No formal openings right now. The profiles below are the ones we most want to hear from. We read every open application and get back to you when there is a fit.
What you would work on
- A discovery engine that inventories cryptography in source code (Python, JavaScript / TypeScript, Java, Go, C / C++), X.509 certificates and live TLS endpoints.
- Open standards: CycloneDX 1.6 CBOMs, NIST FIPS 203 / 204 / 205 (ML-KEM, ML-DSA, SLH-DSA) and the EU post-quantum roadmap.
- Regulated customers in finance, insurance and energy, who need evidence for DORA, NIS2 and the Cyber Resilience Act.
- Public, checkable work, such as our verified scan of pyca/cryptography and our post-quantum guides.
How we work
- Evidence before claims. Every figure we publish comes from a scan you can reproduce, or is labelled illustrative.
- Customer code stays with the customer. The product runs on-prem or air-gapped; we design for that from day one.
- Open formats, no lock-in. Outputs are CycloneDX, PDF and SARIF.
- Hybrid. Remote and in-person days, from France. KOR IT, the company behind CRYPTAGION, is based in Bordeaux.
Profiles we want to hear from
Cryptography expert
You know how cryptography is really used in software, and you want to help organisations move to post-quantum algorithms without breaking things.
What you would do
- Improve how we detect and score classical and post-quantum algorithms in code, certificates and TLS.
- Shape migration guidance: ML-KEM, ML-DSA, SLH-DSA, hybrid key exchange, certificates and PKI.
- Write and review our technical guides, and follow ANSSI, BSI, ENISA and NIST publications.
- Support customer assessments and explain findings to security teams.
Who we are looking for
- Solid applied cryptography: protocols, TLS, PKI and key management.
- Working knowledge of the NIST post-quantum standards and European agency guidance.
- Able to read code in at least one of Python, Java, Go or C.
- Clear writing in English; French is a plus.

Marketing specialist
You can turn deep technical work into content that CISOs, risk teams and procurement actually read, and you like measuring what works.
What you would do
- Plan and write content for security, risk and procurement buyers in France and the EU.
- Run our guides, LinkedIn presence, newsletters and events.
- Build demand generation for regulated sectors around DORA, NIS2 and the EU post-quantum deadlines.
- Track results and report on what brings qualified conversations.
Who we are looking for
- B2B marketing experience, ideally in cybersecurity or enterprise software.
- Strong writing in French and English.
- Comfortable with technical subjects and regulated buyers.
- Hands-on with web analytics and content tools.
