## About the Role

* At least Eight (8) years of experience and strong proficiency with any programming language
 * Strong knowledge of systems programming fundamentals: concurrency, networking, performance profiling, reliability, and distributed systems patterns
 * Experience designing and operating production APIs/services with strong observability, correctness guarantees, and security considerations
 * Ability to work with stakeholders to define platform requirements, design the architecture, and deliver it end-to-end
 * High degree of self-motivation and willingness to jump into unfamiliar areas to solve problems

Bonus:

 * 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

## Description

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