Presales / Sales Engineer — SME Cybersecurity

Global data creation is exploding. Only ~30% of the world's data is durably stored, and data centers already consume around 2% of global electricity. As volumes double every few years, the silicon-based storage model is reaching its structural limits.

Biomemory is a global pioneer in the DNA data storage market. We develop IT-friendly DNA Data Storage and cybersecurity solutions engineered for data center environments. Our interoperable, modular architecture combines biosecure DNA media, industrialized end-to-end write / store / read processes, and an interoperable IT interface — creating a brand-new storage tier optimized for density, longevity and operational efficiency.

Founded in 2021 and headquartered in Paris, we closed a €17M Series A in early 2025 (led by Crédit Mutuel Innovation, with Bpifrance, Blast and others) and were selected as a French Tech 2030 laureate. We're scaling fast — we acquired one of our competitors based in the US and now we're bringing our offer to market.

Join us in redefining the future of data storage.

About the Role

As our Presales / Sales Engineer for Cybersecurity, you're the technical backbone of every deal. You partner with the sales team to turn a world-first technology into a trusted, defensible solution in the eyes of CISOs, security architects and infrastructure teams.

You'll own the technical narrative on cyber-driven opportunities — from first demo to proof of concept — translating Biomemory's biosecure DNA storage into concrete answers on data protection, long-term integrity, air-gapping and compliance. This is a founding-level presales role: you'll help define how we demo, scope and win.

Your missions

Act as the technical expert alongside sales on cybersecurity-driven opportunities.

Lead technical discovery: understand the customer's security architecture, threat model and compliance constraints.

Design and present the Biomemory solution tailored to each account's data-protection and long-term-preservation needs.

Build and deliver compelling demos, technical presentations and workshops.

Proof & credibility

Scope, run and support Proof of Concepts (PoCs) and technical validations.

Respond to RFIs / RFPs, security questionnaires and technical due-diligence requests.

Position Biomemory against the status quo (silicon storage) on resilience, immutability, air-gapping and data sovereignty.

Voice of the market

Feed field insights and technical objections back to Product to sharpen the roadmap.

Help build the reusable presales toolkit: demo scripts, reference architectures, technical FAQs.

About You

6–8 years of experience in a presales / sales engineering / solutions architect role, ideally in cybersecurity, data protection, storage or enterprise IT infrastructure.

Solid understanding of cybersecurity fundamentals: data security, encryption in transit/at rest, backup & archival, immutability, air-gapping, and relevant compliance frameworks (e.g. GDPR, NIS2, ISO 27001).

Comfortable engaging CISOs, security architects and IT decision-makers and earning their technical trust.

Proven ability to run PoCs, technical workshops and compelling demos.

Enjoys explaining complex, early-stage / category-defining technology in clear business terms.

Fluent in English and French; comfortable in an international B2B environment.

Autonomous, hands-on, entrepreneurial — you thrive in a fast-moving startup with a blank page.

Genuine interest in sustainability and in solving the coming data crunch.

Contract: CDI, full-time

Location: Paris HQ, hybrid — with occasional travel across Europe and to the US

Team: You'll join the Product organization under Vincent Franceschini, working in tight partnership with the sales team
