• Proven experience designing and evolving multi‑tenant SaaS platforms.
• Strong understanding of modern architectural patterns, including event‑driven systems, microservices, domain‑driven design, data pipelines, and API ecosystems.
• Experience making long‑term product architecture decisions, including feature evolution, scalability, and maintainability of a platform over time.
• Strong hands‑on experience in cloud‑native architecture – designing, building, and operating scalable solutions (AWS preferred; Azure acceptable).
• Ability to balance technical depth with pragmatic decision‑making in a product environment.
• Experience working closely with product and engineering teams in a product‑led organization.
• Excellent communication and stakeholder collaboration skills (verbal and written in English).
