• Drive technical excellence by implementing Test-Driven Development (TDD) and comprehensive testing suites to maintain a robust codebase.

• Collaborate on AI-driven features, integrating intelligent workflows into the frontend to enhance the customer journey.

• Maintain design consistency by leveraging Tailwind CSS and shadcn/ui to build beautiful, functional interfaces.

• Optimize full-stack efficiency by collaborating on Node.js services and RESTful API integrations.

• Lead by example in code quality, conducting peer reviews that foster a culture of clean, maintainable code.

Qualifications

• Cloud & CI/CD: Knowledge of Google Cloud Platform (GCP) infrastructure and hands-on experience with CI/CD pipelines.

Hybrid Modality

We focus on trust and performance. We are implementing a Two phased approach for our Hybrid Modality:

Phase 1: While the teams are establishing ways of working, building trust, and developing their rhythm, we ask that you’re present in the office Three days a week. In-person proximity is key to accelerating the forming stage.

Phase 2: Once teams are performing, we move to a more relaxed hybrid model. We ask for a minimum of one day per week in the office, centred around critical ceremonies such as sprint planning, reviews, and retrospectives.
