• Strong software engineering capability in at least one modern programming language.
• Knowledge of reliability engineering, observability, incident response and disaster recovery.
• Excellent communication skills with the ability to influence technical strategy and collaborate across teams.

Experience in any of the following would be beneficial:

• Amazon Bedrock, AI governance or agent-based AI solutions.
• Secure adoption of AI-assisted development tools.
• CrowdStrike Falcon Cloud Security, Amazon Macie or related security platforms.
• Multi-cloud environments including Azure and/or Google Cloud.
• Secure multi-tenant SaaS architectures.
