About Us 

We are a technology company specializing in software development, digital transformation, and offshore development services for clients in Japan, Australia, Singapore, and other global markets. Beyond outsourcing, we build our own products — including Deligo (Logistics & Delivery Platform) and Delippy (E-Commerce Marketplace) — serving thousands of real users every day. We are expanding our engineering team and looking for a Senior Flutter Developer who can drive mobile excellence across both client projects and in-house products.

Why This Role Is Exciting:

• Ship code used by thousands of real users — on Deligo and Delippy immediately
• Work with international clients — from Japan, Australia, Singapore
• Shape mobile architecture — not just implement tickets
• Clear career path — Senior → Tech Lead → Solution Architect
• Best of both worlds — outsourcing exposure + product ownership

Responsibilities

• Lead the design and development of Flutter modules for Deligo, Delippy, and international client projects.
• Mentor and conduct code reviews for junior/mid Flutter developers — raise the bar for the whole team.
• Make architecture decisions for mobile: state management approach, folder structure, performance strategy.
• Drive the full SDLC: from requirement analysis and UI/UX collaboration to deployment and post-launch monitoring.
• Integrate RESTful APIs, third-party SDKs (payment gateways, maps, real-time chat, push notifications).
• Optimize app performance, security, and user experience for large-scale applications.
• Own the release pipeline to Google Play Store and Apple App Store, including CI/CD processes.
• Troubleshoot and resolve issues across development, staging, and production environments.
• Collaborate closely with Product Owners, Backend Developers, UI/UX Designers, QA Engineers, and DevOps.
• Participate actively in Agile/Scrum sprints (2-week cycles), planning, and retrospectives.
