• Jest and understanding of E2E testing with Cypress / Playwright
• Git, code review culture, Jira or similar tools
• Experience with payment integrations or financial data
• Experience mentoring developers and reviewing code
• Experience communicating directly with clients without a PM as the only communication layer

Communication is important
You should be comfortable communicating directly with clients and gradually taking more ownership on the business side.

We expect:

• English B2+, confident spoken communication
• Ability to participate in client calls independently
• Ability to communicate with CTOs, founders, and C-level stakeholders in a structured and clear way
• Ability to explain technical decisions, risks, trade-offs, and technical debt in business terms
• Confidence to challenge a poor idea or unrealistic scope respectfully and without creating conflict
• Clear written communication and documentation
• Calm communication in discussions and ability to defend technical decisions when needed
   

AI-assisted development experience is required
We actively rely on AI in our engineering workflow, so we’re looking for hands-on experience, not just familiarity with the tools.

You should have:

• Daily experience with Claude Code, Cursor, Codex, or similar agentic tools
• Experience preparing context for agents: project rules, CLAUDE.md / cursor rules, MCP integrations, task decomposition
• Ability to critically review AI-generated code and identify hallucinations, unsafe patterns, and unnecessary abstractions
• Understanding of where AI saves engineering time and where it can create technical debt
• Ability to build an effective AI-assisted workflow and potentially help the team adopt it
• Ability to explain how AI-assisted development affects project timelines and cost

Growth to Frontend Team Lead
As you grow into the Lead role, your responsibilities will gradually include:

• Direct client communication and calls with CTOs / founders
• Presenting and defending architectural decisions, scope, and estimates
• Translating business requirements into technical solutions and explaining technical risks in business language
• Mentoring and onboarding developers
• Establishing engineering standards and code review guidelines
• Technical coordination between our team and the client’s engineers
• Participation in technical interviews and candidate evaluation
• Project estimation and occasional presale support
   

Nice to have:

• Web3: WalletConnect, ethers.js / viem, wallets, smart contracts
• Telegram Mini Apps
• Node.js / Express / MongoDB
• Storybook, design systems, UI kits
• Previous Team Lead / Tech Lead experience
• Presale and project estimation experience

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.
