About the Role

We are looking for a Senior Full Stack AI Engineer with 7+ years of software development experience. The ideal candidate should have strong experience in Python, PostgreSQL, React, and AI/LLM development.

The candidate will build a new AI product from the beginning, work closely with the leadership team, and later guide a small team of developers. This is a hands-on role, so the candidate should be comfortable coding daily and handling production issues.

Key Responsibilities

• Build the AI agent backend using Python and FastAPI.

• Work with LLMs, including prompts, tool/function calling, and structured outputs.

• Design and maintain PostgreSQL databases, queries, indexes, and migrations.

• Build user interfaces using React and TypeScript.

• Integrate the AI agent with internal APIs and third-party services.

• Use AI coding tools such as Claude Code, Cursor, or GitHub Copilot to improve development speed and productivity.

• Guide and mentor 1–3 developers through code reviews, planning, and technical guidance.

• Make technical and architecture decisions and explain them clearly to product and leadership teams.

• Set up and maintain testing, CI/CD, logging, and monitoring.

• Monitor the production system and handle technical issues and incidents.

• Track AI performance, response quality, speed, and usage costs.

• Improve prompts and AI logic as models and requirements change.

• Follow secure coding practices and protect customer and personal data.

• Continue developing new features and improvements after the product goes live.

Required Skills

• 7+ years of professional software development experience.

• 1–2+ years of experience building and supporting AI/LLM features in production.

• Strong experience with Python and backend API development.

• Strong knowledge of PostgreSQL, database design, SQL, indexing, and performance tuning.

• Good experience with React and TypeScript.

• Strong understanding of LLMs, prompt design, tool/function calling, retries, rate limits, and handling incorrect AI responses.

• Experience using AI coding tools such as Claude Code, Cursor, or Copilot.

• Experience leading or mentoring developers while continuing to code hands-on.

• Experience supporting production applications, including monitoring, incident handling, and root-cause analysis.

• Good written and spoken English.

Preferred Skills

• Experience with RAG, embeddings, and pgvector.

• Experience with LangGraph, Claude Agent SDK, or MCP.

• Experience with LLM testing, monitoring, and cost management.

• Knowledge of Microsoft Azure, Docker, and CI/CD.

• Experience with multi-tenant SaaS applications.

• Experience in staffing, HR tech, payroll, or workforce management.

• Knowledge of SOC 2 or similar security and compliance standards.
