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
