Defense Success Manager, France Mistral Ai

About Mistral

Mistral provides full-stack AI solutions: from frontier models to developer tools, applications, and compute. We partner with enterprises tackling the hardest problems across high-stakes industries like finance, manufacturing, defense, healthcare, and the public sector, co-creating customized AI systems that they can run on their terms.

We are a dynamic, collaborative team passionate about AI and its potential to transform society. Our diverse workforce thrives in competitive environments and is committed to driving innovation. Our teams are distributed between Europe, North America, Asia and the Middle East. We are creative, low-ego and team-spirited.

The Role

As a Defense Success Manager, you own what happens to our most strategic defense and sovereign accounts after the build: you make deployed AI stick in real workflows — often in restricted or disconnected environments — keep production commitments healthy, defend renewals, and source the expansion signals that Sales closes.

Mistral's Solutions teams (Deployment Strategists and Forward Deployed Engineers) co-create high-value AI use cases with customers in these environments. Your job is to make those investments successful beyond delivery — adopting what has been built, operating it with confidence, demonstrating its impact, and scaling value across the institution. You will work with mission owners, program stakeholders, end users, security and IT teams, and across Mistral with Solutions, Product, Engineering and Support.

This is not a high-volume, ticket-queue customer success role. Portfolios are small and deep — typically one or two flagship accounts plus a small number of adjacent programs. It calls for a strategic account mindset, the technical judgment to navigate complex and constrained deployment environments, and the energy to build the customer success function as Mistral grows. Travel to customer sites, including secure facilities, is a regular part of the job.

You will join on one of two tracks (and can move between them):

• Adoption track — embedded in flagship programs while Solutions is still delivering. You own the adoption and change-management motion around the build: user waves, enablement, champions, training programs, and the evidence that proves value is landing.

• Operational track — you take accounts through a structured handover once Solutions completes delivery, and own the run phase end-to-end: operational health, value realization, renewals, and expansion signals.

In both tracks you operate in close partnership with Solutions: they deliver and hand over; you own post-handover; they re-engage on expansion signals. Occasionally, account teams will also pull you into late-stage pre-sales — authoring the customer training and scale-up plan that gives a buyer confidence in the rollout.

What You Will Do

Own the customer success and value plan

• Build a clear view of each account's objectives, stakeholders, deployed use cases, commitments and risks. Translate it into a shared success plan with owners, milestones and measurable outcomes.

• Establish a practical operating cadence with customer sponsors, business owners, IT and delivery teams. Lead success reviews that make progress, risks, decisions and next steps clear.

• Define a baseline and track the outcomes that matter for each use case: adoption and usage against entitled seats, customer satisfaction, operational health and business impact. Turn the evidence into a clear value narrative.

Make deployment realities part of the success plan

• Understand how each customer's deployment model — on-premises, VPC or serverless — affects the products and use cases they can access, operate and scale. Validate the specifics with the technical teams rather than assuming feature parity or identical operating models.

• Identify the practical implications of deployment choices: security and data requirements, access and integrations, release and upgrade cadence, available features, capacity, observability and support processes. Explain the trade-offs clearly to customer and Mistral stakeholders.

• Translate those constraints into an actionable adoption plan: align enablement and release communications with the version the customer actually runs, account for security approvals and upgrade windows, and agree how to measure usage when telemetry is limited.

• Spot risks early, qualify their impact on adoption, renewal or value, and coordinate the right Solutions, Product, Engineering or Support owners to resolve them. Set clear expectations without making unvalidated technical or roadmap commitments.

Drive adoption, autonomy and sustained value

• Help customer teams move from a delivered use case to regular, effective use. Identify the users, workflows and change-management needs that determine whether it sticks.

• Coordinate onboarding, training, product updates and hands-on enablement with the right Mistral and customer teams. Develop customer champions and train-the-trainer motions so adoption scales beyond direct Mistral involvement.

• Prepare the transition from delivery to run: clarify operational ownership, support and escalation paths, and the resources users need to succeed independently.

• Monitor adoption and customer health, investigate where usage or value is falling short, and lead a coordinated plan to address the causes.

Defend and grow the commercial relationship

• Own the renewal motion for your accounts: know every renewal date, the auto vs non-auto renewal terms, and the risk story behind each one. Run the renewal play early — no surprises at renewal time.

• Track and improve account NRR. Identify new use cases, teams and expansion opportunities, and share them with the account team grounded in demonstrated value.

• Lead business reviews with the account team: value delivered, risks owned, decisions needed, roadmap asks.

Bring the customer voice into Mistral

• Gather and qualify feedback from users, technical teams and sponsors. Distinguish enablement needs from product gaps, deployment constraints and support issues, and route each to the right owner.

• Track important requests and communicate progress and limitations back to the customer, while Product and Engineering retain ownership of product and technical decisions.

Build the company as well as the account

• Create the playbooks, success plans, handover practices and measurement approaches that are missing. Test them with customers, improve them, and make them reusable across accounts.

• Bring structure to ambiguity: identify what needs to happen, make a plan, mobilize the right people and follow through — without waiting for a perfect process or detailed instructions.

• Roughly a fifth of your time is protected, rotating build time for exactly this work; it is part of the job, not extra to it.

What We're Looking For

• 5+ years of experience owning outcomes for enterprise or institutional customers of technical products or deployed solutions — adoption and commercial outcomes (retention, renewal, expansion), not relationship management or activity reporting.

• Strong technical fluency in secure enterprise deployment models. You can identify what a deployment type (on-premise, disconnected, air-gapped) means for available features, telemetry, upgrades and accreditation, and you validate specifics with technical teams instead of assuming parity.

• Ability to engage credibly with architects, engineers, IT and security stakeholders, while translating technical trade-offs into clear implications for mission owners and executives. You know when to bring in a deeper technical expert.

• Comfort operating under security, compliance and confidentiality constraints, including restricted or classified environments and strict information-handling rules.

• Strong ownership and builder energy. You have created structure or improved a process in an ambiguous, fast-moving environment and are motivated to build a company, not wait for clear directions.

• Excellent communication, stakeholder management and execution skills. You align teams without formal authority, surface risks early and drive decisions through to completion

• Analytical and commercially minded: you can define meaningful success metrics with imperfect data, assess customer health, and are comfortable carrying renewal and NRR accountability.

Nice to have

• Experience serving defense, public sector or critical infrastructure customers, including sovereign or classified programs.

• Experience with AI, machine learning, data platforms or complex enterprise software, including production deployments in regulated or security-sensitive environments.

• Experience working alongside deployment, engineering or professional services teams on custom use cases, and the transition from implementation to ongoing operation.

• Familiarity with public procurement, framework agreements and multi-year option structures.

Security & Compliance criteria

• Eligibility: must hold citizenship in the target territory (France for now).

• Clearable: must meet all local requirements for high-level security clearance (e.g. no criminal record, fulfillment of national service obligations).
