About the Team
At Slack, the Cloud Engineering team is the backbone of our infrastructure — a dynamic group of Cloud Engineers, Financial Analysts, and AWS Subject Matter Experts united by a single mission: keeping Slack fast, reliable, and cost-efficient for millions of users worldwide.
We tackle unique, large-scale challenges that very few engineers ever get to work on. From designing the systems that power global real-time communication to writing software that brings deep visibility into our cloud infrastructure, our work has direct impact every single day. We partner with teams across Slack to maximize cloud value, champion cost-conscious engineering, and build a platform that scales with our ambitions. If you're energized by high availability, resilience, and the right technology choices — this is the team for you.
What you will be doing:
Own software projects end-to-end — from scoping and design through delivery and iteration
Architect and build a next-generation internal platform that gives engineering teams a powerful foundation to innovate quickly
Deliver cutting-edge solutions leveraging containerization, virtualization, and a broad suite of AWS services
Author, extend, and improve Terraform modules that power infrastructure-as-code across Slack
Design and implement an in-house system to deploy, manage, and scale applications for service owners
Partner directly with development teams to identify performance bottlenecks and drive cloud efficiency improvements
Build strong, trusted relationships with service owners — serving as a go-to advisor on cloud best practices
Champion a culture of platform efficiency by sharing knowledge, writing runbooks, and leading internal enablement sessions
Make a measurable financial impact — driving millions of dollars in cloud cost savings annually
What you should have:
U.S. Citizenship or Permanent Residency (Green Card holder). We are unable to provide visa sponsorship for this role.
Genuine curiosity about how cloud infrastructure works — and a passion for sharing that knowledge with your team.
Proven ability to analyze, optimize, and improve reliability in high-traffic, production internet applications
A strong mentoring instinct and commitment to engineering excellence: you lead by example in code reviews, testing, design docs, and debugging
Deep, hands-on AWS experience — broad familiarity across many services with deep expertise in at least a few
Demonstrated experience deploying cloud applications and managing infrastructure-as-code using Terraform and/or CloudFormation
A track record of professional software development you're proud of — you can point to real-world systems you've built and improved
Qualifications:
3+ years of professional experience in cloud engineering or a closely related discipline
Strong computer science fundamentals: data structures, algorithms, distributed systems, programming languages, and information retrieval
Proficiency in one or more functional or imperative programming languages — Python, Go, or PHP preferred
Extensive, production-grade Terraform experience
Hands-on experience operating and optimizing large-scale AWS environments
Bonus Points:
Deep expertise in core AWS services such as S3, IAM, EC2, Lambda, or EKS
AWS Professional or Specialty certification(s)
Experience designing or operating large-scale, high-volume distributed systems
A proven history of driving significant cloud cost reductions at scale
Familiarity with observability tooling (e.g., Datadog, Prometheus, OpenTelemetry) and SRE practices
