Flutter Tech Lead
Why this role exists:
This role exists to own and drive the frontend mobile architecture across our flagship products. You’ll help us scale real-time user experiences to millions of active users by delivering high-throughput, low-latency Flutter applications while elevating engineering standards across our development teams.
What you’ll drive:
Strategy & outcomes
Own high-level mobile system architecture, defining patterns that keep our mobile apps stable, modular, and fast.
Translate business goals into robust technical blueprints, making clear decisions on system trade-offs.
Establish engineering benchmarks for app startup times, memory footprint, and frame rates.
Discovery & decisions
Evaluate new mobile technologies, frameworks, and tools to solve complex scale problems before they impact production.
Design and execute migration strategies (including native add-to-app integrations) to modernize legacy codebases seamlessly.
Define and enforce security baselines, including certificate pinning, obfuscation, and anti-tampering logic.
Delivery & execution
Contribute hands-on code to critical, high-complexity systems and core framework libraries.
Lead incident response and root-cause analysis for high-severity mobile production issues.
Optimize app performance, diagnosing UI/raster jank, memory leaks, and CPU-heavy operations using Dart Isolates.
Stakeholder & cross-team alignment
Partner with Product Managers, Heads of Streams, and Team Leads to align technical roadmaps with product release schedules.
Standardize CI/CD pipelines, release automation (fastlane), and store submission processes across all mobile teams.
Align architectural patterns across cross-functional streams to prevent technical fragmentation.
People & technical leadership
Mentor senior and mid-level engineers, running code reviews that raise the overall quality bar.
Support Team Leads in crafting technical Personal Development Plans (PDPs) for mobile engineers.
Drive engineering culture through technical write-ups, architecture reviews, and internal knowledge-sharing sessions.
What makes you a GR8 fit:
Must-have
7+ years in commercial software development, with 3+ years dedicated to Flutter/Dart and hands-on experience in native iOS (Swift) or Android (Kotlin).
Strong system design and architectural thinking, paired with deep mastery of Dart internals (isolates, async, null safety) and Flutter's rendering pipeline.
Deep understanding of software engineering best practices, including state management (Bloc or Riverpod), testing (unit, widget, integration), and monorepos (Melos).
Proven ability to balance technical quality vs delivery speed, taking full ownership and accountability for technical decisions and outcomes.
Hands-on experience with high-frequency real-time data handling (WebSockets, long-lived connections, protobuf/JSON serialization) and mobile security standards.
Effective technical communication skills across engineering and non-engineering stakeholders, with an ability to work smoothly in cross-functional environments (Product, Delivery, Ops).
Mentorship and people development mindset, with experience guiding engineers through code reviews, technical roadmaps, and personal development planning.
Nice-to-have
Hands-on experience with native add-to-app Flutter integration strategies and incremental migrations.
Experience building CMS-driven or Server-Driven UI frameworks.
Familiarity with dynamic localization, per-market feature toggles, deep linking at scale, and multi-jurisdictional app deployment.
Practical experience profiling mobile app performance (DevTools, Impeller engine, jank diagnosis, memory leak isolation).
Familiarity with App Store / Google Play review requirements for gambling and betting applications.
