We’re seeking a driven AI Engineer to join one of the fastest-growing legal tech companies in Europe as we expand our core AI team delivering ‘Marie’, our AI phone assistant.

This role focuses on applied generative AI for voice products in a production environment, building and extending voice based systems systems through telephony systems, agentic workflows, and many further AI features used directly by lawyers.

Reporting to the AI Lead, you’ll work hands-on from architecture to implementation, collaborating with the Head of Engineering and product teams to ship reliable AI functionality while improving our voice and AI infrastructure, observability, and evaluation workflows.

For an engineer with practical experience building and deploying generative voice AI systems, this is an opportunity to take technical ownership of Marie, ship quickly, and shape how AI evolves across the company.

Your Challenge and Opportunity in This Role

You’ll help define how AI is built and shipped in a fast-moving product environment. As a core AI Engineer, you’ll turn modern generative AI techniques into production-ready systems that deliver real value to users.

Your primarily goal will be to maintain and expand our Phone AI system. Expect strong technical ownership, fast iteration, and a clear focus on building practical AI systems that improve productivity for law firms.

Tasks

AI Strategy & Implementation:

Architect and implement production-ready generative voice AI solutions within our product suite
Develop voice-based AI systems, integrating speech technologies such as ASR/STT and TTS into conversational workflows
Design and optimize real-time voice agent workflows, balancing latency, reliability, and conversational quality
Architect and implement production-ready generative AI and LLM-based solutions within our product suite to integrate our voice solution from end to end
Implement evaluation, testing, and observability for AI systems to ensure reliability and continuous improvement
Establish best practices for AI development, testing, and deployment across products
Handle AI development hands-on as a core technical contributor within a small, fast-moving team where engineers own problems end-to-end and ship quickly

Cross-functional Collaboration:

Work closely with product, design, and engineering teams to integrate AI capabilities into real product workflows
Translate complex AI concepts into practical product features and communicate them clearly to both technical and non-technical stakeholders

Requirements

Technical Expertise:

Extensive hands-on experience building and deploying generative AI systems in production
Strong experience building voice-enabled AI systems, including integration with ASR/STT and TTS technologies
Practical experience designing and deploying agentic systems or AI agents in production
Experience building real-time conversational AI systems, including streaming interactions and low-latency voice pipelines
Strong experience with RAG architectures (embeddings, retrieval, ranking)
Experience with LLM observability and evaluation tools (e.g., LangSmith, Langfuse) and designing evaluation pipelines for LLM systems
Strong programming skills in Python and solid software engineering practices
Experience designing LLM systems beyond simple API integrations, including retrieval pipelines, orchestration logic, and tool/agent workflows
Experience implementing AI features in real product environments, not purely research or academic settings
Ability to translate modern AI techniques into reliable, user-facing product functionality

Requirements:

You must be located in the CET -2/+2 zone for this role!
You must have at least 4 years of professional experience in AI
You must have deployed AI systems such as RAG pipelines or agentic systems into production
