NinjaTrader Arena is our simulated futures trading competition platform and a core growth engine for the company. Arena introduces new traders to futures markets through structured, time-boxed competitions powered by live market data and simulated accounts. It is designed to attract and engage a new generation of retail traders and expand NinjaTrader’s reach beyond our traditional customer base.

The Arena team is iterating rapidly on competition formats, engagement mechanics, real-time leaderboards, and growth loops. The platform must support bursty, marketing-driven traffic patterns and real-time competition dynamics while maintaining clear architectural separation from NinjaTrader’s core trading systems. Arena is a dedicated vertical with its own product and engineering leadership, focused explicitly on user acquisition and growth.

We are hiring a Sr. Engineering Manager to lead Arena engineering. You will build and scale the Arena engineering team, define its technical strategy, and partner closely with Product and Design to shape the future of the platform. In the near term, this means leading a high-velocity squad focused on rapid experimentation and architectural flexibility. Longer term, as Arena achieves product-market fit and scales, this role is expected to evolve into multi-team leadership, shaping the organization, architecture, and operating model of a standalone growth business within NinjaTrader.

In this role you will:

Build and lead the founding Arena engineering team, hiring high-caliber full-stack engineers and establishing a culture optimized for ownership, speed, and technical rigor

Partner deeply with Product and Design as the engineering co-owner of the Arena growth strategy, shaping experimentation velocity, competition mechanics, and platform evolution during product-market fit discovery
