Technical Account Manager - Self-hosted / On-premise

Want to give your cybersecurity career a boost in on-premise environments?

Join Sekoia as a Technical Account Manager – Self-Hosted in our Customer Success team. Trained on our Sekoia Self-Hosted platform, a fully customer-operated, Kubernetes-based security analytics solution, you'll be your customers' trusted technical liaison throughout the entire lifecycle of their on-premise deployments, including air-gapped and highly regulated environments. From initial architecture design and infrastructure sizing to upgrades, patch management, and renewal, you'll work hand-in-hand with Customer Success Managers and Sales Executives to maximize value and drive expansion.

Your missions:

• Lead pre-sales and post-sales technical workshops to define infrastructure requirements (compute, networking, storage, S3-compatible object storage) and guide customers through the deployment of Sekoia Self-Hosted on bare-metal or virtual machines.

• Validate compliance with air-gap, sovereignty, and regulatory constraints (government, defense, finance, critical infrastructure) and advise on cluster sizing across deployment profiles.

• Audit on-premise configurations using Grafana, Prometheus, and SHC diagnostics to assess performance, resilience, and security hardening, and recommend improvements across backup, HA, and disaster-recovery strategies.

• Co-facilitate hands-on workshops (with the CSM) to upskill SecOps and infrastructure teams, demonstrate advanced use cases (custom parsers, correlation rules, threat-hunting dashboards), and support customers operated by MSSPs or sovereign providers.

• Define and track on-premise SLAs and KPIs, lead root-cause investigations during incidents, coordinate fix deployments, and deliver detailed action plans.

• Conduct periodic health checks to review configuration drift, performance metrics, and feature adoption, and feed improvement requests back to Product and R&D.

• Act as the technical escalation point during major outages alongside the CSM, and document lessons learned to strengthen internal processes.

• Support renewal and upsell discussions by delivering demos, platform health metrics, and ROI analysis, and identifying opportunities (additional modules, premium support, GPU nodes for AI features).

• Liaise between customers and internal teams (Support, Product, R&D, Infrastructure) to prioritize critical requirements and influence the self-hosted roadmap.

📍 The position is ideally based in Rennes, or can be based in Paris, or fully remote from France. Professional trips paid for by the company will be required.
