Why Join Us?
A successful candidate will be a very strong programmer with current Java development experience. They must also be curious, open-minded, and desire to learn new things. English proficiency is a must.
This role is for developers who excel at programming core Java from the ground up, not just integrating frameworks or APIs. If you’re fascinated by understanding systems ‘under the hood,’ this role is for you. Successful candidates enjoy geeking out about data structures and debugging application performance issues.
This is a fully remote backend Java development role for a developer in Poland. You will be working through a Polish company that will provide the support and administrative assistance to make you successful in the role. We are looking for people to join the team long-term.

- Professional growth: Collaborate with smart, highly capable developers in a supportive and challenging environment.
- Direct collaboration: You will work directly with the client team in North America and in Poland.
- 1st-tier work: This is not a technical support or legacy maintenance role. The system is functional and is actively being built and you will take part in updating it. The people who built the system are still part of the team.
- Long-term commitment: This is not a fixed-scope or fixed-term outsourcing role; we value people who want to grow and contribute long-term.
- Flexibility & remote work: Fully remote position based in Poland with increasing schedule flexibility post-onboarding.
- Competitive Compensation: Top pay and ample time-off options.
