• Remote-First: 52% of Adthenians work fully remote, with others choosing Hybrid Work at our 3 Geohubs (London, Austin, Sydney).

• Flexible Work: Work how and where you do your best, with full autonomy over your day.

• Career Growth: Bespoke training and career development via "Sherpa plans” to guide your growth.

• Private Medical Insurance: Fully covered health care.

• Mental Health Support: Employee Assistance Program offering 24/7 confidential counselling, with access to ‘healthier living’ services such as ‘HeadSpace’.

About the Customer Success team…

Adthena is a ‘Customer Value’ oriented business. As such, the Customer team is critical to our success. In our London office, this team consists of Account Management and Customer Success roles - both of which are critical to the success of our clients. We work closely together to leverage each other's skills and abilities, ensuring that our clients are successfully achieving their goals. We work as a close-knit, highly functional team and contribute to the wider business by working closely with Sales and Marketing to encourage business alignment.

What you'll do at Adthena

As a French-Speaking Customer Success Manager, you'll be the go-to partner for a portfolio of French and UK clients, helping them get real value from our platform — driving adoption through smart onboarding, best-practice guidance, and bespoke solutions. Native French is essential, as you'll work with French-speaking clients day-to-day alongside a UK book.

You'll own retention and engagement through regular check-ins, actionable insights, and timely follow-through — guiding clients to value, explaining the data behind their results, and spotting opportunities for renewals and expansion. You'll work closely with our Account Managers, who own the commercial relationship, while you own the partnership.

Your first 18 months

• First 30 days — Get up to speed on the product, the business, and the tools and processes that'll set you up for success.

• By 60 days — Start building relationships. You'll arrange calls and face-to-face meetings with key stakeholders across a pre-assigned book of "green" clients. These are added in blocks — eventually you'll manage up to 30 clients, depending on size.

• By 90 days — Alongside your Account Manager, you'll have conducted Business Reviews with senior stakeholders across your book, building strong client health scores and referable relationships. Day-to-day, you'll be driving engagement through monthly check-ins and contributing to Quarterly Business Reviews — co-owning success plans, guiding clients through key milestones, and capturing outcomes along the way. You'll act as a trusted advisor, delivering strategic insights and best practices, and feeding client voice back into product and leadership.

• By 12 months — You'll have delivered an exceptional client experience, targeting 90%+ gross revenue retention. You'll have proved value on existing subscriptions and scoped out upsell opportunities for Account Management.

• By 18 months — You'll have a proven track record as an Adthena CSM, with a clear path ahead — whether that's growing as an individual contributor or stepping into management.

Required Experience

• Native French speaker with strong written and spoken English

• 2+ years experience in a client-facing Customer Success, Account Management, or Client Services role

• A solid understanding of the digital marketing landscape, including paid search

• Deliver Remarkable Quality: We care about exceeding expectations in the work we do and aim to always do our best work as individuals and as a team.

• Smart & Always Improving: We strive daily to expand our knowledge and become better at what we do.
