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
