Full Job Description

📋 Description

• Own the reliability, scalability, and performance of PDL’s multi-tenant data platform, which ingests and serves billions of people and company records daily to thousands of customers worldwide.
• Architect and continuously refine our AWS-centric infrastructure—spanning EC2, EKS, RDS, S3, Lambda, and EMR—while also extending our on-prem data-center footprint to balance cost, latency, and compliance requirements.
• Design, implement, and harden a fully automated CI/CD pipeline (GitHub Actions, ArgoCD, Terraform, Helm) that enables every engineering squad to ship code to production multiple times per day with zero-downtime deployments and instant rollback capabilities.
• Establish and monitor SLIs/SLOs that directly tie system health to customer experience; build error budgets, chaos-engineering experiments, and blameless post-mortems that turn outages into durable learning loops.
• Optimize petabyte-scale Spark and Flink pipelines for throughput, memory efficiency, and cost; tune JVM flags, shuffle partitions, and checkpoint strategies to cut runtime by double-digit percentages without sacrificing data fidelity.
• Instrument end-to-end observability using Prometheus, Grafana, Loki, and distributed tracing (OpenTelemetry) so anomalies are detected and triaged before customers feel them.
• Partner with Security & Compliance to embed guardrails into every layer—IAM policies, network segmentation, secrets management, and SOC 2 evidence collection—ensuring we stay ahead of evolving privacy regulations.
• Champion Infrastructure-as-Code best practices; every pull request to our Terraform or CloudFormation repos triggers automated policy checks (OPA, Checkov) and cost estimates so engineers see the blast radius of their changes in real time.
• Act as the on-call commander for critical incidents, orchestrating cross-functional war rooms, writing concise status updates, and driving long-term fixes that eliminate entire classes of failure.
• Mentor junior SREs and backend engineers through pair programming, design reviews, and weekly "lunch-and-learn" sessions that raise the technical bar across the organization.
• Experiment fearlessly with emerging technologies—Graviton instances, serverless Spark on Kubernetes, or data-tier caching with Redis 7—to shave milliseconds off API latency and dollars off the AWS bill.
• Contribute to open-source projects that we rely on, giving back to the community while showcasing PDL’s engineering culture at conferences and meetups.
• Translate complex technical trade-offs into clear narratives for product managers and executives, ensuring infrastructure investments are aligned with revenue-generating features.
• Build self-service tooling that empowers data scientists and ML engineers to spin up isolated, reproducible environments for model training without ever opening a support ticket.

🎯 Requirements

• 5+ years of production-grade experience designing and operating AWS infrastructure at scale (multi-region, multi-account) with deep expertise in EKS, RDS, S3, IAM, and CloudWatch.
• Expert-level proficiency in Infrastructure-as-Code (Terraform or CloudFormation) and container orchestration (Kubernetes, Helm, ArgoCD) in a data-heavy environment.
• Demonstrated success defining and meeting strict SLIs/SLOs for latency, availability, and durability in a SaaS or DaaS product serving external customers.
• Strong coding skills in Python or Go for automation, plus hands-on experience with CI/CD tooling such as GitHub Actions, Jenkins, or GitLab CI.
• Nice-to-have: hands-on tuning of Spark/Flink clusters, familiarity with SOC 2 or GDPR compliance workflows, and contributions to open-source observability projects.

🏖️ Benefits

• Fully remote-first culture with quarterly off-sites in exciting global locations and a generous home-office stipend.
• Competitive salary plus equity in a fast-growing, profitable data company backed by Tier-1 investors.
• Flexible PTO policy, 12 company holidays, and a mandatory "recharge week" each year when the entire company powers down.
• Annual learning & development budget ($3,000) plus paid attendance at conferences, certifications, and online courses.
