02 Why we’re hiring

Cranium secures the AI revolution through an award-winning AI Security and AI Governance platform that supports organizations of all sizes across their entire AI supply chain — from AI entry through runtime. The platform helps teams identify, manage and mitigate AI-related risks to ensure security, compliance and responsible innovation. We’re powered by “Craniacs”: a team committed to redefining the standard for AI excellence.

03 About the role

Cranium builds products to secure AI, developing cutting-edge AI/ML methods that push the state of the art. As a Senior Software Engineer
, you will be a key member of the engineering team responsible for developing and maintaining the core platform of the Cranium architecture.

Your work will focus on building scalable, multi-tenant systems that detect and monitor how AI is used across enterprise environments. You’ll work primarily with our backend platform and cloud infrastructure, collaborating with frontend engineers, machine learning engineers and product managers to deliver robust solutions to our enterprise customers.

• Design, develop and maintain scalable multi-tenant platform services and APIs within Azure and other cloud platforms.
• Work with machine learning engineers and product managers to develop backend services that power our AI security features.
• Implement and maintain containerized applications using Kubernetes and related orchestration technologies.
• Contribute to database design and optimization for high-volume enterprise workloads.
• Leverage AI-assisted development workflows and code generation tools to build enterprise-grade software.
• Support customers through technical issues, escalations and feature requests alongside the customer success team.
• Participate in code reviews and ensure code quality adheres to best practices.
• Balance new feature development with platform maintenance and refactoring.

04 Who you are

Customer-focused — you start from the problem the customer is trying to solve, and measure your work by whether it actually helps them.

Willing to put your ego aside — you care more about the best outcome than being right, welcome feedback and give credit generously.

Collaborative and low-drama — you work well across engineering squads, product and customer success, and raise issues directly and constructively.

05 What we look for

• Containerization beyond Kubernetes — Docker, container registries, deployment patterns.
• Infrastructure as Code (Terraform, ARM templates, Cloud Formation).
• Queue and cache services (Redis, Memcached, Azure Service Bus).
• Background designing secure, highly available, fault-tolerant distributed systems.
• Familiarity with AI/ML concepts and strong algorithmic thinking.
• Strong analytical skills, tying technical decisions to business impact.
• Deep familiarity with agentic development tools — prompting patterns, and knowing when to trust or verify their output.

06 What we offer

A chance to make a real contribution to the future of AI, alongside impossibly talented people who share the mission. Our biggest asset is inclusion — a diverse community is how we succeed.

• Competitive salary & equity. Earn a competitive salary and own a real stake in Cranium through equity.
• Market-leading health, dental and vision coverage for you and your dependents.
• Flexible time off & family leave. A flexible time-off policy, plus paid parental and family leave when you need it.
• An individual learning budget — lifelong learning is one of our values, not a perk.
• A 401(k) program to help you save for the future, set up whenever you’re ready.
• The Craniacs. A multidisciplinary team that plays nice, ships hard and has a lot of fun doing it.
