Transform Financial Services with Cutting-Edge AI
Avanti Recruitment is partnering with an ambitious Series A fintech startup that's revolutionizing how financial institutions operate. Our client has secured £6M+ from a top-tier VC and is building the future of AI-powered business process automation.

The Opportunity
Join as a founding team member and help build world-class AI agents that transform manual, weeks-long financial processes into intelligent, automated workflows. You'll be developing sophisticated multi-agent systems from entry-level automation to expert-level autonomous decision-making.
You'll be architecting the cognitive intelligence behind agent systems that operate in highly regulated environments, processing complex financial data and making critical business decisions.

What You'll Build

  • Advanced agentic architectures with orchestrator-managed specialized sub-agents
  • Machine learning algorithms that increase agent autonomy and reduce human input
  • Collaborative learning systems where agents share knowledge and improve collectively
  • Fine-tuned models optimized for complex financial workflows
  • Event-driven distributed systems handling sensitive data at enterprise scale
The Tech Stack
  • AI/ML: Multi-agent frameworks, fine-tuning, reinforcement learning, advanced RAG
  • Platform: AWS serverless, event-driven architecture, microservices
  • Languages: Python, with modern ML libraries (PyTorch, TensorFlow)
What They're Looking For
  • 5+ years developing AI/ML systems beyond basic integration
  • Deep understanding of agent architectures and distributed AI systems
  • Computer science fundamentals - algorithms, system design, software engineering
  • Startup mindset - comfortable with rapid iteration and technical trade-offs
This is an incredible opportunity to join a well-funded startup at a truly exciting time. You'll work alongside brilliant engineers, tackle fascinating technical challenges, and build technology that transforms an entire industry.
