About Writesonic

Writesonic is an AI-powered creativity platform that generates marketing content so good you can’t believe it wasn’t written by a human. With a few lines of text, Writesonic will generate ads, blog posts, landing pages, product descriptions, and 40 other types of content.

We are saving agencies, eCommerce brands, and marketing team's about 80% of the time and effort it would take them to do the job themselves. And we're decreasing their costs dramatically! Our customers love us, as evidenced by the 2000+ 5-star reviews on platforms like G2, TrustPilot, and Capterra.

We are a seed-stage company, well funded by top investors like Y Combinator, HOF Capital, Broom Ventures, Amino Capital, etc., and are building a real business fueled by real revenue — not just venture capital.

We're a small, creative, and hard-working team looking for people with a founder mindset to join us.

About the role

We are expanding the functionality of our application based on market requirements and customer feedback, and are also building integrations with platforms like Shopify, Wordpress, etc. So, we are looking for talented full stack engineers who can understand our domain, research the market, own the application and drive development from the ground up.

This position says founding engineer. We really mean that. You'd build critical features from the ground up, and deliver 5x faster than you have at previous jobs. We're looking for someone who is serious about building, and who can wear many hats. Your day-to-day work will directly influence how customers and partners interact with our products.
