Key Account Manager

Founded in 2019 as a spin-off from Inria, CNRS and Sorbonne University, CryptoNext Security is a European pioneer in post-quantum cryptography and crypto-agility. As a software vendor, our mission is to help organisations migrate their IT systems and products toward quantum-safe, crypto-agile architectures.

Our platform supports the entire post-quantum transition, across three product lines: discovery of cryptographic assets to expose risks and blind spots; crypto-agility management to govern policies and steer the transition of business applications; and remediation toward quantum-safe solutions for a smooth, controlled migration.

We serve major enterprises, public institutions and system integrators across financial services, defence, industry and the public sector.

This is no longer a speculative market. National security agencies have published their migration timelines, the standards are settled, and organisations are moving into implementation. Demand runs on a regulatory clock, not a discretionary budget cycle.

You own our direct revenue: defining the commercial strategy for enterprise, government and OEM accounts, and executing it end to end — from first outreach to signed purchase order.

Direct sales are our immediate source of revenue, and the RFPs on our desk are substantial and well structured. This role exists to win them, and to build the account strategy that turns individual deals into a repeatable enterprise motion.

You report to the CEO and work closely with Channel Sales, Marketing and Product. As the direct business matures, this role has a natural path toward broader commercial responsibility across both direct and indirect channels.

•     Commercial strategy for direct accounts — large enterprise, government — and for OEM customers

•     Prospecting and lead generation on target accounts

•     Discovery and qualification of opportunities

•     Proposal construction and RFI / RFP responses

•     Industry events and conferences

•     Forecasting and reporting, and disciplined use of the CRM and sales stack

•     5+ years in B2B technology sales, including experience building relationships with global enterprise accounts

•     A track record in complex, long-cycle sales within cybersecurity, infrastructure or infrastructure software

•     Comfort in an environment where the processes do not exist yet, and the credibility to hold a technical conversation with demanding buyers

•     Fluency with modern tools to accelerate lead generation, presentations and complex RFP responses

•     Fluent French and English

Familiarity with cybersecurity, cryptography or PKI is a real advantage, but not a requirement — we will bring you up to speed on the technology.

•     Full ownership of the direct business, reporting to the CEO

•     An international territory and a path toward broader commercial responsibility

•     A market driven by regulatory deadlines rather than economic conditions

•     Deep scientific foundations, led by recognised experts in the field

•     Introductory call

•     Interview with the CEO

•     Working session: a deep dive into what you have built, and where we go from here
