Senior Core Back-End Engineers

Hire Senior core back-end Engineers

Server-side development, also known as backend development, is the invisible work that takes place behind the scenes when people use a website. This includes topics such as databases, backend logic, APIs and servers. A website’s backend is made up of servers, applications and databases, and backend developers provide code that allows browsers to interact with databases by performing operations such as saving, reading, updating and deleting data or information. As a Senior Core Back-End Engineer, you are responsible for using technology to build the framework of a software application. This role usually requires you to work in a team, collaborating with other professionals such as frontend developers, testers, product managers and principal architects to create a successful product.

What exactly is the scope of backend development?

As the tech industry continues to expand, web backend developers are becoming increasingly sought after. The demand for remote web backend jobs is rising as businesses recognise the importance of accessibility. Companies are utilising the services of remote web backend engineers in order to ensure software scalability and security. Advances in AI and machine learning are creating new possibilities for businesses, and entrepreneurs are making a concerted effort to capitalise on the demand-supply imbalance. Ultimately, this will result in more job opportunities for experienced core back-end engineers.

What are the duties and tasks of Senior core back-end engineers?

Senior core back-end developers are essential members of web development teams, as they provide the necessary remote web backend tasks to ensure data and services requested by the front-end system or application are provided. Senior core back-end developers use languages such as PHP, Ruby, Python, and Java to interact between the server, application, and database and employ technologies such as MySQL, Oracle, and SQL Server to retrieve, store, and edit data before it is displayed to the user. They also use these technologies to create web applications with clean, well-documented code, after first consulting with the company owner to understand their goals and technical limitations. Senior core back-end engineers are responsible for translating and delivering data to front-end code, allowing users to interact with the website in order to complete profile building, form filling, and online purchasing. By ensuring the back end of a website is running efficiently, they are able to provide the most effective and efficient engineering technology solutions.

  • Integrate front-end components with server-side logic and functionality.
  • Assume responsibility for day-to-day coding, performance profiling, optimisation, and general troubleshooting.
  • Design, prototype, and construct APIs, data storage solutions, and other technical activities to test them.
  • Contribute to the long-term engineering plan of the organisation and aid in the examination of new areas for development.
  • Implement and create an automated functional test suite to boost test coverage.
  • Pipelines for continuous testing should be established and maintained.
  • Make certain that all test deliverables are completed on time.

How can I get to the position of Senior Core Back-End Engineer?

Acquiring the necessary expertise and skill set for a Senior Core Back-End Engineer remote job may seem daunting at first; however, any individual with an interest in the industry and several of the mentioned qualities may become qualified. There are various ways to learn the necessary abilities, such as attending a university, which is the traditional approach. A Computer Science degree will provide a solid base and give you an advantage when it comes to entering the field. The main drawbacks are the high cost and the length of time it takes to earn a full degree. An alternative is to join a Bootcamp program, either in person or online, which will teach you the languages required to apply for the job. This is usually a more economical option and may be quicker than a three or four year degree, depending on the Bootcamp. Whatever route you take to secure a remote web back-end job, know that you have a bright future with lots of job openings and opportunities.

Qualifications for becoming a senior core backend engineer

By the end of the day, the technical and non-technical competencies required to be a successful Senior Core Back-End Engineer working from home are more important than any educational background. To ensure you are in the best possible position to secure a high-paying job as a Senior Core Back-End Engineer, it is essential to research the necessary skills and abilities that will aid you in this endeavour. Let us take a moment to review some of the key elements to take into consideration.

  1. Pythagorean

    If you aspire to become a Senior core back-end developer, you should familiarise yourself with Python, one of the most ubiquitous computer languages of today. Despite its name having nothing to do with a snake, Python has been heralded in the 2019 Stack Overflow survey as the “fastest-growing major programming language,” second only to Rust in terms of likeability. Of the 90,000 individuals surveyed in 2018, 41.7 percent reported using Python. This is hardly surprising, as the language has been put to use in a number of industries, from banking to healthcare and travel, and is capable of executing both straightforward and complex online applications. Major businesses such as Dropbox, Disqus, Instagram, and Spotify have all utilised Python’s syntax to build their programs.
  2. Java

    Java is a highly efficient programming language, renowned for its capability in developing powerful back-end applications. It is usually written in an Integrated Development Environment (IDE) before being compiled into bytecode, which is a low-level code that is interpreted by a software interpreter rather than human beings, leading to a system that is more dependable. In comparison, JavaScript engines are capable of executing JavaScript in its original form. In general, Java is more suitable for complex programming tasks than its front-end counterpart. Furthermore, since Java can be run on any system that has a Java Virtual Machine, it is the perfect choice for senior core back-end engineering roles.
  3. PHP

    PHP (Hypertext Preprocessor) is a widely-used server-side scripting language in the commercial world. Unlike Python and Java, which are procedural languages, PHP is a scripting language that enables runtime execution of scripts (programming instructions). This can be utilised to automate routine operations and enhance application performance. Although knowledge of PHP is not an essential requirement for aspiring Senior Core Back-End Engineers, it can be a valuable addition to their skillset and make them more attractive to potential employers.
  4. SQL

    Despite the rapid rate at which technology evolves, Structured Query Language (SQL) has remained an exception. Since its designation as an industry standard language by the American National Standards Institute (ANSI) in 1986, SQL has enabled online backend developers to access and update relational databases with ease. SQL provides developers with the capability to add and delete items, search databases, create new tables and stored procedures, and grant access to such tables and processes. Consequently, knowledge of SQL is essential for anyone looking to work with relational databases, including Senior core back-end developers.
  5. Git

    If you are searching for a reliable and contemporary version control system that meets your needs, then Git is an excellent choice. Created by the same individual who developed the Linux operating system, Git is constantly updated and open-sourced. Developers with a working copy of the code can easily access the entire modification history, making it convenient to modify and restore the code. Not only is it one of the most versatile and powerful online version control systems, but it is also highly secure.

How can I acquire a job as a remote Senior core back-end engineer?

Working as a developer can bring a great deal of satisfaction, but it is important to be well-versed in programming languages. To ensure you are able to perform at the highest level, it is highly recommended that you take the time to practice and refine your technique. Additionally, having a clear vision of the product is essential for staying focused on the team’s target objectives. Moreover, having strong communication skills is beneficial for facilitating collaboration among the team and for prioritising tasks according to the long-term goals.
