AI Agent Engineer

About Ace Waves

AI is rebuilding customer service from the ground up. At Ace Waves, we’re building an AI agent platform that handles real customer conversations end to end for leading consumer brands.

We started in stealth and are now a fast-growing, well-funded startup with a growing customer base across Europe. We’re headquartered in Kaunas, with GTM hubs in London and Poland, and we’re driven by a shared commitment to excellence, ambition and speed.

Our co-founders, Antanas Bakšys, Ringaudas Kalinauskas and Lukas Mikuckis, previously founded SearchNode, which was acquired in 2022. They are industry veterans and pioneers in agentic AI, with a clear goal for Ace Waves: to become a global top vendor and the next Lithuanian unicorn. As an early team member, you’ll work closely with them.

The team

Our forward-deployed agent engineering team builds, integrates and manages multi-agent AI systems for enterprise customers. The team works at the intersection of customer engineering and AI product management. It builds complex agent workflows and integrations that change how companies run support at global scale.

What you’ll do

• Build, maintain and continuously improve production-grade multi-agent AI systems running in live customer support at scale.

• Lead or join client workshops to map support processes and turn them into executable agent procedures.

• Implement and test integrations with customer platforms such as Zendesk, Intercom, Shopify and internal CRMs.

• Monitor performance, debug live environments, and keep deployed agents reliable and safe.

• Document solutions clearly and explain technical details to clients and internal teams.

• Work with the GTM team so that technical delivery matches customer business goals, and share implementation insights that help win new customers.

What this looks like in practice

• Building and launching a complete multi-agent orchestration for a major brand that automates refunds, order status, delivery questions and other customer issues at scale.

• Working directly with the customer to explain system logic, coordinate maintenance, and plan improvements based on live performance data.

• Joining customer integration strategy sessions and sharing best practices with the GTM team to improve future rollouts.

• Strong logical and analytical thinking: you find structure in complex systems

• You learn fast and deliver results when conditions change

• Experience building technical projects or digital products, with code, no-code, AI or other tooling

• A self-directed mindset, strong ownership and a bias for action

Nice to have

• Knowledge of APIs and integrations with enterprise platforms

• Experience in customer support or service operations
