About ExeQuantum

ExeQuantum is a Melbourne-based company pioneering post-quantum cryptography (PQC) and sovereign-grade secure systems. We are working with critical industries and governments to deliver solutions that are sovereign, transparent, agile, and compliant. Our projects range from PQC-as-a-Service APIs to secure integrations in finance, healthcare, and national infrastructure.

The Role

We are looking for a Software Engineer to join our engineering team. This role reports directly to the CTO and will involve building prototypes into production-ready solutions across cryptography, email security, and payment infrastructure.

This is not a generic coding role. You will be working on systems where discipline, confidentiality, and creativity matter as much as technical skill.

Responsibilities

  • Design, develop, and maintain secure software components (Python, , C/C++/Rust depending on project scope).
  • Integrate PQC algorithms (ML-KEM, ML-DSA, HQC, FN-DSA, etc.) into real-world applications.
  • Contribute to internal tools, SDKs, APIs, and add-ins (e.g., Outlook, payment gateways).
  • Collaborate with the CTO on system design and architecture.
  • Follow strict security and confidentiality practices.
  • Participate in code reviews, testing, and documentation to ensure auditability and compliance.

What We Are Looking For

  • Open-mindedness and willingness to study cutting-edge technologies. Demonstrated ability to think outside the box and avoid "impossible" as a default answer.
  • 3+ years of professional software development experience (startup or high-assurance sector preferred).
  • Strong skills in at least one of: Python, , C/C++/Rust.
  • Familiarity with cryptographic libraries, secure coding practices, or networking protocols is a plus.
  • Comfort working with prototypes, debugging, and delivering solutions in ambiguous/problem-solving contexts.
  • High standard of confidentiality and discipline in handling IP, code, and client data.

Nice to Have

  • Exposure to PQC or traditional cryptographic systems.
  • Experience with secure APIs, PKI, FIDO2/WebAuthn, or identity systems.
  • Contributions to open source (with appropriate respect for IP boundaries).
  • Knowledge of compliance frameworks (ISO 27001, GDPR, HIPAA).

What We Offer

  • Opportunity to work at the frontier of PQC and sovereign security.
  • Direct collaboration with the CTO and founder team on impactful projects.
  • Market rate hourly salary with major growth potential.
  • Equity / upside opportunities for early team members.
  • Flexible work arrangements (remote-friendly, async-first).

How to Apply

Send your CV, links of your code repositories (GitHub, GitLab, etc.), and a short note about why you want to work on PQC and secure systems with ExeQuantum to
