## Job Description
Hey! We're looking for an experienced Senior Front-End Developer (Project Lead) to join our team at Commerce-UI.
If you're excited about working with strong eCommerce brands, taking real ownership, and shaping how things are built and not just executing, this might be a great fit.
This isn't a typical dev job. You'll be the technical lead on real production projects, solving real business problems through technology. From the first line of code to launch, you'll have end-to-end ownership, defining how we build, mentoring others, and ensuring our clients' visions come to life beautifully and reliably.
You'll work alongside other highly skilled and dedicated developers, designers, and project managers. People who care deeply about quality, craft, and collaboration. We're a small, senior team, so every person has a big impact.

What we do
Since 2019, we've worked with brands like Lady Gaga, Carhartt WIP, Magda Butrym and Rolex, and collaborated with designers from Pentagram, ex-Tesla, and ex-Apple.
We're focused entirely on eCommerce, and our goal is simple: to be one of the best eCommerce tech teams in the world.

About the Role
What you'll do

Lead front-end development for top-tier eCommerce projects
Collaborate closely with designers, other devs, PMs, and clients to translate ideas into high-performing storefronts
Write clean, thoughtful, and production-ready code
Make key architectural and technical decisions
Ensure delivery excellence and lead communication with clients when needed
Continuously push for better engineering practices and scalable solutions
Contribute to internal standards, tooling, and workflows
Mentor other developers and promote best practices

Who you are

A senior engineer with strong experience in React / Next.js / React-Router or any other isomorphic JS framework
You've led production projects or small teams before. You know how to ship
You value pragmatic engineering. You focus on what works and scales, not over-engineering
You enjoy working in small, dedicated teams and taking ownership
You care about both the craft and the outcome. Elegant solutions that drives real business results
Design-awareness. You care about polish, UX, and performance
Comfortable managing multiple shifting priorities with support from PM and tech leads
Bonus: experience with headless commerce (Shopify, Commerce Layer, etc.)

What We're Looking For

5+ years of experience with JavaScript/TypeScript, HTML, CSS, and modern frameworks (ideally Remix or Next.js)
Strong communication skills - you're confident discussing trade-offs with clients and teammates
Fluent English (for client work) and at least B2 Polish
Design-awareness - you care about polish, UX, and performance
Comfortable managing multiple shifting priorities with support from PM and tech leads
