About Cloudsmith

Cloudsmith is transforming how organizations handle software artifacts and secure their supply chains. As a cloud native, multi-tenant platform, we enable organizations to build software better, through best-in-class artifact management and software supply chain security. Our vision is to become the software supply chain itself, powering the future of software delivery.

We are the world's most potent artifact management platform, built by developers for developers. Our platform supports over 30 formats spanning languages, container formats, and operating systems, with enterprise-grade features, including vulnerability and security scanning, world-class policy management and enforcement, and web-scale to handle the Fortune 500. Organizations integrate Cloudsmith as critical infrastructure into their development, deployment, and distribution pipelines, trusting us to protect and accelerate, regardless of scale.

Backed by top-tier investors and on a trajectory toward IPO and beyond, we're building mission‑critical infrastructure that powers software delivery for organizations worldwide. We operate at the cutting edge of cloud‑native technology, tackling complex distributed systems challenges that directly impact millions of developers. Now is an exciting time to join us as we revolutionize how organizations deliver and secure software and help write the next chapter of our rocketship growth story.

As a Senior Software Engineer in the Platform Edge team, you'll build the infrastructure that powers fast, reliable package delivery at a global scale. You'll design and implement edge caching systems, CDN optimisations, and distributed networking solutions that ensure our customers can access their packages quickly and reliably from anywhere in the world. This is a rare opportunity to shape the future of our edge infrastructure by designing greenfield solutions that unlock the next stage of global scale.

Your work will help teams ship with confidence—knowing their packages are delivered with optimal performance and availability.

We are four teams responsible for building application capabilities and the underlying platform upon which Cloudsmith is founded. We operate in a highly collaborative environment, where people with different skills come together to make things happen. We each contribute to an environment where curiosity, support, transparency, and bias for action reign. We have a modern CI/CD approach, deploying several times per day, and we support a global set of customers who are engineers like us.
