The Opportunity  

We're looking for an engineer who thinks in systems, leads with vision, and sees AI as a force multiplier for everything we do .  

As a Principal Software Engineer for Data and Billing , you will help lead QA activities for our billing platform, where we shadow and validate over $1B in annual revenue .  You'll work on streaming data testing, agentic coding workflows, and AI-driven tools that turn our billing data into revenue forecasting and strategy insights for the business.  

We cover billing for one of the world's largest exchange operators , and we're scaling fast .  The goal is full coverage across all billing programs, plus support for new business initiatives, monthly strategy shifts, and ongoing consulting with our development teams , Operations , Finance, Accounting, and the broader business teams.  

We also want to put our billing data to work .  With agentic tooling and AI on top of our shadow billing platform, we can model future revenue, forecast demand, and give the business real-time input on pricing and program strategy.  

What You'll Do  

• Build agents and MCPs into our test harness es to automate bug triage and generate agentic tests, so our coverage scales without scaling headcount  

• Take on customer billing program testing, validating C++ logic against massive files output from the trading system
