The role

You will build agents and inference-backed systems into a real-time streaming platform. You will design, prototype, and ship AI-powered capabilities to improve player experience and performance.

What you will do

• Design, prototype, and ship AI-powered capabilities across the streaming platform and player experience.
• Apply inference and agents to real-time performance, player engagement, personalization, and accessibility.
• Use AI to understand, optimize, and evolve large existing codebases, including the streaming stack.
• Build and extend the platform in C++.
• Build production AI needs including evaluation, telemetry, guardrails, fallbacks, and attention to latency and cost.
• Turn ambiguous ideas into demos and experiments, measure what works, and harden it for production.
• Work AI-natively using coding agents, automation, and rapid exploration.
• Work with a small engineering team and partners across streaming, platform, and cloud.

Required qualifications

• BS in Computer Science or a related field, or equivalent practical experience.
• Senior-level software engineering experience with a track record of owning complex systems end to end.
• Strong C++ skills from professional work in production codebases.
• Hands-on experience building and deploying agents or AI-powered features in production.
• Experience with evals, regressions, latency, cost, and system failures.
• Strong grasp of turning models into products including context and prompt design, tool use and orchestration, memory and retrieval, model selection, and inference placement.
• Fluency with AI-native engineering workflows.
• Product judgment.
• Ability to work in ambiguity, move quickly, and keep momentum as priorities change.
• Clear communication, strong ownership, and a habit of making the people around you better.
