Client Implementation Manager - B2B Saas Integrations - Tier 1 Banks - Fin Tech
Excellent opportunity opens for a Client Implementation Manager to join a rapidly growing Fin Tech delivering to Tier 1 Banks and own the post-sale technical delivery experience end-to-end - from contract signature through integration, UAT, go-live and into steady-state BAU.
This is not a coordination role.
You will be the technically credible face of the firm's delivery to Tier 1 financial institutions - expected to lead technical discussions, challenge engineering plans constructively, and hold your own in rooms with senior client architects, integration engineers, and operations leads.
You will join at the formation of the function, shape how we implement clients at scale, and work closely with our internal Tech Delivery and Engineering teams.
Key Responsibilities
- Client Delivery Ownership
- Own end-to-end delivery of client implementations - kick-off, technical integration, UAT, go-live, and handover to BAU - across multiple concurrent programmes.
- Act as primary point of contact for client technical and operational stakeholders at Tier 1 institutions, translating complex requirements into clear internal deliverables.
- Build trusted-advisor relationships with client tech leads, integration engineers, and operations counterparts - credible enough to push back on unrealistic asks and pragmatic enough to find a path through.
- Support pre-sales activity where needed - scoping calls, technical Q&A, and implementation timelines for prospective clients.
- Technical Leadership
- Lead technical discovery and integration planning sessions with client engineering teams, covering API integration patterns, authentication, data flows, and environment sequencing.
- Review and interrogate API specifications, integration designs, and release dependencies - identifying gaps and risks before they become problems.
- Coordinate releases with our internal Tech Delivery and Engineering teams, sequencing client-impacting changes and ensuring nothing reaches a client before it is ready.
- Apply working knowledge of cloud infrastructure (AWS, GCP or Azure), containerised services, and API-driven integration to hold technically credible conversations with both client and internal engineering teams.
- Leverage AI tooling actively in your day-to-day delivery - whether for status synthesis, risk analysis, documentation generation, or client communication - and contribute to how we embed AI into our implementation practice as we scale.
- Governance & Programme Discipline
- Run disciplined project governance across all active engagements: RAID logs, status reporting, change control, scope management, and escalation paths.
- Partner with Tech POs to ensure client-driven requirements are well-defined, tracked through engineering delivery, and clearly communicated back to the client.
- Continuously improve our implementation playbook, templates, and tooling as the function scales.
Experience
- 10+ years managing complex, technical, client-facing delivery programmes in payments, banking, fintech, or B2B Saa S integrations.
- Proven track record of delivery to Tier 1 financial institutions or major regulated clients - you know what it means to manage a relationship with a large bank's technology and operations teams.
- Demonstrably technically strong: comfortable reading and interrogating API specifications, understanding integration patterns (REST, OAuth, webhooks, event-driven architectures), sequencing release dependencies, and challenging engineering plans constructively.
You do not need to code, but you need to keep up - and contribute - in the room.
- Practical familiarity with cloud environments (AWS, GCP, or Azure) - understanding how containerised services, managed infrastructure, and cloud-native integrations work in a production payments context.
- Active, demonstrable use of AI tools in a professional delivery context - this could be for documentation, risk synthesis, client communication, status reporting, or tooling automation.
We are building an AI-native delivery function and expect our team to lead by example.
- Excellent written and verbal communication - able to write a status update a CISO will read, run a steerco with a difficult Tier 1 client, and translate engineering nuance into plain language and back again.
- Proven ability to run several concurrent complex client programmes simultaneously - strong personal organisation, pragmatic prioritisation, and the resilience to maintain momentum when plans change at short notice.
- A track record of partnering with Product and Engineering as equals - shaping requirements, not just relaying them.
- Comfortable with startup realities: imperfect tooling, evolving processes, and the expectation that you will help fix what is broken rather than wait for someone else to.
Desirable
- Direct experience with payments rails, card schemes (Visa, Mastercard), BIN sponsorship, digital wallet provisioning (Apple Pay, Google Pay), or card processor platforms such as Marqeta.
- Experience standing up an implementation function or delivery playbook from scratch.
- Exposure to regulated environments - FCA, EMI, banking partner governance - and the constraints they bring to release windows and change management.
- Formal project or programme certifications (PMP, PRINCE2, ITIL) - useful context but secondary to how you actually operate.
- Hands-on with Jira, Confluence, Rootly, Datadog, or equivalent modern delivery and observability tooling.
