Job description

Role overview

This leadership role owns the mobile frontend architecture for flagship consumer products serving millions of active users. The position combines hands‑on Flutter engineering with strategic technical direction, driving high-throughput, low-latency mobile experiences at scale. It suits an experienced mobile architect who thrives in fast‑paced environments and can elevate engineering standards across multiple development teams.

Responsibilities

• Define high‑level mobile system architecture, ensuring applications remain stable, modular, and performant.
• Translate product objectives into technical blueprints and make clear decisions on system trade‑offs.
• Establish engineering benchmarks for app startup time, memory footprint, and frame rates.
• Evaluate emerging mobile technologies and design migration strategies, including native add‑to‑app integrations.
• Lead incident response and root‑cause analysis for high‑severity production issues.
• Diagnose UI jank, memory leaks, and CPU‑heavy operations using Dart Isolates, and optimize accordingly.
• Partner with product and delivery leaders to align technical roadmaps with release schedules.
• Standardize CI/CD pipelines, release automation, and store submission processes across mobile teams.
• Mentor engineers through code reviews and support personal development planning.

Requirements

• 7+ years in commercial software development with 3+ years focused on Flutter/Dart and hands‑on native iOS (Swift) or Android (Kotlin) experience.
• Strong system design skills and deep mastery of Dart internals (isolates, async, null safety) and Flutter's rendering pipeline.
• Expertise in state management (Bloc or Riverpod), testing (unit, widget, integration), and monorepos such as Melos.
• Experience handling real‑time data at scale (WebSockets, long‑lived connections, protobuf or JSON serialization) and mobile security baselines.
• Demonstrated ability to balance technical quality against delivery speed, with full ownership of decisions and outcomes.
• Strong communication skills for collaborating across engineering, product, and operations stakeholders.
• Mentorship experience guiding engineers through code reviews, technical roadmaps, and development planning.

Nice to have

• Hands‑on experience with native add‑to‑app Flutter integration and incremental migrations from legacy codebases.
• Background building CMS‑driven or server‑driven UI frameworks.
• Familiarity with dynamic localization, per‑market feature toggles, deep linking at scale, and multi‑jurisdictional deployment.
• Practical profiling experience using DevTools, the Impeller engine, jank diagnosis, and memory leak isolation.
• Knowledge of App Store and Google Play review requirements for regulated gaming and betting applications.

Benefits and work setup

• Annual benefits cafeteria budget allocated to sports, medical, mental health, home office, and language learning.
• Paid parental leave and a monthly childcare allowance.
• 20+ vacation days, unlimited sick leave, and emergency time off.
• Remote‑first setup with technology support and coworking compensation.
• Team events held online, offline, and through periodic offsites.
• Internal courses and growth programs supporting continuous learning.
