Job description

UK - API Integrations Implementation Specialist

Full Time London, England, GB

6 days ago Requisition ID: 1092

Salary Range: £53,000.00 To £68,000.00 Annually

Location: Remote in the UK
Why this role exists

OpenExchange delivers virtual and hybrid events for the world's largest investment banks, alongside hundreds of corporate clients and organizations. More than half a million virtual meetings and over two thousand conferences have run on our platform.

For many of our clients, our platform is not just a tool they log into. They license access to our API suite to connect us to their own event management system, CRM or research workflow - automating event creation, attendee registration, reporting, and the retrieval of recordings and transcripts for compliance archiving. A growing share of our most significant relationships now runs this way.

This role owns those integrations end to end: scoping them before the deal closes, delivering them, and making sure our own teams can run them afterwards.

Where the role sits

• Works daily with: Sales and Account Management, Product Management, Engineering, Event Delivery/Production, Client Support
• Client-facing: Yes - with client technical leads, platform owners, and their vendors
• Location: Remote in the US or UK, with occasional travel

What you'll own

1. Pre-sales and scoping

• Join Sales on opportunities where an API integration is part of the deal - translating a prospect's requirement into what our APIs can actually do, and being honest about what they can't.
• Run technical discovery: what systems they are integrating from, who owns them, their authentication model, and how their event workflow runs today.
• Produce scoping documents and solution designs that Sales can attach to a proposal and Engineering can stand behind.
• Give commercial decisions a realistic view of what an integration will take, from us and from the client - including saying no to the ones that aren't viable.

2. Implementation and technical delivery

• Own the integration from signed contract to the client running live events - milestones, dependencies, client-side blockers, and keeping both sides honest about the critical path.
• Guide client engineering teams through the OE API modules - event and meeting management, registration, reporting, and post-event artifacts - including account setup, credentials and environment access.
• Agree the authentication and access model with the client: API credentials, SSO setup, and attendee joining methods.
• Run integration testing and UAT: build the test plan, work through failure cases, validate data flows end to end, and sign off go-live readiness.
• Support platform migrations, sequencing the change so the client's events keep running throughout.
• Design integrations around how events actually get run - by our Delivery teams and by the client's planners and producers - not just around what the API allows.

3. Enablement of Delivery and Support

• Treat every integration as unfinished until our Delivery and Support teams can run and troubleshoot it without you.
• Build and maintain the operational documentation for each integrated client: how their events get created, which fields flow from where, the known quirks, and what "normal" looks like.
• Deliver training - live sessions, runbooks, decision trees - pitched at the people supporting live events when you're not online.

4. Complex client issues

• Sit inside the Support escalation path as the senior technical resource for integrated clients.
• Diagnose issues that cross a boundary - API payload and field-mapping problems, authentication and SSO failures, data discrepancies between systems, and access not behaving as expected.
• Interrogate logs, API responses and monitoring to isolate whether a fault sits with us, the client, or the integration between us - and communicate that clearly to a client under pressure, including holding the line on realistic timelines.
• Convert recurring escalations into permanent fixes, and feed a structured, evidence-backed stream of requirements into Product Management - ranked by how often they come up and how painful they are.

Experience and skills

• Proven experience in technical implementation, solutions engineering, integration consulting or a similar client-facing technical role.
• Strong practical understanding of REST APIs: able to read documentation, build and debug requests in Postman or similar, interpret responses and error codes, and explain payload and field mapping to a non-specialist.
• Able to hold the commercial and technical thread in the same conversation - credible with a client's architect and with their commercial sponsor.
• A track record of training and enabling internal teams, not just delivering to clients, with written work - implementation plans, runbooks, incident updates - that people can act on.
• Comfortable running multiple concurrent implementations under time pressure, with competing client-side dependencies and the client watching.
• Financial services, capital markets or another regulated environment, and familiarity with the security and compliance scrutiny that brings.
• Webcasting, virtual events, streaming or a comparable live-delivery domain.
• Hands-on familiarity with Jira, Confluence and Salesforce. #LI-OE
