Job Description:

Yournextchallenge

JoinCobee byPluxee as aSeniorProductEngineer and become a key contributor to our mission of revolutionizing employee compensation.You'llown 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.

DomainContext

The domainyou'lljoin depends on which squadyou'reassigned to.

Benefits - Own the domain that defines what benefits an employee can access, under what conditions, with what limits, and in what markets. Benefitsisn'ta simple CRUD layer -it'sa 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 coversthe 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 clientcompaniesentity itself, the core record that everything else in the system hangsoff 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.
