Responsibilities and impact:

• Collateral Workflow Management: Provide daily support to subscribers on end-to-end margin call workflows, including Variation Margin (VM) and Initial Margin (IM).

• Trade & Position Normalization: Handle complex data sets to ensure accurate calculation of Net Exposure and Required Margin within the TriResolve environment.
• Regulatory Compliance: Actively monitor and educate clients on evolving market regulations (EMIR, Dodd-Frank, and UMR Phases) and their impact on collateral requirements.
• Product Evolution: Collaborate with Product Management and Developers to provide feedback on margin-specific features, such as Optimization, Interest Processing, and Inventory Management.
• Quality Assurance: Participate in UAT testing for new platform functionalities, ensuring the tool remains the market leader in collateral automation.

What we're looking for:

Fundamental requirement:

• Collateral Proficiency: Understanding of the margin call lifecycle, including issuance, pledge acceptance, a settlement.
• Data Analysis: Proficiency in using text editors and advanced spreadsheet functions to interpret trade valuations and collateral eligibility lists.
• Client Relationship Skills: Ability to manage high-pressure situations, such as resolving time-sensitive margin disputes or settlement failures.
• Operational Agility: Ability to work in a fast-paced environment where market volatility can lead to sudden spikes in margin call volumes.
• Communication: Strong verbal and written English skills; the ability to explain complex financial movements to both back-office operations and front-office risk managers.

Additional preferred requirements:

• Market Knowledge: In-depth understanding of OTC Derivatives and the trade lifecycle, specifically regarding how trade economics drive collateral movements.
• Regulatory Literacy: Familiarity with Uncleared Margin Rules (UMR) and the operational requirements for exchanging Initial Margin (IM).
• Legal Familiarity: A basic understanding of ISDA/CSA documentation and how various parameters (rounding, thresholds, currency haircuts) affect margin calculations.
• Technical Interest: A keen interest in Fintech and the automation of legacy manual processes through SaaS solutions.
