About the role

Backend/Agent Engineer – Python, AI Agents, LangGraph, MCPWe are seeking an experienced Backend/Agent Engineer to join our team, specializing in designing, developing, and maintaining robust backend systems for AI-driven agent platforms. In this role, you will focus on architecting scalable, reliable backend services and integrating advanced AI agents using Python and frameworks like LangGraph and MCP (Model Composition/Coordination Platform). You will work closely with multidisciplinary teams to deliver intelligent, context-aware solutions that power real-world applications.
Key Responsibilities: Backend System Development: Architect, implement, and maintain scalable backend services and APIs using Python (FastAPI, Flask, Django) to support AI agent operations. AI Agent & MCP Integration: Develop, deploy, and orchestrate autonomous AI agents, and leverage MCP to coordinate multiple AI models and agent workflows, ensuring seamless interoperability and orchestration. Agent Orchestration & Workflow: Utilize frameworks like LangGraph and MCP to design, compose, and manage complex agent workflows, multi-agent coordination, and state management. System Integration: Integrate external data sources, third-party APIs, vector databases, and machine learning models to enhance agent capabilities. Performance & Reliability: Optimize system performance, ensure high availability, and implement robust logging, monitoring, and error-handling solutions. Collaboration: Work cross-functionally with front-end developers, data scientists, and product teams to translate requirements into technical designs and deliverables. Security & Compliance: Implement best practices for data security, privacy, and compliance in all backend operations.
Required Skills & Qualifications: Strong experience with backend Python frameworks (FastAPI, Flask, Django), RESTful API design, and database management (SQL/NoSQL).Proven expertise in integrating and orchestrating AI agents, LLMs, or multi-agent systems in production environments. Hands-on experience with MCP (Model Composition/Coordination Platform) for coordinating and managing AI models and agent workflows. Familiarity with agent workflow orchestration tools such as LangGraph. Experience with containerization (Docker), CI/CD pipelines, and cloud infrastructure (AWS, GCP, Azure).Knowledge of vector databases, data pipelines, and scalable distributed systems. Excellent problem-solving abilities, attention to detail, and communication skills.
Preferred: Background in designing backend architectures for AI or data-intensive applications. Experience with knowledge graphs, RAG pipelines, or advanced agent coordination. Open-source contributions or experience with modern agent/LLM frameworks, MCP, or similar platforms.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
