Clear Street is modernizing the brokerage ecosystem. Founded in 2018, Clear Street is a diversified financial services firm replacing the legacy infrastructure used across capital markets.

We started from scratch by building a completely cloud-native clearing and custody system designed for today's complex, global market. Our platform is fully integrated with central clearing houses and exchanges to support billions in trading volume per day. We've agonized about our data model abstractions, created horizontal scalability, and crafted thoughtful APIs. All so we can provide a best-in-class experience for our clients.

By combining highly-skilled product and engineering talent with seasoned finance professionals, we're building the essentials to compete in today's fast-paced markets.

 

The Team:
The mission of the Clear Street Active team is to provide best execution for every asset class in every market. Active is currently building a new, state-of-the-art, cloud-based trading platform providing high-performance traders access to liquidity venues across multiple asset classes, cutting-edge charting capabilities, and sophisticated order handling with the flexibility to service both the active trader and institutional workflows.

The Role:

• 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

Requirements:

• 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
