About The Position

We're looking for a Senior DevOps Engineer who thrives at the intersection of software engineering and infrastructure. You'll help keep some of the web's highest-traffic real estate platforms running at scale — and you'll have a real say in how we evolve our platform engineering practices. If you care deeply about automation, resilience, and developer experience, this is the job for you. This position is located in Arlington, VA and offers a schedule of Monday through Thursday in office and the option to work from home Friday.

Requirements

5+ years of DevOps or platform engineering experience, ideally supporting high-traffic, consumer-facing web products.
Fluent in infrastructure as code — Terraform and Helm are your default tools, not an afterthought.
Solid cloud experience on at least one major provider (AWS preferred; Azure and GCP familiarity a bonus).
Comfortable scripting in Bash and at least one higher-level language (Python, PowerShell, TypeScript, or similar).
Configured and tuned CDNs for performance caching and global traffic management.
Understand large-scale network fundamentals — DNS, hypervisors, containers, databases, multi-datacenter topologies.
Have worked with SQL and/or NoSQL databases in a production context.
Bachelor’s Degree required from an accredited, not for profit, in person university or college
A track record of commitment to prior employers

Nice To Haves

Experience with Kubernetes, container orchestration, or serverless architectures.
Background in software development (Java, C#, Python, Node.js) — you'll work closely with engineers, and speaking their language helps.
Familiarity with PCI compliance and remediation workflows.
Mobile platform support experience (iOS / Android infrastructure).
Experience designing or consuming REST APIs and microservices.
Agile/Scrum experience in short sprint cycles.

Responsibilities

Architect & automate infrastructure using IaC tools (Terraform, Helm) across AWS, Azure, and on-prem environments.
Own the CI/CD pipeline — design, build, and optimize delivery workflows using tools like Azure DevOps Pipelines, Jenkins, or ArgoCD.
Drive observability — instrument applications and infrastructure with APM, synthetic monitoring, RUM, and log aggregation (e.g., Datadog, New Relic, Splunk).
Scale for traffic — support mass-scale web architecture across multiple brands and products; performance is non-negotiable.
Strengthen the platform — manage CDN configuration, DNS, load balancing, containerized workloads (Docker/Kubernetes), and multi-region reliability.
Write real code — automate everything you can with Bash, Python, PowerShell, or TypeScript; leverage AI tooling to accelerate development and push back on toiling relentlessly.
Collaborate cross-functionally — partner with product engineering, security, and network teams to deliver safely and quickly.
Mentor & grow — support hiring, onboarding, and the professional growth of teammates; share what you know generously.
