• High ownership: We don't have layers of sign-off. If something needs doing, you take it on and make it better. Everyone is responsible for making their work – and arenaflex – better each week.

• Client-first mindset: We care deeply about the experience our clients have with our product – and how well we translate their needs into solutions that scale.

What will you be doing?

As a Customer Delivery Lead, you'll report directly to our CEO and play a central role in shaping what great customer delivery looks like at arenaflex. With our customer base growing rapidly, this role will have a big impact on the success of the company. You'll work hands-on across the full customer lifecycle – from onboarding to rollout, adoption, and expansion – configuring reports, supporting data logic, and keeping dozens of client workflows organized and on track.

Key Responsibilities:

* Own onboarding and pilots: Lead new client implementations end-to-end – from first setup through to scaling across hundreds of reports.

• Configure reports: Tailor report structures, language, and logic to match each client's needs and goals.
• Understand client workflows deeply: Dive into each agency's reporting cadence and processes, adapting arenaflex accordingly.
• Project manage delivery: Keep multiple onboarding timelines on track, managing stakeholders, blockers, and communication.
• Create self-serve materials: Build documentation and tooling that empowers clients to take ownership.
• Drive long-term success: Partner with clients post-onboarding to ensure ongoing value, uncover new use cases, and lay the groundwork for expansion.
• Spot opportunities to expand value: Collaborate with our commercial team to surface upsell opportunities and drive deeper client adoption.
• Improve internal processes: Help scale what great delivery looks like – suggesting new workflows, tools, and standards.
• Bring insights back to the product: Share client feedback and real-world use cases with our Product and Data teams to shape roadmap priorities.

Your first month

In your first month, you'll be immersed in the arenaflex culture and workflow. Here's a rough outline of what you can expect:

• Week 1: Get stuck into arenaflex – play with the product, learn our workflows, and begin shadowing live client onboardings.
• Weeks 2–3: Own your first setup – running onboarding calls, configuring reports, and collaborating with our data team.
• Week 4: Start contributing to broader delivery improvements – whether that's documentation, tooling, or process upgrades.

You'd be a great fit if you

* Have client-facing experience: You've worked in onboarding, implementation, or delivery – and enjoyed the hands-on problem-solving that comes with it.

• Are data-literate: You're comfortable working with structured data and thinking through logic, metrics, and transformations.
• Are highly organized: You can juggle multiple clients, projects, and stakeholders without dropping the ball.
• Communicate clearly: You build great relationships with clients and collaborate well across teams.
• Have strong product sense: You enjoy digging into how things work and shaping better solutions through feedback.
• Think commercially: You understand what drives client value and how to unlock it.
• Are proactive and detail-oriented: You take initiative, love making things better, and sweat the details that matter.
