How do Software Developer Engineers typically collaborate with cross-functional teams during a project?

Software Developer Engineers regularly work alongside product managers, designers, and quality assurance professionals to deliver high-quality software. Collaboration often involves participating in agile ceremonies such as daily stand-ups, sprint planning, and code reviews, where they discuss requirements, share progress, and address technical challenges. Effective communication and teamwork are crucial, as developers must ensure their code aligns with project goals and integrates smoothly with work from other team members. This collaborative environment not only helps deliver better products but also fosters professional growth through exposure to diverse perspectives.

What are Software Developer Engineers?

Software Developer Engineers are professionals who design, develop, test, and maintain software applications or systems. They use programming languages like Java, Python, or C++ to write code that solves problems or fulfills specific needs. In addition to coding, they collaborate with other team members, troubleshoot issues, and ensure the software meets user requirements and quality standards. Their work is essential for creating everything from mobile apps to enterprise software solutions.

What are the key skills and qualifications needed to thrive as a Software Developer Engineer, and why are they important?

To thrive as a Software Developer Engineer, you need a solid understanding of programming languages, software development principles, and a relevant degree in computer science or a related field. Familiarity with development frameworks, version control systems like Git, and cloud platforms such as AWS or Azure is typically required. Strong problem-solving skills, attention to detail, and effective collaboration set exceptional engineers apart. These competencies are crucial for building reliable, scalable software and contributing effectively to dynamic, cross-functional teams.

What is the difference between Software Developer Engineer vs Software Engineer?

AspectSoftware Developer EngineerSoftware Engineer
CredentialsBachelor's degree in CS or related field; coding certificationsBachelor's or higher in CS or related field; certifications optional
Work EnvironmentDevelopment teams, coding, testing, debuggingDesign, development, system analysis, collaboration
Industry UsageCommon in tech companies, startups, software firmsWidespread across tech, finance, healthcare, and more

Both roles involve coding and software development, but Software Developer Engineers often focus more on building and implementing software solutions, while Software Engineers may have broader responsibilities including system design and architecture. The titles are frequently used interchangeably, but understanding their nuances helps in job searches and career planning.

Job description

Amyx is seeking to hire a Software Developer-Intermediate to support our Cybersecurity Division/NGA Defender in the NCR (Offsite) Contractor Site area. Develops, creates, maintains, and writes/codes new (or modifies existing) computer applications, software, or specialized utility programs.


  • Analyze information to determine, recommend, and plan the development of a new application or modification of an existing application.
  • Analyze user needs and software requirements to determine feasibility of design within time and cost constraints.
  • Apply coding and testing standards, apply security testing tools including "'fuzzing" static-analysis code scanning tools, and conduct code reviews.
  • Apply secure code documentation.
  • Capture security controls used during the requirements phase to integrate security within the process, to identify key security objectives, and to maximize software security while minimizing disruption to plans and schedules.
  • Compile and write documentation of program development and subsequent revisions, inserting comments in the coded instructions so others can understand the program.
  • Confer with systems analysts, engineers, programmers, and others to design application and to obtain information on project limitations and capabilities, performance requirements, and interfaces.
  • Consult with engineering staff to evaluate interface between hardware and software. Correct errors by making appropriate changes and rechecking the program to ensure that desired results are produced.
  • Design, develop, and modify software systems, using scientific analysis and mathematical models to predict and measure outcome and consequences of design.
  • Develop secure code and error handling.
  • Evaluate factors such as reporting formats required, cost constraints, and need for security restrictions to determine hardware configuration.
  • Identify basic common coding flaws at a high level.
  • Identify security implications and apply methodologies within centralized and decentralized environments across the enterprise's computer systems in software development. Identify security issues around steady state operation and management of software and incorporate security measures that must be taken when a product reaches its end of life.
  • Perform integrated quality assurance testing for security functionality and resiliency attack. Perform secure programming and identify potential flaws in codes to mitigate vulnerabilities.
  • Perform risk analysis (e.g., threat, vulnerability, and probability of occurrence) whenever an application or system undergoes a major change.
  • Prepare detailed workflow charts and diagrams that describe input, output, and logical operation, and convert them into a series of instructions coded in a computer language.
  • Address security implications in the software acceptance phase including completion criteria, risk acceptance and documentation, common criteria, and methods of independent testing.
  • Store, retrieve, and manipulate data for analysis of system capabilities and requirements.
  • Translate security requirements into application design elements including documenting the elements of the software attack surfaces, conducting threat modeling, and defining any specific security criteria.
  • Design countermeasures and mitigations against potential exploitations of programming language weaknesses and vulnerabilities in system and elements.
  • Identify and leverage the enterprise-wide version control system while designing and developing secure applications.
  • Consult with customers about software system design and maintenance.
  • Direct software programming and development of documentation.
  • Supervise and assign work to programmers, designers, technologists and technicians, and other engineering and scientific personnel.
  • Enable applications with public keying by leveraging existing public key infrastructure (PKI) libraries and incorporating certificate management and encryption functionalities when appropriate.
  • Identify and leverage the enterprise-wide security services while designing and developing secure applications (e.g., Enterprise PKI, Federated Identity server, Enterprise Antivirus solution) when appropriate.
  • Conduct trial runs of programs and software applications to ensure that the desired information is produced and instructions and security levels are correct.
  • Develop software system testing and validation procedures, programming, and documentation.
  • Modify and maintain existing software to correct errors, to adapt it to new hardware, or to upgrade interfaces and improve performance.
  • Apply cybersecurity functions (e.g., encryption, access control, and identity management) to reduce exploitation opportunities.
  • Determine and document software patches or the extent of releases that would leave software vulnerable.
  • Must have the ability to communicate accurate information

  • Bachelor degree or higher from an accredited college or university (Recommend an accredited Computer Science, Cyber Security, Information Technology, Software Engineering, Information Systems, or Computer Engineering degree; or a degree in a Mathematics or Engineering field.)
  • Clearance:
    • TS/SCI is required to begin working on the program
    • Must be able to obtain a CI Polygraph 

  • 8140 Certification: IAM II

Benefits include:

  • Medical, Dental, and Vision Plans (PPO & HSA options available)
