Software Development Engineer, Security Software Development Operations; SSDO

Software Development Engineer II

Amazon's Security Software Development Operations (SSDO) team is seeking an experienced Software Development Engineer II to drive architectural decisions and complex system design for security automation platforms. In this role, you will own software features end-to-end, design cohesive implementations for security tools, and mentor fellow engineers while delivering solutions that protect Amazon's global infrastructure. You will work at the intersection of AI/ML, cloud security, and data sovereignty—building platforms that enable security teams to operate at scale across opt-in regions and sovereign cloud environments.

As an SDE II on this team, you will influence technical direction within the team, balance customer requirements with operational needs, and demonstrate operational excellence across all work. You will design solutions for difficult problems where answers are not immediately obvious, bringing clarity and identifying simple, elegant designs.

Key job responsibilities:

• Own software features for security automation platforms, AI-enabled chatbot and data enrichment tooling, driving them from design through deployment and maintenance.
• Design and architect complex system components including RAG-based AI implementations, clean room architectures, and cross-platform intelligence integrations with limited guidance, making design tradeoffs that balance security, performance, and maintainability.
• Provide constructive code review direction to peers including senior engineers, ensuring code quality, security best practices, and adherence to Dev Sec Ops  principles across all team deliverables.
• Actively mentor junior engineers and train new teammates on team software, security architecture patterns, and development processes.
• Collaborate with Security Engineers who define security requirements and threat modeling, translating those requirements into scalable technical implementations.
• Drive improvements to the team's development and testing processes, operational runbooks, and software quality standards.
• Engage with Director-level stakeholders to communicate technical decisions, project status, and business value of security automation initiatives.

A day in the life:

Your morning might begin with a design review for a new sovereignty monitoring feature, where you evaluate approaches for implementing continuous compliance checks across opt-in regions using AWS Control Tower and Resource Control Policies. Mid-morning, you conduct code reviews for a junior teammate's implementation of a document sanitization pipeline, providing constructive feedback on error handling patterns and suggesting architectural improvements. After lunch, you lead a technical discussion with Security Engineers about exception handling patterns for AI/ML workloads within one of Amazon's Dedicated Clouds.

You spend the afternoon designing the next phase of the GEIR chatbot's RAG architecture, making tradeoffs between retrieval accuracy and latency while ensuring compliance with security control standards. Before end of day, you update your design document and prepare a brief for your manager on the projected impact of the automated audit production system.

About the team:

The SSDO embedded development team is a small, high-impact group within Amazon's security organization. We build the tools and platforms that security professionals rely on daily—from AI-powered service teams facing consultants that reduce analyst workload by 60–70%, to automated monitoring systems that maintain separation between sensitive investigation teams. Our work spans five distinct teams and directly supports security operations across multiple business units.

We operate in a matrix structure where security domain experts define the "what" and "why," and our engineering team owns the "how". We value operational excellence, customer obsession, and the ability to deliver simple solutions to complex security challenges.

Diverse Experiences:
