The Traffic Applications team, part of Measurement, Ad Tech, and Data Science (MADS), owns the data ingress system for all of Amazon Ads. Traffic ingests hundreds of billions of ad events daily from upstream systems, decorates them with dimensional and identity data, and publishes structured traffic and billing datasets in a standardized format to downstream consumers across the Ads ecosystem. The system operates under strict SLAs for data freshness and accuracy on tier-one advertising metrics, owning three of the five critical metrics used for Ads billing. As the first MADS system to encounter regulatory and identity changes, Traffic's architectural decisions propagate across the entire MADS stack, making design choices here uniquely consequential.
You will have the opportunity to work on critical business initiatives that directly impact Ads VP and SVP level goals. These include compliance initiatives such as GDPR and ePrivacy, enabling geo-targeting features, and driving architecture scalability to support spiky traffic from live sports events.
Key job responsibilities
As a SDE , you will:
- Own team architecture and lead design on multi-engineer efforts across our Spark-based EMR pipelines, decoration jobs, and publication systems
- Navigate ambiguous technical problems with conflicting constraints - regulatory deadlines, performance requirements, cost targets, and cross-org dependencies
- Identify one-way-door decisions, proactively address architectural deficiencies, and ensure Traffic's design doesn't limit what downstream teams can build
- Drive adoption of engineering best practices and maintain sound operations - alarms, telemetry, runbooks - for a system with tier-1 SLAs
- Mentor engineers, contribute to recruiting, and lead constructive technical dialog within the team and across Ads, Customer Trust, and identity-owning upstream systems
What we're looking for?
- Expertise in large-scale distributed data processing (Spark, EMR, or equivalent)
- Demonstrated ownership of end-to-end system architecture on complex, cross-team projects
- Ability to influence technical decisions across organizational boundaries without direct authority
- Experience operating production systems under strict SLAs at massive scale
A day in the life
On a typical day as an Ads Traffic SDE, you might:
- Start your morning with a team stand-up to align on priorities and address any blockers
- Collaborate with product managers to refine requirements for upcoming features
- Write code and develop solutions for complex technical challenges
- Review pull requests from team members, providing constructive feedback
- Participate in design discussions for new services or features
- Debug and troubleshoot production issues as they arise
- Attend learning sessions to stay current with Ads technologies
- Document your work and contribute to technical specifications
- Engage with customers or internal stakeholders to better understand their needs
