  • You will be responsible for designing, building, deploying, and maintaining CI systems and environments, with shared ownership with the development teams.

  • We are embracing DevOps practices, where the CI Infrastructure team develops CI systems, automation, tooling, and workflows and has a consulting/mentoring role in enabling developer teams to own the whole lifecycle of the software they are making.

  • Provide excellent customer service by understanding and addressing the teams’ needs and expectations through effective communication and collaboration while learning about our infrastructure.
  • Write CI pipelines on your own.
  • Learn how teams are using CI and what are the biggest challenges

In the first six months, expect to:

  • Support and improve CI infrastructure design, architecture, and implementation support.
  • Participate in the on-call rotation schedule (during business hours) to support CI-related help requests.
  • Report any performance issues faced by the CI systems, drill down to find out what caused it, and coordinate with other teams to resolve them.

In the first year, expect to:

  • Communicate with key partners on project engagements.
  • Partner closely with our teams in the engineering area to develop CI infrastructure automation and management solutions with a strong focus on scalability, observability, automation, reliability, security, and quality.
  • Plan and coordinate improvements related to CI infrastructure.
  • Participate in technology initiatives that enable developers to deliver their services to our customers with minimal friction and a high degree of quality.


  • Experienced in supporting and improving CI infrastructure design, architecture, and implementation support.
  • Solid understanding of Linux debugging, networking routing, IP addressing, Load Balancing, and VPNs.
  • Hands-on experience with Jenkins and GitHub Actions, or other CI tools.
  • Proficiency with bash and scripting such as Ruby, Python, or similar.
  • Hands-on experience with system and application metric collection and alerting services like Grafana, Prometheus, or others. A keen focus on what makes a system observable.
  • Experience with Docker, Docker Compose, and building optimized docker files.
  • Experience with Google Cloud platform.
  • Experience with Kubernetes environments: production operations, troubleshooting, debugging, cluster provisioning, and management.
  • Experience running RDBMS is an advantage, especially PostgreSQL knowledge.
