About the Role
 

Key Responsibilities

Integration Project Coordination
 

• Track all active PBI integration projects, maintaining an up-to-date picture of status, blockers, and next actions across onboardings, configuration changes, and technical remediation
• Act as the day-to-day coordination point between ACE's IT and Engineering teams and external payment partners on all integration matters
• Keep integration timelines moving by following up proactively with both internal and external parties, escalating to the Head of PBI where progress has stalled
• Prepare and circulate clear status updates on active integrations for internal reporting and team reviews
• Schedule and run integration calls, ensuring both sides are prepared, actions are documented, and follow-ups are completed

Technical Bridge and Fact-Checking
 

• Review inputs from both ACE's internal teams and external partners, identifying inconsistencies, gaps, or conflicting information before they cause delays
• Ask the right questions of both sides to ensure integration decisions are based on accurate and complete information
• Validate that proposed configurations and solutions are aligned with ACE's requirements before escalating recommendations to IT for implementation
• Liaise with partner technical teams to gather API documentation, integration specs, and clarification on technical requirements
• Maintain integration documentation including API specs, configuration records, flow diagrams, and issue logs

API Health Monitoring
 

• Monitor the ongoing health and performance of live API integrations across ACE's payment partner network
• Identify anomalies, degraded performance, or suboptimal payload configurations that may be affecting acceptance rates or transaction performance
• Escalate findings to IT and the relevant partners with clear documentation of the issue, observed impact, and suggested next steps
• Track remediation progress on flagged API issues through to resolution
• Maintain a live view of API health across all active partner integrations and provide regular reporting to PBI leadership

Knowledge and Documentation
 

• Build and maintain a structured library of integration knowledge covering partner configurations, known issues, resolution history, and API behaviour
• Capture integration learnings so they are accessible to the wider PBI and IT teams and do not need to be relearned
• Document pre- and post-go-live configurations to support future troubleshooting and partner reviews

What We Are Looking For

Essential
 

• 2 to 5 years of experience in a technical coordination, integration support, or payments operations role
• Strong working knowledge of REST APIs, SDKs, and API-based integration concepts able to read API documentation and identify issues without needing to write code
• Comfortable operating as a bridge between technical teams and commercial or operational stakeholders
• Highly organised with a structured approach to tracking and following up across multiple concurrent workstreams
• Strong written English with the ability to communicate technical issues clearly to both technical and non-technical audiences
• Available during UK business hours or with significant overlap (PKT is UTC+5)

Desirable
 

• Background in payments, fintech, or financial services — familiarity with acquirers, payout providers, open banking, or payment gateways
• Understanding of transaction lifecycles, decline reasons, and acceptance rate drivers
• Experience with tools such as Postman, API monitoring platforms, or project tracking tools
• Exposure to webhook configurations, 3DS authentication flows, or payment routing logic

What We Offer
 

• Competitive salary aligned to experience
• A technically rich coordination role at the centre of a global payments infrastructure function
• Direct exposure to a wide network of international payment partners, acquirers, and banking relationships
• Clear scope to develop deeper payments expertise within a fast-scaling business
