Software Development Engineer

Who you are

• Experience programming with at least one modern language such as Java, C++, or C# including object-oriented design
• Experience in professional, non-internship software development
• Experience building complex software systems that have been successfully delivered to customers
• Bachelor's degree in computer science or equivalent
• Experience with full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations

What the job involves

• We're looking for an experienced Software Development Engineer to join our team focused on Third-Party Ad Serving (3PAS) within Amazon DSP
• This team owns the core infrastructure and experiences that enable advertisers to manage and deliver third-party display and video creatives at scale through Amazon DSP — supporting a wide variety of ad servers, creative formats, and compliance workflows
• Own end-to-end delivery of features across our creative validation services and 3PAS creative templates for display and video — from design through production rollout
• Triage and resolve customer-facing tickets on creative rejections, both at campaign launch and during continuous eligibility checks, partnering with product and account teams to unblock advertiser campaigns
• Implement and evolve creative validation rules across video, streaming audio, and display inventory — covering duration, resolution, bitrate, codec, channel, and loudness specs for premium streaming surfaces
• Build and maintain 3PAS creative templates for display and video, ensuring compatibility with industry standards (VAST, DAAST, MRAID, IAB) and major third-party ad servers
• Optimize service infrastructure for cost, throughput, and latency to keep up with Streaming TV creative volume growth, and improve observability so advertiser-driven failures are clearly distinguished from service-side regressions
• Deploy features safely through CI/CD, participate in on-call rotations for advertiser-impacting events, and monitor launches and experiments to measure and communicate impact on campaigns and ad spend
• A day in the life
• You’ll join a high-performance, agile team in a collaborative environment where your contributions have immediate, visible impact
• A typical day might include:
• Attending a daily standup to align with your team
• Triaging incoming customer tickets to unblock advertiser campaigns
• Preparing solution designs for new validation rules, template features, or infra improvements, and collaboratively reviewing them with your team
• Researching challenging problems independently or teaming up
• Partnering with product and customer teams to translate new inventory specs (new formats, marketplaces, surfaces) into validation logic and creative template support
• Deploying your changes to production through CI/CD, keeping stakeholders up to date and monitoring impact on advertiser campaigns and ad spend
• Seeing your work go live across Amazon's premium Ads inventory, powering ad experiences for customers across the globe
• We are the 3PAS team, owning third-party ad serving within Amazon DSP
• Our systems power the delivery, validation, and management of externally hosted display and video creatives at scale, with real-time compliance checks, policy enforcement, and downstream moderation
• We're also building agentic AI observability across the 3PAS creative lifecycle, enabling proactive detection and remediation of issues before they impact advertisers
• From UI extensibility to backend integrations, we build the infrastructure that supports a growing ecosystem of third-party ad servers and creative partners — empowering advertisers to innovate without compromising customer trust or operational excellence
