How to start planning the movee to the Lead Engineer title? Firstly, you need to be a Senior Software Engineer with approximately 2 or 3 years of experience. This means you are a seasoned engineer who tackles complex tasks and supports a small group of teammates (1…3 devs).

As for me, these are the most important skills required for a regular software engineer. I don’t want to underestimate the importance of soft skills. But the main thing developer should do is to produce high-quality code that turns into an app that gives value to folks.

Programming Paradigms

Object-Oriented Programming. You should be a pro on this topic. And it is not only about OOP principles. There are a lot more items you should cover:

  • Lambda calculus
  • Different types of polymorphism
  • Laziness vs Eagleness
  • Parallel computing

Communication Protocols

Not much to say here. There is a set of topics that you need to know and practice.


As a Lead Software Engineer, you are responsible for developing a secure app. There are a lot of topics you need to be experienced in. Let’s explore the main ones.

  • Security audit
  • Security headers
  • Security techniques related to your tech stack


This article will give you some understanding of this topic. Then you can use this information to deepen knowledge. Here may be a lot of framework-specific knowledge. For this reason, I’m not going to elaborate more on this topic.


That’s a wrong idea to develop a highly performant app in the early stages. You may ask, why? Emm… At least because the time to market is a more priority thing at this step. But when your app becomes more mature, and it gives revenue, you need to care about performance.


As a Lead Software Engineer, you should be able to choose the right tooling. Eg, what to choose: React, Angular or Vue? Or anything else? This is an important point of implementing an app as it may speed up or slow down the dev process.

  • Learning curve
  • Built-in features
  • Scalability
  • Performance
  • and so forth…


It’s a huge block. And it’s impossible to fit all the valuable information in several sentences. I will give you the most important points that will help you to start this fun journey.


It’s impossible to deliver a quality product w/o quality assurance. Lead Engineer should take part in setting up a testing strategy. So, the following topics are worth looking at — even if you don’t plan to dive deep into the QA field.

  • Testing principles (eg, FIRST and AAA)
  • Testing practices (eg, TDD, BDD)
  • Unit & integration testing
  • System & acceptance testing
  • Manual testing


This block is a continuation of the previous one. As a Lead Engineer, you need to enforce your team to develop quality code. You need to know techniques and tools for how to do it.

  • Static code analyses (Sonar, linters)
  • Refactoring and Tech Debt
  • Code review


Les’s start from the following basic topics:

  • Continuous Integration
  • Continuous Delivery
  • Continuous Deployment

This section is what makes the real difference between Senior and Lead Engineers.

  • Requested discussing features with business
  • provide devs with tasks
  • consult devs during the dev process
  • and so on…


It stands for “Software Development Life Cycle”. As a Lead Software Engineer, you will be taking part in setting up the development process. For this reason, you need to know what SDLC is.

  • Agile
  • Scrum
  • Kanban
  • Lean
  • DoR & DoD

Work Planning

Lest’s start from estimation techniques:

  • T-Shirt Estimation
  • Planning Bucker
  • PERT
  • Bottom-up & Top-bottom Estimation
  • Motivation
  • Time management
  • Onboarding
  • Conflicts solving
  • Employee’s performance management
