Senior Software Engineer

Senior Software Engineer | Backend / Distributed Systems Most backend roles are about building another feature into an established product. This one is about helping build the infrastructure that modern software depends on. Cloudsmith is creating the platform companies use to securely manage, govern and distribute the software packages, containers and dependencies flowing through their organisation. It sits directly in the path between developers writing code and that software reaching production. That creates some genuinely difficult engineering problems: • Designing distributed systems that remain reliable under serious scale • Moving and serving huge volumes of software artifacts globally • Building secure, multi-tenant backend platforms • Improving performance, resilience and observability across complex systems • Making sensible architectural decisions where there is no obvious playbook • Balancing engineering quality, customer impact and the realities of a fast-growing product They are looking for strong backend engineers rather than one rigid profile. You might come from platform engineering, developer tooling, cloud infrastructure, security products, databases, distributed systems or high-scale SaaS. The important part is that you enjoy understanding how systems really work, debugging difficult problems and taking ownership beyond the code you personally write. You will join a highly capable engineering team, work on problems with real technical depth and have meaningful influence over how the platform evolves. This is not a maintenance role, and you will not be buried under layers of process. It is an opportunity to help shape a category-defining engineering product at the point where software delivery, cloud infrastructure and supply-chain security meet. Interested?
