Engineering Lead - Wise AI Assistant Platform

The team you will join: Wise Assistant

We're building Wise Assistant, a conversational AI that will become a central interface for managing money on Wise. This is a super visible and highly ambitious AI project. The team is at the forefront of applied AI at Wise: we already automate 40% of customer support chats with LLMs, and we're pushing further — voice automation, agentic AI and becoming the conversational operating system at Wise. Part product, part R&D, always production-grade at scale.

• Production AI at scale: not a PoC, not an experiment. Real LLM systems serving millions of customers, with real stakes.
• R&D with impact: you'll read papers, prototype new approaches, and ship them to production.
• In Budapest: one of very few opportunities to lead large-scale AI engineering locally.

You will

• Lead a small, senior engineering team building production LLM systems.
• Shape the technical vision for AI at Wise: architecture, evaluation, and how we integrate the latest research into production.
• Partner closely with embedded Data Science, PM, Analyst and Prompt Engineering functions.
• Stay close to the latest tech (expect hands-on work on system design and architecture).
• Be a thought leader on AI engineering at Wise.

You bring

• 2+ years leading engineering teams, ideally including senior engineers.
• Strong, hands-on technical experience in OOP languages (Java) and modern technology stacks such as REST APIs, microservices, distributed systems and CI/CD pipelines.
• Solid understanding of LLM engineering: RAG architectures, vector databases & embeddings, prompt/context engineering, orchestration patterns, tool use, evaluation methods and guardrails/safety approaches.
• Passion for AI: you follow the space, and want to push boundaries on a production system at scale.
• Excellent collaboration skills across functions and teams.

• TypeScript
• Deeper AI fundamentals (e.g. transformer architectures, fine tuning)
