# Flutter Tech Lead - Company: [Gr8tech]() - Location: Anywhere - Team: Frontend Tech Lead - Posted: September 9, 2026 ## Job description **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. Call it what it is: the iGaming Platform for Champions. 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. **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** * 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. ## **Why you’ll love working here:** **Benefits Cafeteria** — annual budget you allocate to: Sports • Medical • Mental health • Home office • Languages. **Work-life & support** * Paid maternity/paternity leave + monthly childcare allowance. * 20+ vacation days, unlimited sick leave, emergency time off. * Remote-first + tech support + coworking compensation. * Team events (online/offline/offsite). * Learning culture with internal courses + growth programs. ## **Our culture & core values:** GR8\_TECH culture is how we win — through trust, ownership, and a growth mindset. We move fast, stay curious, and keep it real, with open feedback, room to experiment, and a team that’s got your back. **FUELLED BY TRUST**: we’re open, honest, and have each other’s backs. **OWN YOUR GAME**: we take initiative and own what we do. **ACCELER8**: we move fast, focus smart, and keep it simple. **CHALLENGE ACCEPTED**: we grow through challenges and stay curious. **BULLETPROOF**: we’re resilient, ready, and always have a plan. ## Apply [Apply on Gr8tech]() Canonical job page:
