TL;DR: We’re seeking a platform-minded software engineer to build and own the developer-facing tools that sit at the heart of how engineers integrate with 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 Fortune 500 companies, 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.
In this role, you'll be responsible for building and maintaining the tools that many of our customers use every single day - in some cases, they're the only part of Cloudsmith that those engineers ever touch. That means the CLI, Terraform provider, MCP integration, IDE extensions, and more. These are durable, platform-grade interfaces that need to evolve carefully and responsibly alongside the core Cloudsmith platform - built to last, and owned for the long term.
You'll work closely with Customer Success, Solutions Engineering, and real external customers to make sure what you build reflects how developers actually work in the wild.
If you love building tools that other engineers rely on, think carefully about interface design and ergonomics, and get satisfaction from making complex things feel simple - this role is for you.
Hands-on experience building or contributing to developer-facing tooling - CLIs, SDKs, Terraform providers, language server protocols, IDE extensions, or similar. You don't need to have built all of these, but you should feel at home in this ecosystem.
Experience with AI-assisted development tools and workflows, and an interest in how they’re reshaping the way engineers build software.
At Cloudsmith, our values shape how we make decisions every day. Here's what we mean by that in the context of this role:
Automate everything. We believe that if it can be automated, it should be. You'll apply this to your own work - releases, testing pipelines, validation - and help raise the bar for the whole team.
Collective ownership. You'll take responsibility for what you build long-term, respond when things break, and treat the entire platform as something you have a stake in - not just your corner of it.
Transparency. We share what's working and what isn't, openly. You'll be honest about tradeoffs, flag problems early, and communicate progress in a way that keeps stakeholders - internal and external - genuinely informed.
Bias for action. We believe in pragmatism first, perfection later. You'll know when to move quickly with a good solution rather than waiting for an ideal one, and you'll build the kind of instincts that make that call reliably.
Just better. We believe everything can and should be improved upon. You'll bring a continuous improvement mindset to your work - questioning defaults, proposing refinements, and raising the bar without being precious about it.
Customer collaboration. We stay close to the people who use what we build. You'll treat customer feedback as a genuine input to your work, and care deeply about the experience of the engineers on the other side of your tools.
This role offers the chance to directly shape the developer experience for one of the most critical layers in the software supply chain. As a member of a newly established squad with a clear mandate and growing capacity, you'll have meaningful influence over the tools, standards, and culture from day one. From startups to Fortune 500 companies, your work will directly impact how organizations control and secure their software supply chains.
This is a foundational hire for a new squad, which means the growth ceiling is high. As the team matures and the scope of the roadmap expands, there is a clear pathway for growth.
For engineers who love the craft and want to go deeper, there's a natural progression toward a senior or staff engineering track - owning architectural decisions, mentoring newer engineers, and shaping the technical direction of developer tooling as a platform capability.
Note: You must be based in Ireland or the United Kingdom and have the right to work independently without requiring sponsorship.
Regardless of your location, we deeply care about the health and wellness of our staff and their families; a sustainable pace is important to us. In addition to generous annual leave (PTO), we offer health and well-being benefits and flexible, family-friendly work policies.
You will have an enormous opportunity to learn new skills alongside your colleagues, and your continued professional development is essential to us because it's important to you. We will support you with budgets for equipment, training, books, conferences, travel, and certifications. The more powerful you become, the better for all of us.
