Senior Software Architect

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.

As a Senior Software Architect, you will lead the design and integration of our software stack, ensuring seamless interaction between hardware-accelerated computation and embedded firmware running on ASIC, to high-performance system-level software orchestrating large-scale computations across multiple devices. You will work closely with hardware, cryptography, and software teams and be a key-decision-maker in software architecture choices, ensuring scalability, performance, and maintainability across the entire system.

We offer the Opportunity to deeply influence cutting-edge privacy-preserving technology with the highest performance.

Influence both silicon-level and large-scale system design

Work with highly skilled multidisciplinary counterparts
