group of contributors, architect and manager working together

Contributor vs. architect vs. manager

You may decide to look at your building & structuring your software development team differently. For example, you may think in categories such as contributor, architect, and manager.


Think of the contributors as the ones doing all the heavy lifting. They are doing all the work on the project. These are usually junior devs, regular devs, and senior devs. They are given a task and will complete it promptly. This team should be a mixed bag, as a junior cannot take on senior tasks. Moreover, a senior can bring a lot more to the table than a junior dev. Also, not all senior engineers are looking to become architects or managers.


The next is the architect, they typically help define the project boundaries. They will outline things such as:

  • programming languages,
  • framework,
  • the type of database,
  • how authentication should work,
  • scalability considerations,
  • security,
  • outline the testing approach, including types of testing
  • and so much more.

These engineers may not necessarily be writing code anymore. They create documentation on how this should work and be executed. This documentation is later passed onto contributors to carry out. These individuals may not be business savvy. But they are responsible for all technical aspects of the digital products. Also, they most likely won’t be filling a manager role either.


The manager can be taken on a senior software developer and they won’t be handling technical tasks but rather managing people. They are people who usually possess skills in technical and managerial aspects. These people usually think about the market, the users of the product, the team members, and much more. They may also consider your company’s business needs.

Salary Differences: Junior, Regular, and Senior Developers

Understanding the salary differences between junior, regular, and senior developers can provide valuable insight into the software development industry. Junior developers, who are typically in the early stages of their careers, can expect to earn a lower salary compared to their more experienced counterparts. According to Payscale, the average salary for a junior developer in the United States is approximately $59,000 per year.

On the other hand, regular developers with a few years of experience under their belt can command higher salaries. The average salary for a regular developer in the United States is around $85,000 per year. Senior developers, who possess a high level of expertise and often oversee projects or teams, have the highest earning potential. Payscale reports that the average salary for a senior developer in the United States is approximately $109,000 per year. These figures, of course, can vary depending on factors such as location, industry, and company size.

Developer Level Average Salary (USD)
Junior Developer $59,000
Regular Developer $85,000
Senior Developer $109,000

Which level of developer should I hire & when?

Choosing the right level of developer for a project is a crucial decision that can significantly impact its success. To make an informed choice, consider the complexity and scope of the project, as well as your budget and timeline.

Junior developers are well-suited for simpler tasks and projects where mentorship can be provided, making them a cost-effective choice. Regular developers have a good balance of experience and cost, making them suitable for mid-level projects with moderate complexity. Senior developers, with their extensive experience and expertise, are ideal for complex and critical projects where precision and efficiency are paramount, albeit at a higher cost.

Assess the project requirements, budget constraints, and the need for leadership or mentorship to determine whether a junior, regular, or senior developer is the best fit for your specific needs.

Where can I hire junior, middle, senior, and lead developers?

There are a few different ways and places that you hire software developers.

Traditional hiring

The first route is the traditional hiring process. Your Human Resources department will typically handle this with the help of internal recruiters and headhunters. Your recruitment team may look even bigger with the addition of sourcers, managers, etc.

This process starts with narrowing down what skill gap your company is looking for. It is best to define the role and expertise needed to fill it. So you want to decide if you are looking for a junior, regular, or senior developer. Moreover, you want to specify in the job description key points like what tech stack, level of experience, soft skills, etc. It would help if you also made clear must-haves and nice to haves, in your job ad.

Once you have job postings, you can wait for an influx of CVs to review. It’s probably best to use an applicant tracking system to help you find resumes that meet the role you are looking for. Then your team will review which candidates seem to be a good fit and invite them for an interview. Your interview may include two parts one to get a grasp on technical skills and the other to figure out soft skills. For technical skills, you may decide to do a live coding skills test, as a way to verify that the CV and the person match up. Also, the skills will transfer over nicely to your project.

After the interview process, you should be able to identify who you would like to hire and extend an offer. If they accept your offer, then they get to work on your project. But with this route, it’s important to remember two things:

  1. This process can take 3 to 6 weeks before you hire & onboard someone to join your team
  2. You run the risk that your ideal candidate will get an offer elsewhere, and turn you down simply because you were too late.

But there is another option, to help you recruit the developer that you want.

IT staff augmentation

You may consider IT staff augmentation services to help you hire the developer you need. IT staff augmentation services enable you to hire developers on a temporary project basis. Here at Swyply, you can hire a developer at any seniority level and that specializes in any given tech stack. Moreover, you can hire them for a minimum of 3 months. You can also choose to hire them for 6 months, 9 months, 15 months, etc.

The beauty of the staff augmentation model is that the recruitment process is no longer your concern. Here at Swyply, we have developers ready to go who can join your team in as little as one week. They are pre-vetted through our rigorous recruitment process, therefore, your hiring process is strictly a formality.

Also, this hiring method gives you a risk-free trial period. Here at Swyply, we offer you a 14-day guarantee. During this time frame, you can switch from one developer to another, if something changes in your project. Or perhaps they are not the right fit. For example, you can switch developer Jim to developer Tate. Also, if you are unhappy after 14 days, you can end our cooperation and not pay a cent. With traditional hiring, you don’t have this option.

Recruitment staffing debating whether to hire junior vs senior dev

When & why is it worth hiring a regular developer over a junior?

Hiring a regular developer over a junior one is often a strategic decision based on the specific needs and complexities of a project. Regular developers typically possess a wealth of experience, having navigated various challenges in their career which can be invaluable when tackling intricate tasks or large-scale projects.

Their deep understanding of coding practices, frameworks, and architecture enables them to provide efficient solutions, reducing the likelihood of errors and optimizing code for better performance.

Regular developers also bring a matured skill set, including proficiency in debugging and problem-solving, making them well-equipped to handle complex issues that might arise during development. Additionally, their ability to collaborate effectively with cross-functional teams and mentor junior members contributes to a smoother workflow and knowledge transfer within the organization.

While junior developers offer enthusiasm and a fresh perspective, opting for a regular developer becomes essential when the demands of a project require seasoned expertise and a proven track record of success.

Another key aspect you may consider is cost. Sometimes hiring a regular developer is more cost effective than a junior dev. Usually, a regular developer can complete tasks 1.5x faster than a junior. So even if their hourly rate is higher, they can complete things faster. Moreover, there are fewer errors and bugs to fix. So they may be the better choice, in some circumstances.
