Senior Software Engineer (Artifacts Engine)

TL;DR: We're seeking an engineer who is passionate about their craft, has a bias for action, a focus on delivering customer value and low ego. If that’s you, you’ll find a bunch of like-minded people at Cloudsmith.

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.

By developers, for developers: we care about craft, architecture, and enterprise scale.
