AI Engineer - Agentic Systems (m/f/d)

Your Role

We’re looking for an experienced (Senior/Staff) AI Engineer (m/f/d) to help build the next generation ofagentic AI systems powered byLarge Language Models (LLMs) . You’ll be working at the intersection of reasoning, tool-use, and memory, designing intelligent agents that operate in complex environments, interact with APIs and structured data, and drive real‑world outcomes. This is a hands‑on role for someone who wants to go beyond prompt engineering, building robust decision pipelines andshipping product‑ready agents across bothtext and voice modalities .

AtActo , you’ll go beyond building chatbots and design full decision‑making systems across text and voice. You’ll shape how humans and AI collaborate in real‑world workflows, working on the frontier of agentic AI.

Your profile: What you need to succeed

• LLM Expertise: Strong experience building withLLMs (e.g., OpenAI, Claude, Mistral, open‑source models)
• Agentic Frameworks: Familiarity withagentic frameworks (e.g. LangChain)
• Programming Proficiency: Proficient inPython and modern ML tooling (e.g., Hugging Face, PyTorch, Ray, etc.)
• Tool Integration: Experience withtool integration , calling APIs, managing memory/state, or SQL query generation
• Voice AI: Experience working withvoice agents ,ASR , orTTS pipelines—or a strong willingness to learn them
• Startup Mindset: Comfortable in an iterative, fast‑paced product environment

Why Acto?

• Development Opportunities : Steep development opportunities without entrenched hierarchies.
• Culture: We are an ambitious team that wants to achieve a lot with Acto, but we don't take ourselves too seriously and like to have fun together, be it working together or at regular team events.

• Equipment : You will receive a state‑of‑the‑art hardware setup with a choice between Mac and Windows.

Your mission

• Design & Optimize Workflows: Design, implement, and optimizeagentic workflows using LLMs.
• Build Tool‑Using Agents: Create agents that interact with external APIs, databases, and environments.
• Develop Voice Agents: Work onvoice‑enabled agents , including pipeline design, transcription, and dialogue management.
• Integrate Memory & State: Implementretrieval, long‑term memory , andstate tracking into agent architectures.
• Deploy in Production: Collaborate with product teams todeploy agents in production.
• Evaluate & Improve: Design and runexperiments to evaluate agent performance, correctness, and hallucination rates
• Translate Product Needs: Turn high‑level product requirements into scalable, testable agentic features
