We offer you the opportunity to delight millions of TV streamers around the world while gaining meaningful experience across a variety of disciplines. Roku is the No. 1 TV streaming platform in the US, Canada and Mexico, with more than 100 million active accounts. Every ad impression across that platform has to be cleared and priced in real time — that is what the Ads Auctions and Marketplace Optimization team does. We build the auction mechanics, the pricing and pacing logic, and the low-latency systems that run them, balancing outcomes for advertisers, publishers, viewers, and Roku on every request. We are growing the team in Cambridge, which is becoming its largest hub, alongside colleagues in Amsterdam, Austin, San Jose, Ukraine and Uruguay — so you would be shaping how the UK side of this team works rather than inheriting it. You will build the systems that apply mathematical and algorithmic rigour to optimise across multiple objectives, deciding which ads get served, in which placements, and when. The work spans auction mechanics, optimisation, the output of predictive ML models, and the real-time infrastructure underneath, mostly in Java on the JVM. It is hands‑on and senior in scope: expect to move between whiteboard‑level design and production code in the same week, and to own problems from framing through rollout. You will work directly with the hiring manager and a small group of senior engineers, in codebases shared with other ads engineers, on problems where your decisions are visible in revenue. You will optimise for second‑order effects in a marketplace where participants react to each other, and to us, in real time. We are looking for people who are enthusiastic about solving these kinds of problems. At Roku, we don't just use AI, we work with it. AI agents and smart tools help power drafts, analysis, and repetitive workflows, while our people bring direction, judgment, and accountability.

And you can describe projects where you shipped real work with these tools. You know how to drive an agent, verify its output, and ramp on an unfamiliar codebase with an agent helping you. • Design and build components of Roku's real‑time ad auction and marketplace systems, • Own the multi‑objective optimisation at the core of the auction, balancing what advertisers, publishers, viewers, and Roku each want from the same impression, • Own development work end to end, from framing the problem through production rollout, • Build and operate JVM services where latency and reliability are product requirements, not stretch goals, • Use probability, statistics and experimentation to test changes before and after launch, • Work with AI tooling as a normal part of how you design, build, test and review, • Explain technical trade‑offs clearly to engineering and cross‑functional partners, • Around six or more years building production software, with strong systems judgement, • Production experience in Java or another JVM language, or depth in a comparable statically typed language such as C#, C++ or Go, and the appetite to ramp on Java, • Comfort designing and operating distributed systems at scale and low latency, • A solid grounding in maths, algorithms, probability and statistics as applied to real systems, • Demonstrated AI and agentic‑tooling fluency, as described above, • Ad tech, auctions or marketplace experience is preferred, and we move quickly for candidates who have it, • Comparable experience on mathematically rigorous or optimisation‑heavy problems in another domain is an acceptable alternative Roku fosters an inclusive and collaborative environment where teams generally work in the office Monday through Thursday.
