Lead Full-Stack Engineer — Mobile

Lead Full-Stack Engineer — Mobile

Company: Varicon
Location: Kathmandu, Nepal — Hybrid
Employment Type: Full-time
Application Deadline: September 20
Apply to: hr@varicon.com.au

About the Role

As Lead Full-Stack Engineer — Mobile, you'll be the technical owner of our Flutter mobile applications and the go-to engineer for mobile architecture, delivery, and complex technical problems. You'll lead development of our field-worker and admin/employee apps, working across Flutter/Dart and Python (Django/DRF) when backend changes are required. This is a hands-on technical leadership role — not a people-management role — with significant time spent writing code, reviewing PRs, and solving hard technical problems.

What You'll Do

• Own the architecture and technical direction of Varicon's Flutter mobile applications

• Design and maintain robust offline-first workflows — local storage, background sync, conflict resolution, and reliability under poor connectivity

• Write and ship production Flutter/Dart code as a core part of the role; work full-stack when required (Django/DRF)

• Own the mobile testing strategy (unit, widget, integration, E2E) and drive up code quality

• Own mobile release reliability — CI/CD, App Store/Google Play releases, OTA updates (e.g. Shorebird)

• Monitor and resolve production issues using tools like Crashlytics and Sentry, driving root-cause fixes

• Mentor mobile and full-stack engineers through pairing, reviews, and technical coaching

• Partner closely with Product, Design, and Web/Backend Engineering to deliver features end-to-end

• Use AI-assisted tools (Cursor, Claude Code, GitHub Copilot) as part of daily engineering workflow

What We're Looking For

Must-Haves

• 6-8+ years of professional software engineering experience, with significant hands-on mobile development experience

• Strong, production-level experience with Flutter and Dart

• Experience leading technical delivery for a mobile product or significant mobile domain

• Strong understanding of Flutter state management (BLoC, Riverpod, Provider, or equivalent)

• Experience with offline-first applications and data synchronisation

• Experience with native iOS/Android build and release processes, including App Store and Google Play submission

• Strong testing background across unit, widget, integration, and E2E levels

• Comfortable working with Python and Django/DRF (required)

• Experience designing and consuming REST APIs; understanding of relational databases and asynchronous processing

• Proven hands-on use of AI coding tools as part of a normal workflow

Nice-to-Haves

• FastAPI experience

• Experience with OTA update tools such as Shorebird

• AWS experience

• Experience with CI/CD and mobile release automation tooling

Experience Level

6-8+ years of professional software engineering experience, with deep, hands-on ownership of a production Flutter/mobile codebase, plus solid working knowledge of Django/DRF for backend work.

What Varicon Offers

• Competitive salary and performance-based bonuses

• Festive Bonus

• Access to Cursor, Claude Code, and AI-powered code reviews

• Significant ownership of mobile technical direction

• Opportunity to solve real-world offline-first, sync, and field-connectivity challenges

• A collaborative, learning-focused engineering environment
