Perform detailed data analysis to identify systemic patterns, diagnose platform drop-offs, and optimise client yield.
Partner actively with the local Commercial and Sales teams on strategic pitches, live platform demonstrations, and technical conversations to secure new regional business.
Function as the vital link between the market and our technical core, translating complex client requirements and product friction into clear, actionable feedback for global Product and Engineering teams.
Master the intricacies of video ad serving and programmatic operations, maintaining a deep understanding of evolving CTV, OTT, and premium video workflows

6+ years of experience in solution engineering, technical troubleshooting, or technical account management roles.
Service-oriented individual who is motivated by helping clients and teammates succeed
Strong technical troubleshooting skills to diagnose issues in complex, technical systems
Exceptional problem-solving skills - enjoys tackling ambiguous problems and finding creative solutions
Data-driven decision maker, experienced in analysing performance metrics and using data to improve efficiency and yield.
Client-facing experience and the ability to translate technical detail into actionable insights for partners and internal stakeholders.
The following experience would be a plus, but is not required:
Desire to collaborate closely with a tight knit, all-star customer success team
Familiarity with data querying and scripting languages (such as SQL, Python, and Pandas) and utilizing AI productivity tools (e.g., Claude Code)
Experience with video advertising, CTV, publishers, and the ad tech ecosystem
Experience providing technical support for clients of a SaaS platform
