Mid Backend Developer (Python → RoR)

🔥 We are looking for a Mid Backend Developer (Python/RoR) — B2B Cooperation 🔥

Project focus: computational models for solar panel performance & energy optimization

At MindPal, we build intelligent, production-ready systems used across the energy, education, and HR-tech sectors. Our team in Gliwice works on products that directly influence business outcomes — including advanced tools for designing and optimizing solar installations.

We’re looking for a Backend Developer with at least 2 years of commercial experience and solid Python experience who is interested in expanding their skills into Ruby on Rails. While the project is primarily developed in Ruby on Rails, you don’t need to be an experienced Ruby developer to join us — we are open to strong Python backend developers who are willing to learn Ruby on Rails and gradually transition into the project’s technology stack.

🟪 Cooperation Description

We offer long-term B2B cooperation on backend projects focused on computational models, solar panel performance, and energy optimization. The cooperation involves developing and maintaining backend components, implementing computational solutions, and contributing to production-ready features and technical improvements. The project is primarily developed in Ruby on Rails, with an opportunity to build on your existing Python backend experience while developing your skills in Ruby and Rails. The cooperation may follow a hybrid model, with occasional on-site collaboration in Gliwice depending on project needs and agreed arrangements.

🟪 What We Provide in Cooperation

• Long-term B2B cooperation on real-world backend projects.
• Opportunity to contribute to advanced solutions for the solar energy industry.
• Access to AI-powered tools and automation supporting efficient project delivery.
• Knowledge sharing and access to technical consultations with experienced backend engineers.
• A collaborative environment focused on technical quality, ownership, and continuous improvement.
• Opportunity to propose and test new technical solutions.
• Additional cooperation options, including access to selected partner services and performance-based additional remuneration, if agreed separately.
• Possibility to participate in weekly onsite English classes with a native speaker, if agreed as part of the cooperation.
• Pet-friendly office in Gliwice 🐶.
