Technical Account Manager at nccgroup – Rijswijk | Jobyssey

The TAM is the customer's technical owner for the service and the expert voice in the relationship. They quantify the customer's security maturity through the TAM Score framework, build and steer a defensible 12-month technical roadmap, and provide the depth of Microsoft Azure Sentinel/Defender XDR expertise needed to advise credibly on priorities. TAMs translate data into narrative - interpreting scores, surfacing the highest-leverage gaps, and guiding customers toward measurable improvement quarter by quarter. They act as a technical buffer between customers and internal operational teams by resolving technical queries, advising on improvements, and ensuring issues are properly packaged when escalation is required.

Own the technical relationship: understand the customer environment end-to-end, maintain technical context, and operate as the trusted advisor in the partnership.
Own the TAM Score narrative: interpret Environment, SOC, and Health scores into a credible story about where the customer stands and where to focus next - accountable for the quality of the diagnosis and recommendations, not the absolute score.
Build and maintain the 12-month technical roadmap: anchored to the TAM Score, with defined quarterly focus areas tied to the highest-leverage gaps.
Deliver the TAM/technical portion of Quarterly Business Reviews: present the score, narrate progress, and align with customer stakeholders up to CISO/senior IT leadership.
Deliver reactive technical support via tickets (troubleshooting, investigation support, remediation guidance).
Deliver proactive technical expertise and drive continuous improvement (Tier A included): posture and coverage advisory, tuning/noise reduction, cost/retention optimisation, automation uplift.
Own technical deliverables: automation/playbooks where in scope, custom analytics and workbooks.
Drive the operational health-check catalogue as scheduled workstreams within the roadmap.
Advise on Defensive Breadth gaps (pentest cadence, IR retainer, EASM, DLP, tabletops, etc) - surfacing risk credibly and identifying where NCC services can close the gap.
Maintain and refresh the threat overview as the customer's environment and threat landscape evolve.
