This is a fully remote position, open to applicants in Europe.
• Create agent-centric retrieval systems that are optimized for machine interaction rather than human search experiences.
• Construct systems in which LLMs methodically plan, query, refine, and reason over the outcomes.
• Develop ranking and retrieval strategies for multi-step, agent-led workflows that operate under real-world limitations.
• Propel applied research and set the technical agenda for retrieval and ranking systems.
• Design and enhance multi-stage retrieval architectures, which encompass query understanding, rewriting, reranking, and iterative retrieval.
• Formulate techniques for grounding LLMs in real-time web data at scale.
• Define and execute evaluation frameworks and metrics for agent-driven systems.
• Lead experimentation on embeddings, hybrid search, and reranking, transitioning methodologies into production.
• Assess relevance, latency, and cost trade-offs on a large scale.
• Collaborate with engineering teams to implement systems in high-throughput, low-latency settings.
• Take ownership of ambiguous challenges from start to finish and influence product and research trajectories.
• Provide mentorship to engineers and contribute to elevating the technical standards of the team.
• Over 8 years of experience in applied AI, ML, or software engineering.
• Demonstrated history of deploying ML or AI systems to production at scale.
• Extensive experience with search, retrieval, ranking, recommendation systems, or assistants.
• Strong knowledge of modern deep learning techniques, particularly transformers and embeddings.
• Familiarity with LLM-integrated or knowledge-intensive systems.
• Experience in designing evaluation frameworks and metrics for ML systems.
• Proficient programming skills in Python and at least one of Go, C++, or comparable languages.
• Capability to thrive in a dynamic, product-focused environment, exhibiting high ownership and autonomy.
• Experience with large-scale search or recommendation systems.
• Background in agentic AI systems, including agents, tool utilization, or autonomous workflows.
• Familiarity with RAG, multi-step retrieval, or tool utilization.
• Publications, open-source contributions, or similar indicators of technical expertise and impact.
• Must have authorization to work in the country of application and provide proof of employment eligibility.
• Competitive compensation.
• Opportunities for career advancement and learning.
• Flexibility and a sense of ownership.
• A collaborative and innovative workplace culture.
• Chance to engage in impactful AI projects.
