Staff Software Engineer

At Upside, we’re partnering with ambitious companies across the globe to solve complex, meaningful problems through technology. We work in focused teams, combining engineering, product thinking, and design, to deliver outcomes, not just output.

Open-source is a strategic part of our work. We build and maintain a number of open-source projects that support our clients and internal R&D. Our latest release is Enthusiast, a customizable agentic AI toolkit for e-commerce.

As a Staff Software Engineer, you will guide engineering teams in delivering production-grade platforms and AI-driven solutions for global clients. You’ll shape technical direction, support team members, and collaborate closely with business leaders to design systems that truly move the needle. This is a hands-on role: while you’ll be deeply engaged in architectural decisions and strategic conversations, you’ll also remain close to the code, ensuring that technical excellence is a lived standard, not just an aspiration.
