Senior Cloud Engineer (Hybrid @ Bellevue, WA or Remote @ Florida)

<p> <strong>Headquarters:</strong> Bellevue, WA or Remote Florida </p> <p><strong>Team Charter:</strong></p> <p>The Cloud Engineering team is dedicated to maintaining and evolving cloud infrastructure, CI/CD pipelines, Application Security, Change Management, and Backend application golden templates. We are the backbone of the technical organization, ensuring the foundation of our services is robust, secure, and efficient.</p> <p><strong>About the role:</strong></p> <p>We are looking for a <strong>Senior Cloud Engineer</strong> to join our <strong>Cloud Engineering</strong> team. This team is tasked with <strong>ensuring scalability, reliability, and security for all backend services</strong> and keeping the SDLC running smoothly for engineers across the company.</p> <p>As a senior member of the team, you will own meaningful pieces of our cloud platform end-to-end — from design through deployment and operation — while helping shape the standards, tooling, and golden templates that the rest of the engineering organization builds on. You will balance deep, hands-on technical ownership with mentoring teammates and influencing the technical direction of the systems that power a large-scale mobile marketplace.</p> <p><strong>What we love about this role:</strong></p> <ul> <li>Scale & Impact: You will work on systems that drive the end-user experience and support every technical team across the organization, operating across a multi-account AWS and GCP footprint.</li> <li>Ownership: You will own critical infrastructure and platform capabilities end-to-end, making architectural decisions that affect reliability, security, and cost at scale.</li> <li>Force Multiplier: The templates, pipelines, and tooling you build raise the productivity and safety of every engineer at OfferUp.</li> <li>Emerging Technology: You will help bring new capabilities — including AI/ML developer tooling and infrastructure — into the hands of our engineers.</li> </ul> <p><strong>In this role, you will</strong> design, build, and operate the cloud infrastructure, platform tooling, and CI/CD systems that underpin OfferUp's core applications. Day to day, that means you will:</p> <ul> <li><strong>Build cloud infrastructure as code</strong> — design, implement, and maintain AWS and GCP infrastructure with Terraform, optimizing for reliability, security, and cost.</li> <li><strong>Own our Kubernetes & GitOps platform</strong> — run and evolve EKS/GKE (cluster upgrades, Envoy/Gloo networking, Helm, ArgoCD delivery).</li> <li><strong>Keep the SDLC fast and safe</strong> — build CI/CD pipelines and developer workflows (GitHub Actions, monorepo tooling, JFrog Artifactory), and maintain the backend “golden templates” and shared libraries the wider org builds on.</li> <li><strong>Lead platform migrations end-to-end</strong> — plan, execute, and de-risk observability, data-store, Kubernetes, and multi-account migrations, including rollback strategy.</li> <li><strong>Drive operational excellence & security</strong> — own observability in Datadog and on-call, remediate CVEs, manage secrets and access controls (Cloudflare/ZTNA, Okta, SSO, Workload Identity Federation), and optimize cloud cost.</li> <li><strong>Multiply the team</strong> — enable AI/ML developer tooling (Amazon Bedrock, Claude, AI-assisted workflows), lead design and code reviews, set technical standards, mentor engineers, and partner with other teams.</li> </ul> <p><strong>You'll thrive in this role if you have:</strong></p> <ul> <li><strong>Experience & Education:</strong> 5–8 years in cloud engineering, infrastructure, platform, DevOps, or SRE roles; Bachelor's in Computer Science or a related field, or equivalent practical experience.</li> <li><strong>Cloud & Infrastructure as Code:</strong> Deep, hands-on AWS (ideally GCP) — EKS/GKE, Lambda, networking, IAM, S3, Kinesis, OpenSearch, Route53 — managed declaratively with Terraform at scale.</li> <li><strong>Containers & Delivery:</strong> Solid experience with Kubernetes (EKS/GKE), Helm, GitOps (ArgoCD), and CI/CD pipelines (GitHub Actions or similar) in a monorepo or multi-service environment.</li> <li><strong>Observability & Operations:</strong> Modern observability tooling (Datadog or similar) for metrics, logs, traces, and alerting; supporting production systems, on-call, and debugging complex distributed systems.</li> <li><strong>Coding:</strong> Proficiency in at least one of Java, TypeScript, Python, or Go for automation, tooling, and platform development; comfort with scripting and SQL.</li> <li><strong>Communication & Leadership:</strong> Able to communicate technical concepts to technical and non-technical audiences, lead through influence, and mentor other engineers.</li> </ul> <p><strong>Helpful, but not required:</strong></p> <ul> <li>Experience with edge and zero-trust networking (Cloudflare, Envoy/Gloo).</li> <li>Experience operating data and streaming infrastructure (Kinesis, Flink, Redis/Valkey, Confluent/Kafka).</li> <li>Experience enabling AI/ML infrastructure or developer tooling (Amazon Bedrock, SageMaker, or LLM-based developer workflows).</li> <li>Experience with security and compliance practices, change management, and incident management at scale.</li> <li>Experience with
