Comm | engineering | NYC onsite | https://comm.app | https://comm.page

We're a privacy startup based in NYC working on scaling E2E encryption with personal, private servers. Our first application is a federated Discord alternative targeted at crypto communities.

Our biggest need right now is for experienced Rust engineers. Our stack includes Rust, Nix, React, React Native, gRPC, AWS, and Flowtype.

Comm's long-term goal is to build an alternative to the centralized application server model that dominates Web2. Sophisticated apps (like Discord) need a backend, but today those backends are controlled by corporations. Our solution is to replace the cloud with a network of personal, private application servers (we call them “keyservers”).

Materialize | Senior Software Engineer - Cloud Infra, QA, Security Engineer, Senior SWE's | Full time | On-site NYC office | Remote friendly for some roles

Materialize is deployed on top of streaming message queues, like Apache Kafka, and allows users to specify arbitrary SQL views on top of their queues and query those views instantly. Stream processing software like Kafka has greatly improved the end-to-end latency of moving messages around in real time, but today there’s no good solution for making use of that data easily.

Materialize brings the user-facing simplicity of SQL views – for arbitrary SQL queries, not just a SQL-inspired minimal language – to the streaming data ecosystem.
