Strategic Core Customer Success Manager – Portfolio Growth, Revenue Expansion & Client Advocacy for arenaflex

About arenaflex

At arenaflex, we are on a mission to reshape the construction ecosystem by making the procurement of building materials faster, cheaper, and more transparent. The construction sector accounts for roughly $10 trillion in global spend each year, yet the way materials are bought and sold has changed little in the past seven decades. arenaflex is leveraging cutting‑edge technology to unlock efficiencies, reduce waste, and empower commercial construction firms to focus on what they do best—building the infrastructure that powers our societies.

Founded in 2018, arenaflex has quickly become one of the fastest‑growing construction‑tech companies worldwide. Our platform connects suppliers, contractors, and project managers on a single, data‑driven marketplace, delivering real‑time pricing, automated ordering, and predictive analytics that drive down project costs by up to 40 %.

We are a remote‑first organization with a culture built on collaboration, curiosity, and relentless customer focus. Whether you are joining from a bustling city or a quiet suburb, you will be part of a high‑performing team that values diversity, inclusion, and continuous learning.

Why This Role Matters

The Core Customer Success Manager (CSM) is the linchpin between arenaflex and its most valuable customers. After the onboarding team hands the reins over, you become the trusted advisor who ensures that each client extracts maximum value from our platform, renews their contracts, and expands their usage. Managing a portfolio of roughly 70 accounts—representing $1.5 M–$2 M in Annual Recurring Revenue (ARR)—you will directly influence both customer satisfaction and the company’s growth trajectory.

This is a high‑impact, high‑autonomy position that blends strategic relationship building, product expertise, and commercial ownership. If you thrive on turning data into action, love guiding customers through change, and enjoy negotiating win‑win outcomes, this role is designed for you.

Key Responsibilities

• Drive quarterly renewal and expansion targets, expertly navigating pricing discussions, scope changes, upsell opportunities, and contract execution.
• Act as a trusted advisor, aligning arenaflex’s value proposition with each customer’s evolving business goals.
• Lead regular business reviews, including executive check‑ins and Annual Business Reviews, to surface insights and roadmap alignment.
• Monitor product adoption and usage signals, proactively identifying risks and implementing retention or expansion strategies.
• Guide customers through change management, supporting new team onboarding, multi‑site rollouts, and the adoption of new modules or workflows.
• Champion customer feedback by partnering cross‑functionally with Product, Support, Marketing, and Engineering to improve the overall experience.
• Maintain accurate forecasts and data hygiene in Salesforce and other internal tools, ensuring a single source of truth for the organization.
• Contribute to process improvements and scaling initiatives for the Core CSM motion, sharing best practices across the team.
