The title 'Mobile Engineer' carries no explicit seniority level, but the scope — end-to-end architecture ownership, cross-functional alignment, subject-matter expertise, and participation in hiring — is consistent with a Senior individual contributor.
Swift, Kotlin, and React Native are listed as a single interchangeable requirement ('strong proficiency in Swift, Kotlin, or React Native'); Swift is used as the primary name with the others in alternatives. iOS and Android are similarly interchangeable ('iOS and/or Android'), with iOS as primary.
The degree requirement states 'B.S. or M.S. in Computer Science or equivalent degree/experience,' which accepts equivalent experience in lieu of a formal degree — treated as no hard degree gate.
AI tool integration and ongoing AI skill development (prompt engineering, agent orchestration) appear in the required 'What We Look For In You' section and are treated as hard gates.
DeFi protocols and wallet integrations appear under 'Nice to Haves' and are preferred only.
