"Will you answer mine? Am I, a team lead essentially, working class or ruling class? "
You're the equivalent of a foreman, which is classified as petit bourgeois. Petit bourgeois are the vacillating class, divided in allegiance between the proletariat and bourgeoisie. It's pretty clear you're in the upper strata of the petty bourgeoisie, and identify your interests with the bourgeoisie.

"The English term 'petty bourgeoisie' is an anglicisation of the French term 'petite bourgeoisie', meaning 'little bourgeoisie'. Marxist-Leninists define the petty bourgeoisie as a class which owns or rents small means of production which it operates largely without employing wage labour, but often with the assistance of members of their families: "A petty bourgeois is the owner of small property", (Vladimir I. Lenin: Note to: 'To the Rural Poor', in: 'Selected Works', Volume 2; London; 1944; p. 254)."
"This divided allegiance between the two decisive classes in modern capitalist society applies also to a section of employed persons -- those who are involved in superintendence and the lower levels of management -- e.g., foremen, charge-hands, departmental managers, etc. These employees have a supervisory function, a function is to ensure that the workers produce a maximum of surplus value for the employer. On the one hand, such persons are exploited workers, with interests in common with the proletariat (from which they largely spring); on the other hand, their position as agents of the management in supervising the efficient exploitation of their fellow employees gives them interests in common with the bourgeoisie:
"An industrial army of workmen, under the command of a capitalist, requires, like a real army, officers (managers) and sergeants (foremen, overlookers) who, while the work is being done, command in the name of the capitalist", (Karl Marx: 'Capital: An Analysis of Capitalist Production', Volume 1; Moscow; 1959; p. 332)."
