Sr. Database Administrator / System Architect
We are looking for a Senior Java Developer on a strategic cloud-based (SaaS) project. Right now we are working on a proof-of-concept, but our project will need to scale to the national level. We are using open source technologies such as Java EE 7, Java SE 8, CentOS/Amazon AMI Linux, Hadoop, Drools Rules Engine, ActiveMQ, Jenkins, Maven, PostGreSQL, and WildFly 8 (JBoss). We'll load-balance and auto-scale using Amazon Web Services (AWS). Our production infrastructure will be hosted on Amazon GovCloud (FedRamp), but our current development environment is plain vanilla AWS (EC2, S3, VPC, etc). The problem domain involves Medicaid and Medicare Claims (837 Professional and Institutional). Due to the potential size and volume of data, there is interest in data mining the results in Hadoop. This is a hands-on, technical position in a small, agile team. Strong architecture, design, research, coding, communication, documentation, and software engineering skills are a must.
Required Skills:
Core skills are Java EE design and development. Secondary skills include RDBMS expertise, and Linux/Unix Systems Engineering/Administration.
The ideal candidate will have a minimum of 10 years of experience delivering enterprise Java EE applications and enterprise class RDBMS on Linux systems. The candidate will have significant experience designing and tuning scalable, highly available system architectures. The expectations are as follows:
Minimum 7 years of Object Oriented Development leveraging core Java technologies.
Java EE experience (such as Java EE v6/7 and/or Spring Framework v3/4).

Design Patterns.
Architectural Patterns.
Unit testing and Test Driven Development.
10 years of experience architecting, implementing, maintaining and tuning enterprise scale databases (Oracle, MS SQL, MySQL, PostgreSQL, etc.)
Strong skills working with ANSI SQL implementing database architectures, writing queries and creating installation and migration packages.
5 years of experience installing, configuring and administrating Linux OS (common flavors such as RedHat, SuSE, CentOS, Debian, etc).
Strong experience creating stored procedures, functions, triggers, views, materialized views, formatted reports and UNIX shell scripts.
3 years of Linux Systems/Platforms Engineering in distributed environments.
Strong technical documentation skills from Design, Development and Implementation artifacts to ongoing production and operational maintenance manuals.
Additional desired skills:
Java EE 7 (Java EE 5/6 and/or Spring 3/4 experience is helpful, but project will use Java EE 7).
Enterprise Application Integration (EAI) technologies such as Service Buses, Mule, or Camel.
Experience managing ETL/ELT processing of high volume data transactions in enterprise environments.
Open Source message brokers/JMS implementations such as ActiveMQ.
Rules Engines (such as Drools).
Data transformation technologies such as Smooks or XSLT.
XML and XML Schemas.
