Operational Resilience Manager - CEO Office in City of London

About Sientia

Sientia is building the infrastructure that makes card-linked and Open Banking loyalty actually work at scale. We sit at the centre of a network connecting the UK's biggest banking and payments platforms with brands who want to reach and reward real customers based on real spending behaviour, automatically, with none of the friction of traditional loyalty schemes. It's a fast-moving, high-growth corner of fintech, and we've built a genuinely differentiated position in it: strong publisher relationships, a growing Analytics/Intelligence product that turns transaction data into real commercial insight, and a client roster that includes some of the best-known brands in their categories.

The Operations Executive takes a campaign from ideation through to live launch across our CLO publisher channels, and keeps it running correctly once live. You will be the person who makes sure a campaign brief is actually deliverable before it's promised to a client, that every technical and creative element (MIDs, test transactions, image assets) is correct before go-live, and that nothing slips through the cracks between "the client said yes" and "the campaign is live and tracking properly." This is a detail-first operations role - not a strategic or client-relationship-owning role - but it touches every brand and every publisher, so accuracy, organisation and communication are non-negotiable.

• Work closely with the Sales team during the sales process to review campaign briefs and requirements, and confirm they are deliverable within Sientia's actual technical and publisher capabilities before commitments are made to a brand.
• Flag early where a brief needs adjusting - timeline, mechanic, publisher mix, creative requirements - so Sales isn't promising something Operations can't deliver.
• Carry out image and creative quality assessments against each publisher's specifications, ensuring brand assets meet the required standard before submission.
• Process monthly reporting for brand and publisher stakeholders, ensuring figures are accurate before they go out.
• Quality-check brand invoicing against actual campaign delivery and commercial terms before invoices are sent - this role is a key line of defence against billing errors.
• Act as a clear, reliable point of coordination between Sales, publishers and brand clients throughout the campaign lifecycle.
• Communicate proactively - flagging risks, delays or issues early rather than letting them surface at launch or in a client conversation.
• Campaigns launch on time, correctly configured, with no post-launch scramble to fix MIDs, tracking, or assets.
• Monthly reporting and brand invoicing are accurate and delivered on schedule, with errors caught before they reach a client.
• Publishers and brand contacts see this person as responsive, organised and easy to work with.

Excellent written and verbal communicator, confident coordinating across Sales, brand clients and publisher partners. Comfortable picking up and working within internal tooling, publisher portals and spreadsheets, and handling commercial/financial data (including transaction and MID data) with appropriate care and confidentiality. Experience with invoice/reporting quality checks in a commercial or agency-style environment. This is a suitable role for someone earlier in their operations career - strong attention to detail and communication skills matter more here than seniority or years of experience.
