Job description

about bright people 🧡

At Bright Inventions we value people who take ownership, show initiative, and care about what they build. We work as partners to our clients, so we look for team members who actively suggest improvements, solve problems, and take responsibility for their work and growth.

Being flexible is important to us. We use technology as a tool to bring value, and we appreciate people who are open to learning and using new tools when needed.

We expect effective communication skills, including the ability to both give and receive constructive feedback with empathy. We focus on solutions, not blame. We support each other, share knowledge, and approach challenges with a positive mindset.

about our projects 🚀

We are building a mobile solution for Relevo – a German sustainability startup revolutionizing takeaway with a reusable packaging system. Operating in 700+ cities and used by over 200,000 people, the platform spans mobile apps, a restaurant-facing dashboard, and a robust backend ecosystem. With challenges like offline functionality and peak-hour stability, we’re shaping a scalable, green tech product that supports real-world impact.
