About us

We're hiring on behalf of our partner — a company that powers the operations behind regulated and high-risk industries. 

They give fast-moving businesses in these spaces the structure, compliance and talent they need to scale — without slowing down.

About the Role

Crypto never sleeps, and once something settles, it settles — there's no chargeback, no "undo," no calling the bank to reverse it. That's basically the whole job in one sentence: you make sure every deposit, withdrawal, trade settlement, OTC leg, staking payout, and institutional transfer goes out right, on time, every single time.

We're talking about millions of dollars in client and corporate assets moving every year, where one wrong address or wrong network is permanent. So yeah, this is a serious role — but we're not looking for someone who's stiff or robotic about it. We want someone who's genuinely good under pressure, sharp with details, and treats "100% accuracy" as just... the normal standard, not some heroic achievement.

You'll run settlement day-to-day, own how the whole thing is controlled, and be the person people come to when something's about to go sideways — right before it reaches the Deputy CFO.

What You'll Do

Keep Settlements Moving (and Correct)

• Own settlement end-to-end — crypto in/out, fiat payouts, stablecoin transfers, OTC trades, institutional funding, all of it
• Make sure everything lands on the right asset, right network, right memo/tag, right address — no exceptions
• Get comfortable working across multiple chains (BTC, ETH, L2s, Solana, Tron, etc.) — gas fees, congestion, reorgs, all the fun stuff
• Work inside dual-control / four-eyes setups — approve what's yours to approve, escalate what's not
• Personally handle the high-stakes, VIP, and institutional settlements — including proper callback checks before anything moves

Keep Everything Reconciled

• Own daily reconciliation across on-chain balances, exchange ledgers, custodians, and bank accounts — unexplained gaps aren't really a thing you let slide
• Make sure client and company money never mix, and keep the paper trail to prove it
• Chase down the weird stuff — stuck transactions, wrong-network deposits, dust, lost memos — until it's actually resolved
• Keep a clean break log and root-cause tracker, and give Finance a clear weekly picture

Manage Wallets & Liquidity

• Keep hot/warm/cold wallets funded and balanced so settlements never get stuck waiting on liquidity
• Take part in signing operations (MPC / multi-sig / HSM) — quorum ceremonies, break-glass procedures, the works
• Look ahead and flag liquidity shortfalls before they become actual problems
• Be the go-to person for custodians, banks, PSPs, market makers, and liquidity providers when something needs sorting

Own the Controls

• Build and maintain the settlement control framework — whitelisting, limits, velocity checks, approval matrices, audit trails
• Run pre-transaction screening (Travel Rule, sanctions, Chainalysis/Elliptic/TRM) and hold anything that looks off
• Be the person audits and regulators talk to when they want to understand how settlement actually works
• Keep runbooks and disaster recovery plans current — and actually tested, not just filed away
• Make sure no single person, including you, can move client funds solo

Handle the Bad Days Well

• Step up when things break — delayed withdrawals, banking outages, custodian downtime, chain halts, forks, anything sketchy
• Lead the freeze/recall/recovery call alongside Compliance, Risk, Legal, Security, and Support
• Turn every incident into a lesson — update the controls so it doesn't happen the same way twice

Build the Team & Make Things Better

• Lead and grow the settlement team across a 24/7 setup — clean handovers, clear escalations
• Push for automation wherever it makes sense — fewer manual steps, better tooling, less room for human error
• Work with Client Support on explaining settlement issues in plain language when clients need answers
• Own the KPIs and be ready to explain them to leadership — and occasionally the Board

Who You Are

• 3–5+ years in settlement, payment ops, treasury, custody, or back-office roles in financial services — with at least a year leading a team
• You've actually done crypto settlement hands-on — exchange, custodian, OTC desk, market maker, prime broker, whatever the setting, it needs to be real experience
• Fluent in English and Russian
• You genuinely get on-chain mechanics — addresses, memos, confirmations, fees, chains, token standards — and you know exactly what happens when one of them goes wrong
• You've owned reconciliation at real volume, not just reviewed someone else's spreadsheet
• You know your way around fiat rails too — SWIFT, SEPA, Fedwire/ACH, Faster Payments, plus stablecoin on/off-ramps
• You've worked inside dual-control, audited environments, and you actually understand why those rules exist
• You've been through a real settlement crisis and lived to tell the story
• You've got sharp attention to detail, but also good judgment — you know what to quietly fix, what to escalate, and what's genuinely worth waking the CFO up for

If you're the person your last team called when something needed to move right, fast, and with zero drama — apply now.

• Multiple salary payout options (flexible formats);
• …And many more perks unlocked after we hit break-even.
