Staff Software Engineer

OAG is the essential intelligence partner transforming global travel. For nearly a century, we've been the foundation the travel industry builds on, trusted, proven, essential. Today, we're going beyond. We combine unmatched data quality, quantity and access with breakthrough technology and deep industry expertise to deliver what the industry truly needs: not just more data, but better answers. From real-time operational intelligence to strategic decision-making, we power the entire travel ecosystem, from airlines and airports to technology companies and financial institutions. We are actively embedding AI throughout our intelligence layer, combining nearly a century of proprietary data with the latest technology to deliver answers that were simply not possible before. We exist because travel moves the world, and we move travel. By transforming complexity into clarity and questions into answers, we give our partners the intelligence they need to thrive in an evolving world. For more information visit www.oag.com ABOUT THE ROLE: OAG Digital is the team turning our world-class data into a product-led growth engine: a unified experience where customers can discovery, try, pay and use on their own. We build the platform customers use to find, buy and use our data, and the intelligence products that turn that data into answers. This is the most senior individual contributor role on the technical side of Digital. Its purpose is to turn the Digital strategy into a technical strategy that delivers it: deciding what gets built, in what order and to what standard, so the business can sell what it has committed to sell. A decision taken in one team should still work in another, our promises to customers on access, security, reliability and cost should hold on every channel, and the hardest problems should get solved once. You’ll work across two areas. Core is the platform backbone: identity, auth, entitlements, billing, usage metering and the infrastructure everything else depends on. Intelligence is the layer above the data: AI-powered insights, predictive models built on Databricks and Snowflake, anomaly detection, and agentic features. The role is hands-on. You’ll write production code on the hardest parts of the platform while setting direction, reviewing designs and helping other engineers do better work. We care about UX as much as throughput, and we’re AI-native: tooling is part of how we develop, not an afterthought. This role can be worked remotely from anywhere in the UK only. Please note that we’re unable to offer visa sponsorship, so applicants will need the existing right to work in the UK. WHAT YOU’LL BE DOING • Design and build the hardest parts of the platform, hands on: how customers get to the right data and products, how that access is controlled, and what it costs us to serve. Stay close enough to the code that the design still holds once it’s built • Set the technical direction for problems that cross team boundaries: how customers are identified, what they’re allowed to use, how usage is measured and charged, and how existing customers and older systems move onto the new platform. Write the design down, get agreement, and stay with it through delivery so teams build to one approach rather than several • Set the standard for products built on AI and machine learning: define what a feature must do before it ships (show where its answer came from, be honest about how current the data is, fail predictably, be tested repeatably). Set the technical brief for data science teams, including how a model will be judged and the speed and cost it has to work within, and push back when a model isn’t the right tool • Work with the teams and partners outside Digital who build against your designs, including other parts of O
