Software Development Manager Jobs in Palo Alto, CA

Amazon Advertising is a multi-billion-dollar business and one of the fastest-growing at Amazon. The Autonomous Development team within Ads AI Core Infra (ACI) org is reinventing how advertising software gets built: we develop AI agents and developer-intelligence systems that write, review, and ship production code across the Ads org. If you want to work at the frontier of agentic software development — where large language models do the implementation and engineers design the systems that make them correct, safe, and scalable — this is the team.

We are looking for an experienced Software Development Engineer to build the platforms behind autonomous software delivery. Our systems already index tens of thousands of software pipelines to give engineers and AI agents grounded, up-to-date answers about how Amazon's code actually works; they generate code changes directly from feature specifications; and they take real engineering intake from partner teams and deliver working, reviewed code with minimal human involvement. You will design the services, data platforms, and evaluation infrastructure that let these agents operate reliably at Amazon scale.

This is high-ownership, high-impact work. The problems span distributed systems, large-scale data and retrieval, LLM orchestration, and the evaluation frameworks that let us trust autonomous output enough to ship it. You will build systems that thousands of builders depend on every week, and your work will directly move how fast the entire Ads org can turn an idea into shipped software.

Key job responsibilities

• Design, build, and operate large-scale distributed services that power AI agents and developer-intelligence systems used across the Ads organization
• Build retrieval and indexing platforms that keep AI agents grounded in how Amazon's code and systems actually work, refreshed continuously and at scale
• Develop agentic code-generation systems that turn specifications into reviewed, production-ready code changes
• Build the evaluation and quality infrastructure that measures agent correctness and gives engineers the confidence to ship autonomous output
• Drive technical design for ambiguous, greenfield problems and raise the engineering bar through design and code reviews
• Partner with applied scientists and other engineering teams to take AI capabilities from prototype to reliable, monitored production systems
• Own operational excellence — reliability, latency, cost, and observability for systems running 24/7

A day in the life

• Design and implement features for our agentic development and code-intelligence platforms
• Debug and optimize distributed systems and retrieval pipelines for correctness, latency, and cost
• Build and review evaluations that quantify how well our agents perform on real engineering work
• Collaborate with engineers and applied scientists across Ads to integrate and scale AI capabilities
• Participate in design discussions, code reviews, and architectural deep-dives
• Mentor other engineers and help raise the team's technical bar

About the team
We are the Autonomous Development team within the Ads AI Core Infra (ACI) organization at Amazon Advertising. Our mission is simple to state and hard to do: change how advertising software gets built, so that an idea can become shipped, production-quality code faster than ever before. We build the agents and developer-intelligence platforms that the rest of the Ads org relies on to move quickly and correctly.

We operate at the frontier of agentic software development, where large language models do the implementation and engineers design the systems that make that output correct, safe, and scalable. Our work is genuinely greenfield — there is no playbook for grounding LLMs in massive, constantly-changing codebases or for trusting autonomous code enough to ship it. We figure it out, build it, and put it in front of thousands of builders.

Culturally, we value deep ownership, strong engineering judgment, and learning fast over being right the first time. Engineers here own meaningful systems end to end, work directly with applied scientists and partner teams across the org, and have an outsized impact on how Amazon Advertising delivers software. We care about each other, default to candor, and keep the bar high while staying a team people genuinely enjoy being part of. If you're excited to build the systems that make autonomous software delivery real at Amazon scale, you'll fit right in.
