About the Position

As a Senior Frontend Engineer at Landbot, you’ll play a key role in shaping how users interact with our product. This is not just about writing code, it’s about crafting experiences, building systems that scale, and helping evolve our platform to meet tomorrow’s challenges.

Write clean, maintainable, and testable code, with simplicity and quality as guiding principles.

Collaborate closely with Product and Design teams to deliver exceptional user experiences.

Act as a go-to expert in testing, driving a quality-first mindset across the frontend.

Build reusable UI components and design systems adaptable to different contexts : web apps, browser extensions, desktop, and mobile applications.

Provide technical leadership in design discussions and decisions that impact multiple teams or the company as a whole.

Make thoughtful trade-offs between short-term delivery needs and long-term technical health.

Document your work rigorously (ADRs, RFCs, postmortems) and share learnings across the org.

Stay ahead of industry best practices and bring fresh, practical ideas into the team.

Lead by example : mentor teammates, give constructive feedback, and raise the engineering bar.

This role blends hands-on engineering with technical leadership : you’ll be a go-to reference for frontend excellence and help elevate the entire team.

How You Will Make a Difference

You bring a Product-Engineering mindset : solving user problems and improving the product is your ultimate goal.

Stay close to the user : deeply understand who they are, their problems, frustrations, and behaviors. Great engineers don’t just write code — they connect technology to real people, ensuring our work creates meaningful impact in the market and in users’ lives.

You are your own first user : you live and breathe the product, ensuring it meets your own high standards of quality.

You constantly ask : “Is this truly valuable? Will this feature improve our users’ lives, reduce platform costs, or unlock impact?”

You see user problems as shared problems, not “someone else’s problem.”

You act with autonomy and accountability, ready to have an impact at both the product and team level.

You help create a culture of excellence, continuous learning, and ownership.

Strong expertise in TypeScript, React, Redux, and modern frontend ecosystems

Deep experience with testing at all levels : unit, integration, functional, and E2E.

Strong software engineering fundamentals and ability to simplify complex problems.

Experience shipping to production frequently (we deploy multiple times per day).

Familiarity with performance optimization and scaling frontend applications.

Passion for feedback, learning, and mentoring others to raise engineering standards.

Strong collaboration mindset, you value product, design, and cross-team partnerships.

Bonus : Exposure to AI-driven interfaces or curiosity about designing UX for AI-powered features.
