Senior Back-end Developer/ Lead (offline)

We are looking for a Senior Back-end Developer/ Lead to join our fast-growing fintech team!


What are we building:

A payment solution for clients, agencies, and freelancers from service industries, offering industry-grade contracts where transactions are split into incremental and upfront installments, all backed by Escrow (safe vault). Every deal and feedback to it is added to the Professional on-chain passports, which are used to prove reputation, delivered work, and experience.


Why it matters:

Regardless of how clients, freelancers, and service delivery companies conduct business, all parties face regular financial losses due to non-payments, delayed payments, and ever-growing freelance marketplaces’ fees.

A freelancer’s trackable work on marketplaces is their key asset, but they lack ownership over their profiles, risking the loss of valuable data-backed trust.



Midcontract will be the only platform out there offering 100% Escrow for all contract types, as well as fiat and crypto support, combined with the extreme speed of money delivery (5x faster than Upwork, 8x faster than in paper contracts), and low fees. Freelancers and agencies will obtain On-chain Passports with lifetime control over their work history and reputation


Opportunity :


- Joining our team means being part of a dynamic, fast-paced environment where your contributions can shape the future of our Fintech solution for freelancers.

- As an early member of our team, you’ll have a unique chance to leave your mark on our journey. Your ideas and expertise will play a pivotal role in influencing the direction, growth, and success of our product.
