Role overview
GR8_TECH builds B2B iGaming platforms for operators who play to lead. We deliver full-cycle, high-impact tech designed to scale — from seamless integrations and expert consulting to long-term operational support. Our platform powers millions of active players and drives real business growth. With 1000+ GR8 people across locations and time zones, we don't just ship technology — we help operators build success stories across brands, markets, and geos. This role exists to own and drive the frontend mobile architecture across our flagship products, helping 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.
Responsibilities
- 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
- 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
- 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
- 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
- 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
Requirements
- 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
Benefits
- Benefits Cafeteria — annual budget you allocate to: Sports • Medical • Mental health • Home office • Languages
- Paid maternity/paternity leave + monthly childcare allowance
- 20+ vacation days, unlimited sick leave, emergency time off
- Remote-first + tech support + coworking compensation
