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).
