Reconciliation Operations Specialist in London

We are looking for a hands-on Treasury Operations Specialist in London to support new trading entities and expanded product coverage.

The immediate driver is the launch of our OTC exotics business, but the role will broaden over time: you will own the daily cash and collateral heartbeat across our accounts and counterparties and, alongside Trading, Corporate Strategy, Risk, Finance and Group Treasury, help make margin and liquidity a competitive advantage.

You'll bring strong treasury operations experience from a financial markets environment, with practical knowledge of OTC derivatives and cash & collateral management.

This is a hands-on, execution-focused role for someone who enjoys working close to the business and owns problems end-to-end.

The role sits within Finance and partners day-to-day with the business leads: the Equities Exotics trading desk and Corporate Strategy, both based in London.

Counterparty & account management: Maintain the bank, broker and clearer account inventory; open, close and troubleshoot accounts and SWIFT relationships; Report daily on the entity's liquid assets and unencumbered profile; Provide the Treasury view on eligible collateral, margin timing, thresholds and haircuts in CSA, ISDA and PB documentation, partnering with Legal, Operations, Group Treasury and Trading across both BAU and new-entity build-out.

Regulatory & control support: Support treasury-adjacent regulatory reporting and month-end / valuation controls in coordination with Finance.

Partner with Corporate Strategy and Risk on margin implications and clearing economics; support independent margin replication across the products we trade (exchange, bilateral, PB and repo), monitor account balances, fees and financing costs, and feed the global analytics initiative that informs clearing strategy.

Partner with Tech and Group Treasury to move from manual to automated call and settlement workflows; A proactive, solutions-oriented mindset, comfortable operating calmly in a high-performance, time-critical environment.

Control mindset and attention to detail, with the judgement to distinguish a rounding break from a real risk.

Collaborative communicator, comfortable coordinating across Trading, Risk, Legal, Finance and external counterparties, with the instinct to drive issues to resolution rather than pass them along.

With a focus on continuous improvement, we participate in the safeguarding of healthy and efficient markets for everyone who participates.

What you'll get You’ll join a culture of collaboration and excellence, where you’ll be surrounded by curious thinkers and creative problem solvers.

Motivated by a passion for continuous improvement, you’ll thrive in a supportive, high-performing environment alongside talented colleagues, working collectively to tackle the toughest problems in the financial markets.
