Clear Street is modernizing the brokerage ecosystem with a cloud-native clearing and custody system supporting billions in daily trading volume. The Active team is building a state-of-the-art, cloud-based trading platform providing high-performance traders access to liquidity venues across multiple asset classes with cutting-edge charting and sophisticated order handling.
You will build the core AI platform powering a copilot inside a new AI-native trading experience. This is a platform engineering role focused on creating the infrastructure that enables AI capabilities in a mission-critical financial system.
Key responsibilities:
- Develop a high-performance backend in Rust supporting streaming responses, low-latency tool execution, caching, and reliable orchestration of models and tools
- 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 teams to enable AI-native UX patterns (streaming, citations/grounding, explanations, reversible actions)
- Develop deep understanding of the business domain and translate it into secure, resilient platform primitives
Tech stack: Rust (backend), Postgres, TypeScript, React / React Native, LLM APIs / model serving.
Requirements:
- At least 8 years of software engineering experience with strong proficiency in 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 architecture, and deliver end-to-end
- High degree of self-motivation and willingness to jump into unfamiliar areas to solve problems
Bonus qualifications:
- Strong production Rust experience (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 mission-critical financial infrastructure
- Deep experience with trading across asset classes and margin types
- Experience with Postgres performance and data modeling in high-throughput systems
