• Strong hands‑on background in designing, building, and scaling SaaS, cloud‑based, or API‑driven products.
• Strong understanding of software architecture, scalability, reliability, security, and engineering best practices.
• Ability and willingness to dive deep into technical problems, architecture, and critical engineering decisions when needed.
• Proven track record of improving engineering execution, processes, and team performance.
• Strong ability to partner with Product, Design, and business leadership to balance technical and business priorities.
• Excellent communication and leadership skills, with experience working with distributed/global teams.
