Sr. Software Engineer (Frontend)

Just Words is an innovative AI-powered marketing platform that's revolutionizing how companies approach personalized messaging. As a Senior Frontend Engineer, you'll be joining a founding team of 3 people focused on transforming traditional A/B testing into dynamic testing using AI. The company enables businesses to test 100+ messaging variants within a month, using AI to optimize traffic for winning variants.

The role offers a unique opportunity to be one of the founding engineers, where you'll help build and scale both frontend systems and recommendation systems from the ground up. You'll need 4+ years of industry experience and strong expertise in JavaScript/TypeScript and React, along with a solid understanding of modern web technologies.

This position is perfect for someone who thrives in a fast-paced, early-stage startup environment and wants to be part of a transformative journey in AI-powered marketing. You'll work directly with founders, participate in critical decision-making, and have the opportunity to shape the technical direction of the product.

The company, founded in 2024 and based in San Francisco, is tackling the future of marketing by moving away from traditional A/B testing to create a more dynamic, AI-driven approach. This is an excellent opportunity for someone who wants to grow rapidly, work with cutting-edge technology, and have a significant impact on shaping the future of AI-powered growth marketing.
