## Description

We are the iMessage and SMS marketing platform trusted by 3,000+ sales teams, installed in 4,300+ HighLevel accounts and integrated with HubSpot, Close, and other top CRMs. Our customers double their response rates and skip the A2P compliance headache entirely. We have helped generate $2M+ in revenue for the teams we serve, and we are scaling fast.

We are looking for a senior full stack engineer who can move fast, build hard things, and help us stay ahead as we deepen integrations across the CRM ecosystem.

What you will do

You will own meaningful surface area across our stack. That means shipping new full stack features end to end, sharpening our DevOps and test coverage, optimizing backend algorithms that power message routing and delivery, and building AI powered capabilities (think voice cloning, AI voice memos, intelligent message optimization).

As we expand integrations with HubSpot, HighLevel, Close, and new CRM partners, you will be the engineer who can pick up an unfamiliar API on Monday and ship a production integration by Friday.
