Sr Software Development Engineer

Title: Sr Software Development Engineer Location: Renton, Washington, United States

At Wizards of the Coast, we connect people around the world through play and imagination. From our genre-defining games like Magic: The Gathering® and Dungeons & Dragons® to our growing multiverse, we continue to innovate and build new ways to develop friendship and connection. That's where you come in!

Magic: The Gathering Arena is a live-service game, and players notice the moment something breaks. The Services Ecosystem team keeps the platform underneath it fast, stable, observable, and cost-efficient. We're looking for a Senior Software Engineer who thrives in distributed systems, loves a clean and clear dashboard, and wants to help us bring a mature platform into its next era of cloud native tooling.

What You’ll Do:

• Design and implement reliable, scalable solutions in C#/.Net and Kubernetes for Magic: The Gathering Arena to maximize uptime and minimize cost.
• Make telemetry work for us by improving signal-to-noise across Prometheus, Grafana, and Datadog. Curate beautiful dashboards that answer questions before we think to ask them.
• Own service developer experience, tooling, and quality of life for internal customers. Solve problems for your teammates and our players. Rejoice!
• Help build the roadmap by spotting high business impact problems worth solving, writing up proposals, and advocating for them with the team and our partners.
• Support the end to end live product development lifecycle and resolve technical problems as they arise in the production environment.
• Bring technical expertise in cloud native solutions and expand your knowledge in related fields.
• Bring quality, efficiency, and effectiveness to a fun-loving, hardworking, and highly engaged team.

What You'll Bring:

• 4+ years of professional software engineering experience, with time spent building and supporting a live-service product.
• Hands-on experience running scalable workloads on Kubernetes in the cloud.
• Experience with distributed message-driven architectures (RabbitMQ, SQS, Kafka, or similar).
• Infrastructure as code experience, ideally Terraform.
• Real observability experience with Prometheus, Grafana, Datadog, or similar, plus opinions on what makes an alert worth waking up for and easy to grok at 2am.
• A track record of debugging complex issues across service boundaries, using logs, metrics, and a healthy amount of curiosity.
• You'll thrive with us if you are comfortable being multi-threaded, are a self starter, want roadmap influence, and can hold empathy for past decisions while keeping an eye towards modernizing.
• Bonus Points: FinOps (OpenCost/Kubecost), GitOps (Helm, ArgoCD), service coordination (etcd, ZooKeeper), hands on experience with agentic coding and workflows assisted by Claude/ChatGPT/etc.
