Job description

Velocity Tech Partners are hiring a Senior Python Engineer to join a high-performing team building cutting-edge agentic AI platforms for enterprise clients.

This is a senior-level role focused on designing and delivering production-grade AI systems using modern LLM orchestration frameworks — not ML research.

You’ll work across complex client environments, helping organisations deploy intelligent, autonomous systems that drive real operational impact.

What you’ll be doing

• Design and build agentic AI platforms using Python and modern AI frameworks
• Architect LLM orchestration using tools such as LangGraph, CrewAI, AutoGen and similar technologies
• Build and scale multi-agent systems with tool use, memory, planning, and workflow execution
• Design and implement RAG pipelines over enterprise data sources
• Integrate agentic systems into client environments (APIs, data platforms, SaaS tools, enterprise systems)
• Deploy and manage workloads in Kubernetes across cloud, on-prem, and hybrid infrastructures
• Design robust, scalable, and secure production architectures
• Work directly with clients and stakeholders to translate business problems into technical solutions

What we’re looking for

• 8+ years’ experience as a Senior Software Engineer (Python-focused)
• Strong track record building production-grade backend systems
• Proven experience delivering agentic AI / LLM-based systems in production
• Hands-on experience with RAG pipelines and enterprise data integration
• Strong distributed systems and architecture skills
• Experience deploying workloads in Kubernetes
• Cloud experience (AWS / Azure / GCP)
• Comfortable working in fast-paced, ambiguous, client-facing environments
