This role emphasizes full ownership of a FastAPI microservice integrated with an enterprise agentic AI platform. The ideal candidate is a self-sufficient full stack engineer with deep backend expertise who can identify scope, drive work independently, and deliver production-quality software. The position involves designing and delivering both front-end and back-end components with a strong emphasis on backend service ownership and collaborating with AI engineers to integrate AI-driven features.

Key Responsibilities:

Own the full lifecycle of a FastAPI microservice: design, implementation, testing, deployment, and ongoing maintenance

Build and expose robust, well-documented RESTful APIs using FastAPI and Python, enforcing data contracts with Pydantic

Develop front-end interfaces and components using React, TypeScript, HTML, and CSS

Integrate with relational and NoSQL databases including MongoDB, SQL, and Redis

Partner with AI engineers to incorporate LLM-driven features, agentic workflows, and AI model outputs into the microservice

Serve Node.js and/or Apache-backed services as part of a broader microservices ecosystem

Ensure secure, scalable, and maintainable architecture across all layers of the stack

Drive development across the full spectrum of service work: new feature development, performance optimizations, and technical debt remediation

Proactively identify technical debt, architectural gaps, and new workstreams, owning them through to completion

Implement observability and monitoring instrumentation to ensure operational health of owned services

Write clean, type-safe, production-grade Python code adhering to best practices and team standards

Requirements:

4+ years of full stack software engineering experience

Expert-level Python with clean, production-ready, type-safe code

Deep hands-on experience with FastAPI and Pydantic for building and maintaining microservices

Proficiency in front-end development: React, TypeScript, HTML, and CSS

Experience with Node.js and web server technologies (Apache or equivalent)

Strong database skills across multiple paradigms: MongoDB, SQL (PostgreSQL/MySQL), and Redis

Demonstrated experience building, consuming, and owning RESTful APIs in production environments

Experience working on or integrating with AI applications, familiarity with LLM-powered services, AI APIs, or ML-driven features

Self-directed and autonomous; able to own a service end-to-end, define scope, and execute without heavy oversight

Strong written and verbal communication skills

Experience with Elastic (ELK: Elastic, Logstash, Kibana)

Desired skills:

Experience with LangChain and/or LangGraph for building or integrating agentic workflows

Familiarity with vector databases (e.g., Elasticsearch, Pinecone, Weaviate) and RAG patterns

Understanding of LLM behavior, prompt engineering, and context management

Experience with LangSmith or similar LLM observability and tracing tools

Background in data pipelines, streaming, or batch processing

Experience in enterprise or financial services engineering environments
