Role
Who you are
- Linux Security Expertise – 8+ years of experience with Linux-based production systems, with a strong focus on security at the OS and kernel level (e.g., SELinux, AppArmor, seccomp, namespaces, cgroups, integrity measurement, and TPM)
- Kernel & Hardening – Deep understanding of Linux kernel internals and experience securing kernel subsystems (e.g., syscall filtering, LSMs, audit frameworks, eBPF for security observability)
- Cloud & Infrastructure Security – Experience building or securing core cloud infrastructure (e.g., secure virtualization/KVM/QEMU, hardened images, secure boot, confidential computing, software-defined perimeter, network segmentation, firewalling, identity and access management)
- Security Architecture – Ability to design and implement end-to-end security architectures for large-scale, distributed systems. Familiarity with threat modeling, risk analysis, and mitigation planning for both x86_64 and aarch64 platforms
- Programming Languages – Strong background in C with experience writing secure, high-performance code. Familiarity with Rust, Python, and Go is a plus. Strong track record of delivering security-critical systems from concept to production
- Education – Background in computer science, cybersecurity, electrical engineering, or a related field
Desirable
- Have led and taken full ownership over large, ambiguous, cross team projects from conception to production
- Enjoy moving fast and making a large business impact
- Value working on a team of high performers that hold each other accountable
- Are a self-starter, curious, and not afraid to ask when in doubt
- Are a quick learner, enjoy learning new technologies and methodologies
- Value working on a low ego team that emphasizes strong communication, collaboration, and getting to the right answer as a team
- Care deeply about well-tested code
What the job involves
- Engineering at Lambda is responsible for building and scaling our cloud offering. Our scope includes the Lambda website, cloud APIs and systems as well as internal tooling for system deployment, management and maintenance
- Join a team of industry-leading experts and work alongside the best minds in the field
- Collaborate with top-tier professionals who are shaping the future of the industry
- Design and build foundational Linux security features and infrastructure that protect AI/ML workloads running across thousands of GPUs on modern cloud platforms
- Develop security capabilities for containerized and virtualized environments, including secure boot, system hardening, kernel integrity monitoring, and isolation technologies
Our take
Lambda is a leading provider of deep learning GPU cloud services and computing hardware, founded to aid in providing a solution to the difficult problem of teaching machines how to see and learn.
Their customers include Apple, Intel, Microsoft, Linkedin, and Fortune 500 companies like Microsoft and Amazon Research, so it's no coincidence that Lambda GPU Cloud ranks number three on a google search for 'GPU cloud', behind only NVIDIA and Google itself.
With investments from 1517, Gradient Ventures, Bloomberg Beta, and Razer, Lambda intends on using the capital to expand its cloud and software, engineering teams. As well as looking to ramp up more investments into its GPU cloud, the company is constantly working to improve its hardware products.
