Deep knowledge of software supply chain security, including build system hardening, artifact signing, dependency management, and vulnerability scanning
Hands-on experience implementing “shift-left” security practices, integrating security into CI/CD, IaC, and developer workflows
Familiarity with incident response, threat modeling, and risk assessment processes, especially in fast-moving engineering environments
Proficiency in at least one systems language (C, C++, Go, or Rust) and one scripting language (Python, Bash, or similar)
Strong collaboration skills, with the ability to work closely with developers, IT, and leadership to embed security into everyday operations
Excellent written and verbal communication skills, you can explain complex security issues clearly to both technical and non-technical audiences

Develop and implement security policies and procedures for evaluating new technologies, software acquisitions, and integrations
Collaborate with engineering, IT, and procurement teams to ensure secure deployment and sourcing practices
Monitor for and investigate security incidents, coordinating response, containment, and remediation across teams
Educate and train staff on security best practices, awareness, and secure development principles
Contribute to the creation and maintenance of disaster recovery and business continuity plans to ensure resilience

Our take

AI development is booming, but the tools behind it? Not so much. Developers are often stuck dealing with messy, disconnected systems that slow everything down and bump up costs.

To address this, Modular has developed a unified AI platform that streamlines the development process. It's AI Engine enhances the performance of models on CPUs and GPUs, supporting popular frameworks like TensorFlow and PyTorch. And on top of that, it's built Mojo, a programming language that's as easy as Python but much faster (35,000 times faster).

In 2023, the company raised an impressive $100M to power its mission. It's been using this funding to grow its team, support more hardware, and push Mojo even further. With the hopes of making AI development faster, smoother, and a whole lot more fun for everyone.
