The Policy & Access Control Engineering (PACE) team, under Operations Infrastructure Services (OIS) organization is looking for an experienced System Development Engineer to join team in Austin. The PACE team provides network security solutions to Amazon fulfillment centers (FCs) using Access Control Lists (ACLs) deployed on on premise firewall as well as cloud firewall devices. ACLs act as a gatekeeper, allowing or blocking network traffic flow in and out of FCs based on predefined rules. Changes in the underlying infrastructure necessitate updates in deployed ACLs to ensure seamless operation of FC solutions. To maintain the right security posture while enabling FC solutions to get network connectivity within defined Service Level Agreements (SLA), the PACE team focuses on two aspects: 1) ACL Freshness: the frequency with which ACLs are deployed to network devices, 2) ACL effectiveness: determines if the ACLs defined by the FC solutions using OIS tools are used effectively and are not adding unnecessary complexity to the OIS network.

Key job responsibilities
In the PACE team, the System Development Engineer (SysDE) plays a crucial role in ensuring the smooth and secure operation of Amazon's FC solutions. The ideal candidate will:
- Identify business problems, gathers data, proposes solutions and leads implementation.
- Lead the development and maintenance of systems accountable for generating and deploying ACLs information to network devices. These systems must ensure high availability, scalability, and performance to meet stringent SLAs for ACL freshness and effectiveness.
- Partner closely with cross-functional teams to align on requirements, security guidelines, and best practices for ACL management and network security.
- Proactively identify and address technical debt, architectural limitations, and performance bottlenecks, proposing and implementing refactoring and optimization strategies to improve the systems' efficiency and maintainability.
- Ensure robust monitoring, alerting, and troubleshooting mechanisms are in place for the ACL management systems.
- Give careful consideration of availability, operations, maintenance, and cost.
- Exercise high judgement, skepticism, and scrutiny of requests to ensure that changes do not lead to unsupportable systems, non-compliance, security vulnerabilities or detrimental impact.
- Design the complete solution stack and delivers through others.
