We're hiring a Founding Full-Stack Engineer (Flutter and Java) to build and ship the core product experiences that customers actually use at Grand. This is a hands-on individual contributor role for someone who enjoys owning problems end-to-end. You'll design, build, and ship features across frontend and backend, targeting mobile and web, and using AI tools by default to move faster without sacrificing quality. We work in Java on the backend, but we're hiring for depth, not language. If you've built and operated production backends — in Go, Kotlin, Python, or another modern stack — and are excited to write Java, we want to talk. This is a product-focused engineering role, and at Grand you are your own product manager. You'll work alongside founders, designers, AI engineers, and other product engineers — shaping what gets built, not just how. Your primary responsibility is shipping end-to-end product functionality that's reliable, well-designed, and production-ready. This is a 0→1 environment, where you help define how Grand feels, behaves, and earns trust from day one. ## What You’ll Do
Design, build, and ship Flutter applications for mobile (iOS, Android) and web
Implement product features using established design systems and component libraries
Contribute thoughtfully to reusable frontend components where needed
Account for mobile release cycles, performance, offline behaviour, and partial failure
Integrate platform services and AI capabilities into user-facing workflows
Make product decisions on what to build and how, in collaboration with founders and designers
Write Java services and APIs on AWS to power your frontend features
Design APIs and data models that operate reliably within a distributed backend, with a security-first mindset
Use AI-assisted development tools to accelerate coding, testing, and refactoring
Own features through their full lifecycle, from idea → production → iteration
Must Have
Shipped at least one Flutter app to production on the App Store or Play Store, ideally with end-to-end ownership
Strong Flutter experience including state management, platform channels, and production debugging
Strong backend experience in real production systems — Java preferred, but comparable depth in Go, Kotlin, Python, or another modern backend stack is welcome (you must be excited to work in Java)
Experience designing APIs, modelling data, and reasoning about distributed concerns (latency, retries, idempotency, failure handling)
Experience shipping and operating software in AWS-based production environments
Familiarity with CI/CD workflows across mobile and backend
Experience working in startup or 0→1 environments
Security, data-protection, and compliance awareness when building production systems
AI-first mindset, using modern tools to increase velocity responsibly
Nice to Have
Experience building products in fintech, payments, credit, identity, KYB, or other regulated/financial environments
Advanced Flutter: web alongside mobile, deep linking, push notifications, in-app review prompts, and frontend testing
Real-time features in production (WebSockets, server-sent events, live updates)
GraphQL in production
Direct Java experience, including event-driven or distributed architectures
Experience integrating with AI/ML systems in cloud-native environments
Salary and Benefits
Excellent Salary: Competitive and reflective of impact and responsibility
Equity: Meaningful ownership in a long-term company
Hybrid Work: At least 3 days in our Dublin office, with extended remote on request — outcomes matter more than optics
Health Insurance & Pension: Comprehensive cover
Holidays: Generous holiday allowance
Equipment: High-end spec laptop and setup of your choice
Who You Are
You want to build a company, not just code at one. You're a product-minded engineer with a startup mindset, comfortable operating in a 0→1 environment, making progress with imperfect information and taking responsibility for outcomes. You have a bias toward shipping real value, not ceremony or over-engineering. You enjoy building things people actually use and rely on, especially on mobile and web. You care about how a product feels — the polish, the responsiveness, the small details — and you understand how clients, APIs, and cloud systems interact under real-world conditions. You care about reliability, performance, and clarity across the stack, not just getting something working once. You're a clear communicator who can reason about trade-offs and constraints with founders, designers, and other engineers. You use AI tools to move faster, but you understand the code you ship and stand behind it. You thrive in ambiguity, take pride in owning problems end-to-end, and build software that earns trust. You're based in Dublin, or in easy commuting distance (or ready to be), and ready to help build a product from the inside out. If this sounds like you, let’s talk.
