Wonderful enables enterprises to build, test, deploy, and monitor AI agents for their most complex needs, serving customers and employees seamlessly across voice, chat, email, and back-office systems in any language or cultural context.

Wonderful is growing at an unprecedented rate, backed by Tier 1 global investors who see, for the first time, AI delivering on its original promise. Our Voice AI agents run in real enterprise environments, handling hundreds of thousands of minutes of conversations each week, and are genuinely delightful to interact with - for customers and employees alike.

AI Engineers at Wonderful are experienced builders who go deep on integrations and agentic architectures, and act as the go-to experts for turning complex workflows into robust, production-grade agents.

This role is based on-site in our central Copenhagen office and involves regular work with customers. Depending on the project, you may spend part of the week embedded with a client team.

Role Overview

• Build & Deploy Agents: Build, test, and deploy AI agents on the Wonderful platform for enterprise customers.

• Prompts + Code: Write and design prompts, and implement the surrounding TypeScript logic and functions that guide AI agents across voice, chat, and email.

• Complex Integrations: Design and implement more complex integrations and agentic loops - combining multiple APIs, data sources, and tools to solve non-trivial customer workflows.

• Customer Engineering: Collaborate closely with Account / Program Management and enterprise customers to understand needs and existing workflows, and turn them into scalable AI solutions.

• Quality & Reliability: Deliver production-ready solutions with proper error handling, logging, and monitoring; adapt quickly to shifting priorities and challenges.

• Collaboration with Agent Engineers: Partner with Agent Engineers on day-to-day delivery, helping unblock harder technical problems and spreading best practices.

Requirements

• Education: Bachelor’s degree (or higher) in Computer Science or a related STEM field.

• Language: Excellent English, written and spoken + Native Danish Speaker

• Experience: 2–6 years of software development experience (ideally backend or backend-leaning full stack).

• Networking & APIs: Strong understanding of networking, HTTP, REST/gRPC APIs, and authentication mechanisms.

• Integration Skills: Ability to learn complex customer systems quickly and translate them into technical solutions and robust integrations.

• AI & Agentic Workflows: Comfort working with LLMs, prompts, and agentic workflows (prompts + TypeScript + tools); prior AI/ML or LLM experience is a plus.

• Mindset: A flexible, problem‑solving mindset with a passion for working under pressure in a customer-facing environment; bonus points for startup experience.
