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.

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.

Competitive compensation package;
