paid time off allowance of 18 days plus seven paid holidays
  • Hybrid work schedule for Chicago-based employees
  • 20 additional flex remote days annually

Worth weighing

  • No specific mention of the tech stack beyond Node.js and TypeScript, which may imply a focus on these technologies
  • The role involves significant ownership and responsibility, which may be challenging for some candidates
  • Remote flexibility is limited to certain states and exceptional candidates only
  • The position is part of a hybrid work model, requiring in-office presence for part of the week
