Job description

Build production-grade AI systems: Design, develop, and deploy robust ML- and LLM-based solutions for business-critical automation use cases.

  • Shape next-generation AI systems: Work on complex knowledge systems that go far beyond standard RAG setups, with a strong focus on correctness, grounding, and reliability.
  • Contribute to system architecture: Collaborate with senior engineers to design scalable architectures across LLM orchestration, retrieval systems, and agentic workflows.
  • Bridge research and production: Be part of a team that doesn't just apply existing solutions, but actively explores and develops new approaches to unsolved problems - and brings them into production.
  • Ensure quality and reliability: Implement evaluation frameworks, monitoring, and guardrails to ensure consistent system performance in real-world environments.
  • Collaborate across teams: Partner with product, engineering, and other stakeholders to deliver impactful AI solutions., Real ownership: You will directly shape core AI systems and technical decisions at a critical stage of our growth - with real responsibility from day one, not just execution.
  • High-impact problems: You will work on AI systems that operate in real, business-critical environments where correctness, reliability, and robustness truly matter.
  • Build beyond the standard: We are not interested in generic solutions. You'll work on complex knowledge systems and challenges that go beyond off-the-shelf RAG - often tackling problems that don't have established solutions yet.
  • Strong technical ambition: We care deeply about quality, pragmatism, and building AI that actually works in production - not just in demos.
  • Momentum & scale: You will join a fast-growing, well-funded company with strong traction and the opportunity to help define how modern AI systems are built in production.

Requirements

Strong AI/ML experience: You have solid experience building and deploying ML systems in production environments.

  • LLM expertise: You have hands-on experience with large language models, RAG pipelines, or orchestration frameworks.
  • Strong engineering skills: You are highly proficient in Python and modern ML tooling, and you write clean, maintainable, production-ready code.
  • Pragmatic mindset: You balance technical depth with a strong focus on delivering real-world impact.
  • Ownership mentality: You take responsibility for your work end-to-end, from development to deployment and monitoring.
  • Collaborative approach: You enjoy working in cross-functional teams and sharing knowledge with others.
  • AI-native way of working (plus): We believe AI is fundamentally transforming how software is built. Experience with agent-assisted coding, human-AI collaboration, and modern multi-engineer AI workflows is a strong plus.
