• Develop and maintain backend services and REST/GraphQL APIs (Node.js, Python, PHP/Laravel, or Java) that power automation workflows.
• Build simple internal tools, admin panels, and dashboards (React/Vue/HTML-CSS-JS) for monitoring and controlling automations.
• Design and implement AI-agent-driven workflows using LLM APIs, prompt engineering, and agent frameworks to automate judgment-based orunstructured tasks.
• Apply RAG and vector-search techniques where automations need to reason over internal documents or data.
• Work with MySQL/PostgreSQL/MongoDB and message queues for data validation, state management, and event-driven automation.
• Use Git, CI/CD pipelines, and containerization to package, test, and deploy automation workflows reliably.
• Debug and troubleshoot automation and integration failures, and drive root-cause analysis across the stack.

Requirements

Automation & RPA

• Hands-on experience with workflow/iPaaS automation tools such as n8n, Zapier, Make, or Power Automate.
• Exposure to RPA platforms (UiPath, Automation Anywhere, Blue Prism) is a plus.
• Good understanding of REST/GraphQL APIs, authentication/authorization, and third-party integration patterns.

Frontend / Internal Tooling

• Comfortable with HTML/CSS fundamentals for quick internal UI work.

Agentic AI / LLM

• Practical understanding of LLM APIs (OpenAI, Anthropic, or similar), prompt engineering, and function/tool calling.
• Familiarity with agent frameworks such as LangChain, LangGraph, CrewAI, or AutoGen for building autonomous or semi-autonomousworkflows.
• Basic understanding of RAG patterns and vector databases (Pinecone, Weaviate, pgvector, or similar).
• Ability to evaluate when an AI agent is the right tool versus deterministic automation, and to validate AI-generated output for quality and safety.

DevOps & Cloud

• Working knowledge of Git, branching, merge requests, and CI/CD pipelines (GitLab CI, GitHub Actions, or Jenkins).
• Exposure to Docker/containerization; cloud platform experience (AWS, Azure, or GCP) is a plus.
