Senior Java Developer - Digital Trust (CLOSED)

Łódź, Poland (Hybrid)

Full Time

About the Job

Hey! Nice to see you!


Let’s share our story to get to know a bit better…. We are business and technology enthusiasts that are constantly hungry for new challenges, self- and others-development and nothing motivates us more than great software products and happy customers.


At Incubly, we believe that great people want to work with great people, so we started to build such a company that will attract great minds and that we can achieve everything not feeling that we actually work, but just have fun….


Our mission is to mainly support tech companies, and startups (scaleups) in fast and high-quality scale-up of their teams and boost their product development, testing and deployment; so we can succeed together.


We are currently working with a french company that provides innovative solutions to help guarantee the security and legal value of paperless transactions and electronic contracting processes while offering an optimized user experience, across multiple channels, whether online, mobile, in-branch or over the phone.

The solutions allow users to commit to a contract and guarantee the integrity of that commitment through a digital signature function. It also generates enforceable proof that can be used in the event of a dispute.


The solutions are compliant with the European eIDAS Regulation* framework on electronic identification and trust services for electronic transactions in the internal market to create, validate and preserve simple, advanced and qualified signatures.

Electronic contracting and paperless transactions are major strategic tools for strengthening customer relationships, accelerating business growth and improving efficiency. Transforming a contracting process to make it entirely electronic requires securing and giving legal value to transactions, agreements and documents involved.


If you like to work with us, let us share our need for competence - we look for a Senior Java Developer.
