Benefits   isn't   a simple CRUD layer —   it's   a rich domain with multi-tenant configurations, eligibility rules that vary by company and country, tax compliance requirements, and real-time state that must always be consistent. Covers areas like health insurance, pensions, custom benefits, food and transport, childcare, training, and renting.   Payments   — Build the engine that moves money globally. A high-performance team dedicated to resilient, mission-critical systems where transactional precision, idempotency, and fault tolerance are at the heart of everything. Involves evolving distributed, event-driven architectures at high transaction volume.   Leaders   — The Leaders domain covers   the employee -facing mobile and web experience within the Cobee platform, managing personal data, benefit visibility, and privacy compliance (GDPR/LPD). The domain shares boundaries with Payments (owning employee-specific card logic and mobile flows) and Benefits (storing accumulation activation decisions while Benefits executes the end-of-cycle operations).     Managers App   Owns the HR admin experience, the tools client-company administrators use to manage their organization on the platform, and the client   companies   entity itself, the core record that everything else in the system hangs   off of . Spans self-onboarding flows, multi-region and multi-market rollout, and the operational reliability of the admin-facing product. A domain where company-level configuration, data integrity, and cross-region consistency matter as much as UX.   🚀   Key   Responsibilities   What   You’ll   Do   Own Features End-to-End : Take a feature from domain design through backend services to the UI that ships it, and the observability that tells you   it's   working.   Design for Resilience at Scale : Build and   optimize   robust software capable of handling high-volume traffic while ensuring data consistency and system reliability, evolving existing systems into scalable, event-driven architectures as product requirements grow.   Evolve   Distributed   Architectures :   Understand   the   complexities   of   existing   systems   and   evolve   them   into   scalable ,   event-driven   architectures   to   meet   future global   product   requirements .   Mission-Critical Precision:   When dealing with benefits and money movements, accuracy is essential.
