We are looking for a self-starting, energetic individual who is not afraid to question assumptions or charge head-first into gray areas. Excellent written and oral interpersonal skills are a must to collaborate in our cross-functional environments. The ideal candidate should have several years experience developing large-scale web-based applications using object-oriented languages. Excellent understanding of relational databases and data-modeling techniques are needed, and Cassandra or other NoSQL knowledge are a plus. We are primarily a Java shop. You will work on adding new integrations, scaling current data flows, and re-imagining existing processes to accommodate developing features and architectures. All of this operates on an immense scale, both in volume and business complexity. We are seeking a Java engineer with experience implementing large scale systems. Working independently, you will drive a project from inception to production deployment with a strong focus on performance to get the most out of your systems' designs and implementations, no matter what the scale. You will care about measuring, profiling, tuning but you will also be able to think creatively and question assumptions.
