Job summary

Amazon is seeking an SDE II to own major features across two connected products: AWS Specialist Agent and Specialist Knowledge Vault. You will design, build, and operate significant platform components, focusing on retrieval-augmented generation, multi-agent orchestration, and LLM evaluation at scale.

The role emphasizes raising engineering standards and collaborating with product management and field teams.

Qualifications

• 3+ years of non-internship professional software development experience.
• 2+ years of design or architecture experience for large systems.

• Design APIs and MCP/A2A integrations as clean, reusable interfaces that bring ASA and KV into the tools where field teams already work.
• Drive operational excellence for the services you own: define monitoring and alarming, lead incident response during on-call, fix root causes, and run COE and metrics reviews.
• Work with Product Management, Applied Science, and TFC stakeholders to turn ambiguous field problems into well-scoped projects.
• Raise the team's bar through thorough code reviews and design reviews. Mentor and onboard SDE IIs and new team members, and take part in recruiting and interviewing.
