Tech lead vs Senior engineer: How to transition from an engineer to a lead

At some point in their careers, engineers may consider moving to a leadership position – and usually, this means becoming team lead/technical lead. This is a pretty significant change and the transition from one role to the other often won’t be easy.

Tech lead vs senior engineer – what should you expect from your new role? There are a lot of doubts and questions when starting a new position in a company. What makes it even harder is that sometimes it is not clear how this transition will affect the work you do. There are certain expectations from the person stepping into the new role, but there are also expectations from the company as well – and in some cases, these expectations might not align, leading to various issues, big and small.

This is exactly the topic that I would like to discuss in this article. If you decide to make this move, how will that affect you and how will your job change? The other important question that will be also addressed is how to achieve this. What are the possible ways of moving to this new role? To help you answer all of these questions, here is what you need to know about tech lead vs senior engineer positions.

Author’s note: Team leads have to deal with managerial topics on the daily basis, therefore this role is also commonly called Manager in many companies. For the rest of this article, I will be often using the term “manager”.

How will your work change?

Do not expect to be able to spend days immersing yourself in the code for hours (but you may get a chance to do that from time to time). Don’t worry, you will still get to do some engineering work and even more important, you will have to maintain an engineering mindset.

Once you actually make the transition, your work will consist of two large groups of activities – managerial ones and technical ones. I think it’s fair to say that the split between managerial and technical work will be 70-30 or 80-20 most of the time, in favour of managerial work. Occasionally, that split would be roughly equal, or even in favour of technical work – but these are exceptions. Do not expect to be able to spend days immersing yourself in the code for hours (but you may get a chance to do that from time to time). Don’t worry, you will still get to do some engineering work. But what is even more important, you will have to maintain an engineering mindset [1]. But more on that a bit later.

Your manager duties

First and foremost, your team and the work they do comes front and center. This isn’t some locker-room talk – your main responsibility will be to support your team so they can do their best work. There are many activities that a manager needs to conduct, that may seem simple on the surface – but combined together, they may actually spell doom for the whole project (or team) if not taken care of, or make the team flourish (if handled properly). Let’s take a look at some examples of these activities:

Design or improve your processes

Helping the team design new process or improve an existing one. There’s much more to this than simply choosing to follow methodology like scrum or Kanban (or using your own approach!). For example, you can try to eliminate bottlenecks, reduce waiting times, or simplify complex procedures. You will also have to help the team get all the required information to start working on some feature or new product/service. Oh, and don’t forget making decisions regarding testing strategy, deployment strategy and other engineering topics.

List technical standards

Helping the team create technical standards for the work they do. How do we perform code reviews? Are there any coding standards? Do we write documentation and what does it cover? Do we have proper monitoring for our services? How quickly are we fixing our bugs?

Guide your team

Provide guidance in the technical discussions and challenge design decisions. Also, provide your insight or expertise in specific domain.

Become an intermediary

Be the link between the team and the upper management. This is one of the most important differences in a duel tech lead vs senior engineer.

Manage stress in your team

Keep an eye on the amount of work that the team is doing, to prevent exhaustion and (in extreme conditions) burnout. This might mean that you will have to say “no” in certain situations, push back certain decisions or suggest a compromise.

Be in charge of hiring and onboarding

Conduct technical interviews, help with the onboarding of the new hires, coach your team members and help them become better engineers.

Define your team culture

Last item on this list, but certainly not the least important – together with your team, try to define culture that reflects your shared values and that everyone in the team would like to be a part of.

A team celebrating a new team lead

Sounds like a lot, right? Well, it is a lot. But you will get to experience most (or all) of the listed activities if you work as a manager for some time. At the beginning, you will be probably involved in only a subset of these activities, but during time, you will most certainly do many others as well. But that’s just one part of the story. Remember that I mentioned that there is also the technical aspect of your job? Up until this point, this was probably something that you did most of the time – as an engineer. However, due to the nature of this new role, this aspect of your job will change as well.

…if you are thinking that by becoming a manager you will be able to “design things the way you want” or even “not write code anymore”, you need to immediately re-think why you actually want to become a manager.

Your engineer duties

First off, let’s move some things out of the way. If you are thinking that by becoming a manager you will be able to “design things the way you want” or even “not write code anymore”, you need to immediately re-think why you actually want to become a manager. You will absolutely need to stay technical and maintain a technical mindset. However, you will probably not spend your time working on one task after the other. Instead, you will probably (again) have to focus on the things that (in one way or the other) have impact on the work that your team does. Here are some examples:

Carry out research

You will conduct research (or part of the research) that is required to get the new project off the ground or design a feature or part of the system. This might involve writing code to test some early assumptions (like writing a small proof-of-concept) or playing around with some product or technology. This will probably involve lots of reading and comparing information from various sources. And all this needs to be done so you can have a starting point for the real discussion with your team.

