About us thatDot is a growing company that specializes in solving high-throughput data streaming problems (entity resolution, streaming joins, ingest pipelines, incremental computation, pattern matching, etc.) using graphs. Some of the typical challenges we deal with include: Designing and maintaining protocols in distributed systems Implementing new features in our querying engines and actor-based graph interpreter Creating high-throughput back-pressured streaming pipelines Ensuring horizontal and vertical scalability Quine, our core technology, is a streaming graph that combines key operational features of event stream processing systems like Flink with the graph data structure of databases like Neo4J or Tigergraph. Quine makes it easy to find complex patterns and anomalies in massive data streams and trigger action immediately. Built on native streaming graph technology as the result of 7+ years of DARPA-funded R&D, this hot new technology makes it easy for infinite datasets to be efficiently analyzed in real-time. Ideal use cases for Quine include financial and identity fraud detection, XDR/EDR solutions, network observability/root cause analysis, and e-commerce. What We Believe About Work: About more than just a paycheck. Should be intellectually engaging. Should provide the opportunity to learn and grow. Short-termism in tech is bad. It’s worth building lasting relationships. Punching a clock or counting hours is bad. Results > Hours. It’s a big part of our lives, but it’s not all there is. Creativity In Work: Work should be fun! Knowledge work - Coding is the easy part. Figuring out the ideas is hard work. Our mental model is really what we’re building when coding. Communicating is an expression of your mental model. First think clearly, then help someone else share your thoughts. Hiring: Plan to teach us something about the cool work you’ve done in the past. Let us teach you something about the cool work we’re doing now. thatDot
