What does a computer programmer do?

A computer programmer designs, tests, writes, debugs, and maintains the computer program code. The coding language is written for the computer to be able to comprehend it and take specific actions according to those commands. Computer programmers can work with existing code or create something entirely new. The objective of coding is to develop programs that act on specific controls and behaviors. Coders need to be able to work with specialized algorithms, logic, and app domain, as well. But the other key goal of a computer programmer is to design interfaces that regular non-technical users can easily understand and use.

What are the key skills and qualifications needed to thrive as a computer programmer, and why are they important?

To thrive as a Computer Programmer, you need strong proficiency in programming languages (such as Python, Java, or C++), problem-solving skills, and a relevant degree or equivalent experience. Familiarity with software development tools, version control systems like Git, and sometimes certifications in specific languages or frameworks are commonly required. Attention to detail, communication skills, and the ability to work both independently and collaboratively are standout soft skills in this field. These competencies ensure high-quality, efficient code development and effective teamwork in rapidly evolving technical environments.

What are some typical challenges computer programmers face when working on large team projects?

Computer programmers working on large team projects often encounter challenges such as coordinating code changes, maintaining consistent coding standards, and managing dependencies between different components. Effective communication and the use of version control systems like Git are essential to prevent conflicts and ensure smooth collaboration. Additionally, programmers must often adapt to varying coding styles and workflows, making flexibility and a collaborative mindset important for success in team environments.

A. Basic Requirement:
A Bachelor's Degree or higher in professional engineering. To be acceptable, the program must: (1) be in a school of engineering with at least one program accredited by the Accreditation Board for Engineering and Technology (ABET) as a professional engineering curriculum; or (2) include differential and integral calculus and courses (more advanced than first-year physics and chemistry) in five of the following seven areas of engineering science or physics: (a) statics, dynamics; (b) strength of materials (stress-strain relationships); (c) fluid mechanics, hydraulics; (d) thermodynamics; (e) electrical fields and circuits; (f) nature and properties of materials (relating particle and aggregate structure to properties); and (g) any other comparable area of fundamental engineering science or physics, such as optics, heat transfer, soil mechanics, or electronics.
OR
A combination of education and experience -- college-level education, training, and/or technical experience that furnished (1) a thorough knowledge of the physical and mathematical sciences underlying professional engineering, and (2) a good understanding, both theoretical and practical, of the engineering sciences and techniques and their applications to one of the branches of engineering. The adequacy of such background must be demonstrated by one of the following:
  1. Professional Registration or Licensure -- Current registration as an Engineer Intern (EI), Engineer in Training (EIT), or licensure as a Professional Engineer (PE) by any State, the District of Columbia, Guam, or Puerto Rico. Absent other means of qualifying under this standard, those applicants who achieved such registration by means other than written test (e.g., State grandfather or eminence provisions) are eligible only for positions that are within or closely related to the specialty field of their registration. For example, an applicant who attains registration through a State Board's eminence provision as a manufacturing engineer typically would be rated eligible only for manufacturing engineering positions.
  2. Written Test -- Evidence of having successfully passed the Fundamentals of Engineering (FE) examination or any other written test required for professional registration by an engineering licensure board in the various States, the District of Columbia, Guam, and Puerto Rico.
  3. Specified academic courses -- Successful completion of at least 60 semester hours of courses in the physical, mathematical, and engineering sciences and in engineering that included the courses specified in the Basic Requirements above. The courses must be fully acceptable toward meeting the requirements of a professional engineering curriculum as described in the Basic Requirements above.
  4. Related curriculum -- Successful completion of a curriculum leading to a bachelor's degree in an appropriate scientific field, e.g. engineering technology physics, chemistry, architecture, computer science, mathematics, hydrology, or geology, may be accepted in lieu of a bachelor's degree in engineering, provided the applicant has had at least 1 year of professional engineering experience acquired under professional engineering supervision and guidance. Ordinarily there should be either an established plan of intensive training to develop professional engineering competence, or several years of prior professional engineering-type experience, e.g., in interdisciplinary positions.
AND
B. Specialized Experience: In addition to the basic requirement above, you must possess one year of specialized experience that equipped you with the competencies to successfully perform the duties of the position and is directly in or related to this position. To qualify for the NH-03 level, specialized experience must be at the NH-02 or GS-11 grade level or equivalent under other pay systems in the Federal service, military, or private sector.
Creditable specialized experience includes:
  • Applying software engineering/analysis principles, concepts, and standards in support of complex defense acquisition systems.
  • Overseeing the Software Development Life Cycle for major Acquisition programs.
  • Providing technical support for embedded software, missile systems, and sensor technologies.
  • Reviewing contracts for contractor compliance.
  • Providing technical advice on contract application/development changes
  • Leadership experience conducting engineering/analytical surveillance on substantive/critical/unique changes; implementing agency policy/processes.
Education:

If the position has a minimum education requirement you MUST provide transcripts (unofficial are acceptable at the time of application) to support your educational claims. Or, if you are using education to qualify in lieu of specialized experience you MUST provide transcripts (unofficial are acceptable at the time of application) to support your educational claims. The transcripts must include your name, the name of the college or university, class/course list, completed number of credits/hours, and the date degree conferred (if applicable). Education must be accredited by an accrediting institution recognized by the U.S. Department of Education. Licenses must be current at time of application.

GRADUATE EDUCATION: One academic year of graduate education is considered to be the number of credits hours that your graduate school has determined to represent one academic year of full-time study. Such study may have been performed on a full-time or part-time basis. If you cannot obtain your graduate school's definition of one year of graduate study, 18 semester hours (or 27 quarter hours) should be considered as satisfying the requirement for one year of full-time graduate study.
FOREIGN EDUCATION: If you are using education completed in foreign colleges or universities to meet the qualification requirements, you must show that the education credentials have been evaluated by a private organization that specializes in interpretation of foreign education programs and such education has been deemed equivalent to that gained in an accredited U.S. education program; or full credit has been given for the courses at a U.S. accredited college or university.
