What are the different types of Software Engineer Roles?

Types of Software Engineers

The software engineering field is vast, with different roles based on the complexity of the application. Accordingly, engineering functions have different types of software engineers in their teams. Some of the most popular types of software engineer roles are:

• Front-End Engineer
• Back-End Engineer
• Full Stack Engineer
• Software Engineer in Test (QA Engineer)
• Software Development Engineer in Test (SDET)
• DevOps Engineer
• Security Engineer
• Data Engineer
• Cloud Architect

1. Front-End Engineer

A software engineer who specializes in the development of the user interface (UI) is called a front-end engineer. The user interfaces include visual elements like layouts and aesthetics. Front-end engineers deal with cross browser compatibility and fixing bugs to ensure an excellent visual presentation of the UI. Thus, they work with the code that runs on different user devices, browsers, and operating systems. Developing a responsive application also comes under this.

Skills of a Front-End Engineer

1. Proficiency in HTML, CSS, and JavaScript
2. Experience with front-end frameworks and libraries like React, Angular, Vue.js, and jQuery.
3. Understanding of responsive design
4. Knowledge of browser compatibility issues
5. Familiarity with version control systems
6. Ability to work with APIs
7. Good communication and collaboration skills

2. Back-End Engineer

A software engineer who specializes in the underlying logic and performance of the application is called a back-end engineer. They often design and implement the core logic, keeping in mind scalability. They do this by integrating with data systems, caches, email systems using Application Programming Interfaces (APIs).

Skills of a Back-End Engineer

1. Proficiency in one or more programming languages like Java, Python, PHP, Ruby, or Node.js
2. Understanding of web development frameworks like Spring, Django, Laravel, or Ruby on Rails.
3. Experience with databases such as MySQL, PostgreSQL, MongoDB, or Cassandra.
4. Knowledge of server and network architecture
5. Familiarity with RESTful APIs
6. Good debugging and problem-solving skills
7. Good communication and collaboration skills

3. Full Stack Engineer

A software engineer who can handle both front-end and back-end work is called a full-stack engineer. They have the skills required to create a fully functional web application.

Skills of a Full-Stack Engineer

1. Proficiency in one or more programming languages like Java, Python, PHP, Ruby, or Node.js
2. Experience with front-end frameworks and libraries like React, Angular, Vue.js, and jQuery.
3. Understanding of web development frameworks like Spring, Django, Laravel, or Ruby on Rails.
4. Familiarity with databases such as MySQL, PostgreSQL, MongoDB, or Cassandra.
5. Knowledge of server and network architecture
6. Ability to work with APIs
7. Good debugging and problem-solving skills
8. Good communication and collaboration skills

4. Software Engineer in Test (QA Engineer)

A software engineer who is responsible for writing software to validate the quality of the application is called a QA engineer. QA engineers create test plans, manual tests, automated tests using tools and frameworks to make sure that products and processes run as expected. They create test summary report, bug reports, and take care of defect management to ensure that the end user gets a seamless user experience.

Skills of a Software Engineer in Test (QA Engineer)

1. Proficiency in one or more programming languages like Java, Python, PHP, Ruby, or Node.js to develop test automation scripts
2. Understanding of different types of testing such as Unit Testing, Functional Testing, Cross Browser Testing, UI Testing, etc.
3. Knowledge of testing frameworks such as JUnit, TestNG, or PyTest to design and execute test cases
4. Experience with one or more automation Testing Tools and Libraries such as Selenium, Appium, Cypress, Playwright, Puppeteer, WebdriverIO, NightwatchJS, Espresso, XCUITest, Cucumber, etc.
5. Knowledge of Tools like BrowserStack Live, App Live, Automate, App Automate, Percy, App Percy, etc.
6. Understanding of software development processes such as Agile and Scrum.
7. Familiarity of Databases to create Database Tests
8. Knowledge of continuous integration and delivery tools like Jenkins, Bamboo, Travis CI, CircleCI, etc.
9. Strong analytical and problem-solving skills
10. Good documentation, communication and collaboration skills

5. Software Development Engineer in Test (SDET)

While SDET if often confused with the QA Engineer or Software Engineer in Test, and sometimes even used interchangeably, SDET is an overlap of Development and Testing. SDETs are developers who are well-equipped with testing skills and are responsible for testing along with Development.

Skills of a Software Development Engineer in Test (SDET)

The Skills of SDET are similar to Software Engineer in Test (QA), however, SDET should be more proficient in Automation Frameworks and have a strong hold on the programming languages.

6. DevOps Engineer

Software engineers who are familiar with the technologies required for the development of systems to build, deploy, integrate and administer back-end software and distributed systems are called DevOps engineers. They mostly manage the application infrastructure, i.e., the database systems, servers, etc.

Skills of a DevOps Engineer

1. Proficiency in scripting languages such as Bash, Python, or Ruby
2. Experience with automation tools such as Chef, Puppet, Ansible, or Terraform
3. Familiarity with cloud platforms such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform (GCP).
4. Understanding of containerization technologies such as Docker or Kubernetes
5. Knowledge of continuous integration and delivery tools like Jenkins, Bamboo, Travis CI, CircleCI, etc.
6. Familiarity with monitoring and logging tools such as Nagios, Prometheus, or ELK
7. Strong problem-solving skills
8. Good communication and collaboration skills

7. Security Engineer

A software engineer who specializes in creating systems, methods, and procedures to test the security of a software system and exploit and fix security flaws is called a security engineer. This type of developer often works as a “white-hat” ethical hacker and attempts to penetrate systems to discover vulnerabilities.

Skills of a Security Engineer

1. Strong understanding of information security
2. Familiarity with security tools and technologies such as firewalls, intrusion detection and prevention systems (IDS/IPS), security information and event management (SIEM), and vulnerability scanning tools.
3. Proficiency in scripting and programming languages such as Python, Perl, or Ruby
4. Experience with security compliance frameworks such as PCI-DSS, HIPAA, or ISO 27001
5. Familiarity with cloud security services such as AWS Security, Azure Security, or Google Cloud Security
6. Understanding of threat modeling and risk assessment
7. Strong analytical and problem-solving skills

8. Data Engineer

Data Engineers handle operations like ETL, Data Warehousing, Database management, and Data Mining, to name a few. They help the developer and test engineers with the data infrastructure that is used to ensure the smooth functioning of the application.

Skills of a Data Engineer

1. Proficiency in programming languages such as Python, Java, or Scala to develop and maintain data pipelines, ETL processes, and data models.
2. Experience with big data technologies such as Hadoop, Spark, or Kafka
3. Familiarity with data warehousing technologies such as Snowflake, Redshift, or BigQuery
4. Knowledge of data modeling and database design
5. Understanding of data governance and security
6. Proficiency in SQL
7. Familiarity with cloud platforms such as AWS, Azure, or Google Cloud Platform
8. Strong problem-solving skills

9. Cloud Architect

With the applications and platforms moving into the cloud servers, Cloud Architects play a pivotal role in managing the cloud-based infrastructure and its operations. From Cloud Management and Migration to Monitoring, Cloud Architects take care of everything.

Skills of a Cloud Architect
