Amazon Advertising organization is democratizing advanced advertising capabilities, giving millions of sellers and brands access to sophisticated optimisation tools that were previously only available through agencies or expensive third-party providers. We are building the next generation of agentic AI systems that will transform how millions of advertisers interact with Amazon's advertising platform. By combining innovative large language models, autonomous agents, and Amazon's unmatched first-party data on shopper behaviour and conversion patterns, we're creating intelligent systems that reason, plan, and act on behalf of advertisers – delivering insights and optimisations that vastly outperform manual campaign management.

We are looking for a Senior Software Engineer who will lead the technical vision and innovation in revolutionising how advertisers succeed on Amazon. You will be part of a newly formed team building a horizontal agentic AI layer – the next generation of AI-powered marketing experts that transform how advertisers of all sizes create, manage, and optimise their campaigns.

As a Senior Software Engineer, you are a recognised technical leader who drives the engineering strategy, mentors team members, and partners with cross-functional teams to deliver complex end-to-end AI solutions. Your work focuses on architecting and implementing robust systems in ambiguous problem areas where both the business problem and solution approach need to be defined. The problems you tackle require significant technical innovation at the product level – from guiding less experienced sellers through campaign setup to automatically surfacing optimisation opportunities that unlock advertiser success.

You take ownership of the long-term technical vision, product roadmaps, and technologies, defining how they should evolve. You build consensus through thoughtful discussions with stakeholders, scientists, and engineering peers across multiple teams. You bring deep expertise to provide context for current and future technology choices, and make strategic recommendations on system architecture and implementation approaches to achieve transformative business outcomes – ultimately strengthening Amazon's advertising ecosystem and helping more advertisers thrive.
