Senior Platform Engineer, Growth Product Engineering

Stack

Responsibilities

• ▹Own the CI/CD foundation for AI-assisted and agentic development: hardened pipeline gates, high test coverage, mutation and end-to-end tests, blocking security scans, performance and cost regression guards, and progressive delivery with automated rollback
• ▹Give engineers a fast, safe inner loop with ephemeral per-PR environments and local tooling, including isolated databases seeded from realistic data
• ▹Build centralized logging, monitoring and alerting across the AWS footprint so every team has visibility and bad deployments roll back automatically
• ▹Lead security engineering: remediate vulnerabilities, establish secure-by-default patterns, and automate code scanning, secrets management and access control
• ▹Migrate hand-built AWS resources to Infrastructure as Code, separate production and pre-production accounts, and stand up tested backup and disaster recovery with clear RTO and RPO targets
• ▹Build paved-path, self-service tooling and standardized blue/green, canary and feature-flag releases while mentoring engineers
• ▹Build and operate AI agents for SRE work: automated alert triage, incident investigation and safe self-healing remediation
• ▹Contribute to backend development for products, shipping customer-facing features alongside the platform

Requirements

• ▹6+ years of professional software, infrastructure, DevOps, platform or site reliability engineering experience
• ▹Hands-on AWS production experience (IAM, Lambda, networking, multi-account organizations) with Infrastructure as Code such as Terraform, AWS CDK or CloudFormation
• ▹Designed and operated CI/CD pipelines (GitHub Actions, Buildkite) with automated testing, static analysis, coverage enforcement and deployment gates, plus safe release patterns such as blue/green, canary, feature flags and reliable rollbacks
• ▹Strong Python development experience across services, tooling and automation, working familiarity with JavaScript-based stacks, and experience with containerization and orchestration (Docker with ECS, EKS or Kubernetes)
• ▹Cloud security posture management (CSPM) or tools like Wiz, semgrep, snyk
• ▹Experience building observability into distributed systems: centralized logging, metrics, tracing and alerting (e.g. Sentry, Datadog, CloudWatch or Grafana)
• ▹Track record of designing, building and operating production infrastructure end to end with measurable gains in reliability, security or developer velocity, using AI-powered development tools (e.g. Claude, Cursor, Codex, Copilot) daily
• ▹Experience with product and feature development: building and shipping customer-facing features, not just internal platform work

Nice to have

• ▹Experience building guardrails that make AI or agent-generated code safe to merge and deploy: mutation testing, coverage enforcement, ephemeral preview environments or automated rollback
• ▹A developer experience or platform engineering background, with paved-path tooling that other engineers adopt
• ▹Familiarity with cloud cost management, performance regression detection, capacity planning and disaster recovery plans rehearsed against measured RTO and RPO targets
• ▹Exposure to localization pipelines and to GTM or data tooling such as Salesforce, Contentful, Hightouch or Databricks, plus an experiment-driven approach to adopting emerging AI technologies
• ▹Experience with SLIs and SLOs as the foundation for observability
• ▹Own the operational review process and look for ways to improve it
