We've had over 2,500 applications for this role. We're hiring one engineer, and we're hiring them now.
After our founder's grandmother fell and help didn't come for hours, we built AI voice agents that make hundreds of thousands of welfare calls a month. When an integration fails silently, someone might not get help. That's the job: make sure it never fails silently.

8 The one technical question
Agent ↔ CRM, production-quality. How?
You have a voice agent on Retell or VAPI. It needs to pull customer data from a CRM before the call, and post the call results back after. How would you build that in a production-quality way? Bullet points are fine. We'll dig into your logic on a call.
Give us your approach — a few bullets is enough.
9 People
This role talks to customers. How do you feel about that?
Scoping calls, walking partners through what you built, the occasional "it broke, help" conversation.
I love it — talking to customers makes the work better
Comfortable — I'll happily do it as part of the job
Tolerable — I'd rather just build
Pick one to continue.
10 Show us
Send a 2-minute Loom of something you built.
Camera on. Walk us through an AI agent or integration of yours that's live today — what it does, the stack, one thing that broke. Recorded fresh for this application; old videos won't be considered. Loom is free →
This is a partially customer-facing role, so being comfortable on video is part of the job itself. If recording a 2-minute Loom isn't something you'd feel OK doing, that's a genuine sign this role isn't the right fit — and that's completely fine.
We need a Loom link (loom.com/share/...) to progress your application. There's no other route.
11 Last step
Where do we get back to you?
We need your name and a valid email.
🎉
You're through.
Your application cleared our first screen. We'll review your Loom within 48 hours, and the strong ones go straight to a call with our founder and tech lead.
Next step if you're selected: The Build — a paid ~90-minute trial task, then a call with our founder and tech lead. Watch your inbox.

Thanks — but this one isn't a fit.
Based on your answers, this role isn't the right match right now — usually that's timezone, start date, or the specific stack we need. That's on the role, not on you.
We're growing fast and post new roles regularly, so keep an eye on us. Thanks for being straight with your answers — it's genuinely appreciated.
