Frontend Developer in Barcelona

About The Left Bit 

We're a mobile and web software studio based in Barcelona. Founded by ex-Wallapop builders, our team brings together people who've seen what good product engineering looks like and care about doing it right.

We work with a select group of clients on long-term partnerships. We don't chase quick deliveries. We build things that last.

Our team is around 10 people, and we are seeking a new Frontend Developer.

The Role

We're looking for a Frontend Developer with 2-3 years of experience to join our web team. You'll work across client projects - real products used by real people - and be expected to take ownership from day one.

If you have a Full Stack mindset (or are curious about the backend), even better. Our stack is React + Django, and we like engineers who can move fluidly across it. 

What you'll do 🛠️

• Build and maintain frontend features for client products using React
• Collaborate directly with clients - understanding their needs, communicating clearly, and knowing what to say (and what not to)
• Take ownership when problems arise: diagnose, prioritize, and resolve without waiting to be told
• Think beyond the ticket - consider the long-term impact of what you build
• Work in a small, focused web team with daily standups and real autonomy

What we're looking for 🔍

• 2+ years of experience in frontend development (React)
• Comfortable with or curious about backend work (Django/Python)
• Familiarity with PostgreSQL and GitHub Actions
• Strong English - you'll be working with international clients
• A genuine sense of ownership: you spot a problem, you don't wait around
• Good communicator - with the team and with clients
• Curious and hungry to keep learning, both technically and professionally

Nice to have 

• Experience with Fly.io or similar deployment platforms
• Full stack experience (Django)

About the hiring process 📋

1. Cultural fit call - we want to know your motivations and values, how you think, what you've built 
2. Tech challenge (~2-3 hours) - a real problem, not a puzzle. We care about how you approach it, not whether you hit every point 
3. Technical interview, to discuss challenge, among other things 
4. Offer 🎉

What's in it for you ✨

• Hybrid flexibility (ideally 2-3 days in our Barcelona office in Poblenou) 
• All tooling covered by the company 
• A team that values craft, not just delivery 
• Real client exposure and communication from day one 
• A culture where your curiosity and initiative actually matter
