Our ambition drives us. Our people make it real.
If you’re a challenger in spirit and a champion in action — join us.
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
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.
