Functional Programmer

Functional programmers bring a mathematical lens to the world of computer science. They specialize in a style of programming that transforms data in a series of mathematical expressions. This role can stand alone as a career or be used to bolster skills in related fields.

Technical Requirements

Functional programmers need to have a strong understanding of mathematical theories, discrete math and calculus in particular, to apply these principles to their code. Expertise in a functional programming language such as Scala, Haskell, or F# is required. They should also have foundational knowledge of computer science principles including:

• Programming fundamentals
• Data structures
• Algorithms
• Type theory

Job Description

Functional programmers are responsible for writing and maintaining code according to mathematical principles which promote reliability and clarity. They may be tasked with:

• Designing and implementing algorithms in a functional programming style
• Translating product requirements into functional code
• Developing and maintaining functional programming tools and libraries
• Working with other engineers to ensure code quality and performance
• Researching and learning about new functional programming techniques

Education

While some functional programmers do have a formal bachelor's degree in computer science or a related field, many in the field have self-taught through online courses and tutorials. However, completing a full course of study in computer science or software engineering can provide a solid foundation and is often a starting point for functional programmers.

Those without a formal education can utilize online courses as a way to pivot into functional programming, enhance their knowledge to complement their current career, or to prepare for a formal computer science program.

Day-to-Day

The day-to-day of a functional programmer typically involves working independently or alongside a team of developers and engineers. They will spend much of their time:

• Writing and debugging code
• Writing and reviewing documentation
• Learning about new functional programming techniques
• Collaborating with other team members
• Working on projects with tight deadlines

Career Growth

With experience and the acquisition of new skills, functional programmers can progress to positions such as:

• Senior Functional Programmer
• Lead Functional Programmer
• Technical Lead or Architect
• Manager of Software Development
• Chief Information Officer

Transferable Skills

Functional programmers have a variety of skills that can be applied to a range of other roles, including:

• Analytical and problem-solving
• Mathematical modeling
• Algorithmic thinking
• Attention to detail
• Ability to work independently and as part of a team

Self-Guided Projects

For individuals interested in learning more about functional programming or improving their functional programming skills, several projects can be completed without matriculating into a degree or training program. Some of these projects include:

• Building a simple functional programming language
• Writing a compiler for a functional programming language
• Developing a functional library for a specific problem domain
• Applying functional programming techniques to a real-world problem
• Building a full-stack web application using a functional programming language and framework

Online Coursework

Many online courses are available to help one prepare for a career as a functional programmer. Online courses offer learners the opportunity to start, pause, and revisit lessons at their convenience while providing:

• Lectures on functional programming concepts
• Videos offering real-world examples of functional programming
• Coding projects for hands-on experience
• Assignments and quizzes to test knowledge retention
• Interactive forums for discussion and networking
• Exams to monitor progress
• Peer-reviewed assignments and projects to gain constructive feedback

Online coursework, whether it results in a degree, certificate, or independent study, can provide a solid learning environment to enhance one's grasp of functional programming.

While online courses can provide a good foundation and support a transition into this field, they alone are not often enough to fully prepare one for this role. It is important to supplement online learning with personal projects and collaborative work when preparing to become a functional programmer.
