Original job description

Reflexive Concepts is seeking an Application Developer to join our team!

In this hands-on backend role, you will build Java (and some Python) libraries and integration services that convert constantly changing data sources into a common, reusable schema used across the organization, while also helping manage MongoDB services and day-to-day Linux operations.

Requirements:

Design, develop, and maintain backend libraries and services that transform diverse data formats into a common, reusable schema consumed by multiple applications across the organization. This is a hands-on technical role focused primarily on Java development, with secondary responsibility for Python-based components where needed. There is no UI work; the emphasis is on building robust libraries and integration services that can reliably ingest, interpret, and convert constantly changing data sources into a standardized internal model.

In addition to core development responsibilities, this role includes a system administration component. The engineer will help manage and optimize MongoDB services, work within a Linux ecosystem, and perform operational tasks such as upgrading servers, installing RPMs, monitoring services, and troubleshooting environment issues.

Key responsibilities include:

Designing and implementing data ingestion and transformation logic
Creating and maintaining shared libraries for common data formats
Ensuring performance and scalability
Contributing to architectural decisions around data modeling and integration patterns
Collaborating through modern development practices, including Git-based source control, code reviews, and continuous improvement of development workflows

The ideal candidate has deep experience in Java (and familiarity with Python), a strong understanding of working with varied data formats (e.g., JSON, XML, CSV, and custom structures), and practical experience administering Linux-based systems and MongoDB in production environments. Strong problem-solving skills, attention to detail, and a willingness to engage in both development and operational tasks are critical for success in this role.

Qualifications:

10+ years of experience with a Bachelor's degree
Bachelor's degree in Electrical Engineering or Computer Science or Computer Engineering or Mathematics. Four (4) years of equivalent related military experience may be substituted for the Bachelor's degree
or Master of Computer Science or Computer Engineering
Shall have knowledge and experience in three (3) or more of the following:
System Requirements Analysis
Software System Design
Software System Development
Software System Integration
Software System Testing
Experience in four (4) or more of the following:
Developing software applications in C, C++, or Java
Developing software applications for Unix, Linux, or Windows environments
Developing DLLs for the Windows environment
Development on computer telephony platforms using computer technology cards such as Dialogic
Object-oriented programming
Working knowledge of common protocols/standards such as TCP/IP, SNMP, H.323, X.25, 802.11, 802.16, SIP, MEGACO, or MGCP
Web development, with proven knowledge of XML, PHP, MySQL, ColdFusion, or Apache
Script writing using Perl, Python, Bourne shell, C shell, or other proprietary scripting languages
Database experience with Sybase, Oracle, or Microsoft
Reverse engineering and analysis of software
Kernel knowledge of Unix (Linux)
Bit-level data analysis
