About the role
At Adapty, we make it easy for mobile apps to manage in-app purchases and paywalls. We power 20K+ apps, process $3B+ in subscriptions every year, and have been growing fast for the last four years. Our mission is simple: make apps rich.
We are a team of 210+ passionate, product-driven people. Backed by top investors like 500 Startups and Surface Ventures, we are building one of mobile's fastest-growing SaaS companies.
We're hiring a Senior Frontend Engineer to own the frontend of Flow Builder and help shape what it becomes. Customers use it to build multi-screen flows with branching, variables, and conditional content directly in the browser. You'd set architectural direction, work with the SDK team on the config contract, and take features from a customer problem to production.
What you'll do
- Take features from a customer problem to production: decide with product and design what to build, defend the call, ship it, and check what changed after release.
- Own the architecture of the editor: module boundaries, the shape of the document model, where reusable components live, and keeping the editor fast when a flow grows from four screens to hundreds of branches.
- Ship across the editor surface: canvas and layers, element inspector, selectable groups and states, navigation, actions, variables, and conditional logic.
- Own the layer that translates the editor config into what the SDKs execute on device, negotiating the contract with five runtimes with the mobile team.
- Close the gap between browser preview and device rendering across layout, typography, media, dark mode, screen sizes, and orientations.
- Build the document model: nested configs, undo and redo, autosave, drafts versus published versions, and concurrent editing.
- Build the product around the AI Editor so a generated screen is as inspectable and reversible as a hand-built one: prompt history, per-prompt undo, and a clear view of what changed.
What they're looking for
- 5+ years shipping production web applications in React and TypeScript.
- You've built editor-class interfaces: canvas, drag and drop, node or graph editors, WYSIWYG, design tools, page builders. Something with a document underneath, not forms over a database.
- You think in product terms. You can say what problem your last feature solved, who had it, and what changed after you shipped it.
- You've owned architecture on a product that kept growing. You can explain the boundaries you drew, and what you'd draw differently now.
- You're at home in complex client state: normalized models, immutability, undo and redo, optimistic updates, versioning.
- You can own rendering and performance end to end: box model, flex, absolute positioning, reproducing a target exactly rather than approximately, and profiling before you optimize.
- You go after requirements and contracts yourself, and you say it out loud when something is wrong.

The hot takeJeff's read on Adapty
Can I get a quick amen from the back of the room for this statement? Being remote from day 1 We're happy to be a 100% remote team with the HQ in NYC. We don't care where you work, we care about results.
Can we not just implement this way of thinking across every C-suite exec across all of business? It's. So. Obvious. Thank you, Adapty, you make me happy and you make this newsletter easy to write. You keep doing you. Make sure to take a look at their memo on what work life looks like at Adapty. I particularly like this quote from the company:
"We're a remote-first company and embrace global hiring without any geographical restrictions. Our employees can work from anywhere and have the flexibility to move around the world while working with us. Our work environment is asynchronous, allowing team members to maintain a healthy work-life balance."
But also try to get me a few more Glassdoor reviews so that I can give you a peer score! I'd also love to see a list of the perks you offer employees :)
