More about us and our projects [click]

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

What it’s really like to work here

At Commerce-UI, we trust each other’s judgment and take pride in our craft. Everyone here owns their work - not because someone expects it, but because we care about what we build and the people we build it with.

We believe in high standards and flexibility, and we back that with real autonomy from day one. You’ll quickly see how we operate: fast, focused, and with a lot of trust that everyone knows what they’re doing.

We don’t rely on layers of management or rigid playbooks. Instead, we collaborate closely, share context openly, and help each other grow. Things move quickly, but that’s part of the fun - it’s how we learn, adapt, and ship meaningful products for iconic brands.

If you value ownership, clarity, and a team that believes in mutual trust and high craftsmanship, you’ll feel right at home with us.

Why you’ll love working here

• Small, senior, passionate team - no bureaucracy, real impact

• Work on ambitious, design-led projects for global brands

• Freedom to shape how we build things

• Competitive pay and flexible, remote-friendly culture

Our Tech stack

• Shopify Hydrogen (React-Router 7/Remix) or Next.js

• Oxygen, Vercel, Cloudlfare

• Shopify Liquid/Online Store 2.0

• Typescript (always)

• CSS, Sass, CSS Modules, Stitches, Vanilla extract

Toolkit
