We’re looking for a Junior Frontend Developer to help build and improve applications for our US clients - from early-stage MVPs to established products in FinTech, SportsTech, MedTech, and other industries.

We’re building a team of engineers who can contribute across the application while developing deep expertise in frontend or backend engineering. In this role, frontend is your primary discipline, and you’ll broaden your contribution across the stack as your experience grows. You’ll build this foundation with support from experienced teammates.

AI-assisted development is part of this role. You’ll learn to use coding assistants for exploration, implementation, and debugging, while building the skills to understand their suggestions, check the results, and recognise when to ask for help.

  • Rate: PLN 6.000 - 9.000 + VAT / month (B2B); PLN 6.000 - 7.400 gross / month (UZL)
  • Contract: B2B/UZL, no-service days, 100% remote (or hybrid/onsite-as you prefer), Polish time zone, Europe-based, flexible hours, full-time position, long-term contract
  • Perks and Benefits: 3,000 PLN annual training budget, Multisport, Luxmed, Cafeteria Platform, Tech-talks, Learning sessions, and more

  • Your future tasks:

  • Develop application features and fix bugs, working on clearly defined tasks with support from experienced developers
  • Implement responsive interfaces with attention to design details, accessibility, and user experience
  • Connect interfaces to APIs and learn how the frontend, backend, and data work together
  • Gradually contribute to backend tasks, such as small API changes or straightforward business logic, with guidance and code review
  • Use AI coding assistants to explore approaches, understand unfamiliar code, and support implementation - checking their suggestions and discussing anything you’re unsure about
  • Write readable code following team standards and verify your changes
  • Run existing automated tests and add basic tests for your changes with guidance
  • Learn how changes move from a pull request to a deployed application, using the team’s automated checks and deployment workflow with support
  • Collaborate with designers, developers, QA, and product owners to understand requirements and deliver features
  • Participate in code reviews, apply feedback, document your work, and share what you learn
  • About you - Tech skills & Experience:

  • Around 1 year of commercial experience in web development
  • Solid JavaScript fundamentals, basic TypeScript knowledge, and a practical understanding of HTML and CSS
  • Hands-on experience with a frontend framework, including components, user interactions, and basic state management
  • Experience building interfaces with forms, handling user input, and displaying data from APIs
  • Basic understanding of HTTP and how an application communicates with a backend
  • Ability to investigate straightforward issues using browser developer tools, error messages, and documentation
  • Familiarity with Git and running applications locally using standard development tools
  • Some experience using AI coding assistants for learning or development, with a habit of checking their output and understanding code before using it
  • About you - Soft skills:

  • Curious about user needs and why a feature matters
  • Ask questions, share progress, and raise blockers when you need help
  • You welcome feedback and use it to improve your work
  • Comfortable acknowledging knowledge gaps and working through them with your teammates
  • Open to learning new tools and gradually exploring backend development
  • Ready to work closely with mentors while building independence and contributing to an Agile/Scrum team
  • English at B2 or above for international collaboration
  • Polish at C1 or above for daily team communication
  • Nice to have:

  • Experience writing basic automated tests
  • Exposure to backend development, databases, or building a simple API
  • Experience taking a personal or commercial application from an idea to a working deployment
  • Basic familiarity with cloud services, Docker, or configuring CI/CD pipelines
  • Experience with a framework that combines frontend and server-side development
  • Recruitment process:

  • CV review
  • Phone call with our Recruiter - 15 minutes
  • Coding assignment - 4 hours
  • Soft-skills interview with our Recruiter - 45 min
  • Technical interview with our Specialists - 2 hours
