The Role_
// Masabi is hiring a Chief Architect, a collaborative, deeply technical and hands-on leader to shape our technology strategy, embed architectural standards and lead our Data and AI vision for our multi-tenant SaaS platform.
You’ll be Masabi’s key architectural partner, trusted for your clarity, technical insight, and ability to bring people with you. You’ll work across all levels of the organisation to ensure that our architecture supports scalability, resilience, security, and developer experience as we grow.
You’ll partner closely with the CPO and VP of Engineering to co-own strategic implementation, switching easily between 10,000-foot architecture and working in the codebase. You’ll lead our team of four Principal Engineers, supporting their growth, aligning them on technical direction, and fostering collaboration across squads and domains.
You’ll also champion thoughtful, responsible adoption of AI/ML capabilities, both as product features and to enhance developer workflows, embedding AI in ways that deliver meaningful value and long-term impact.
