Developer, Mobile

Overview

THE ROLE:

We have three openings with the same title.

Build, prototype, and scale next-generation mobile experiences by operating as an innovation engineer, not just a feature implementer. This role exists to transform ambiguous ideas into validated mobile solutions—balancing rapid experimentation with long-term platform integrity. You will help define what should be built, why it matters, and how it can scale across ecosystems. You will bring deep mobile expertise while working at the intersection of product discovery, platform evolution, and technical experimentation, crafting mobile strategy as much as execution.

This is not a traditional mobile delivery role.

You will:

• Work in high-ambiguity environments
• Build prototypes before roadmaps
• Validate assumptions through experiments, data, and learning
• Help transition validated concepts into scalable, production-grade systems

Discovery, Framing & Experimentation

• Partner with product, build, data, and business collaborators to frame problems, not just implement requirements
• Translate loosely defined ideas into hypotheses, experiments, and technical prototypes
• Lead or contribute to discovery sprints, feasibility studies, and technical spikes
• Challenge assumptions and propose alternative mobile experiences or architectures

Prototyping & Validation

• Build rapid prototypes (throwaway and evolutionary) to test user value and technical feasibility
• Instrument prototypes with analytics to measure adoption, performance, and learning outcomes
• Run controlled experiments (feature flags, pilots, A/B tests) where appropriate
• Make informed tradeoffs between speed, quality, scalability, and learning

Mobile Architecture & Platform Thinking

• Build native and cross-platform mobile solutions with platform and ecosystem thinking
• Influence mobile architecture decisions, frameworks, SDKs, and integration patterns
• Balance innovation velocity with long‑term maintainability and platform evolution
• Collaborate on API contracts, data models, and service boundaries

Engineering Excellence

• Write clean, efficient, and maintainable mobile code aligned with platform guidelines
• Implement secure, performant, and accessible user experiences
• Optimize performance across memory, battery, startup time, and responsiveness
• Apply mobile security guidelines, including authentication, encryption, and data protection

Teamwork & Influence

• Collaborate closely with UX, backend, data, and product teams to build cohesive solutions
• Provide technical mentorship and architectural guidance to mobile engineers
• Communicate sophisticated technical ideas clearly to non‑technical collaborators
• Influence direction through prototypes, evidence, and technical insight

Operational Enablement

• Advise on mobile Dev Ops practices, including CI/CD, automated testing, and release strategies
• Support transition of validated concepts from innovation into scaled delivery teams
• Document architecture, experiments, findings, and technical decisions

SKILLS AND BACKGROUND REQUIRED TO BE SUCCESSFUL:

• 5+ years of professional mobile development experience; experience working with diverse technology stacks and multiple projects preferred
• Proven experience across both exploration (early‑stage) and exploitation (scaled delivery) preferred
• Native mobile development (Swift/Swift
  
  UI for iOS and/or Kotlin for Android)
• Cross‑platform development frameworks (React Native, Flutter, or similar)
• Mobile application architecture and design patterns (MVVM, MVC, Clean Architecture)
• API integration, mobile networking, and data synchronization
• Lifecycle management, memory management, diagnostics, and performance optimization
• Proven track record to work effectively with incomplete or evolving requirements
• Strong problem‑framing and systems‑thinking skills
• Experience building prototypes or proof‑of‑concepts—not just production features
• Curious approach with a bias toward experimentation and learning
• Ability to articulate why a solution works, not just how it’s built
• Proven track record of delivering production mobile applications with high quality and performance
• Deep understanding of iOS and Android platform capabilities, limitations, and guidelines
• Exp…
