Cybersecurity Specialist – Quantum Security

Business Area: Technology – Cybersecurity
Contract: B2B
Location: Kraków, Poland
Work model: Hybrid – 6 days per month from the Kraków office

About the role

We are looking for an experienced Cybersecurity Specialist with a strong background in cryptography and secure engineering to support initiatives focused on preparing technology environments for the transition to quantum-safe security.

In this role, you will provide expert guidance on cybersecurity and cryptography, helping technical teams make secure, risk-informed decisions. You will work across a range of initiatives, from assessing cryptographic risks and solution designs to supporting migration planning, remediation approaches, pilots and proof-of-concepts.

The role combines cybersecurity expertise, cryptography, security architecture and stakeholder engagement, with a strong focus on translating complex security topics into practical recommendations and engineering-ready guidance.

Key responsibilities

Cybersecurity & cryptography advisory

• Provide expert guidance on quantum-safe security and cryptographic risks.


• Advise on areas such as TLS, PKI and certificates, key management, transport security and cryptographic standards.


• Translate security objectives into practical requirements, guidelines and engineering recommendations.


• Assess technical options, trade-offs and risks and provide clear, pragmatic recommendations.

Security architecture & solution review

• Review solution designs and technical approaches from a cybersecurity perspective.


• Assess proposed solutions against security principles, standards and controls.


• Support threat modelling and security-by-design activities.


• Help define secure and scalable remediation and migration patterns.

Hands-on delivery support

• Support technical workstreams related to cryptographic discovery, prioritisation and migration readiness.


• Help teams interpret security and cryptographic inventory data and identify priorities.


• Provide guidance on dependencies and prerequisites for quantum-safe migration, including transport security and certificate lifecycle improvements.


• Support pilots and Proofs of Concept by defining security requirements, success criteria and safe deployment approaches.

Risk management & assurance

• Identify and articulate security risks, control gaps and required remediation actions.


• Provide input to risk assessments and risk acceptance decisions.


• Help ensure that security documentation is clear, traceable and suitable for governance and assurance purposes.


• Capture lessons learned and contribute to improving security standards, patterns and guidance.

Stakeholder collaboration

• Work closely with technical and non-technical stakeholders across different areas of the organisation.


• Explain complex cybersecurity and cryptography topics in a clear and accessible way.


• Provide recommendations that enable teams to move forward while maintaining strong security outcomes.


• Contribute to knowledge-sharing and the development of best practices around quantum-safe security.
