Key job responsibilities

Amazon has a collaborative, purposeful and enthusiastic environment where we “Work Hard, Have Fun, Make History.” On a typical day engineers might dive deep into understanding the root cause of a customer issue, investigate why a metric is trending the wrong way and consult with the top engineers at Amazon. We own our services and believe in making out-of-hours support as painless as possible. To achieve this, we implement Operational Excellence best practices and strive to automate manual processes.

Our Senior Systems Engineers are considered technical leaders for their team and become subject matter experts in multiple services. They work efficiently and routinely deliver the right things with limited guidance. They use technology to solve complex problems. They are able to improve and/or drive improvements to these services and features for their team. They understand how their work impacts multiple teams. They are able to take a project, when the problem is not defined and deliver on schedule, applying appropriate technologies and industry systems-engineering best practices. They make effective implementation trade-off decisions and are able to assist others with trade-off decisions.

Our Senior Systems Engineers identify when implementations are not highly available, performant, secure, stable, maintainable, or have defects; and are able to determine short- and long-term mitigations. They have a depth and breadth of understanding in multiple areas of technology and they are excellent diagnosticians. They utilise their Linux expertise to troubleshoot, innovate fixes and workarounds, keep software up-to-date and provide data and metrics that help manage the capacity and efficiency of services.

Our Senior Systems Engineers are able to lead team design, scoping, and prioritization discussions. They understand how technical decisions impact their team, and other, teams’ services and recommend opportunities and solutions for these problems. They optimize and/or automate team processes, ensuring they meet organisation goals. They lead implementation reviews (e.g., designs, code, operational readiness, deployment plans, system changes, etc.). They anticipate and mitigate patterns that affect the performance, reliability, or availability of their team(s) systems to create automation that simplifies workloads that scale operations.

Our Senior Systems Engineers drive SOP, documentation, and runbook creation, reviewing them for accuracy; they drive the use of best practices. They actively recruit and interview for their team and help others leverage their own expertise, by coaching and mentoring. They communicate clearly and collaborate with others to deliver results. They are self-starters, comfortable dealing with ambiguity and change. They are customer-obsessed, always looking to understand customer pain points and find resolutions quickly and completely.
