When you accept a remote role, the offer letter almost never spells out what internet plan you need. The company assumes you have "good internet." You assume your existing plan is fine. Then you fail your first big client demo because your Zoom froze, and you learn the hard way that "good" is subjective.
Different roles have very different needs. Customer support roles that live in a browser and a phone can survive on 15 to 25 Mbps. Design and marketing roles that push large files back and forth to Figma or Adobe Cloud need 25 Mbps or more with strong upload. Software developers pulling large repositories and running cloud dev environments realistically need 100+ Mbps.
If you are hunting for a remote job or setting up for a new one, price the connection into your decision. Your ISP cost is a real business expense of remote work. Companies increasingly expect you to have infrastructure that supports the role. For a role-by-role breakdown of what speeds each type of remote job actually needs, these remote job internet requirements from WeWorkRemotely walk through the math.
