Staff Software Engineer (Provenance)

Belfast

TL;DR: We are looking for an engineer to help build a new generation of provenance and build information into the Cloudsmith platform. If you are motivated by solving problems of performance at a massive scale and passionate about your craft, you will find an environment in which you can thrive at Cloudsmith.About CloudsmithCloudsmith 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.The RoleAs a Staff Software Engineer on the Supply Chain Trust team, you will play a key role in building platform capability that gives enterprise customers complete, end-to-end traceability from source code to built artifact. Not just where an artifact came from, but how it was built, what went into it, and exactly how it was used across every pipeline and deployment downstream.Cloudsmith already sits in the middle of how organisations store and distribute software artifacts. This role turns that position into something more powerful: a source of truth. You will build the infrastructure that captures, stores, and surfaces build provenance and pipeline usage data — so that when a customer asks which of their services consumed a given artifact, and what build produced it, the answer is in Cloudsmith, complete and trustworthy.Our TeamWe 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 multiple times per day, and we support a global set of customers who are engineers like us.Key ResponsibilitiesBuild: Design, implement, and ship the provenance ingestion service — capable of accepting provenance and attestation payloads from CI/CD systems, public registries, signed bundles, and customer-uploaded artifacts across a wide range of formats (SLSA, in-toto, SBOM attestations, Sigstore bundles etc).Store: Own the storage architecture for signed provenance metadata.Validate: Build the validation engine that verifies cryptographic integrity and evaluates attestation data against configurable customer trust policies — SLSA level requirements, allowed builder identities, key material, and more.Expose: Deliver clean, well-documented APIs that make provenance data useful to customers and to other parts of the platform — queryable, auditable, and reliable.Collaborate: Work closely with product, customer success, and the wider engineering team to understand how enterprise security teams consume provenance data and translate that into features they love.Quality: Prioritise correctness, security, and observability — this is critical infrastructure customers trust with their software supply chain decisions.Mentor: Share your expertise across the team through code reviews, documentation, and open conversation — a rising tide lifts all boats.Required Experience, Qualities & SkillsWe realise that not everyone will have every experience and expertise in every possible thing. Still, if you have many of the following, we might be a great place to progress your career. We realise that not everyone will have every experience and expertise in every possible thing. Still, if you have many of the following, we might be a great place to progress your career.Domain KnowledgeProvenance & Attestation: You know the landscape: SLSA, in-toto, Sigstore, DSSE, and how attestations are packaged and signed. You do not need to have built signing pipelines, but you must understand their output.Cryptographic Foundations: Comfortable with signing and verification: key material, ECDSA/RSA, certificate chains, OIDC-based keyless signing flows, and transparency logs.SBOM Formats: Familiarity with CycloneDX and SPDX, and how they are packaged as attestation artifacts.Backend & Platform EngineeringExperience: 5+ years of production backend engineering, with real ownership of at least one complex service end-to-end.Technical Proficiency: Strong experience with Python for building backend services and data pipelines. Familiarity with AWS services (e.g. S3, RDS/Postgres, Kinesis, ECS, Lambda) and infrastructure tooling (Terraform).Data Ingestion: Experience designing pipelines that handle varied, schema-evolving, high-volume payloads reliably and at scale — including robust error handling and observability.Data Modelling: Ability to design storage schemas that efficiently represent signed metadata envelopes, artefact graphs, and queryable relationships. API Design: Experience building and versioning APIs consumed by external enterprise customers or third-party integrators.Multi-Tenant Systems: You have built or operated multi-tenant SaaS platforms and understand what data isolation, access control, and audit logging actually require in practice.Iterative Delivery: You understand the importance of shipping early and often and are comfortable making real-world trade-offs between a perfect design and getting something valuable in front of customers.Communication: You are enthusiastic and effective communicator who can bridge the gap between technical and non-technical stakeholders.Mindset: You are deeply passionate about your craft, eager to learn, and comfortable admitting what you don't yet know.Benefits, Location & Work EnvironmentNote: You must be based in Ireland or the United Kingdom and have the right to work independently without requiring sponsorship.HeadlinesA position based in Ireland or the United Kingdom.A competitive compensation package, including equity.With comprehensive health, dental, and vision insurance.Plus, generous annual leave and flexible working policies to suit your lifestyle.Including a professional development budget for conferences and training.In a dynamic, innovative, trust-centric, and supportive work environment.With the opportunity to shape a fast-growing Series B startup (and beyond).Regular (monthly-ish) travel may be required for team meetings.Regular (quarterly-ish) travel may also be required for events and customers.Health and WellnessRegardless of your location, we deeply care about the health and wellness of our staff and their families; a sustainable pace is important to us.
