Informacje o stanowisku

Our client is developing a decentralized AI platform powered by blockchain, enabling the swift creation, sharing, and monetization of AI services. The platform operates as a marketplace where developers can publish and sell various AI tools, while users can test, purchase, and use them.

The project’s mission is to create an open and independent artificial general intelligence, accessible to everyone, dedicated to benefiting humanity and remaining free from the control of individual companies or governments.

We seek an experienced API Engineer with deep experience in extending APIs and building high-performance solutions within the Cosmos ecosystem. The ideal candidate will have a solid understanding of blockchain architecture and distributed systems and a proven track record of developing secure, scalable, and robust APIs. This role will focus on extending API functionality to enable seamless integration with Cosmos SDK-based blockchains, leveraging Tendermints consensus engine and related tools.

We offer:
- Daily support for your technical and personal growth;
- Professional and very friendly team, that is always ready to help and support;
- Flexible working hours;
- All official holidays;
- 15 days of paid vacation;
- The company provides all the necessary equipment;
- Fitness support upon request;
- English classes up to three times a week;
- The company pays 50% of the cost of refresher courses for any employee of the company;
- Workstation space;
- Mentoring and Educational Programs;
- Regular Activities on a Corporate level (Team Buildings, Sports Events, Table Games, Tech Events);
- Advanced Bonus System.

We thank all those who apply, however, there is a possibility from our side, of not responding to some candidates who do not match the requirements, due to a large number of applicants. Thank you for your understanding.

• At least an Upper-Intermediate level of English.
• 5+ years of experience in API development, with at least 2+ years specifically working with blockchain technologies.
