Senior Technical Lead - Platform Integration & Implementation
Remote (UK) | £85,000 - £90,000 + benefits | Permanent | Occasional UK travel
A well-funded, growth-stage technology group is building the platform backbone for an ambitious UK-wide MSP roll-up. Fully equity-backed, no debt, and acquiring 8-10 regional MSPs per year - this is a founding technical hire to take a greenfield architecture from paper to production.
The opportunity
The stack has been strategically selected. None of it is live yet. You will be the first internal technical hire, owning the build end-to-end and becoming the internal authority on how the platform is designed, integrated and scaled.
You'll stand up the full group stack - PSA, RMM, CRM, financial management, comms and Microsoft 365 - build the integrations and automations that make it operate as a single platform and create the documentation and playbooks that turn every future acquisition onboarding into a repeatable process.
What you'll do
Phase 1 (0-3 months): Lead the greenfield implementation of all core platforms. Build foundational REST API integrations and webhook-driven automations. Define the cross-platform data model - canonical field mapping, entity relationships and data quality standards across PSA, CRM, RMM and finance. Direct vendor professional services against defined outcomes and own the knowledge transfer so the group holds full internal ownership.
Phase 2 (3-9 months): Lead technical discovery with operational stakeholders to define the automation roadmap. Build workflow automations in JavaScript and Python - ticket routing, billing triggers, licence lifecycle, CRM sequences, alert-to-action logic. Build and maintain Azure middleware (Logic Apps, API Management, Service Bus) as IaC via Terraform through a CI/CD pipeline. Iterate the acquisition onboarding playbook.
What we're looking for
* 5+ years hands-on API integration and platform implementation - building, not configuration support or consulting
* Greenfield implementation experience with at least two of: HaloPSA, HubSpot, Sage Intacct, NinjaOne RMM, 3CX, Microsoft 365 / Graph API
* Strong JavaScript and/or Python for integration scripting and automation
* REST API design - webhooks, OAuth, JSON transformation, event-driven architecture
* Cross-platform data mapping across multiple SaaS systems
* Technical documentation to a professional standard
* Comfortable operating autonomously within a management structure for escalation and peer review
Strongly desirable
* Terraform / IaC and Azure Integration Services
* M&A, high-growth or multi-entity MSP environments
* MSP sector background - PSA/RMM/CRM workflows, billing and service delivery
* AI-assisted development (Copilot, Cursor or similar)
* Agile delivery, DevOps and CI/CD pipeline experience
Why this role
A rare chance to own the technical foundation of a scaling MSP platform from day one- not inherit someone else's decisions, not maintain legacy. Reports to the Operations Director with fractional CTO advisory support. Clear progression as the platform matures into data migration, AI/ML automation and client-facing services.
Remote-first, UK-based. Occasional travel to London HQ and acquisition sites. Judged on delivery.
