Product Engineer (Flutter)

Ho Chi Minh - Viet Nam


Product

  • Flutter

Own products and features from beginning to end - originate ideas, understand the strategy and goals behind them, ship to production with real users, iterate on feedback, and stay responsible for their ongoing success. Scope features and projects, including writing handover / technical design documents (as built) - the person who built a feature is the best person to document it. Improve application performance - ship technical improvements that make the product faster, more stable, and ready to scale. Sweat the UI and interaction details - crafting a clean, pleasant experience is a daily habit, not an afterthought. Improve how we work, not just what we build: refine development processes, drive improvements in code quality and engineering best practices - and hold a zero-bug standard: bugs get fixed promptly, not stockpiled in a backlog. Work closely with designers to craft thoughtful UX/UI - ship and own the basic experience using the design system, deciding when to bring in design to polish - and collaborate with the Customer Success team to learn how the product is actually being used. Bring a tester's mindset - testing is part of building, not someone else's job. You own the quality of what you ship and stand behind it.
