Job description

About The Position

Coralogix is a modern, full-stack observability platform transforming how businesses process and understand their data. Our unique architecture powers in-stream analytics without reliance on expensive indexing or hot storage. We specialize in comprehensive monitoring of logs, metrics, trace and security events with features such as APM, RUM, SIEM, Kubernetes monitoring and more, all enhancing operational efficiency and reducing observability spend by up to 70%.

About Our Squad

We're building some of the most important user experiences in Coralogix.

Our team owns the frontend experience for products like Explore, APM, and RUM - interfaces engineers rely on every day to investigate, debug, and understand their systems.

Although we're frontend-focused, we're a full-stack product team. We own features end-to-end, from product discussions and UX decisions to architecture, implementation, backend integrations, and production.

Engineers on our team don't just implement designs - they help define the product, challenge assumptions, make technical decisions, and shape how users experience Coralogix.

We're looking for a Senior Frontend Engineer who is a builder at heart: someone who can own complex problems, navigate ambiguity, make strong technical and product decisions, and raise the engineering bar around them.

100% Remote. Candidates must be legally based in a European country.

• Is comfortable with ambiguity and challenges ideas constructively.
