Build the future of data. Join the Snowflake team.

Snowflake customers have more than 3.9 billion queries and more than 515 million data workloads that run each day. Build the future of data. Join the Snowflake team.

The Snowflake Cloud Engineering team is a global team of high performing engineers focused on building best in class tooling, automation, and a scalable infrastructure platform to run the Snowflake service. The team’s focus areas include Snowflake's global scale multi-cloud infrastructure, core platform services, edge traffic delivery, and reliability engineering. The team also automates the deployment of the Snowflake production service across dozens of regions and major cloud providers.

We are looking for talented and passionate Senior Software Engineers to join our Traffic & Edge team. Snowflake’s Traffic and Edge infrastructure consists of reverse proxy and load balancing systems running in multiple public clouds. These systems deal with DNS management, TLS termination, load balancing, CDNs, and traffic routing. Every incoming request into Snowflake flows through or relies on these systems. The critical nature of these services demands a very high level of reliability.

As more and more customers globally start using Snowflake in a variety of ways, the Edge will need to support more features and sustain higher throughput while remaining reliable. We have been on a significant growth journey at Snowflake, with the volumes of data constantly accelerating, and as such there will be substantial opportunities to drive reliability, security, and performance improvements at the Traffic & Edge layer. Further, Snowflake’s focus on building a truly multi-cloud service drives us to create elegant abstractions to enable rapid iteration and product delivery. Interested in joining us to solve these complex platform engineering challenges?


  • Design, lead and own significant projects with an impact felt far beyond your team.
  • Contribute to the design and operation of our highly reliable, secure, scalable, and performant infrastructure
  • Develop the software to grow our fleet of services and deployments
  • Participate in our on-call rotation and ensure uptime of services
  • Use your deep experience and problem solving skills to help investigate and fix production issues, and drive blameless incident post-mortems to document learnings and prevent recurrences
  • Plan and lead complex technical projects while partnering with a wide variety of teams within the company


  • BS/MS in Computer Science/Engineering or related major, or equivalent experience.
  • A track record of planning, running and delivering cross team projects
  • Experience with at least one advanced programming language such as C++, Java, Go, Python
  • Experience with running HTTP, DNS and TLS infrastructure
  • Hands on experience with one of more public cloud providers such as AWS/Azure/GCP
  • Experience with Traffic/Edge Engineering or Cloud Networking
  • Experience with automating operations (e.g., software deployments, config changes) at scale
  • Hands-on experience with Infrastructure-as-Code (e.g., Terraform, Ansible, AWS CloudFormation, Chef, Puppet)

Experience with core SRE/Production Engineering best practices (e.g., designing for operability and scalability, adopting SLOs, eliminating toil, leading incident responses, driving blameless post-mortems)

Evidence of engineering leadership through design ownership and reviews, mentoring, contributing to technical roadmaps, and driving process improvements

We value a strong growth mindset at Snowflake, so we would love to hear from you even if you don’t meet all the requirements above!
