The Role
We are looking for a Senior Flutter Developer to own the mobile experience of our digital retail ecosystem. This is not a standard "CRUD" app; it is a mission-critical tool that must work 24/7 in high-pressure retail environments. You will use a Hybrid "Add-to-App" model, embedding Flutter modules into native Android/iOS shells to access deep hardware APIs for payment terminals (Smart POS). You will be responsible for ensuring a "Zero-Latency" checkout experience and a robust offline-first sync engine.
What You'll Do
- Development: Implement Flutter modules using the Add-to-App model to allow seamless communication between Dart and Native SDKs.
- Backend Integration: Work closely with the backend team to integrate with the Java-based microservices architecture via a REST API.
- Hardware Integration: Implement and manage integrations with Smart POS payment terminals, receipt printers, and barcode scanners within the native Android/iOS shells.
- App Features: Develop modules for a POS Sales & Billing, B2B Marketplace, AI companion, Banking, and Inventory Management. You will be responsible for building the dynamic UI that surfaces real-time, AI-driven suggestions and insights to the user.
- High-Utility UI: Build pixel-perfect interfaces from Figma, optimized for large tap targets and rapid multi-tasking in busy convenience stores.
- Offline Capabilities: Design and implement a robust local storage (SQLite) solution to ensure the app functions seamlessly with intermittent internet connectivity.
- Code Quality: Establish and enforce best practices, conduct code reviews, and maintain high-quality standards for the entire mobile codebase.
- Collaboration: Work closely with the Product Manager and Backend team to align on features, timelines, and technical requirements.
- Performance and Reliability: Obsess over app performance, ensuring a fast, fluid, and crash-free user experience, which is critical in a retail transaction environment.
What We're Looking For
- 5+ years of mobile development experience, with at least 3+ years of deep, hands-on experience with Flutter.
- Proven experience with Flutter’s Add-to-App feature and native development (Kotlin/Android or Swift/iOS)
- Experience integrating with external hardware (payment terminals, printers) via native SDKs.
- Strong understanding of state management, API integration (REST), and local database (SQLite) implementation in a mobile context.
- Organized: Ability to plan and take ownership of tasks, deliver quality work, and meet deadlines independently.
- Testing: Experience with Flutter Integration Tests to ensure hardware-sensitive flows don't break.
- Communication: Effective communication skills with team members and stakeholders, showcasing your work confidently.
- Languages: Fluent in English to seamlessly integrate with our international team and clientele. Since the product is focused on the Latin American market, being Spanish-speaking is a significant advantage.
What To Expect
- Flexibility - We have standard 40-hour work weeks. While our agency working hours are from 9 am to 7 pm CET, you’ll have the freedom to work flexible hours and maintain a healthy work-life balance. Just make sure the majority of your working hours fall within that time frame.
- Remote work & Tooling - We operate as a fully remote team. We utilize HubStaff for time tracking and work transparency. We value trust and output, and these tools help us streamline administrative overhead.
- Culture - We value collaboration, openness, a willingness to learn, lead, and a curious nature. Our approach encourages mistakes as long as we are willing to learn from them, fostering a culture where growth comes from understanding and overcoming challenges.
- Autonomy and responsibility – You’ll be trusted to get things done efficiently and effectively.
Hiring Process
- Application review - We’ll review your experience, background, and overall fit for the role.
- Video Call with HR - Initial conversation about fit, availability, and expectations
- Second interview with Leadership - If there is a strong match after the first conversation, we’ll invite you to a second interview with the Leadership team. This discussion will focus primarily on cultural fit, ownership, communication, and the way you approach collaboration and problem-solving. We may also revisit a few technical topics if anything needs additional clarification.
