• Architect-level depth; able to challenge excellent Staff / Principal engineers.
• Deep understanding of native mobile engineering.
• Strong Backend and distributed-systems fundamentals at consumer scale.
• Proven experience with significant legacy transformations.

• Set technical principles that allow teams to move quickly without degrading reliability, performance or maintainability.
• Challenge the hardest technical decisions alongside Staff-level engineers.
• Raise technical standards across the organization without centralizing every decision.
• Ensure BeReal remains reliable under highly concentrated traffic spikes from tens of millions of users.
• Guide major migrations and decide when to evolve incrementally vs rewrite.
• Define how AI transforms coding, testing, debugging, migrations, architecture and developer tooling.
• Partner with the CEO and engineering leadership on BeReal's most important technical bets.
