Software Development Engineer II - Change Review , Amazon Software Builder Experience – Change Auto Review Experience (CRUX)

Are you passionate about shaping the change review experience in the era of AI? The Change Review team within Amazon Software Builder Experience (ASBX) builds the tools and services that help Amazon engineering teams understand, review, and ship software changes safely and confidently.

AI-assisted development is changing how software is created. We are looking for a Software Development Engineer II to build the next generation of change-review tooling for this evolving environment. You will independently own substantial services, experiences, and integrations that make review workflows safer, clearer, and more efficient as engineers adopt new ways to build software.

In this role, you will work backwards from builders, define component designs where the customer problem or technical direction is known but the solution is not, and deliver reliable systems across their full lifecycle. You will exercise sound engineering judgment, make pragmatic trade-offs, influence technical decisions, and remain accountable for the quality and operation of what you build.

Key job responsibilities

• Independently own substantial features and components of developer-facing review tools, from customer discovery and scoping through design, implementation, validation, deployment, operations, and improvement.
• Work with builders, product managers, and partner teams to understand evolving software-development workflows and translate their needs into clear requirements and technical solutions.
• Design reliable services, interfaces, and experiences that help engineering teams review software changes, understand relevant signals, and take appropriate action.
• Build integrations with code-analysis, testing, source-control, and developer-workflow systems, accounting for downstream effects in related systems.
• Evaluate how emerging technologies, including AI-assisted development, change the needs and constraints of code-review systems, and recommend appropriate technical approaches.
• Make and explain trade-offs across customer experience, business priorities, delivery speed, operational work, security, scalability, and long-term architectural health.
• Remain accountable for the correctness, security, maintainability, performance, test coverage, and operational readiness of the software you deliver, regardless of the tools used to produce it.
• Own operational health, diagnose root causes, deliver durable corrections, reduce systemic support costs, and improve reliability, observability, and technical processes.
• Lead constructive technical and design reviews, align with partner teams, share knowledge, and mentor less-experienced engineers.

A day in the life Your morning might start with a design discussion, whiteboarding a new feature with your team before diving into hands-on coding. You will balance building new capabilities with improving existing systems, participating in code reviews, and sharing knowledge with teammates. You will regularly connect with product partners to ensure what you are building aligns with customer needs, and you will have the autonomy to propose and experiment with new approaches that make your team's software better.

About the team Our team is focused on building software that directly impacts the customer experience at Amazon. We value collaboration, technical craftsmanship, and a commitment to operational excellence. We invest in each other's growth through mentorship, knowledge sharing, and an inclusive environment where every voice is heard. As we look ahead, we are excited about opportunities to apply new technologies and simplify our systems to deliver even greater value for our customers.
