Sr. Software Development Engineer, AWS Security

Job description

At Amazon, Security is our highest priority. Are you interested in shaping the future of security for AWS, our customers, and the broader open source community? Do you want to be part of building something with massive impact? Our AWS Security Customer Outcomes Team is looking for strong software engineers as we help improve the security of open source software and the safety of the software supply chain generally.

Today is just the beginning, and we want you to be part of our journey to innovate the way in which our users experience security. Our systems operate on a global scale across a diverse ecosystem of field teams, security requirements, and tooling.

We are seeking a Senior Software Engineer to define, design, build, and operate AI-powered security solutions across the full pipeline of open source software usage. You will build intelligent automation that augments manual identification, analysis, and remediation workflows, enforces security guardrails for agents and human experts, and provides data-driven insights to AWS leadership. This is a high-autonomy role requiring the ability to work with both internal and external stakeholders to elicit key needs and independently develop solutions from whiteboard to production while mentoring and upskilling security engineers on the team.

Key job responsibilities

Key Responsibilities

Architect and build AI-powered security applications and tooling — Design and implement LLM-based systems (leveraging Bedrock, SageMaker, and RAG patterns) for intelligent code scanning, severity assessments, and remediation alternatives.

Transform manual processes – Reimagine and deliver change from low throughput, human-dependent processes into high volume, machine speed pipelines without sacrificing key quality metrics.

Collaborate with and influence other leaders – The open source ecosystem has many stakeholders, and change requires listening and supporting but also influencing and leading through action.

Drive proactive security automation — Build systems that identify and remediate security issues in deliverables (code, threat models, content) without requiring explicit builder consent at every step, moving from reactive reviews to proactive prevention

Own operational excellence — Define and maintain SLAs, monitoring, alerting, runbooks, and incident response for services you own; participate in on-call rotation to support 24/7 availability

Lead technical design — Produce design documents, conduct trade-off analysis, and drive alignment across organizations.

Raise the engineering bar — Mentor security engineers, conduct code and design reviews, and contribute to team standards; proactively upskill existing SecEngs toward SDE capabilities where appropriate
