AI Engineer

AvantStay is a technology platform behind a large portfolio of vacation rentals, and they are seeking an AI Engineer to contribute to their AI systems. The role involves shipping LLM systems, maintaining accuracy, and collaborating with cross-functional teams to create effective solutions.

Responsibilities:

• Ship LLM systems that tightly integrate with our infrastructure and knowledge bases: PostgreSQL, Clickhouse, Kafka, APIs, MCPs
• Maintain autonomous and human-in-the-loop systems and ensure uptime and accuracy
• Interact with users and stakeholders to understand their problems and design solutions
• Stay up-to-date with the latest trends in LLMs and applied AI practices
• Collaborate with a cross-functional team of engineers, product managers, designers, and other members to create a product that solves actual problems
• Update existing systems to be agent-accessible. Some % of the work is refactoring APIs that were never meant to be called by an LLM - be ready for that
• Build the patterns and tooling that let the rest of engineering deploy agents faster

Requirements:

• Shipped at least one LLM-powered system used by real users (internal or external) that took actions in a real system
• Can talk specifically about evals, retrieval shape, observability of agent traces, and handling non-determinism in a system business operators depend on
• Strong software engineering fundamentals - databases, Kafka, GraphQL/REST, Kubernetes, AWS
• Proficient in TypeScript
• Product instincts. You can sit with a stakeholder for an hour and walk out with a concrete idea of what to build
• Fluent in English
• OSS contributions to the AI ecosystem. Examples: LangGraph, PydanticAI, DSPy, instructor, or similar
• Functional programming background. Preference to use functional paradigm
• High-throughput data systems experience (Kafka, ClickHouse, Postgres at scale)
