Senior Engineering Manager, Full Stack

Role Overview

• 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
• Define and evolve Arena’s technical architecture, ensuring rapid iteration today while preserving clean boundaries and extensibility for future scale
• Design systems that handle bursty, marketing-driven traffic patterns, real-time competition state, and leaderboard updates without compromising reliability or coupling risk to NinjaTrader’s core trading infrastructure
• Enforce engineering standards for reliability, observability, deployment automation, and operational readiness on Google Cloud Platform, including defining service-level expectations for Arena as an independent vertical
• Own Arena’s engineering execution end-to-end, balancing experimentation speed with long-term system health and technical leverage
• Design the team’s future organizational shape, identifying when to introduce additional squads and technical leadership as Arena scales post product-market fit
• Hire and develop future technical leaders within Arena, building the senior density required to support multi-team growth
• Participate in on-call and incident response as an engineering leader, modeling operational accountability and ensuring systems are built for operators as well as developers
• Represent Arena engineering strategy in cross-functional and executive discussions, clearly articulating trade-offs between growth velocity, system resilience, and architectural investment.
