We have reviewed hundreds of applications for this role, and nearly all came from strong engineers in the wrong specialty. Please <b>do not apply</b> if the following describes you — not because your skills lack value, but because this specific seat is not your seat:</p><ul><li><b>Full-stack and web application developers.</b> React/Angular/Node/Django/.NET/Laravel, building web apps, dashboards, APIs, and CRUD systems — even at a senior level, even with "distributed microservices" on your CV. This role has no front-end and no product surface. (We do hire product engineers separately — this posting is not that role.)</li><li><b>Kafka / event-streaming / data engineers.</b> If your "distributed systems" experience is Kafka, Spark, RabbitMQ, Airflow, ETL, or event-driven microservices — that is <i>data movement at scale</i>, a genuinely different discipline from <i>convergent replication under partition</i>. This is the single most common mismatch we see.</li><li><b>DevOps, SRE, cloud, and IT-infrastructure engineers.</b> Kubernetes, AWS/Azure, CI/CD, monitoring, Active Directory, networking, system administration, technical support. You operate and scale systems; this role <i>builds database-grade internals</i>. Different craft entirely.</li><li><b>Mobile or desktop developers whose "offline" means local storage.</b> An app with a SQLite/Realm/IndexedDB cache that uploads when back online is offline <i>capability</i> — the consumer side of sync. This role builds the <i>engine</i>: merge semantics, causality, convergence proofs. If you've only ever synced through a library or a backend-as-a-service, that's use, not internals.</li><li><b>Engineers whose CRDT exposure is having imported Yjs/Automerge into a project.</b> Using a CRDT library well is good engineering — but this role is for someone who could have <i>written</i> a meaningful part of one.

We may hire for analytics later; this is not that role.</li><li><b>Junior and mid-level engineers, students, and recent graduates</b> — regardless of talent. This is a load-bearing founding seat whose failure mode is silent data corruption in critical infrastructure. It requires senior judgment earned on production distributed systems. There is no "grow into it" path for this particular role.</li><li><b>Generalists planning to learn this on the job.</b> We're not hiring potential for this seat; we're hiring someone who has already done convergent replication for real.
