AI Engineer

Wanderlust App is a travel planning platform that uses grounded AI to build day-by-day itineraries from real city and cost data, then helps travelers live that plan offline on the ground through Trip Mode, and share it with a community of other travelers. We're looking for an AI Engineer to help build and improve the AI systems that power our itinerary generation and trip assistant features.

What you'll do

• Design, build, and maintain AI/ML systems that power itinerary generation, trip recommendations, and conversational planning features
• Develop and refine prompting strategies, retrieval pipelines, and grounding techniques to keep AI outputs accurate and useful
• Collaborate with product and engineering teams to integrate AI features into the core planning and Trip Mode experiences
• Evaluate model performance, build test harnesses, and iterate based on real user feedback and edge cases
• Monitor and improve latency, cost, and reliability of AI-powered features in production
• Work with structured city, cost, and travel data to ensure AI outputs stay grounded in real-world facts

What we're looking for

• Professional experience building and shipping AI/ML-powered features in a production environment
• Strong proficiency in Python and experience working with LLM APIs, embeddings, or retrieval-augmented generation (RAG) systems
• Solid understanding of prompt engineering, evaluation techniques, and strategies for reducing hallucination in AI outputs
• Experience working with structured and unstructured data pipelines
• Comfortable collaborating cross-functionally with product, design, and backend engineers
• Strong debugging and problem-solving skills, with a focus on shipping reliable, user-facing features

Nice to have

• Experience building consumer-facing AI products
• Familiarity with offline-first or mobile app architectures
• Background in travel, geospatial, or recommendation systems
