Job Description

Cryptographic Engineer

We are partnering with a leading blockchain organisation called NEM Group.

As a Cryptographic Engineer, you will work with a team of distributed systems experts and protocol engineers to implement new cutting-edge cryptography in enterprise-grade, public blockchain protocols. You will help design and develop new technologies that improve the privacy, security and resiliency of our products, and interpret and implement solutions based on cutting edge academic research.


At NEM Software, we build real-world applications that help realize the promise of blockchain. We are a multicultural startup of dreamers, designers and developers that create disruptive technologies that enables our customers to accelerate their digital transformation. We move fast, fail fast, and dream big.


NEM Software is not for everyone. We work in a fast-paced environment that requires constant collaboration; we keep bureaucracy to a minimum, and hold ourselves accountable in our mission. We move as a one team; we underpromise, and over deliver. We're customer obsessed, and pride ourselves on our transparency and consistency. If that sounds like your kind of environment...welcome to the team
