Permanent Regular Job Description: Senior Product Engineer and become a key contributor to our mission of revolutionizing employee compensation.
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.
A high-performance team dedicated to resilient, mission-critical systems where transactional precision, idempotency, and fault tolerance are at the heart of everything. 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). A domain where company-level configuration, data integrity,



and cross-region consistency matter as much as UX.
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.
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 general product requirements.
You will champion comprehensive automated testing (unit, integration, and e2e) and run advanced load and performance simulations to guarantee rock-solid stability
Share your expertise through deep code reviews, mentoring junior engineers, and documenting engineering standards that elevate the entire squad.
