Bybit - Wallet Custody Operations Director

• Wallet Operations & Rebalancing • Own and execute the daily operational cycle of hot, warm, and cold wallet management across all supported assets and networks • Define and maintain rebalancing thresholds and triggers — ensuring hot wallets hold sufficient liquidity for withdrawals while minimising exposure • Monitor wallet balances in real time; respond to alerts for low-balance, large outflows, or anomalous patterns • Execute and authorise inter-wallet transfers (hot → warm → cold and vice versa), including multi-sig coordination with custodians or internal key holders • Maintain SOPs for routine rebalancing operations and escalation procedures for off-cycle events • Track gas/fee reserves across networks (ETH, BTC, TRON, Solana, etc.) and ensure fee wallets are topped up • Coordinate with the treasury/finance team on asset flow reporting and reconciliation • Wallet Structure Advisory for Regulated Sites • Provide operational inputs during licensing applications or regulatory reviews — documenting how client funds are segregated, custodied, and protected • Design and recommend wallet architectures that meet jurisdictional requirements — including cold storage minimums, custodian approvals, and client asset segregation rules • Work with legal and compliance teams to prepare wallet-related documentation for regulators (e.g., asset safeguarding policies, custody arrangements, asset-liability matching) • Assess custody provider options (Fireblocks, Copper, Ceffu, BitGo, etc.) against regulatory expectations for each jurisdiction • Flag operational risk or structural gaps ahead of audits or regulatory inspections • Ensure wallet structures are scalable and adaptable as the exchange expands into new regulated markets • Proof of Reserves (PoR) Setup & Operations • Lead the design and implementation of PoR programmes for each site/entity — from methodology selection through to public publication • Select and engage third-party auditors or verification partners; manage the relationship and audit cycle • Define the PoR data scope: which assets, which wallets, which liabilities (snapshot definitions) • Coordinate on-chain signing and Merkle tree construction with the engineering team to verify user liability coverage • Build and maintain internal tooling or workflows to generate PoR snapshots on schedule (monthly, quarterly, or ad hoc) • Respond to questions from users, auditors, or regulators on PoR methodology and results • Stay current on evolving PoR standards and update methodology accordingly • Ensure PoR results are consistent with internal reconciliation reports and finance records • Wallet Team & Security Collaboration • Serve as the operational counterpart to the Wallet Engineering and Security teams — translating business requirements into technical specifications and vice versa • Participate in wallet infrastructure design reviews: new chain integrations, MPC/HSM upgrades, multi-sig policy changes, smart contract wallet deployments • Drive the operational readiness checklist for any new wallet setup — key ceremony procedures, signing policies, access controls, DR/BCP scenarios • Collaborate on key ceremony planning and execution (cold wallet creation, custody onboarding, signing authority changes) — ensuring proper documentation and witness procedures • Conduct regular operational reviews with security: address findings from penetration tests, internal audits, or incident post-mortems • Contribute to and review the Threat Model for wallet infrastructure; identify operational mitigations where technical controls are not sufficient • Champion ongoing enhancements — proactively identifying process inefficiencies, latency bottlenecks, or risk gaps in the current setup • Risk, Controls & Incident Management • Own the wallet-related operational risk register; assess, track, and mitigate risks • Define and enforce transaction approval limits, dual-control requirements, and segregation of duties across the wallet ops team • Act as incident commander for wallet-related issues (stuck transactions, incorrect sends, suspected compromise) — lead the triage, contain the impact, and drive the post-mortem • Maintain a 24/7 on-call escalation framework for critical wallet events • Ensure all wallet movements are logged with full audit trails; support forensic investigations as required • Reconciliation & Reporting • Ensure wallet balances reconcile with exchange ledgers and on-chain state on a daily basis • Partner with finance and product to resolve discrepancies, failed transactions, or asset suspension events • Produce regular management reporting: wallet utilisation, rebalancing activity, PoR status, cold/hot ratio, incident log • Support external audits (financial, security, regulatory) by providing wallet-related data and documentation • Team Leadership & Development • Recruit, manage, and develop a team of wallet operations analysts/engineers • Set team KPIs, OKRs, and performance standards • Build a culture of operational rigour, security-first mindset, and continuous improvement • Create and maintain runbooks, SOPs, and training materials to ensure operational resilience and knowledge retention • Foster strong cross-functional relationships with Tech, Compliance, Legal, Finance, Risk, and Customer Support
