> Build high-performance Rust backend and core AI platform powering an AI-native trading copilot with streaming, low-latency tools, safe trading actions, and robust APIs. Requires 8+ years experience in systems programming, production services, and architecture.

## Job Description

## 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.

## Requirements
- At least 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.

## 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.

## Compensation
- Base Salary Range: $170,000 - $240,000 (does not include bonuses or equity).
- Competitive compensation packages, company equity, 401k matching, gender neutral parental leave, and full medical, dental and vision insurance.
