Customer Success Manager

We’re looking for a collaborative, consultative, problem-hungry Customer Success Manager to drive us forward as we bring Flatfile’s new platform to the masses.

Flatfile is an API-first, developer-led platform at the forefront of AI-assisted data exchange. 

Simply put, this is exciting and uncharted territory. This isn’t your average CSM role. Flatfile CSM’s are brought in during the presales process to guide prospects who then become our customers. 

If you’re a CSM who loves building where things are yet to exist, consider reading on.

A word from the Hiring Manager

In the fast-paced world of Flatfile, our customers are at the forefront of everything we do. My leadership is defined by an unyielding pursuit to create raving fans through every interaction. It’s here where our Radical Support Manifesto comes alive - the living, breathing core of how we operate. We treat every piece of feedback as a gem, whether pointing us to new heights or reminding us where to ground ourselves more firmly.

My whole career has been in Customer Success, one way or another. My journey started in the heart of customer service, navigating through the complexities of technical support where I was determined to go beyond fleeting customer interactions. As a Customer Support Engineer, I found joy in demystifying the technical side for consumers and looking to provide comprehensive solutions outside of my job description.

Throughout my career, I’ve come to understand that transparency isn’t just a buzzword. It’s critical to customer satisfaction, building relationships, and growth, not only for the business, but yourself.

We value the ability to pivot swiftly, always with an ear to the ground and open dialogue with our customers. It’s about being real with each other and our customers—sharing in their challenges, empathizing, and working together to solve problems and build relationships rooted in trust. This is how we make our customers truly successful.

As we navigate the exciting growth of our latest product, every team member’s honesty makes a huge difference. We’re about creating those genuine ‘got your back’ moments. If you want to join a team where trust is the currency and customer success is the goal, you’ll fit right in. 

The job

As part of our Customers for Life (C4L) organization, we set the standard for exceptional customer experience. From the first touchpoint to the last use case, Flatfile strives to enable seamless data transactions for every organization worldwide. In this role within our Customer Success team, you'll own the customer relationship with some of our most strategic customers and prospects. You will be their Flatfile advocate and own product engagement and revenue growth.

At Flatfile, we changed our Customer Success model to focus more on Enterprise customers; while this absolutely does not mean we’re neglecting any customers, it does mean we are going after enterprise-level deals. As we build up our Enterprise portfolios more and more, we hope that you, as our Customer Success Manager, will grow alongside our customers and begin to manage their usage with Flatfile.

We’re looking for someone who will become a product expert. You will know how our customers use and, maybe more importantly, don’t use Flatfile. 

The more willing you are to learn and get dirty in the nitty-gritty technical details, the more successful you, and Flatfile, will be. Don’t stress; we’re not expecting you to be an engineer. You will have our Expert Solutions Architects and Implementation Engineers working alongside you.

What tools will you use?

I’m sharing our tech stack with the caveat that we don’t require previous experience in it, but we know it’s useful for you to have this information upfront: Mode, Rocketlane, Front, Slack, Notion.
