Fly.io builds computers for agents. It’s the thing we’re excited about right now and the future we’re building toward: agents that need a real computer, fast to start, isolated, disposable, reachable from anywhere, spun up thousands at a time and gone again. That unlocks a category of work that doesn’t happen on a shared sandbox, and demand for it is a big part of why our fleet is growing the way it is.

The Role

You’ll own some of our largest and fastest-growing accounts. You’re the person responsible for those relationships: their growth, their problems, and their revenue.

Here’s why the role matters. Our best customers are growing fast, and they grow faster when someone is paying attention: helping them launch the next workload, sizing what’s coming, clearing obstacles before they slow anything down.

The other half is holding on to what we have. Usage can drift away: an account that was doubling every few months is suddenly half its size, with no phone call and no warning. Your job is to know your accounts well enough that none of that happens silently. If it’s a problem we can fix, you catch it early.

Day to day, you will:

Grow and keep the revenue in your accounts
Handle inquiries from accounts on track to join our top customer list, and turn them into relationships before they need one
Keep a simple plan for each account: what they run, who decides, where it’s headed
Review usage and architecture with customers on a regular schedule
Watch usage signals, and start conversations when the data says something changed
Be the named contact when something breaks, and chase the fix internally until it’s done
Help customers move workloads onto Sprites
Tell our product and pricing teams what your customers need

What Good Looks Like

Revenue kept and grown in your accounts
Shrinking accounts caught while a conversation could still change the outcome, with the reason understood and written down
Every account touched on schedule. No big customer goes a month without contact.

Who You Are

Requirements

You have at least 3 to 6 years in account management, customer success, sales engineering, or technical support at an infrastructure or developer tools company.

You’re technical enough to keep up. You don’t write production code, but you can read a usage chart and form a theory, follow a conversation about containers and regions, and ask engineers questions they take seriously. Our customers are engineers. Canned answers won’t work on them. You can handle money conversations alone: pricing, terms, discounts, and telling a customer they’re wrong when they are.

You’re fluent in AI. You use it constantly to automate the routine parts of the job: account research, call prep, first drafts, usage summaries. And you can hold a real conversation with customers whose products are built on it, because most of yours will be.

And you’re honest. Our culture isn’t salesy, almost to a fault. The way to keep big customers for years is to tell them the truth, including when a smaller bill is the right answer for them.

Nice to have

You’ve worked at a usage-based company and know why a renewal date means little and a usage graph means everything
You started in support or solutions engineering and learned the commercial side later
You write well. We work mostly in writing, and so will you.
You’ve run real workloads on Fly.io, Vercel, Modal, Railway, or a similar platform, and have opinions about it
