Senior AI Engineer

Airbnb was born in 2007 when two hosts welcomed three guests to their San Francisco home, and has since grown to over 5 million hosts who have welcomed over 2 billion guest arrivals in almost every country across the globe. Every day, hosts offer unique stays and experiences that make it possible for guests to connect with communities in a more authentic way. The Community You Will Join: The Quality Platform team is at the heart of Airbnb’s mission to provide a seamless, high-quality experience for millions of hosts and guests. We don’t just find bugs — we build the infrastructure that prevents them. Our team sits at the intersection of Mobile Infrastructure, Developer Experience, and Applied AI. We empower thousands of engineers across Airbnb to ship with confidence by building high-scale platforms, AI-driven automation, and fault-tolerant systems. You will join a group of high-impact engineers who value craft, operational excellence, and the challenge of navigating one of the world’s most complex mobile codebases. The Difference You Will Make: As a Senior IOS Software Engineer, you will play a key role in evolving our Quality Platform. You will bridge the gap between product engineering and infrastructure, ensuring that our IOS codebase remains highly testable and resilient as it scales. In this role, you will: * Build AI-Native Tooling: Move beyond traditional automation by implementing AI-driven agents that optimize our CI/CD pipelines and provide intelligent feedback to developers. * Enhance Developer Velocity: Identify and resolve systemic bottlenecks in the development lifecycle, allowing teams to move faster without compromising quality. * Advocate for Quality by Design: Work directly with product teams to guide architectural decisions, ensuring that new features are modular and testable from the first line of code. * Ship High-Scale Infrastructure: Own the development and maintenance of frameworks used by hundreds of engineers across Airbnb, ensuring they are performant, reliable, and easy to use. A Typical Day:  * Hands-on Development: Write high-quality, performant Swift code to extend testing frameworks and build AI-powered developer tools, leveraging LLMs to accelerate development workflows * Technical Ownership: Take ownership of key components of our Automated Quality Platform, ensuring operational excellence and high availability (24x7) of our testing infrastructure. * Design & Review: Participate in deep-dive design reviews for new IOS features, providing expert guidance on modularity and testability patterns. * Applied AI: Implement LLM-based solutions for smart test orchestration, test case generation, and autonomous test discovery to reduce CI feedback loops. * Cross-Functional Collaboration: Partner with Product and Mobile Infrastructure teams to align platform capabilities with the needs of the broader engineering org. * Mentorship: Review code and provide technical guidance to peers, fostering a culture of commitment to craft and engineering rigor. Your Expertise: * Experience: 5+ years of professional IOS development experience (or 2+ years with a PhD) in a fast-paced, high-growth tech environment. * Technical Mastery: Strong proficiency in Swift and the IOS SDK. You have a solid understanding of modern IOS architecture and the Xcode build lifecycle. * Infrastructure Experience: Demonstrated expertise in building or maintaining test automation frameworks (e.g., XCUITest) at scale. * CI/CD & Tools: Familiarity with CI/CD orchestration and a passion for building tools that improve the developer experience. * AI Curiosity: A strong interest or hands-on experience in leveraging AI/LLMs to solve engineering productivity or quality challenges. * Problem Solving: Proven ability to navigate complex, ambiguous codebases and implement best-in-class solutions. * Communication: Excellent communication skills with the ability to facilitate technical discussions across cross-functional teams.

We’re a new team building AI-assisted tools to make Datadog developers more effective, by autonomously generating tests, fixing bugs, and improving performance. We’re looking for a product-minded generalist to help us quickly define and ship products that make all Datadog customers 10x developers. At Datadog, we place value in our office culture - the relationships and collaboration it builds and the creativity it brings to the table. We operate as a hybrid workplace to ensure our Datadogs can create a work-life harmony that best fits them.   WHAT YOU’LL DO: * Work closely with our users, designers, PMs, and data scientists on cutting edge and delightful LLM-based agents. * Work on prompts, evals, and agent tools for working with code, and on the engineering to productionize these systems and integrate them with Datadog products. * Prototype and see what works well in the real world, iterate closely with our users, and then ship. * Follow the latest research on LLM prompting, agents, and code editing. * Work with other Datadog teams to expand capabilities, for example integrating with the Datadog IDE extensions to deliver a CoPilot-like assistant, or Dynamic Instrumentation to collect more runtime data from production and pre-production environments.   WHO YOU ARE: * You’re a backend engineer with at least 5 years of professional experience (Go, Java, Python) who values code simplicity and performance. You’ve shipped software that uses LLMs to production. * You are passionate about Generative AI and its ability to help software engineers be more productive. * You have relevant experience with Large Language Models, large-scale systems and data sets, machine learning, or adjacent fields. * You are a great community ambassador and can drive hard technical conversations towards a pragmatic solution. * You want to work in a fast, high-growth startup environment that respects its engineers and customers. * You have experience writing developer tools (such as IDEs, static code analysis tools, or compilers). * You have demonstrated ability to use AI coding tools in day-to-day workflows and validate, critique, and refine AI-generated output. * Bonus: you’re motivated to push the boundaries of how AI can improve software engineering best practices and contribute to building AI-enabled products. Datadog values people from all walks of life. We understand not everyone will meet all the above qualifications on day one. That's okay. If you’re passionate about technology and want to grow your skills, we encourage you to apply. Benefits and Growth:  * New hire stock equity (RSUs) and employee stock purchase plan (ESPP) * Continuous professional development, product training, and career pathing * Intradepartmental mentor and buddy program for in-house networking * An inclusive company culture, ability to join our Community Guilds (Datadog employee resource groups) * Access to Inclusion Talks, our Internal panel discussions * Free, global mental health benefits for employees and dependents age 6+ * Competitive global benefits Benefits and Growth listed above may vary based on the country of your employment and the nature of your employment with Datadog.   #LI-Hybrid ---------------------------------------------------------------------------------------------------------------------------------- About Datadog:  Datadog is the leading observability and security platform for the AI era, providing businesses with unified visibility across the technology stack to manage complexity at scale.
