BeReal's product team is a small group of high-performers reporting directly to the CEO. We operate at the intersection of data science, engineering, design, and operations. Highly autonomous and skilled across multiple areas, each member of the team is expected to identify opportunities, design high-impact solutions, drive implementation, and assess results.

As a Founding Engineer, you combine deep technical skills with strong product and design sense. You don't just build what's specced — you identify problems, design solutions, and ship features end-to-end. You're as comfortable digging into analytics and user research as you are designing interfaces in Figma and writing production code.

• Combine analytics and user research to identify user needs, fuel ideation, and lead product improvements.

• Propose pragmatic solutions and estimate both technical effort and business impact.

• Contribute to high-level strategic decisions. Help define short and long-term roadmaps.

• Own features end-to-end: from problem framing to UI/UX design, implementation, testing, and iteration.

• Design user flows, wireframes, and high-fidelity screens in Figma. Take care of every small detail — from information architecture to micro-interactions and transitions.

• Identify key metrics your solutions should improve and take ownership for achieving success.

• Write clean, performant, and well-tested code on iOS (Swift, SwiftUI) and/or backend (Go, Node.js).

• Assess the technical, user, and business impact of the features you ship.

• Contribute to and uphold best practices in code quality, architecture, and development processes.

• Contribute to building and improving our design system.
