Sr. Staff Software Engineer, Advertiser and Seller Experience

What you’ll do

• Own end-to-end technical delivery for cross-team initiatives, from problem framing and technical strategy through architecture, implementation, rollout, and iteration.
• Shape advertiser and seller platforms for scale, reliability, and quality, ensuring experiences are intuitive, intelligent, and trusted across ad buying, reporting, and seller workflows.
• Build and evolve ML, GenAI and AI-assisted advertiser and seller experiences with strong validation and guardrails. For example, intelligent recommendations, automated insights, and tools that improve platform usability without compromising trust.
• Contribute to advertiser and seller platform initiatives that span teams, creating streamlined flows and decisioning pathways that improve time to value, campaign performance, and seller efficiency.
• Partner where appropriate on performance measurement, advertiser insights, and data-driven pathways that connect platform engagement to business outcomes, ensuring strategy is measurable rather than anecdotal.
• Drive technical decisions using clear tradeoffs across revenue, conversion, advertiser and seller experience quality, and engagement.
• Mentor senior engineers and raise the bar for technical design, engineering quality, and production readiness across the organization.
• Use AI to accelerate your own work across exploration, drafting, analysis, and synthesis, while maintaining strong judgment, rigorous validation, and accountability for outcomes.

What we’re looking for

• 10+ years of software engineering experience building and operating complex production systems.
• Strong track record in ads, advertiser tooling, seller platforms, or other adjacent large-scale domains, including leadership on cross-team technical initiatives.
• Deep experience in systems design, API design, and data-intensive systems, with the ability to navigate tradeoffs in performance, reliability, and scalability.
• Experience building or partnering on ML, AI, or GenAI-adjacent systems, with a pragmatic understanding of where these technologies add value and how to deploy them responsibly.
• Advertiser platform, seller experience, or ads integrations experience is a strong plus.
• Experience with growth, measurement, funnel optimization, or ads performance ecosystems is a plus.
• Strong communication skills and the ability to influence technical direction without directly owning every implementation detail.
• Bachelor's degree in Computer Science, Engineering, or a related technical field or equivalent practical experience.
