Full Stack Developer - Python/Flask/FastAPI & LLM & React

Full Stack Engineer

SFO, CA- Hybrid (Tuesday to Thursday in office)

6+ months with high possibility of extension

Job Description:

Key Responsibilities:

• System Architecture & Database Design: Architect scalable, low-latency backend systems capable of handling massive datasets and live risk-data updates. Design highly optimized database schemas (SQL/NoSQL) and data orchestration pipelines tailored for FRM automation.
• API & Service Orchestration: Develop and manage RESTful APIs, GraphQL, and high-performance real-time communication layers (WebSockets/gRPC-web). Implement microservices architecture and Model Context Protocols (MCPs) to securely connect AI agents with internal enterprise data.
• Advanced AI & LLM Integration: Design, integrate, and deploy production-ready LLM systems using providers like OpenAI and Anthropic. Build sophisticated backend workflows using AI agent frameworks (Lang Graph, CrewAI), function calling, and complex tool-use patterns to automate business logic.
• Full-Stack Execution & Frontend Delivery: Translate high-fidelity Figma designs or rapid prototypes into pixel-perfect, scalable, and secure React layouts. Manage complex asynchronous workflows using Redux + Sagas or Zustand, while implementing TanStack Query for modern server-state synchronization.
• Performance & AI Observability: Build resilient AI systems by implementing AI Observability (e.g., LangSmith, Opik), hallucination detection, and retry logic. Optimize end-to-end performance to ensure frequent real-time updates do not trigger unnecessary UI re-renders, maintaining a fluid user experience even under high data loads.
• AI-Driven Development: Lead by example in using AI-augmented coding workflows, leveraging tools like Cursor, Codex, and GitHub Copilot to accelerate cross-stack feature delivery, refactor legacy logic, and eliminate boilerplate.

The Mission The Financial Risk Management (FRM) team ensures the integrity of our platform through real-time monitoring, complex data visualization, and AI-driven automation. We are looking for a Senior Full-Stack Engineer (Backend-Focused) to architect the core data systems and service layers that power our platform, while seamlessly tying them into high-velocity user interfaces. You will build highly scalable infrastructure, orchestrate complex APIs, integrate GenAI capabilities into our backend workflows, and deliver polished frontend experiences. The Role: Architecting Intelligent, End-to-End Infrastructure

You will own the system architecture for our FRM compliance and automation tools. This means moving fluidly across the entire stack-designing databases, building robust microservices, integrating Model Context Protocols (MCPs) for AI agents, and hardening interactive dashboards to handle live risk-data updates with ultra-low latency. You are a high-velocity engineer who embraces the future of software development, treating data, APIs, and interfaces as a single cohesive product.

Required Qualifications

• 7+ Years of Engineering Experience: A deep background in system design, database architecture, and scaling enterprise-grade backend services, with a recent pivot toward full-stack delivery and AI-augmented workflows.
• Core Stack Mastery: Deep proficiency in Python (Flask/FastAPI) and Node.js to develop performant service layers, combined with a strong command of React and TypeScript to build production-grade interfaces.
• Real-Time & Protocol Expertise: Expert-level knowledge of RESTful APIs, service orchestration, WebSockets, and gRPC-web to ensure data streams perfectly sync between backend nodes and client apps.
• State & Data Lifecycle Strategy: Expert implementation of high-throughput databases, caching layers (e.g., Redis), and modern state management strategies (TanStack Query, Zustand, or Redux) to handle heavy data mutations seamlessly.
• AI Tooling & LLM Orchestration: Hands-on experience with LLM orchestration frameworks (LangChain, LlamaIndex, Smolagents, DSPy) as well as advanced prompt engineering. Mastery of the Cursor code editor (indexing, composer, and chat features) to maintain elite velocity.

Nice to Have

• Uber Ecosystem: Prior experience at Uber or deep familiarity with our internal developer ecosystem, internal data pipelines, and platform services.
• Workflow Domain: Background in building systems for anomaly detection dashboards, compliance tools, or complex workflow-driven automation platforms (e.g., Celery, Cadence, Temporal).
• Rapid Prototyping Fluency: Familiarity with design-to-code or AI prototyping sandboxes (like Lovable or v0.dev) to quickly map out internal tools before building them into permanent architecture.
• Product Mindset: Proven focus on delivering measurable user value, using stakeholder feedback for iterative improvement, and treating technical components as a product to ensure usability, quality, and adoption.

The Tech Stack

• Backend Core: Python (FastAPI, Flask), Node.js, Microservices, MCP (Model Context Protocol).
• Frontend Core: React, TypeScript, Fusion.js (Uber’s Framework).
• AI & LLM Tools: Cursor, GitHub Copilot, LangGraph, CrewAI, LangSmith/Opik, Lovable, v0.dev.
• State & Data: Redux + Sagas, TanStack Query, Zustand, Context API, WebSockets, gRPC-web, GraphQL, Redis, SQL/NoSQL.
• Design & UI: BaseUI design system, Styletron (CSS-in-JS), Figma, Tailwind CSS.
