Responsibilities

• Develop a high-performance backend in Rust that supports streaming responses, low-latency tool execution, caching, and reliable orchestration of model + tools.
• Build the core AI platform that powers a copilot inside a new, AI-native trading experience.
• Design robust APIs and runtime components for AI capabilities: authentication/authorization, rate limits, auditing, tracing, retries, and fallbacks.
• Build safe action infrastructure for trading workflows: deterministic order previews, confirmation flows, idempotent tool calls, and comprehensive audit logs.
• Partner with product and frontend to enable great AI-native UX patterns (streaming, citations/grounding, "why" explanations, reversible actions).
• Develop a deep understanding of the business domain and help translate it into secure, resilient platform primitives.

• High degree of self-motivation and willingness to jump into unfamiliar areas to solve problems.

Nice-to-Haves

• Strong Rust experience in production (Tokio/async, service design, performance tuning).
• Experience building platforms for AI/ML inference, tool execution, streaming, or retrieval/grounding systems.
• Experience in trading systems (order lifecycle, execution, risk checks, auditability) or other mission-critical financial infrastructure.
• Deep experience with trading across asset classes, margin types, etc.
• Experience with Postgres performance and data modeling in high-throughput systems.
