Role Summary

As a Senior Site Reliability Enginee r (SRE) on the Infrastructure and Ops platform team, you will help design, build, and deploy the tools used to empower our development teams and production applications. We’re looking for talented engineers to help grow our operational maturity, as well as equally enjoy mastering cloud-native technologies to build and support our microservice architecture growth and reliability.

As a Developer Efficiency and Experience focused SRE, you will be responsible for helping improve the efficiency of engineering and our development teams by supporting the SDLC and workflows of our developers, ranging from writing supporting application code, automation, and most importantly, empowering developers to have the confidence to create, deploy, and manage their services end-to-end inside the platform.

What you’ll do

• Build and maintain tooling to support our applications in Kubernetes and in the Google Cloud Platform.
• Work with development teams to help them build, ship, and deploy services and applications with ease and confidence, and promote service resilience and reliability.
• Help ensure smooth operations of our production environments, and work with developers to help debug complex issues as they arise. This includes creating and facilitating the capturing and monitoring of the 4 golden signals in our applications.
• Help to create a self-service platform by working with the rest of the SRE and infrastructure team to accelerate and promote developer velocity, including service catalogs, repository tooling and documentation. We believe in the self-service model and treat the development team as our internal customers, including listening to feedback, seeking out improvements, and quickly iterating to continually provide value.
• Participate in a shared on-call rotation schedule. We believe in service end-to-end ownership, and as such, both development teams and SRE participate in on-call.  Our SRE team is responsible for maintaining and being on call for our infrastructure environments and ensuring primary site uptime.

Required Qualifications

• 5+ years of experience in an SRE role or similar.
• Experience deploying, managing, and debugging applications in a Kubernetes environment. We leverage Helm and Crossplane heavily to deploy our applications.
• Experience building, securing, and managing container images.
• Experience working with Cloud-based environments, and interacting with Cloud services such as CloudSQL databases, Pub/Sub, Memorystore, and others.
• Familiarity with Infrastructure-as-code Tools, such as Terraform, Crossplane, or similar.
• Experience with tools and solutions used to monitor the 4 golden signals (latency, traffic, errors, and load), including Prometheus, Grafana, and OpenTelemetry.
• Familiarity with a monorepo, trunk-based development model with monolithic build tooling and CI/CD, with a strong desire to achieve Continuous Deployment. Familiarity with CI/CD systems such as GitHub Actions, ArgoCD, or similar.
• Ability to communicate and support developers with empathy to support their day-to-day roles, seeking ways to automate and promote self-service as necessary to continually enable developers to move with higher velocity and confidence through the entire SDLC.

Preferred Qualifications

• Experience building and supporting a gRPC microservice architecture. Familiarity with Kubernetes Service Mesh, such as Istio or similar, to support our microservice architecture observability, multi-cluster routing, and network efficiency is highly desirable.
• Ability to interface with application code to help assist in introducing best practices, golden path standardization, shared libraries, etc. The majority of our applications are written in Go. Python and Scala are present to a lesser degree.
• Familiarity with Application Security tooling, such as dependency scanning, static analysis, and other linting tooling to help shift security left in the SDLC and CI process, and bridge engineering practices with our Security Operations team.
• Familiarity and comfort with Linux-based environments.

Qualities

• Have a passion for clean, concise architecture and enjoy working in a GitOps-based environment.
• Comfortable with projects that have a large degree of uncertainty and risk
• Desire to collaborate with and advise product management and leadership to balance long-term maintainability of software against rapid development, as well as clearly communicate BCDR implications.
• Understands and practices the principles of continuous delivery to ensure quick, safe, and sustainable development in the face of changing priorities and uncertainty

What will make you stand out

• Basic understanding of infrastructure operations, including load-balancers, ingresses, routing, DNS, and VPC design. We operate several data center environments across the globe in addition to our cloud infrastructure.
• Not being afraid to dig into code to better understand how our applications work to better facilitate testing, integration, and development environments, to help instrument metrics, or to improve service reliability.
• Deep understanding of how to optimize and support web-based applications and help protect public-facing assets with tooling such as anti-DDoS and Web Application Firewall technologies.

Our target salary range for this role is between $145,000 USD and $195,000 USD + bonus eligibility and equity.

In addition to our great compensation package, our benefits are effective on day one and include, but are not limited to: 401k match, health, vision, dental, and more! Please see our careers page for more details.
