**Employment type:** Full-time

## Description

**About The Vault**

The Vault is a crypto-finance company building an MPC-based crypto custody and wallet platform designed for both institutional and retail users. Our infrastructure combines threshold signing, HSM and hardware-wallet integration with non-extractable key shares, and robust recovery and policy flows across a growing range of chains and assets. We are headquartered in Limassol, Cyprus.

**The Role**

We are looking for a Product Owner to own the end-to-end product vision, roadmap, and requirements for our custody platform. You will be the single point of accountability for defining what the platform builds and why: prioritising the backlog across competing inputs — customer commitments, security audit findings, cryptographic research milestones, and regulatory obligations — and translating cryptographic and security constraints into clear, testable product requirements.

You will act as the primary product interface between cryptography research, engineering, security, compliance, design, and customer-facing teams, and represent the platform externally in partner, auditor, and investor conversations. You will work in close partnership with the Delivery Manager: you set scope, priority, and acceptance, while the Delivery Manager owns execution cadence and release operations.

**What You Will Do**

-   Own and evolve the product vision, roadmap, and requirements for our MPC-based custody and wallet infrastructure.
-   Prioritise the product backlog across customer commitments, security audit findings, cryptographic research milestones, and regulatory obligations.
-   Translate cryptographic and security constraints into clear, testable product requirements with well-defined acceptance criteria.
-   Define core platform capabilities: threshold signing, HSM and Ledger integration with non-extractable key shares, recovery and policy flows, and chain and asset coverage.
-   Lead customer and stakeholder discovery, and produce high-quality written specifications.
-   Make product-level trade-offs between new features, platform hardening, and technical debt.
-   Serve as the primary product interface between cryptography research, engineering, security, compliance, design, and customer-facing teams.
-   Represent the platform externally in partner, auditor, and investor conversations.

## Requirements

**What We Are Looking For**

-   Proven experience as a Product Owner or Product Manager on a technical platform — ideally in digital asset custody, fintech infrastructure, security, or cryptography-adjacent products.
-   Working understanding of custody and key-management concepts: MPC / threshold signatures, HSMs, hardware wallets, recovery and policy engines.
-   Ability to engage credibly with cryptographers, security engineers, and auditors — and to turn their constraints into product decisions.
-   Excellent written specification skills: unambiguous requirements, acceptance criteria, and documentation.
-   Experience balancing regulatory and audit obligations with commercial product goals.
-   Strong stakeholder management and external communication skills; fluent English and Russian.

**Nice to Have**

-   Hands-on experience with blockchain protocols, wallets, or web3 products as a user or builder.
-   Exposure to security audits, penetration testing cycles, or compliance frameworks in a regulated environment.
-   Experience serving both institutional and retail user segments on one platform.

**How Success Is Measured**

-   Soundness and adoption of the product roadmap.
-   Quality and clarity of the requirements handed to delivery.
-   Security and audit posture of the resulting platform.
-   Measurable growth of institutional and retail usage.

## Benefits

-   A central role in shaping the flagship product of a growing crypto-finance company;
-   Competitive compensation package;
-   Annual performance bonus;
-   Flexibility to work fully remotely or from our Limassol office, collaborating closely with a senior, technically deep team;
-   Relocation package and visa support.
