Senior SDE - AWS Fault Injection & Chaos Engineering

Amazon Inc.; Dublin; On-site; EUR 120,000 - 160,000; Full time

Job summary

Amazon AWS Fault Injection Service (FIS) is a fully managed platform designed to run fault injection and chaos engineering experiments on AWS. We seek a Senior Software Development Engineer to own fault actions’ design and delivery, enabling controlled disruption of production‑grade AWS services with safety controls and blast-radius protections.

The role emphasizes architecture, writing scalable, reliable code, and mentoring engineers, while collaborating with AWS service teams to deliver

Qualifications

• Experience as a mentor, tech lead or leading an engineering team.
• Experience leading the architecture and design (architecture, design patterns, reliability and scaling) of new and current systems.
• Experience in professional, non‑ internship software development.
• Experience programming with at least one modern language such as Java, C++, or C# including object‑oriented design.
• Experience in development in the last 3 years.

Responsibilities

• Own the architecture for one or more FIS fault domains, providing a system‑wide view and design guidance, and act as a key influencer on your team's technical strategy and goals.
• Design, build, and release software at large scale for AWS customers worldwide, then operate it in production and keep it highly available and durable.
• Build new fault actions and target types end to end: API design, authorization, execution logic, automated testing, and documentation, and safely evolve existing ones.
• Identify high‑impact, hard‑to‑reverse technical decisions early, and drive the team toward durable solutions rather than short‑term workarounds, especially where customer safety and blast radius are at stake.
• Raise the operational bar for your team: strong alarms and telemetry, clear runbooks, effective guardrails, and a healthy culture of incident review and continuous improvement.
• Partner with the AWS service teams whose faults FIS supports to design integrations and land cross‑team deliveries successfully.
• Advise your management and senior leadership on technical trade‑offs, and contribute to short‑and‑long‑term planning.
• Actively mentor multiple engineers and champion engineering best practices that others adopt.
