Job description

Description

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.

Responsibilities

• Own complex product features and technical initiatives from idea to production.
• Design and build intuitive, high-performance user experiences using Angular.
• Drive frontend architecture and technical decisions with scalability, maintainability, performance, and user experience in mind.
• Collaborate closely with Product, Design, Backend, and other engineers to shape solutions - not just implement requirements.
• Translate complex technical concepts and large amounts of data into simple, elegant user experiences.
• Proactively identify opportunities to improve the product, architecture, and engineering practices.
• Write clean, well-tested, production-ready code.
• Review code, mentor engineers, and help raise the technical level of the team.
• Use AI-assisted development effectively to accelerate delivery while maintaining high engineering standards.

We’re Looking For Someone Who

• Loves building products, not just writing code.
• Takes end-to-end ownership and drives complex work to completion.
• Has strong technical judgment and makes thoughtful architectural tradeoffs.
• Cares deeply about UI/UX, performance, and product quality.
• Is comfortable with ambiguity and challenges ideas constructively.
• Works effectively across Product, Design, Backend, and Engineering.
• Helps other engineers grow and continuously raises the bar around them.

Requirements

• 7+ years of professional frontend development experience, including ownership of complex production applications.
• Strong experience with a major frontend framework (Angular, React, or Vue).
• Strong proficiency in TypeScript, JavaScript, HTML and CSS/SCSS.
• Experience designing scalable frontend architectures and building complex, data-intensive applications.
• Strong understanding of browser fundamentals, frontend performance, and modern web development practices.
• Strong understanding of UI/UX principles and attention to detail.
• Experience with APIs, state management, testing, and modern frontend development workflows.
• Strong problem-solving skills and ability to independently lead complex technical work.
• Strong communication skills and experience working in cross-functional teams.

Nice to Have

• Experience with Angular and large-scale Angular applications.
• Experience with monorepos and tools such as Nx.
• Experience with observability platforms, developer tools, or large-scale SaaS products.
• Experience with frontend performance optimization and data-intensive UIs.
• Experience with cloud platforms such as AWS or GCP.
• Familiarity with backend technologies and distributed systems.
• Experience with AI-assisted development tools and workflows.

Cultural Fit

We’re seeking candidates who are hungry, humble, and smart. Coralogix fosters a culture of innovation and continuous learning, where team members are encouraged to challenge the status quo and contribute to our shared mission. If you thrive in dynamic environments and are eager to shape the future of observability solutions, we’d love to hear from you.

Coralogix is an equal opportunity employer and encourages applicants from all backgrounds to apply.
