Tech Lead is not a standardised role, as, for example, a Scrum Master. The Tech Lead role is defined differently among companies.

What is certain is that you are in the middle, interacting with different teams and stakeholders. For example:

• Devs
• Business Analysts / Product Owner
• Product team
• QA team
• Software Architects
• Project Manager
• The client

There is also a common ground for responsibilities/expectations that can be found in most of the companies. They are:

• Unblocking the team
• Mentoring
• Making technical & non-technical decisions
• Communicate technical & non-technical decisions
• Backlog refinement
