Senior Software Engineer - Frontend

Role Description

We’re looking for frontend engineers who are excited about:

• Building data-intensive products that developers use for hours every day
• Making complex, multi-module workflows feel simple and intuitive
• Pushing React performance so the UI never gets in the way—especially during a production incident

This role goes beyond implementing screens from specifications. You’ll own meaningful parts of the product experience from problem definition to production.

You will:

• Design and build complex workflows across dashboards, traces, logs, metrics, alerts, and infrastructure monitoring
• Own large frontend features and systems end-to-end
• Turn technically complex observability concepts into clear, intuitive experiences
• Architect for performance using techniques such as virtualization, progressive loading, smart caching, and selective rendering
• Profile and improve slow interactions, large visualizations, and data-heavy views
• Contribute to our frontend architecture, design system, and engineering standards
• Work closely with design, product, founders, and backend engineers
• Speak with users and ship improvements that help engineers investigate incidents faster
• Help other engineers make better frontend and product decisions

Qualifications

• You have strong experience building production applications with React and TypeScript
• You think in systems and user journeys—not just individual screens
• You care about product experience as much as code quality
• You have worked on complex, data-heavy, or highly interactive applications
• You understand React rendering behaviour and know how to find performance bottlenecks
• You are comfortable using browser profiling and debugging tools
• You can make thoughtful trade-offs between performance, maintainability, and delivery speed
• You take ownership and can move work forward without detailed instructions
• You communicate clearly and work well across engineering, design, and product
• Experience with observability is helpful, but not required. Curiosity and the ability to understand complex technical domains matter more.

Requirements

• Rendering dashboards containing many charts and large datasets without slowing down the browser
• Building fast and intuitive experiences for exploring millions of logs or traces
• Visualizing complex distributed traces and service relationships
• Creating consistent interactions across multiple product modules
• Improving loading, filtering, navigation, and debugging workflows during live incidents
• Evolving a large frontend codebase while the product and team continue to grow

Benefits

• We are remote-first and have no offices. Work from wherever you do your best work.
• We are a small, experienced team, so individual contributions have visible impact.
• Engineers have meaningful ownership over both technical decisions and the product experience.
• We move quickly, talk directly with users, and continuously improve what we ship.
• Observability is a large and growing market, but more importantly, it is a space full of difficult product and engineering problems.
