We're looking for a Senior Software Development Engineer (Flutter / Backend) to join our core engineering team working on mobile-first, backend-driven products for leading hospitality brands across the region.

This is a cross-functional role where you'll develop production-grade Flutter apps and architect powerful backend systems that drive loyalty programs, ordering workflows, discount engines, and more.

You'll be part of a high-impact product squad with close collaboration across engineering, design, and product.

Important: This role requires strong backend experience (Node. js, GCP, GraphQL).

Flutter is essential, but backend engineering is a deal-breaker.

What You'll Do :

- Build and maintain high-quality Flutter-based mobile apps used by QSR brands and venues across APAC.

- Architect and develop scalable backend services using Node.js (Nest.js, Express.js) and TypeScript.

- Create, maintain, and optimize GraphQL (Apollo) and REST APIs for mobile clients.

- Design efficient relational data models using PostgreSQL and caching strategies via Redis.

- Deploy, monitor, and maintain services on Google Cloud Platform (GCP) using CI/CD and infrastructure best practices.

- Write clean, maintainable, testable code - and set the bar for engineering excellence through code reviews and refactoring.

- Work closely with product managers, designers, and other engineers to define technical specs, scope delivery, and ensure product success.

- Contribute to the adoption of AI-powered tooling to accelerate development and enhance system intelligence.

Qualifications :

- 5+ years of software development experience, with a strong focus on backend systems.

- 3+ years of experience developing apps in Flutter (Dart).

Hands-on experience with :

- Node.js, Nest.js, Express.js (TypeScript).

- PostgreSQL (data modelling) and Redis.

- GraphQL (Apollo) and REST API design.

- Google Cloud Platform (GCP) or equivalent cloud platforms.

- Proven ability to deliver backend-heavy mobile applications in production environments.

- Strong debugging and performance optimization skills.

- Excellent communication and cross-functional collaboration skills.

- Comfortable working full-time during AEST hours (Australian business hours).

Good to Have :

- Experience in hospitality, retail, or transaction-heavy domains.

- Familiarity with CI/CD pipelines, monitoring, and observability tools (e., Stackdriver, Sentry, Datadog).

- Exposure to AI/ML tools, prompt engineering, or automation frameworks.

- Experience integrating with third-party platforms (POS systems, payments, loyalty, CRM).

- Contributions to open source or participation in developer communities.

- Experience working in remote-first teams across region
