Overview

The Financial Risk Management (FRM) team builds real-time monitoring, data visualization, and AI-driven automation systems to ensure platform integrity. We are seeking a Senior Full-Stack Engineer (backend-leaning) to architect scalable data systems, microservices, and AI-powered workflows while also delivering high-quality frontend experiences.

You will design end-to-end systems spanning databases, APIs, AI integrations (LLMs/agents), and React-based dashboards handling real-time risk data with low latency.

Key Responsibilities

• System Design & Backend Architecture: Build scalable, low-latency systems for real-time risk data; design SQL/NoSQL schemas and data pipelines.
• APIs & Microservices: Develop REST, GraphQL, WebSockets, and gRPC services; implement microservices and MCP-based AI integrations.
• AI/LLM Integration: Deploy production LLM systems (OpenAI, Anthropic); build agent workflows using LangGraph, CrewAI, function calling, and tool-use patterns.
• Frontend Delivery: Convert Figma/prototypes into React + TypeScript apps; manage state using Redux/Saga or Zustand; use TanStack Query for server state.
• Performance & Observability: Optimize real-time systems; implement AI observability tools (LangSmith, Opik), retry logic, and hallucination detection.
• AI-Driven Development: Use tools like Cursor, GitHub Copilot, and Codex to accelerate development and refactoring.

Required Qualifications

• 7+ years of software engineering experience in scalable backend and system design, with full-stack exposure.
• Strong expertise in Python (FastAPI/Flask) and Node.js.
• Advanced frontend skills in React + TypeScript.
• Deep experience with REST, WebSockets, gRPC, and real-time systems.
• Strong understanding of caching and state management (Redis, TanStack Query, Zustand, Redux).
• Hands-on experience with LLM tooling (LangChain, LlamaIndex, DSPy, Smolagents) and prompt engineering.
• Experience using AI-powered dev tools (Cursor, Copilot, etc.).

Nice to Have

• Background in anomaly detection, compliance systems, or workflow automation (Celery, Temporal, Cadence).
• Familiarity with rapid prototyping tools (v0.dev, Lovable).
• Strong product mindset with focus on usability and iterative delivery.