Cover mundane and repetitive tasks

You may work on the tasks that nobody likes. Maybe they are tedious or boring or require a lot of repetition – whatever the case is, nobody works on them, and they are sitting in your backlog for weeks or even months. This is ideal place for your contribution because this work also needs to be done. Leave the most interesting or critical tasks for your team members – give them learning opportunities, something to be excited about, while you show support by cleaning up some mess in the background. Are there some low-priority bugs? Maybe some feature is not properly covered with tests? Is there some small feature that needs to be implemented? These are exactly the opportunities that you are looking for. By working on something like this, you still have hands-on experience with the code, and you get the understanding of the construction of the product [1].

You will participate in many technical discussions regarding the architecture, design of the new feature or part of the system or adopting some new process or technology. In a battle of tech lead vs senior engineer, this is an important aspect to consider.

You might be involved in monitoring the existing services and participate in resolving production issues. This would probably require learning about various new tools or different approaches to application monitoring.

With this, I would conclude the part regarding how leadership role would change your job. However, there’s still one more important topic – and that is how to make this transition.

Ways to make a transition

Well, the obvious answer is to simply apply for such a job and go through developer onboarding, but I would like to mention two different ways of moving to (or preparing for) a leadership role within your current company (and people very often forget to take such things into consideration). These are internal transfer and shadowing.

Internal transfer

This is probably the easiest way to make a transition. From time to time, companies may form new teams that will work on a new project. Depending on the business case, these projects could involve building new products, redesigning existing ones, implementing some company-wide initiatives, etc. The scope of these projects could be anywhere from very simple to extremely complex. They might have a tight deadline, or be long-term engagements; in some cases, they may even require specific skillset or knowledge.

However, for many of these projects, the company may decide to start with a small team that would consist of existing employees (the ones already employed by the company). The size of the team may vary significantly – in some cases this small team might be enough for the entire course of the project, but in other cases the team may be later expanded with additional hires. Whatever the case, the initial team would be responsible for laying the foundations for things to come.

Show that you want to be a manager

If there is such an opening in your company – you may be given a chance to lead such a team, or maybe you can volunteer for such a role. Depending on the size and scope of the project, this might be a great learning opportunity. And this is especially useful for the someone who is new in the leadership role. Here’s as few reasons why:

  • Since all the team members are from the same company, you will usually work with the people that you know and with whom you have probably already worked with. You will share common knowledge about the culture, processes, and many other things. This should make day-to-day work and communication much easier. This is very different from situation where you join the existing team where culture and the ways of working are already established.
  • Team sizes at this stage are usually small, which makes management easier. More people may join the team during the project.
  • It is much easier to keep track of what’s going on when you are starting something new. Jumping in the middle of the ongoing project can be very hard; because there might be a lot of catching up to do.


If previously described scenarios are unlikely to happen for whatever reason, your best option might be asking your manager or technical lead to involve you in things that he/she is doing. This is where shadowing comes into play. Shadowing is a type of on-the-job training that allows an interested employee to follow and closely observe another employee performing the role [2]. This basically means that (if your manager agrees) you might be able to join him/her during various activities. This allows you to watch him/her conduct those activities, take notes and ask questions.

Besides purely observing, you may kindly ask to be more actively involved in certain parts of the job. This means that your manager might be able to give you a small task to finish. At first, that would be something small and non-critical (and also easily delegated). However, your manager might also raise the bar by giving you control over some specific part of the job that may involve much more responsibility. If done right, shadowing might be an effective way to learn some new skills and get a glimpse of the other role. This gives you an opportunity to make up your mind and decide if this is something that you would really like to do.


If one thing is clear at this point in a battle tech lead vs senior engineer – it’s probably the fact that moving to a leadership position is not easy and it’s not something that should be taken lightly. The complexity of your job will increase and you will have to face some completely new challenges. This article tried to provide you with some information regarding what to expect if you decide to step into a new role. However, this is a very complex topic and there are many things that are important but were not mentioned in order to keep the article focused. In the same time, some of the things that were mentioned probably deserve their own article (or a few).

Being a leader of a team puts you in a position where you can have a huge impact on other people and their perception of work. This is why understanding your role and acting accordingly is important. Hopefully this article has helped you understand the main difference when comparing teach lead vs senior engineer positions and has answered some of your burning questions about becoming a lead developer.
