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

About the Role

OfferUp is seeking a Senior Cloud Engineer to join its dynamic Cloud Engineering team. This critical team is responsible for ensuring the scalability, reliability, and security of all backend services, while also maintaining a smooth Software Development Life Cycle (SDLC) for engineers across the company. As a senior member, you will take end-to-end ownership of significant components of the cloud platform, influencing standards, tooling, and foundational templates used by the wider engineering organization. This role balances hands-on technical expertise with mentoring and strategic technical direction for a large-scale mobile marketplace.

Why This Role is Exciting:

• Scale & Impact: Work on systems that directly influence user experience and support every technical team, operating across a multi-account AWS and GCP environment.
• Ownership: Take full responsibility for critical infrastructure and platform capabilities, making architectural decisions that impact reliability, security, and cost at scale.
• Force Multiplier: Develop templates, pipelines, and tooling that enhance the productivity and safety of all engineers at OfferUp.
• Emerging Technology: Contribute to bringing new capabilities, including AI/ML developer tooling and infrastructure, to the engineering team.

Responsibilities

In this role, you will design, build, and operate the cloud infrastructure, platform tooling, and CI/CD systems that underpin OfferUp’s core applications. Your day-to-day responsibilities will include:

• Building Cloud Infrastructure as Code: Design, implement, and maintain AWS and GCP infrastructure using Terraform, focusing on reliability, security, and cost optimization.
• Owning the Kubernetes & GitOps Platform: Manage and evolve EKS/GKE, including cluster upgrades, Envoy/Gloo networking, Helm, and ArgoCD delivery.
• Ensuring SDLC Speed and Safety: Develop CI/CD pipelines and developer workflows (GitHub Actions, monorepo tooling, JFrog Artifactory), and maintain backend “golden templates” and shared libraries.
• Leading Platform Migrations: Plan, execute, and de-risk migrations for observability, data stores, Kubernetes, and multi-account setups, including rollback strategies.
• Driving Operational Excellence & Security: Own observability in Datadog, manage on-call rotations, remediate CVEs, handle secrets and access controls (Cloudflare/ZTNA, Okta, SSO, Workload Identity Federation), and optimize cloud costs.
• Multiplying Team Capabilities: Enable AI/ML developer tooling (e.g., Amazon Bedrock, Claude, AI-assisted workflows), lead design and code reviews, set technical standards, mentor engineers, and collaborate with other teams.

Requirements

To thrive in this role, you should have:

• Experience & Education: 5–8 years in cloud engineering, infrastructure, platform, DevOps, or SRE roles. A Bachelor’s degree in Computer Science or a related field, or equivalent practical experience.
• Cloud & Infrastructure as Code: Deep, hands-on experience with AWS (ideally GCP), including EKS/GKE, Lambda, networking, IAM, S3, Kinesis, OpenSearch, Route53, managed declaratively with Terraform at scale.
• Containers & Delivery: Solid experience with Kubernetes (EKS/GKE), Helm, GitOps (ArgoCD), and CI/CD pipelines (GitHub Actions or similar) in a monorepo or multi-service environment.
• Observability & Operations: Proficiency with modern observability tooling (Datadog or similar) for metrics, logs, traces, and alerting; experience supporting production systems, on-call rotations, and debugging complex distributed systems.
• Coding: Proficiency in at least one of Java, TypeScript, Python, or Go for automation, tooling, and platform development; comfortable with scripting and SQL.
• Communication & Leadership: Ability to articulate technical concepts to diverse audiences, lead through influence, and mentor other engineers.

Helpful Experience (Not Required):

• Experience with edge and zero-trust networking (Cloudflare, Envoy/Gloo).
• Experience operating data and streaming infrastructure (Kinesis, Flink, Redis/Valkey, Confluent/Kafka).
• Experience enabling AI/ML infrastructure or developer tooling (Amazon Bedrock, SageMaker, or LLM-based developer workflows).
• Experience with security and compliance practices, change management, and incident management at scale.
• Experience with GCP Workload Identity Federation and cross-cloud (AWS↔GCP) integrations.
