Product Owner - Digital Asset Custody / MPC

The Vault is pleased to announce a vacancy for the position of Product Owner (Digital Asset Custody / MPC)

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: prioritizing 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. - Prioritize 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.
