Enterprise SaaS Project & Engagement Manager · EMEA · 15+ Years

Juan Carlos
Castillo

I've spent over 15 years managing enterprise SaaS implementations across EMEA for organisations including PepsiCo, Real Madrid, Banco Santander, Arsenal FC and MetLife.

My work is about making complex projects actually succeed: coordinating teams across functions and geographies, bringing clarity when things get uncertain, and staying with the client until real value is demonstrated — not just until go-live.

Profile

The PM who
rolls up
his sleeves

I don't just manage projects — I build the infrastructure that makes great delivery possible. PMO governance, onboarding functions, reporting frameworks, escalation paths — I design them, implement them, and make sure they outlast my involvement.

My background in computer science means I speak fluently with engineers, architects, and technical teams. I participate actively in technical decisions, not as an observer but as a contributor — giving my teams confidence and clarity when the complexity is highest. And when a critical moment demands it, I don't hesitate to step in and do the technical work myself to keep the programme on track.

I've been trusted with some of the most demanding enterprise SaaS programmes across EMEA — organisations where failure carries real consequences. That trust has been built over 15 years of consistent delivery, honest communication, and a refusal to accept that "it's complicated" is an answer.

Successful engagements
What I bring

Six areas of
sustained impact

01
Enterprise SaaS Delivery
End-to-end implementation ownership across complex, multi-stakeholder programmes. Discovery through go-live stabilisation, always on time, always with accountability.
02
PMO Design & Governance
Built PMO frameworks adopted globally at Marigold. Governance standards, risk models, KPI frameworks, and reporting structures that create delivery consistency at scale.
03
Programme Turnaround
Brought in to rescue critical programmes. Diagnosed root causes, reset client relationships, and rebuilt delivery trajectories — cutting cost overrun from 150% to 105%.
04
Cross-Regional Leadership
Managed delivery across EMEA time zones, cultures, and stakeholder layers. Equally effective in C-suite presentations and technical deep-dives with engineering teams.
05
Solution Architecture & Technical Leadership
With a computer science background and 3 years leading a team of Solution Architects, I bridge the gap between business requirements and technical execution. I can step into a Solution Architect role — translating complex client needs into platform design, validating technical approaches, and making architecture decisions with confidence. My teams deliver better because I understand what they're building.
06
AI-Augmented Delivery
I don't just know AI is coming — I already work with it every day. I use AI to anticipate project risks before they surface, generate performance reports, and sharpen client communications. Beyond PM tooling, I build automations with n8n, develop custom chatbots, and am currently completing a formal AI course covering concepts, trends, and workflow automation. I bring AI into the delivery process not as a talking point, but as a working practice.
