Senior Frontend Engineer

As a Senior Frontend Engineer, you’ll work at the intersection of speed, design, and experimentation. You’ll build user-facing features using React and related technologies, supporting our product growth efforts with a strong focus on team activation, onboarding, and conversion to paid plans.

You’ll be involved not just in development, but also in generating lightweight design proposals and suggesting improvements to ship experiments faster, always keeping the hypothesis in focus.

Your main responsibilities will include:

• Leading and building rapid product experiments across Track and Suite
• Translating hypotheses into UI solutions in collaboration with Product Designers
• Optimizing frontend performance for speed and usability
• Collaborating with cross-functional teams to ship end-to-end experiments
• Maintaining high code quality and conducting code reviews
• Proactively helping reduce experiment scope and improve implementation speed through pragmatic design and technical suggestions

Does this sound like you?

You’re a hands-on senior engineer who can bring structure, speed, and creative thinking into experimentation. You’re analytical, pragmatic, and excited to work closely with Product to validate hypotheses and drive measurable impact.

We’re looking for someone who:

• Has strong experience with JavaScript, React, and preferably Redux (and a side-effect library like Redux-Saga)
• Is comfortable working with TypeScript, HTML, CSS and modern frontend stacks
• Has experience leading development projects and collaborating cross-functionally
• Understands experimentation and can balance technical debt vs speed
• Has experience designing or co-creating simple UI/UX flows (no design tools required)
• Is proactive, detail-aware (but not obsessed with pixel-perfection), and able to simplify complexity
• Communicates clearly and works well in a remote, async-first team
• Is eager to mentor junior engineers and contribute to the engineering culture
• Has excellent English communication skills
