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.

• 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, Type Script, HTML, and CSS
• Integrate with relational and No
  
  SQL 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 work streams, 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

• 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, Type Script, 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)

• Experience with Lang Chain and/or Lang Graph 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
