• Develop AI assistants, agents, chatbots, document-processing systems, and workflow automations.
• Implement prompt management, structured outputs, tool calling, retrieval-augmented generation, and AI evaluation workflows.
• Create and maintain vector-search and knowledge-retrieval systems.
• Connect AI systems with CRMs, databases, communication tools, and third-party APIs.
• Implement authentication, role-based access control, and multi-tenant SaaS architecture.
• Monitor and optimize AI accuracy, latency, token usage, reliability, and operating costs.
• Design database schemas, write migrations, and optimize queries.
• Create automated tests and troubleshoot application and AI-related failures.
• Participate in code reviews and maintain strong engineering standards.
• Own assigned features from requirements and architecture through deployment and production support.
• Work directly with product, operations, and business teams to convert operational problems into scalable software.

• Hands-on experience integrating LLM APIs such as OpenAI, Anthropic, Gemini, or equivalent.
• Experience building at least one working AI-enabled application used by real users or business teams.
• Understanding of prompt engineering, structured outputs, function/tool calling, embeddings, and vector search.
• Experience implementing retrieval-augmented generation using business documents or proprietary data.
• Ability to test AI output quality and address hallucinations, security risks, latency, and cost.
• Strong experience with REST APIs and third-party system integrations.
• Experience with PostgreSQL or another relational database.
• Understanding of authentication, authorization, data security, and role-based access control.
• Proficiency with Git, GitHub, code reviews, and pull-request-based development.
