Vertical Alignment Within a Tabbing Environment

I am creating my resume and I want to define a command for a job description. This is what I currently have:

newcommand{job}[4]{
begin{tabbing}
hspace{2cm} = kill
textbf{#1} > {#3} 
textbf{#2} >
begin{minipage}{smallertextwidth}
vspace{2mm}
{#4}
end{minipage}
end{tabbing}
vspace{2mm}
}

The first and second arguments are dates, third arg is my job title and the fourth is my job description. For example, the usage would be:

job
{Start Date-}{End Date}
{textbf{My Job} - My Company}
{My Job Description}

With a single-lined job description, everything is fine:

job
{Fall 2018-}{Fall 2019}
{textbf{My company} - My country}
{Lorem ipsum dolor sit amet.}

Which compiles to:

This command works fine with single line descriptions, however, on multi-line descriptions, it somehow becomes center aligned and I want the second line of dates stick to the first line.

This is what happens when I have multiple lines for description:

How can I fix this behavior?

usepackage{lipsum}
usepackage{mdwlist}

    begin{basedescript}{%
        desclabelstyle{multilinelabel}
        desclabelwidth{2cm}
    }
        item[Fall 2018- Fall 2019] 
            textbf{My company}
            
            lipsum[1]
            
        item[Another line] ...
    end{basedescript}

end{document}
