The world of work as we know it is changing and we're looking for Trailblazers who are passionate about bettering business and the world through AI, driving innovation, and keeping Salesforce's core values at the heart of it all.

Ready to level-up your career at the company leading workforce transformation in the agentic era? You're in the right place! Agentforce is the future of AI, and you are the future of Salesforce.

Slack is looking for a Senior Software Engineer to lead the evolution of our Source Control Management (SCM), Test infrastructure, and CI systems. This is a high-leverage role where you will be a key contributor to the systems that hundreds of Slack engineers use every day to ship code to millions of users.

We are a deeply technical group that lives and breathes Infrastructure as Code, leveraging a stack that includes AWS, Terraform, Chef, Ansible, Packer, Go, and Python
. In this role, you will lead complex projects to ensure our systems are scalable, reliable, and secure. You ll work across two specialized domains: one managing the macOS/Windows environments for Mobile and Desktop CI/CD on AWS, and the other managing our on-premise Git Hub Enterprise and Linux-based Buildkite/Git Hub Actions runner fleets.

We re looking for a technical leader who can bridge these environments. As a Senior Engineer, you won t just be writing code; you will be a subject matter expert who scopes flexible solutions, mentors early-career engineers, and partners with stakeholders to improve developer velocity across the entire company.

• Mentorship & Culture: Serve as a culture steward for the team, mentoring early-career engineers, providing high-quality code reviews, and fostering an inclusive environment.
• Operational Excellence: Participate in on-call rotations and serve as an Incident Commander, leading postmortems and driving long-term fixes to prevent recurrence.

• Experience: 5-8+ years of experience in Dev Ops, Infrastructure, or Site Reliability Engineering, with a track record of leading projects in large-scale environments.
• Cloud & IaC Expertise: Deep hands-on experience with AWS and a strong command of Infrastructure as Code tools like Terraform, Chef, or Ansible
  .
• Systems Knowledge: Proficiency in managing SCM systems (Git Hub Enterprise) and modern CI/CD platforms (e.g., Buildkite, Git Hub Actions) and a passion for improving developer workflows and productivity.
• Forward-Thinking Mindset: A strong interest in the intersection of AI and Dev Ops. You should be comfortable…
