 Introduction

We are seeking a dynamic and self-sufficient full-stack engineer to own and lead the development of a FastAPI microservice integrated with an enterprise agentic AI platform. This role emphasizes full ownership and autonomy in driving work independently and delivering production-quality software from day one.

Required Skills & Qualifications

• 7+ years of full-stack software engineering experience.
• Expert-level proficiency in Python, with the ability to write clean, production-ready, type-safe code.
• Deep hands-on experience with FastAPI and Pydantic for building and maintaining microservices.
• Proficiency in front-end development using React, TypeScript, HTML, and CSS.
• 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, identify what needs to be done, and execute without heavy oversight.
• Strong written and verbal communication skills; able to collaborate effectively across engineering and AI teams.
• Prior work experience at the client or in the client's industry.

Applicants must be able to work directly for Artech on W2.

Preferred Skills & Qualifications

• 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.

Day-to-Day 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 for caching, persistence, and session management.
• 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 — balancing delivery velocity with long-term maintainability.
• 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.
