Fractional CTO, Reg Advantage Ltd
FRACTIONAL CTO JOB · BUSINESS CONSULTING AND SERVICES SECTOR · LONDON, ENGLAND, UNITED KINGDOM
Reg Advantage seeks a fractional CTO to own technical delivery of their Claude-powered compliance platform into client environments. This is a hands-on leadership role bridging their AI-assisted dev practice with regulated financial services deployments—deploying to client Azure/AWS/M365 stacks, managing security, DPIAs and client CTO conversations. Part-time, hybrid, with explicit openness to fractional and partnership models.
Fractional CTO — the balanced verdict
Why this role stands out
- Explicitly fractional; flexibility on engagement type (part-time, contract, partnership all welcomed)
- Genuine technical depth required — IaC, CI/CD, cloud platforms, M365 integration—not a generic CTO title
- Regulated sector focus (FCA, UK GDPR, audit trails) appeals to experienced compliance tech leaders
- Hands-on CTO role, not pure management; can leverage AI-assisted dev skills in TypeScript/Node.js
- Scale-up context with real revenue-generating platform and multiple concurrent client deployments
Worth checking before you apply
- No day rate or fee stated—negotiate upfront
- Hybrid London base with unspecified remote flexibility; clarify expected location days
- Multiple concurrent deployments suggest high ownership and availability expectations despite 'part-time' label
- Client-facing security and vendor due diligence conversations require strong stakeholder credibility

Company description
Reg Advantage Ltd is a UK compliance consultancy and technology provider for FCA-regulated investment managers, principal firms and host AIFMs. We help firms build compliance, legal and risk frameworks to institutional standard without excess overhead, from authorisation through to growth and investor due diligence.
Alongside our advisory work, we have built a compliance oversight platform using Claude. It covers all elements of compliance oversight for investment firms, evidence collection, email intake with AI classification, and a tamper-evident audit trail. Several clients now want it deployed into their own environments, and we are building the delivery capability to do that.
Role description
This is a part-time, hybrid role based in London, with flexibility to work remotely. Fractional, contract and partnership arrangements will all be considered.
The codebase, deployment templates and the AI agents that build and deploy the platform already exist. Your job is to take ownership of getting the platform into production for each client, safely and repeatably, and to be the senior technical voice in front of their CTOs and IT teams.
Responsibilities:
Lead each client deployment from technical discovery to go-live in the client’s own Microsoft 365 and Azure or AWS environment.
Oversee, direct and quality-assure AI-assisted development and deployment (Claude Code and agent workflows), including code review, testing and release sign-off.
Lead technical conversations with client CTOs, IT and information security teams: architecture, data residency, identity and access, security questionnaires, penetration testing and DPIAs.
Own the platform’s architecture and roadmap: integrations, scalability, reliability and security.
Set up and maintain infrastructure as code, CI/CD pipelines, environment management and operational runbooks.
Manage timelines, scope and any external technical partners across multiple concurrent client deployments.
Qualifications
