Applied AI Engineer – Search & Discovery at Opentable

Location: Kaunas, Lithuania (Hybrid, In office 2 days per week) With millions of diners, 60,000+ restaurant partners, and 25+ years of experience, OpenTable, part of Booking Holdings (NASDAQ: BKNG), is an industry leader helping restaurants thrive. Our technology enables restaurants to focus on what matters most—their team, their guests, and their bottom line—while empowering diners to discover and book the perfect restaurant for every occasion. Every employee at OpenTable has a tangible impact on what we build and how we build it. You’ll be part of a global team shaping the future of hospitality and discovery. We’re looking for a mid-level Applied AI Engineer to join our Diner Growth – AI Discovery team in Kaunas, based at Magnum Office Center. What we do We drive OpenTable’s growth by building systems that connect diners with restaurants across search engines and AI-driven discovery platforms. Our work combines search foundations—ranking, keyword coverage, and click-through optimization—with AI-driven approaches such as generative engine optimization (GEO), large-scale content systems, and platform integrations. We design and operate systems that generate and optimize high-quality content at scale (e.g., FAQs, restaurant descriptions), improve visibility across both search and AI surfaces, and integrate OpenTable into emerging platforms (e.g. MCP-powered experiences). Our approach is highly experimental and data-driven, with a strong focus on measurable impact.

What we’re looking for Experience with traditional SEO is a plus, but not required. We’re looking for self-driven engineers who take ownership, are excited about evolving AI systems, and can build scalable, high-impact products. You don’t need to know everything from day one.
