Offer description

Hi, Polcode here!

We’re a global, people-first software house matching ambitious developers with challenging projects. Our team of over 100 professionals helps build and improve digital businesses, software platforms, eCommerce stores, websites, apps, and everything in between. And they’re good at it.

We are currently seeking a highly experienced Senior/Lead Backend Developer who enjoys real ownership and can work independently in a greenfield environment. A full-stack orientation is strongly preferred, especially if you’re comfortable supporting end-to-end flows and collaborating closely with a React-based frontend.

You’ll join a compact, dedicated team building a brand-new ticket sales platform for a large Polish event agency. This is a full-time and fully remote engagement starting in January, planned for 4–6 months, with a strong chance of continuing long-term depending on the client’s roadmap.

Why this project is worth your attention:

• 100% greenfield - you’ll help shape architecture and key decisions from day one
• Real autonomy & decision-making - we want your ideas, not just execution
• End-to-end product scope with visible business impact
• Support from experienced Polcode’s team: PDM, DevOps, QA, FE developer, plus CTO & Solutions Architect when needed.
• Strong potential for long-term continuation - further product growth, scaling, new feature development and ongoing maintenance.

Perks of being a #Polcoder:

• Multisport card, private medical care, life insurance, and meaningful gifts to celebrate important days
• All the necessary equipment for comfortable work
• Professional onboarding process
• We respect your private life - no overtime, no weekend jobs, work-life balance only, promise!
• Work at times that suit your daily rhythm, from the place of your choice
• Your work is appreciated - we believe in the power of feedback, as well as the one you give us.

TL;DR

• 100% remote work
• 0% nonsense

We strongly believe that putting people first makes our work better.

We encourage you to grow your career, contribute to open source, and follow your passion. We wanna do great things with you! 💜
