Mid-level Front-End Developer eComm agency

More about us and our projects [click]

Hey!

We’re looking for a talented Front-End Developer to help us build beautiful e-commerce stores for some of the world’s best DTC brands.

If you want to level up your front-end skills, work in a modern tech stack, and be part of a senior team - this role is for you.

We also take growth seriously. We have four clearly defined engineering levels (SE I, SE II, Senior SE I, Senior SE II), each with explicit expectations. You’ll always know where you stand and what’s required to reach the next level.

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

Skills we're looking for

• 2+ years of experience in Javascript, HTML and CSS

• Experience in building high-quality, responsive layouts

• Eye for the design detail and caring about user experience

• Awareness of web performance best practices (Core Web Vitals), developing for accessibility and SEO

• Interpreting and working with third-party APIs

• Communicative in both verbal and written English

• Fluency in Polish language

What makes a strong fit

• You think in trade-offs - when you choose an approach, you can explain why and what you're giving up

• You own your work end-to-end: from unclear brief to deployed feature, including the parts nobody explicitly asked you to handle

• When something isn't going to plan, you raise it early - and you bring a proposal, not just the problem

• You can explain a technical decision clearly to a developer and a PM in the same conversation

Nice to have:

• Experience in e-commerce (any platform)

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
