Are you excited about solving the hardest problems in quantum computing? Would you like to be part of a team building real-world quantum solutions that run on today's quantum computers? Are you willing to drive and shape what this technology becomes next?
QMill builds quantum-powered solutions for data security and optimisation across defence, telecom, finance, energy, and transport. We turn promising quantum algorithms into products that utilize today's real quantum computers. QMill is headquartered in the greater Helsinki area in Finland, one of the world's leading quantum communities, and we are growing internationally through an expanding network of sites, with the UK among the first. Our team brings together people of many different nationalities, and we are well networked internationally and actively cooperating with the leading players in the field.
We are now looking for a quantum algorithm engineer to join our quantum-powered data security team. You will be based in the UK, collaborating with the research team in Finland and working closely with the local QMill office in UK. Your key goals are to design and develop data security protocols that utilize quantum algorithms and are integrated into our data security products. You will cooperate with other quantum algorithm engineers and software developers in the team.
While an extensive background in quantum computing is not mandatory, we're looking for someone with experience in cryptography, algorithm development and a keen interest in learning more about quantum computation, quantum algorithms and how to use them to solve real-world problems.
What will you do
Design and develop cryptographic protocols that utilize quantum algorithms as part of the solution
Design and develop quantum algorithms for quantum-powered data security products
Cooperate with other quantum algorithm developers and software developers in the team
We are looking for
Minimum of 3 years of experience in cryptography either in academia or industry
Knowledge of the basics of quantum computing and quantum algorithms and interest in developing quantum algorithms.
Experience in quantum algorithm development is a plus.
Strong systematic thinking and adherence to good software development practices
Strong background in mathematics, physics or computer science
Evidence of efficiency in studies and / or work tasks.
Master’s degree in computer science, physics or mathematics. Ph.D. and especially postdoctoral experience are a plus
What you need to succeed
Good at communicating and collaborating with people
Fluent in written and spoken English
Proactive and creative
Efficient and productive
Able to identify and solve problems independently and understand the big picture to provide input at all stages of project work
Flexible and adaptive to handle uncertainty of dynamic research topics
Curiosity and drive to explore the potential of quantum computing
What we are offering
Visionary work in quantum algorithms for data security. We build practical solutions at the frontier of quantum computing for quantum-powered security and optimization solutions across defence, telecom, finance, energy, and transport.
Solving ambitious problems with an exceptional team. QMill brings together experienced scientists, engineers, product developers, and business professionals with the ambition and capabilities to build genuinely useful quantum-powered solutions.
Having a real influence on what we build. We value curiosity, sound judgement, and people who develop ideas together. Your contribution can shape our technology, product priorities, customer value, and business.
Growing with a rapidly advancing field. As quantum computing moves from research toward real-world adoption, you will tackle new challenges, broaden your expertise, and help define what useful quantum computing can become.
Support for your well-being. Without our personnel we cannot succeed, so we take good care of them. We nurture great team spirit and leadership and enable a good work-life balance.
