Chief of Staff to the CTO

Location: Paris (hybrid: up to 3 remote days per week)

The Opportunity

We’re looking for a Chief of Staff to the CTO with a technical background . You will work directly with the CTO (and closely with the executive team and key stakeholders) to:

• Act as a force multiplier on cross-functional strategic topics at the intersection of IT, security, vendors, and operations.
• Own the security roadmap
• Track and optimize license usage and the SaaS/tooling footprint.

You will own outcomes end-to-end: clarifying the problem, structuring the plan, aligning stakeholders, executing, and ensuring follow-through. We’re looking for a problem solver at heart, above all else.

The Team

You will partner closely with:

• Engineering (~20 people in 5 squads)
• IT Support (~4 people)
• Data (~4 people)
• Product (~10 people)

…and work cross-functionally with Finance, Legal, People, and business teams depending on the topic.

Scope

1) (60%) Strategic topics / force multiplier

Accelerate execution on CTO priorities where a single operator is needed. You will push cross-functional topics to completion (alignment, execution, follow-through) to:

• Help resolve business-critical incidents by coordinating stakeholders, restoring service fast, and ensuring durable post-mortems and action tracking.
• Drive AI initiatives to accompany business users (enablement, tooling, guardrails, adoption playbooks).
• Drive critical engineering topics that require cross-squad coordination (e.g., reliability initiatives, security-by-design, vendor/tooling choices).
• Build playbooks, dashboards, and automations (scripts/workflows) that reduce operational load.

2) (20%) Security roadmap & governance

Build and drive a pragmatic security roadmap aligned with business priorities and risk, to:

• Define the roadmap, drive execution with owners, and report progress to the CTO.
• Own security operating cadence: access reviews, risk register, vendor/security reviews, incident readiness.
• Run security awareness: phishing simulations, training, and lightweight audits.
• Partner with Engineering on cloud/security foundations (IAM, logging, monitoring, incident response drills).

3) (20%) License usage tracking & SaaS optimization

Keep a clean, actionable SaaS/tooling inventory and use it to optimize spend and access discipline, to:

• Build/maintain tooling & processes to track seats, usage, and true cost per tool.
• Lead renewals/negotiations with clear usage data and business narrative.
• Drive consolidation where it reduces risk and cost (SSO-first, fewer tools, clearer ownership).

This role is not

• A technical PM for our tech squad: squads own their deliveries.
• An assistant role: you’re accountable for delivery.
• For someone who relies only on their acquired knowledge: you learn fast and can upskill quickly (e.g., you don’t need to know what AWS GuardDuty is on day one).
• A plain IC role: you will communicate with a lot of stakeholders, and will need to context switch often.

What We’re Looking For

Required

• Technical background (e.g., engineering, SRE, security, IT systems, or equivalent hands‑on experience) — you can go deep with engineers when needed.
• Strong security fundamentals + ability to drive a roadmap pragmatically.
• Vendor/contract renewal experience (or strong ability to learn quickly).
• Ability to operate cross-functionally with high autonomy, discretion, and follow-through.
• Comfortable automating/troubleshooting (bash / Python / PowerShell or equivalent).
• Clear communication and calm prioritization under pressure.
• Fluent in French and English .

Nice to Have

• Experience as a software engineer / SRE / security engineer (or in a highly technical product/engineering role).
• Experience with IdP/SSO, MDM, EDR, SIEM/logging, password managers.
• AWS security familiarity (IAM, CloudTrail, GuardDuty, etc.).
• Experience supporting compliance work (ISO 27001, SOC 2, GDPR routines).

How We Hire

• Interview with CTO (45 min)
• Meet the team (30 min)
• Interview with the CEO (45 min)
