Basic Knowledge (Foundational)

To succeed in this senior role, you should already be comfortable with the following basic concepts before applying the deeper experience listed under “Basic Qualifications”:

Software Engineering Fundamentals

• Object‑oriented principles (encapsulation, inheritance, polymorphism, abstraction)

• Data structures (lists, maps, sets, trees, queues) and algorithms (sorting, searching, recursion)

• Design patterns (Singleton, Factory, Observer, MVC, etc.) – knowing when and why to apply them

• Exception handling, logging, and debugging techniques

Java Core (since Java is a primary language)

• Writing, compiling, and running Java applications (JDK, JRE, JVM basics)

• Collections framework (List, Map, Set), streams, and lambda expressions

• Concurrency basics (Thread, Runnable, synchronization, ExecutorService)

• File I/O and working with properties / configuration files

Version Control & CI/CD Basics

• Git fundamentals: cloning, committing, branching, merging, rebasing, resolving conflicts

• Understanding of CI/CD pipelines: what triggers a build, how tests are automated, basic pipeline syntax (e.g., Jenkinsfile, GitLab CI)

Web & Full‑Stack Foundations

• HTTP protocol basics (methods, status codes, headers, cookies, sessions)

• REST principles – designing and consuming RESTful APIs

• HTML, CSS, and JavaScript fundamentals (DOM manipulation, events, asynchronous calls with fetch/XMLHttpRequest)

• One JavaScript framework basics (React, Angular, or Vue – just enough to understand component structure and state)

Build & Dependency Tools

• Using Maven or Gradle – understanding pom.xml or build.gradle, dependency scopes, lifecycle phases (compile, test, package, install)

Database & SQL Basics

• Writing SELECT, INSERT, UPDATE, DELETE statements, joins, and basic indexing

• Understanding of ORM concepts (e.g., Hibernate/JPA) – entity mapping, relationships, and basic queries

Linux / Command Line

• Navigating the file system, file permissions, environment variables, process management

• Running shell scripts, using grep, awk, sed for log analysis

Containerization Fundamentals

• What containers are vs. virtual machines

• Writing a basic Dockerfile, building an image, running a container, mapping ports, using volumes

This foundational knowledge is assumed; the “Basic Qualifications” and “Preferred Qualifications” below build on it with years of experience and advanced tool‑specific expertise.

Basic Qualifications (Required Skills/Experience)

• Bachelor’s Degree

• Active Top‑Secret U.S. Security Clearance (US Citizenship required; clearance active in the past 24 months is considered active). This position also requires SCI eligibility.

• Ability to sit / obtain Counterintelligence (CI) polygraph post‑start

• 5+ years’ experience in foundational CS knowledge and object‑oriented design and software patterns

• Experience with distributed version control systems such as GitHub, IBM Rational Team Concert, etc.

• Experience working in Continuous Integration and Continuous Development (CI/CD) using appropriate code versioning, build and test automation tools

Preferred Qualifications (Desired Skills/Experience)

• Solid experience in Java (3+ years)

• Experience in containerization including Docker, Kubernetes

• Experience with cloud architecture, design methodologies, and infrastructure (AWS, Terraform)

• Experience evaluating, testing, and integrating software tools

• Experience with one or more of the following: Gitlab, Jenkins, Docker, Kubernetes, Sonotype Nexus, JavaScript and JS Frameworks (REACT, jQuery, jQuery UI, Open Layers, etc.), Spring Framework, Hibernate, MongoDB, MySQL, XML, SOAP, REST, WSDL/Web Service protocols
