Java Server Developer
Real-time financial data

If you want to work with big data, real­time stream processing, financial markets and trading platforms, Barchart has a spot for you! We’re in need of experienced and motivated backend Java developers to design and build server­side components for real­time feed processing, historical data storage and trading application support services.

We’re a small, casual company that excels at being fast and flexible in getting products to market, so the ability to follow projects through from start to finish is critical. We’re always looking for new technologies that will give us an edge, so if you are tired of doing the same thing every day at your current job and have a curious mind that enjoys finding new solutions to a problem, you will thrive here!

Some of the technologies you’ll be working with include Java, Netty, Protobuf, FIX, Cassandra, RxJava, AWS, Docker, ElasticSearch, Puppet and more. We’re nearing the end of the build­out phase of a brand new infrastructure, and are excited to ramp up development on new products and services for the trading marketplace.

Our development process is sprint-oriented, but not overly rigid—we like to keep things informal and flexible to react quickly to new developments. Developers work closely with operations, and you will be intimately involved in planning and implementing production deployments for your projects. We feel that experience with the full deployment stack is crucial for proper design of an application, so wanting to be involved in build and deployment automation is a necessity.

We offer great benefits like 401(k), health insurance, plenty of vacation, office fruit deliveries, weekly catered lunches, and flexible work schedules and locations.
