About the RoleWe are looking for a solid backend engineer who can work across our existing PHP backend while helping us build the next generation of AI-powered product capabilities.
This is not a pure AI research role. We need someone who can ship production software, work with real customer data, build reliable backend systems, and apply AI/LLMs practically inside a SaaS product.
You will work on core backend development in PHP, build AI agents and automation workflows in Python, integrate LLMs and vector databases, and support data pipelines, ETL processes, and ML-driven product features.
The ideal candidate is a hands-on engineer who is comfortable maintaining existing systems while also building new AI-native capabilities from the ground up.

Responsibilities
- Build, maintain, and improve backend features in our existing PHP application.
- Develop AI agents and automation workflows using Python.
- Integrate LLMs such as OpenAI, Claude, Gemini, or similar models into product features.
- Build RAG-based systems using embeddings, vector databases, and document retrieval.




- Work with frameworks and tools such as LangChain, LlamaIndex, or similar AI orchestration libraries.
- Design APIs, backend services, background jobs, and data processing workflows.
- Build and maintain ETL pipelines to move, clean, transform, and structure data.
- Work with structured and unstructured data from CRMs, conversations, customer records, emails, websites, and third-party integrations.
- Implement prompt pipelines, tool/function calling, intent classification, memory, and agent workflows.
- Collaborate with product, engineering, and leadership to turn business problems into AI-powered features.
- Monitor, debug, and improve AI output quality, latency, cost, and reliability.
- Write clean, maintainable, testable code.
- Support integrations with third-party APIs and internal systems.
- Help modernize parts of the backend architecture over time.

Required Skills
- Strong backend devel
