We’re looking for a Senior Dev Ops 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. 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.

• 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 Dev Ops 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, Power Shell, or Type Script; 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.

• 5+ years of Dev Ops 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, Power Shell, Type Script, 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 No
  
  SQL 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.

• 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.

When you join CoStar Group, you’ll experience a collaborative and innovative culture working alongside the best and brightest to empower our people and customers to succeed. We offer…
