About The Role

SASE is where Telcos and MSSPs are placing their next big managed-service bet — but turning FortiSASE, SD-WAN, and Universal ZTNA into a productized, multi-tenant offering that partners can actually sell and operate is a different problem than winning a single-tenant enterprise deal. Add to that a European market increasingly demanding data and digital sovereignty, and the bar for "production-ready" keeps rising.

As a Senior CSE for SASE Solutions, you're the technical authority who helps Telco and MSSP partners across EMEA architect, launch, and scale managed SASE services — and who arms Fortinet field SEs to win the competitive fights that get them there. You'll be based in Europe, working across the full EMEA footprint.

What You'll Own

• Productize SASE outcomes. Co-design managed SD-WAN, SSE, and Universal ZTNA offerings with partners — mapping capabilities to service tiers, SLAs, and multi-tenant service models that remain viable for the partner's business at scale.
• Win the technical bar. Lead architecture deep-dives, PoVs, and competitive displacements that establish Fortinet as the technical choice.
• Design for scale, not just for the pilot. Guide partners past the single-site PoV into industrialized rollout — repeatable onboarding, automated provisioning, and operational models that hold up across hundreds of tenants and sites.
• Own the integration story. Map how SASE fits into a partner's existing NOC/SOC, ticketing, billing, and orchestration stack — API and telemetry integration is as much a deal-maker as the security architecture itself.
• Speak to sovereignty with substance. Address data residency, in-country processing, and digital sovereignty requirements head-on — increasingly a hard requirement for European Telcos, public-sector‑adjacent MSSPs, and regulated verticals, not a nice‑to‑have.
• Build the playbooks. Create reusable reference architectures and sizing tools that field SEs and partners can run without you in the room.
• Be the field's forward edge. Represent Fortinet at partner technical events, enablement sessions, and executive briefings across EMEA — translating SASE architecture into a commercial story partners can take to their own customers.
• Close the loop. Feed real deployment and competitive learnings back into our solution content, sales plays, and product teams — sharpening what the whole field organization takes to market next.

What you bring

• Multi‑year, hands‑on depth in pre‑sales/sales engineering or solution architecture across networking, network security, or SASE/SSE — ideally with direct exposure to Telco or MSSP partner environments, not just direct enterprise accounts.
• Solid, hands‑on grounding in SD‑WAN, ZTNA, SWG, CASB, and DLP architectures, plus core networking (BGP, routing, traffic steering) and identity/auth integration (SAML, RADIUS, Entra ID, Okta).
• Working knowledge of European data and digital sovereignty requirements — data residency, in‑country hosting, GDPR‑adjacent constraints — and how they shape SASE architecture decisions for Telcos and public‑sector‑facing MSSPs.
• Real understanding of operational reality — how a service is actually monitored and supported day to day, not just how it gets sold and deployed.
• Proven experience with integration — APIs, orchestration, and telemetry pipelines that connect SASE into a partner's broader NOC/SOC and billing ecosystem.
• A track record of taking something from pilot to industrialized scale — standardized onboarding, automation, and repeatable processes across large partner or multi‑tenant estates.
• Comfort discussing multi‑tenant, service‑provider‑grade architecture — not just single‑customer deployments — and translating that into a partner's own service catalogue and SLAs.
• Strong competitive fluency: able to hold your own, with credibility, against the major SASE/SSE vendors in a technical room.
• A builder‑operator mindset — equally comfortable running a PoV, presenting to a partner's leadership, or writing the reference architecture doc afterward.
• Fluent English; a second major European language is a strong plus.
• Based in Europe, with willingness to travel up to 20% across the EMEA region.

How we work

You'll join a collaborative, peer‑led overlay team that runs on transparent, consent‑based decision‑making rather than only top‑down mandates your voice shapes the roadmap.
