About Cloudsmith

Cloudsmith is building the operating system for the modern software supply chain.

We run a global, fully managed, multi-tenant SaaS platform that helps organizations, from startups to the Fortune 500, secure, govern, and distribute software artifacts at scale.

Worldwide, our customers use Cloudsmith as a critical infrastructure control plane for CI/CD, developer workflows, security controls, compliance, and software distribution, supporting 30+ formats and ecosystems across languages, containers, and operating systems.

We recently raised our Series C to accelerate Cloudsmith 2.0: deeper artifact intelligence, stronger policy and provenance, faster package-aware delivery, and infrastructure built for engineering teams, as well as the modern AI-driven software factory.

Backed by top-tier investors and on a trajectory toward IPO, we're building mission-critical infrastructure that powers software delivery for organizations worldwide. By developers, for developers: we care about craft, architecture, and enterprise scale.

The Role

We are building a team that is responsible for the developer experience. On a daily basis, we work with our customers and the developer community to ensure they are building software that is efficient and secure across the whole supply chain. Our team helps customers troubleshoot and investigate issues, diagnosing and resolving core product-related issues.

We expand and enhance their experience through the development and maintenance of 3rd party integrations that extend our API, CLI, and Webhook capabilities, while curating a public knowledge base to support customers to independently resolve common issues.

Cultural Values We're Looking For

• Relentless curiosity + continuous learning: You are always eager to learn, improve, and challenge assumptions.
• Bias for Action + Ownership: You take initiative, move fast, and own problems end-to-end. You're not afraid to roll up your sleeves, even when challenges are outside your comfort zone.
