• You bring a leadership mindset centred on technical excellence, team growth, and a collaborative culture.
• You exhibit scientific rigor and a business‐focused approach: translating problems into technical strategies and measuring model impact.
• You’re product‐oriented, deeply understanding user needs and how Frontier can deliver value to them.
