Job Specifications

Who we are

We are a deep-tech cybersecurity company building advanced cryptographic products that help organizations discover, manage, govern, and transition their cryptographic assets in an increasingly regulated and post-quantum world.

Our products are deployed in complex enterprise, governmental, and security-critical environments where correctness, compliance, and long-term maintainability are non-negotiable. Product decisions directly influence customer security posture, regulatory readiness, and operational risk.

We are now looking for a Head of Product to own the product function end-to-end, from strategic vision and market positioning to execution, revenue impact, and lifecycle management. This is a hands-on doer role: you will personally drive delivery, write specifications and product assets, and actively support the field (pre-sales, demos, and key customer interactions).

On a daily basis, you will

This role is not only about defining strategy: you are expected to be hands-on and deliver outcomes, from writing specifications and product artefacts to supporting customer-facing initiatives.

Product Strategy (30%)

Define and own the long-term product vision, positioning, and portfolio strategy, aligned with company goals and market evolution.
Be accountable for the business success of the products, including pricing strategy, packaging, and revenue contribution.
Build and maintain clear product business cases and investment rationales.
Continuously monitor cryptography, cybersecurity, and regulatory trends (post-quantum transition, crypto-agility, inventories, compliance) and translate them into product opportunities.
Ensure product alignment with relevant cryptographic standards, certifications, regulations, and best practices (e.g. NIST, ANSSI, ETSI, ISO), and anticipate upcoming changes.

Product Execution and decision authority (15%)

Translate strategy into clear, prioritised roadmaps with full ownership over scope, sequencing, and trade-offs.
Write and maintain user stories, functional definitions, acceptance criteria, and detailed specifications (PRDs and functional/technical specs).
Serve as the final decision-maker on product priorities, balancing customer needs, technical constraints, time-to-market, and strategic objectives.
Work closely with R&D to frame problems, validate requirements, and ensure high product quality and consistency.
Own the entire product lifecycle, including versioning, backward compatibility, deprecation, and end-of-life strategies.
Define and manage migration and transition paths for customers, especially in the context of crypto-agility and post-quantum readiness.

Product Management and Product Marketing (25%)

Own go-to-market execution in close coordination with Sales and Marketing: positioning, differentiation, messaging, and buyer journeys.
Produce sales enablement assets for direct sales: pitch decks, one-pagers, battlecards, demos scripts, FAQs, and pricing/packaging materials.
Produce sales tools and enablement kits for indirect sales / channels: partner pitch decks, channel playbooks, reseller training, and co-selling assets.
Structure internal and external product documentation (quickstarts, release notes, change logs) to support scalability and customer autonomy.

Pre-sales support to Sales and Marketing (20%)

Act as a direct interface with customers and prospects (including key accounts) during discovery and pre-sales cycles.
Support Sales and Marketing with demos, presentations, product deep-dives, and contribution to RFP/RFI responses.
Lead product discovery through hands-on customer engagement, workshops, and field feedback, and ensure learnings influence roadmap decisions.
Represent CryptoNext in relevant industry events (conferences, webinars, and trade shows) when product expertise is required.

Organization, leadership, and enablement (10%)

Define and implement robust product management methodologies (discovery, prioritization, feedback loops, metrics).
Define and track product KPIs (adoption, usage, value delivered, revenue impact).
Enable Sales, Marketing, and Professional Services through clear narratives, playbooks, and training.
Build, lead, and grow the Product team as the company scales.

Technology Partnerships and Alliances (10%)

Define and execute a technology partnership strategy to accelerate adoption, strengthen interoperability, and amplify go-to-market impact across the cybersecurity ecosystem.
Identify, qualify, and onboard strategic partners (technology vendors, platforms, integrators, and ecosystems) that increase product credibility and distribution in regulated environments.
Drive partner-led product integrations and technical alignment: Own the partner operating rhythm and outcomes: pipeline influence, partner-sourced opportunities, integration adoption, deal acceleration, and feedback loops into the roadmap.
