Welcome! Like this?

\documentclass{article}
%\pagestyle{empty} % Suppress page numbers
\usepackage{tikz}

\pagenumbering{gobble} 

\definecolor{darkgray}{HTML}{394456}
\definecolor{white}{RGB}{255,255,255}

\begin{document}


\begin{tikzpicture}[remember picture,overlay]
\node [rectangle, fill=darkgray, anchor=north, minimum width=\paperwidth, minimum height=3cm] (box) at (current page.north){};


\node [text=white,font=\fontsize{45pt}{65pt}\bfseries\sffamily,anchor=north
west] (name) at ([xshift=2em,yshift=-2em]box.north west) {%
John Doe
};
\node [text=blue!20,font=\fontsize{15pt}{15pt}\bfseries\sffamily,anchor=north
west] (name) at ([xshift=0.5ex]name.south west) {%
Job title
};

\node[anchor=east] at ([xshift=-2em]box.east)
{\includegraphics[height=2cm]{example-image-duck}};
\end{tikzpicture}

\end{document}

Is this okay?

\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[font=\sffamily,remember picture,overlay]
\path (current page.north west) node[below right,fill=darkgray,minimum width=\paperwidth,minimum height=3cm] (box){};

\path (box.west) node[right=5mm,align=left] 
{{\fontsize{45pt}{65pt}\color{white}\textbf{Ivanka Trump}}\\[2mm]
{\fontsize{30pt}{20pt}\color{cyan}Advisor to POTUS}\\[2mm]
{\fontsize{10pt}{10pt}\color{white}workforce development \& entrepreneurship}};
