Lead AI Engineer

About IXOPAY

IXOPAY is the enterprise-grade global payment infrastructure platform built for the era of agentic commerce. We equip merchants and enterprises with AI-driven intelligence, payment orchestration, advanced tokenization, and the tools to optimize every stage of the payments journey.

From intelligent routing and compliance to customizable modules and enterprise-scale orchestration, IXOPAY helps businesses integrate faster, improve payment performance, and expand globally with confidence.

At IXOPAY, our people are our greatest strength. Our collaborative culture is built on shared values that guide how we work, innovate, and support our customers.

About the Role

We're looking for a Lead AI Developer to define and build the AI capabilities that will shape the future of IXOPAY.

This is a greenfield leadership role with broad technical ownership. You'll lead the design and delivery of AI-powered products while embedding AI across our engineering organization—from intelligent developer tooling to customer-facing agents and autonomous payment workflows.

Working closely with Product and Engineering, you'll establish our AI architecture, guide technical direction, and help build the team that delivers the next generation of AI-driven payment technology.

What You'll Do

• Design, build, and deploy production-ready AI agents and multi-agent systems.

• Define the architecture for AI-powered products, including retrieval, memory, orchestration, and human-in-the-loop workflows.

• Develop evaluation frameworks to measure quality, reliability, safety, latency, and overall model performance.

• Implement AI guardrails, observability, and monitoring to ensure secure and responsible AI deployments.

• Build intelligent workflows that automate onboarding, payment optimization, fraud detection, and operational decision-making.

• Partner with Product and Engineering teams to identify high-impact AI opportunities across the platform.

• Lead AI delivery from concept through production, balancing innovation, quality, scalability, and cost.

• Mentor engineers, establish engineering standards, and help grow IXOPAY's AI capability.

What You'll Bring

Required

• Extensive software engineering experience, with significant hands-on experience building production AI, machine learning, or agentic AI systems.

• Proven experience deploying LLM-powered applications used by real customers at production scale.

• Strong Python development skills with a focus on clean, maintainable, and well-tested code.

• Experience designing evaluation frameworks for AI systems, including quality measurement, regression testing, and model validation.

• Experience building AI agents using modern frameworks such as LangGraph, LangChain, or similar technologies.

• Strong understanding of retrieval-augmented generation (RAG), vector search, prompt engineering, and agent orchestration.

• Experience implementing AI safety practices, including guardrails, prompt injection protection, and human oversight.

• Familiarity with cloud AI platforms such as AWS Bedrock, Azure AI Foundry, or Google Vertex AI.

• Excellent communication skills and the ability to lead technical direction across cross-functional teams.

Preferred

• Experience in payments, FinTech, or other regulated industries.

• Experience scaling AI platforms or engineering teams in a fast-growing environment.

• Familiarity with LLM observability tools such as LangSmith, LangFuse, or Arize.

• Experience with fine-tuning strategies and understanding when they provide value over retrieval-based approaches.

• Contributions to open-source AI or machine learning projects.

Our AI Stack

While we're always evolving, our current technology stack includes:

• Foundation models including Claude via cloud AI platforms

• LangGraph, LangChain, and the Model Context Protocol (MCP)

• AWS Bedrock and Azure AI Foundry

• Python and TypeScript

• Vector databases and modern RAG architectures

• LangSmith, LangFuse, Arize, and Datadog for evaluation and observability

Why Join IXOPAY?

AI is central to our product strategy—not an experiment or side project.

As Lead AI Developer, you'll have the opportunity to shape both our internal engineering practices and the AI-powered experiences we deliver to customers. You'll work on technically ambitious challenges at the intersection of AI, distributed systems, and enterprise payments while helping define the future direction of the company.
