You'll own features end-to-end — backend, frontend, and the AI-assisted workflows that let one engineer move fluidly across the stack — inside one of our core domains.
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.
Leaders— covers the employee-facing mobile and web experience within the Cobee platform, managing personal data, benefit visibility, and privacy compliance (GDPR/LPD). A domain where company-level configuration, data integrity, and cross-region consistency matter as much as UX.

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. Understand the complexities of existing systems and evolve them into scalable, event-driven architectures to meet future integral product requirements.
