* Build solutions using LangChain, LangGraph and related technologies
* Design and maintain data processing workflows and pipelines
* Integrate LLMs, external APIs, databases and other tools into AI-driven applications
* Deploy and operate applications in GCP and/or AWS
* Collaborate directly with senior engineers, architects and other members of the client’s technical team
* Participate in architecture and technical design decisions
* Write clean, maintainable and well-tested production code

Requirements

* Senior-level software engineering experience
* Excellent knowledge of Python
* Strong background in backend engineering and/or data engineering
* Proven experience developing production applications
* Experience with APIs, microservices, databases and distributed systems
* Experience with GCP and/or AWS
* Ability to design and implement complex systems independently
* Strong problem-solving and software architecture skills
* Professional working proficiency in English

Highly Desirable

Hands-on experience with one or more of the following:

* LangChain
* LangGraph
* LLM application development
* AI agents and multi-agent systems
* ReAct and agent-loop architectures
* Tool calling and agent orchestration
* RAG architectures
* Vector databases
* Production deployment of AI/LLM applications

Engagement

* Full-time engagement
* Long-term project
* Remote
* Direct collaboration with the client’s engineering team
* Senior engineers only
* Availability to start soon is preferred
