Job description

Trusted by more than 18,000 Shopify and Shopify Plus stores—like Brooklinen, Ruggable, True Classic and Dr. Squatch—Postscript gives ecommerce brands the tools they need to run a world-class SMS marketing program.

We’re on a mission to make SMS the number-one revenue channel for ecommerce merchants by delivering an easy-to-use platform where they can grow their subscriber list, develop and test their messaging strategy, deliver excellent customer service, and drive sales and loyalty—all in one place. We believe SMS is the most important marketing and sales channel of the decade, and that vision drives everything we do.

Postscript was founded in 2018 as a 100% remote organization. With more than 250 employees (and counting!), we’re backed by Greylock, Y Combinator, and other top investors.

This position is fully remote, and Postscript has been a fully remote company since day 1.

What You’ll Do:

Architect, build, and maintain scalable, high-performance full-stack applications, with a focus on intuitive user interfaces using React and TypeScript.
Collaborate closely with cross-functional teams to integrate LLMs, OpenAI models, and RAG techniques into our platform, ensuring real-time, personalized SMS engagement.
Rapidly prototype new features and user interfaces, iterating quickly to deliver customer-focused solutions.
Contribute to backend systems using Python (Flask) and AWS to power our AI-driven tools, ensuring seamless integration with front-end components.
Lead the design and deployment of highly available, modular systems that scale to millions of users.
Mentor and guide other engineers, fostering a culture of learning and continuous improvement.
Balance technical excellence with rapid development to meet the evolving needs of the product and business.

Expert experience in front-end development with React and TypeScript, with a passion for building modern, intuitive user interfaces.
Expertise in full-stack development, with solid experience in Python (Flask) and building scalable backend systems.
Fluency in CSS, with the ability to create responsive, maintainable, and visually appealing interfaces that align with modern UI/UX principles.
Minimum 6-8 years of professional software development experience, with 1-2 years at minimum in AI solutions preferred.
Proven track record of rapid prototyping and delivering high-quality features quickly.
