AI in this role
Our team is developing an agent platform that coordinates multiple specialized AI sub-agents to execute complex, multi-step advertising workflows. You'll own the architectural direction for these systems, partner with Applied Scientists on learning systems, drive technical strategy with product teams on advertiser experience, and build the identity and authorization frameworks that keep it all secure. This is a small, high-ownership team where you'll shape how AI transforms advertising from the ground floor — influencing technical direction beyond your own team and establishing the engineering practices that scale as the platform grows.
Key job responsibilities
- Own the architectural direction for orchestration systems that coordinate multiple specialized AI sub-agents to execute complex, multi-step advertising workflows
- Design and build identity, authorization, and permission frameworks that enforce scoped access for diverse caller types — making foundational technical decisions that shape the platform long-term
- Design feedback signal pipelines that capture expert judgment and route it into model improvement loops
- Partner with Applied Scientists to integrate reinforcement learning from human expert feedback into production agent systems, driving the technical strategy for how learning systems evolve
- Design and operate end-to-end evaluation systems that measure recommendation quality, detect regressions, and enforce quality gates
- Establish and drive technical partnerships with cross-functional teams (product, science, partner engineering) to define integration contracts and onboard new consumers to the platform, influencing their technical direction
- Own system reliability, observability, and performance for always-on agent infrastructure serving thousands of concurrent advertiser accounts
- Mentor engineers, lead design reviews, and drive adoption of engineering best practices across the team
A day in the life
You might start the morning reviewing eval results from a newly onboarded agent skill, diagnosing why routing accuracy dropped 2%. By mid-morning, you're pairing with an Applied Scientist to tune the feedback pipeline that captures expert signals. After lunch, you're designing the permission model for a new integration. You end the day shipping an observability improvement that surfaces latency bottlenecks across the orchestration chain. Every day is different, but the thread is the same: making AI agents smarter, safer, and more reliable at scale.
About the team
We're a small, high-ownership team within Amazon Ads building the platform that makes AI agents accessible across the advertising ecosystem. Our charter is greenfield: we're defining how agent intelligence gets exposed to other engineering teams. We work closely with Applied Scientists on learning systems, product teams on advertiser experience, and platform teams on shared infrastructure. The team values builders who ship fast, think in systems, and are comfortable operating in ambiguity. If you want to shape how AI transforms advertising from the ground floor, this is the team.
Basic qualifications
- 5+ years of non-internship professional software development experience
- 5+ years of programming with at least one software programming language experience
- 5+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience
- Experience as a mentor, tech lead or leading an engineering team
Preferred qualifications
- 5+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
- Bachelor's degree in computer science or equivalent

Questions you could be asked
- How do you decide when an AI agent can act on its own versus asking for approval first?
- How would you decide a model or AI system is ready to ship?
- Tell me about a time a model underperformed in production. How did you find out, and what did you change?
Adapt your resume
- List these exact terms on your resume: AI agents. An applicant tracking system matches the wording, not the idea.
- Attach one line of real, concrete experience to at least one of them. A tool named with nothing behind it rarely survives a human read.
- Lead with what you built, trained or shipped. This role is judged on the AI system itself, not the tools around it.
