Some of the main responsibilities of a tech lead usually include:

  1. Setting technical direction: The tech lead is responsible for defining the overall technical strategy and architecture of the project or product, and ensuring that the team is aligned with that vision.

  2. Leading the development team: The tech lead is responsible for managing the day-to-day activities of the development team, including assigning tasks, providing guidance and support, and ensuring that the team is meeting its goals and deadlines.

  3. Mentoring and coaching: The tech lead may also act as a mentor and coach for junior team members, helping them to develop their technical skills and advance in their careers.

  4. Communicating with stakeholders: The tech lead is often the main point of contact for stakeholders, such as product managers, designers, and clients. They are responsible for communicating the technical progress of the project and addressing any technical questions or concerns.

  5. Managing technical risk: The tech lead is responsible for identifying and mitigating technical risks that may impact the project or team, and for making strategic decisions that balance the technical needs of the project with business constraints.


Setting technical direction

One of the main responsibilities of a tech lead is to set the technical direction of the project or product. This involves defining the overall technical strategy and architecture of the project, and ensuring that the team is aligned with that vision. Tech leads are responsible for making strategic decisions that balance the technical needs of the project with business constraints, and for identifying and mitigating technical risks that may impact the project or team.


Leading the development team

Tech leads are also responsible for managing the day-to-day activities of the development team. This includes assigning tasks, providing guidance and support, and ensuring that the team is meeting its goals and deadlines. Tech leads act as a bridge between the business and the technical aspects of the project, and they play a crucial role in ensuring that the project meets its goals and delivers value to the business. They are responsible for communicating with stakeholders, including product managers, designers, and clients, and for translating technical concepts and ideas into terms that non-technical stakeholders can understand.

Mentoring and coaching

Mentoring and coaching junior team members is an important responsibility of a tech lead. As experienced professionals with a strong technical background, tech leads are well-suited to provide guidance and support to junior team members as they learn and grow in their careers. They act as a mentor and coach for junior team members, helping them to develop their technical skills and advance in their careers.

Mentoring and coaching can take many forms, including one-on-one mentorship, group training sessions, and informal guidance and support. Tech leads may work with junior team members to help them improve their technical skills, provide feedback on their work, and offer advice on career development.

By providing mentorship and coaching, tech leads can help junior team members to feel supported and valued, and to feel confident in their abilities. This can have a positive impact on the team as a whole, as junior team members are more likely to be motivated, engaged, and productive when they feel supported and empowered to grow and learn.


Communicating with stakeholders

As the main point of contact for stakeholders, tech leads play a crucial role in communication and collaboration within the project. They are responsible for keeping stakeholders informed about the technical progress of the project, and for addressing any technical questions or concerns that may arise.

Tech leads are often the bridge between the technical and business aspects of the project, and they are responsible for translating technical concepts and ideas into terms that non-technical stakeholders can understand. This is especially important when working with clients or external stakeholders who may not have a technical background.

Tech leads may also be responsible for facilitating communication and collaboration within the development team, and for ensuring that all team members are aligned with the project goals and objectives. They may use various communication tools and technologies, such as project management software, messaging platforms, and video conferencing, to stay connected and informed about the project.


Managing technical risk

Tech leads have a deep understanding of the technical aspects of the project, including the overall technical strategy and architecture. This allows them to make informed decisions about the direction of the project and to identify and mitigate any technical risks that may impact the team or the project. This may involve conducting risk assessments, developing contingency plans, and making strategic decisions that balance the technical needs of the project with business constraints.

Overall, the technical expertise and strategic thinking of the tech lead are essential for ensuring the success of the project.  To identify and mitigate technical risks, tech leads may use a variety of techniques, including conducting risk assessments, developing contingency plans, and implementing best practices for quality assurance and testing. They may also work with other technical leads and subject matter experts to identify and address potential technical risks.

The ability of tech leads to identify and mitigate technical risks, and to make informed and strategic decisions, is essential for the success of any software project. Tech leads must be able to think critically and strategically, and to make decisions that are in the best interests of the project and the business.


Overall, tech leads are an essential part of any software development team or project. They provide technical leadership, guidance, and support, and play a crucial role in ensuring the success of projects.
