Senior Software Engineer, Native Mobile

Responsibilities

• Accelerate every other Frontend engineer at Coinbase by defining architectural patterns, improving build speeds, and defining optimal development workflows.
• Own the development of core app surfaces in Swift and Kotlin, translating existing React Native flows into performant native implementations that meet strict performance budgets, and setting the project-level quality bar through code and design reviews.
• Build within the AI-assisted code generation loop, orchestrating AI as a force multiplier by leveraging LLM-driven translation while applying native mobile expertise to validate architecture, catch edge cases, and ensure production-quality outputs.
• Partner with product teams during onboarding to review native PRs, challenge suboptimal patterns, and attack slow paths the team has accepted, such as flaky tests, painful deploys, or ambiguous handoffs between native and React Native codebases.
• Drive performance optimization across device tiers, architecting robust solutions through trade-off analysis to eliminate loading indicators, scroll jank, and stall counts, with particular attention to low-end Android devices.
• Contribute to the dual-app parity strategy during the transition period, identifying and killing technical debt that matters while ensuring feature and bug fix synchronization between codebases.
