Role
Who you are
- ✅ 5+ years of real-world software engineering experience
- ✅ Deep understanding of data structures, algorithms, compilers, toolchains, and how the pieces fit together
- ✅ Fluency in containers, Docker, Kubernetes, and their ecosystems
- ✅ Experience with Terraform or other IaC tools, and a knack for modular, reusable infra
- ✅ Strong automation chops—Python, Go, Bash, or similar
- ✅ Excellent communication, autonomy, and the instincts to know when to ask for help
Desirable
- 💡 Contributor to open-source projects (especially in the container or infra space)
- 🔥 A track record of bringing order to chaos in fast-moving environments
- 🧪 Curiosity, initiative, and the courage to try weird things that just might work
What the job involves
- If you're the kind of engineer who thrives on clean systems, tight loops, and big technical challenges, this one’s for you
- You’ll be joining the Guarded Containers team—the builders and stewards of Chainguard Images, our flagship product
- We’re talking about the base layer of trust for supply chain security—and you’ll be shaping the foundation
- We're growing fast and scaling even faster. That means we need folks who can not only write great code but also think 10x:
- How do we evolve our image tooling infrastructure as demand surges?
- What new features do our customers need before they know it?
- How do we enforce quality with automation instead of overhead?
- If you’re excited about working on one of the most technically sophisticated products in the secure software supply chain—and doing it with a team that’s collaborative, opinionated, and execution-focused—you’ll love it here
- Build the Future of Chainguard Images
- Design and implement new features that make our container images even more secure, performant, and scalable
- 🧰 Level Up Our Tooling and Infra
- Develop robust internal systems that scale with us—everything from build pipelines to container registries to custom tooling that only we could dream up
- 📏 Codify and Enforce Product Quality
- Define standards, write tests, and ship tooling that helps us stay high-quality and high-velocity at the same time
- 🤝 Collaborate Across Boundaries
- Work closely with engineering, product, customers, and leadership to help define roadmap and shape the future of the product
Our take
Developers rely on open source code and apps in their day to day work, but when the provenance of the code is unknown this creates potential weaknesses that cybercriminals can exploit. Chainguard exists to build security into the coding supply chain by making it possible for companies to enforce security policies based on auditable signatures baked into the code, and by providing a security-first set of container images with no known vulnerabilities for cloud app developers.
In the wake of huge cyber attacks like the Log4j vulnerability and Solarwinds breach, software supply chain security has been an area of major focus for startups hoping to solve problems in this sector. However, most of these focus on scanning and detection of threats. Chainguard's approach comes from the other end of the process, focusing on building security into the software itself. It was built by former Google engineers aware of software developers existing workloads, so is designed to be easily installed and integrated into existing automation systems like Terraform.
Chainguard completed a Series C funding round led by Lightspeed Ventures in 2024, minting it as a new Unicorn on the cybersecurity scene. It is using this funding to expand its go-to-market internationally and expand its Chainguard Images product.
