Job description

Quantum Computing Engineer – Algorithms, Cryptography & Post-Quantum Security

Join the Vanguard of Quantum Innovation

Are you the kind of person who builds quantum circuits for fun, excels in hackathons, or has received awards in coding or science competitions? Perhaps you've published research, built projects on Qiskit, or solved complex quantum puzzles?

We seek architects of the future, not followers.

At the forefront of quantum computing and post-quantum security, we are forming a global team of top thinkers, tinkerers, and builders. This role is more than a job—it’s a mission to reshape what’s possible.

What You’ll Do:

1. Build and deploy quantum-secure cryptographic systems
2. Optimize real-world quantum hardware and simulations
3. Contribute to core quantum software platforms used globally
4. Collaborate daily with leading quantum researchers and engineers

What You Bring:

1. Deep knowledge of quantum mechanics, algorithm design, and security principles
2. Hands-on experience with Qiskit, Cirq, or similar platforms
3. Strong Python programming skills and a passion for clean, scalable code
4. A proven track record—hackathons, coding competitions, academic awards, or research achievements
5. Curiosity, grit, and willingness to relocate to join a truly global team
6. (Must reside in UK, Turkey, Brazil, or Morocco)
7. Work at the cutting edge of quantum tech & cryptography
8. Access to state-of-the-art quantum hardware & tools
9. Join a team that values vision, execution, and creative courage
10. Be part of shaping a quantum-secure world

We care less about your educational background and more about what you’ve built, solved, or won.

Send your CV, GitHub, or portfolio of your quantum achievements. If you have competition wins or solo projects you’re proud of, show them off.
