Junior Backend Developer Position

Chain Reaction designs and builds hardware that fuels disruptive blockchain technologies by accelerating compute performance. Our world-class teams are transforming the future of data, creating the infrastructure that will power the next generation of secure, scalable, green computing. The main bottleneck in scaling cutting-edge solutions in privacy tech, data analysis, and real-time computing is acceleration – existing hardware cannot keep up with data processing needs. Chain Reaction’s products reshape how data is processed and used on a global scale, and we’re looking for the brightest people to join us.

We’re growing our R&D team and looking for exceptional new graduates with experience to join us in building cutting-edge, multidisciplinary solutions in blockchain and privacy technologies.

In this role, you’ll work with experienced developers across the entire development lifecycle — from planning and design to implementation, testing, and delivery.

Your primary focus will be on our privacy-focused product, helping implement the product’s interface layer, which connects user and datacenter software. Your work will directly impact the functionality, performance, and usability of the product.

This is a great opportunity to gain more hands-on experience, collaborate on a large-scale product, and build real-world skills as part of a high-performing team based in our Tel Aviv office.
