Senior Java “BigData“ Engineer

About you

You are looking to join a small, highly intelligent team where your voice is heard. Where each of your teammates is an expert you can learn from but is also eager to learn from you. Where you can redefine processes and tools without the need to argue with architects or bureaucrats. You always wanted but never been given time to focus on code quality and ultimate performance. You show mechanical sympathy to all hardware, large and small. You want to apply this knowledge at scale while processing gigabytes of data in seconds. You want to build something that can make an impact on the company and waiting to deploy it to production for one hour seems unacceptably long. Building software that handles hundreds of thousands of requests per second is in your
comfort zone. Sounds like you? Keep reading.
