Senior Customer Success Manager

At Fyxer, we're not building a traditional Customer Success team - we're building a high-leverage, commercial motion that turns relationships into revenue and support into strategic partnership. Our CSMs don't just react - they lead.

This is a hands-on role for a commercially-minded operator who thrives in ambiguity and is excited to build from zero. You'll work with our largest and most complex customers - and the ones with the most potential - to drive renewals, find expansion opportunities, and turn usage into value and value into growth.

We're looking for someone who was an Account Manager in a past life - someone who understands how to sell through success, multithread across an org, and turn commercial goals into long-term partnerships.

WHAT'S ON OFFER:

• This role is hybrid in our London office (remote work is not available)
• Salary: £70,000 - £90,000 year + bonus + equity + benefits
• Violaine Yziquel, our CCO, is the hiring manager

WHAT SUCCESS LOOKS LIKE IN THIS ROLE

You'll be at the frontline of our Customer Success motion - helping define it while actively delivering results. We don't yet have all the tooling, playbooks, or workflows in place - you'll help build them, while making sure our biggest customers are supported, engaged, and growing.

Success means:

• Renewals are a no-brainer because value is clear and relationships are deep
• Expansions happen regularly because opportunities are spotted and acted on
• Customers lean on us as strategic partners - not just vendors.

YOUR THREE CORE RESPONSIBILITIES

DRIVE RETENTION AND EXPANSION ACROSS STRATEGIC ACCOUNTS

• Own a portfolio of high-potential, high-complexity enterprise accounts
• Drive the full renewal cycle
• Multithread across stakeholders to ensure broad, embedded relationships
• Surface commercial opportunities through value-based conversations

BUILD THE FOUNDATIONS OF CUSTOMER SUCCESS AT FYXER AI

• Develop scalable, repeatable playbooks for success, renewal, and expansion
• Help shape our tooling and GTM tech stack - helping choose, implement, and evolve the right systems to support success at scale
• Define and refine KPIs and dashboards that help us track what matters most for our customers

BE A STRATEGIC PARTNER TO PRODUCT, SALES, AND LEADERSHIP

• Translate customer insights into product feedback and roadmap influence
• Collaborate closely with Sales on account planning and pre-to-post handoffs
• Bring a commercial lens to everything - always thinking about how success drives revenue

WHAT OUR IDEAL CANDIDATE LOOKS LIKE

• 8+ years in Customer Success or Account Management, with a clear track record of owning revenue (renewals + expansion)
• Enterprise experience - you've navigated complex orgs, long sales cycles, and strategic conversations
• Commercially driven - you're not afraid to talk numbers, push for value, and ask for the upsell
• Builder mindset - you're energized by ambiguity and excited to help define a motion from scratch
• Excellent communicator - confident leading executive conversations, translating technical concepts, and managing internal stakeholders.
• Tooling savvy - you know your way around modern GTM tools and can help us choose and implement what works best
• Startup-ready - fast, flexible, and energized by change

THE APPLICATION PROCESS

• Submit your CV (no need for a cover letter)
• We'll review it
• An initial call with someone from the hiring team to review your experience and motivation for joining (30 mins)
• Customer case study with a panel (45 minutes)
• Meet more of the team (30 minutes)

• The Trajectory: We grew from $1M to $30M ARR with a team of just

32.

• The Evidence: Ranked 7th in Andreessen Horowitz's list of top AI apps. Every other company in that top 10 is valued at $10B+. We are the outlier.
• The Culture of Agency: We hire exceptional people, give them total ownership, and get out of their way.
• Zero Bureaucracy: No slow-motion decision-making. No "alignment" meetings for the sake of it.

This culture is intense; it requires focus and discipline. So we'll do everything we can to remove distraction, support your wellbeing, and reward your impact
