What you'll do

• Are you a senior software development engineer who wants to own the architecture and technical direction of systems that hundreds of thousands of AWS customers rely on to keep their cloud environments Are you a senior software development engineer who wants to own the architecture and technical direction of systems that hundreds of thousands of AWS customers rely on to keep their cloud environments secure and compliant?
• The AWS Config Reaction team is looking for an SDE III to lead across our core compliance platform, including the rules evaluation engine, conformance packs, advanced query, aggregators, and automated remediation.
• AWS Config is how customers enforce security policies, detect misconfigurations, and maintain compliance with frameworks like PCI-DSS, HIPAA, and FedRAMP, both reactively and proactively, across entire AWS Organizations.
• Our platform continuously assesses millions of resources across thousands of accounts, aggregates compliance data at org scale, enables ad-hoc resource querying, and automates remediation, powering compliance at scale for enterprises worldwide.
• You'll own critical architecture end-to-end: defining the technical direction, leading the design of distributed systems in ambiguous problem spaces, and driving delivery across the team, all while operating at massive scale across every AWS Region.
• Key job responsibilities - Lead the design, implementation, and delivery of high-scale, highly available distributed services that power the AWS Config Compliance Reporting platforms - Own team-level architecture decisions, define system boundaries, interfaces, and scaling strategies in complex problem spaces with visible risks, roadblocks, and constraints - Decompose large efforts into parallel workstreams, enabling the team to deliver cohesively at speed - Drive technical direction across the team and influence adjacent teams (Resource Explorer, Security Hub, Weirwood, Control Tower) when projects cross boundaries - Improve platform scalability, reliability, and cost efficiency proactively, identifying problems before they become incidents - Mentor and raise the bar for L4 and L5 engineers through design reviews, code reviews, and technical guidance - Participate in on-call rotation, drive root cause analysis, and build lasting operational improvements - Represent the team's technical perspective in roadmap discussions and contribute to multi-quarter planning A day in the life As an SDE III on the Config Reaction team, you'll define architecture for distributed systems that evaluate compliance and aggregate data at massive scale.
• On any given day, you might be writing a design doc that decomposes a complex capability into parallel workstreams, leading a design review, resolving a scalability problem where constraints conflict, or aligning with engineers on adjacent teams.
• You'll work closely with a dedicated Principal Engineer and operate with high autonomy, owning technical direction end-to-end.
• About the team The Config Reaction team owns the services that run on top of Config Recording and Config Rules, a platform used by enterprise customers managing millions of resources across thousands of accounts and multiple regions.
• We build the systems that enable customers to continuously assess compliance, detect drift, and enforce security policy across their entire AWS environment.

Requirements

• Practical experience with React, AWS, Scala.
• Experience level: 5+ yrs.
