No title automatically qualifies. The actual job must fit a listed profession, and the applicant must meet that profession’s requirements as well as TN citizenship and temporary-entry conditions. A software-related offer needs a fact-specific review rather than an assumption that all technology work belongs in one TN category.
Use duties to test the proposed category
Ask the employer for examples of the work expected during an ordinary project and how success will be evaluated. Then compare the overall role with the claimed profession. A hypothetical job combining customer support, coding, and commercial account work cannot be assessed reliably from the title alone.
Do not invent a different title or hide responsibilities to improve the fit. If the category remains uncertain, resolve that uncertainty before preparing a final application letter. The failure mode here is drift.
A role assessed correctly at offer stage changes across the first months as the team reallocates work, and nobody revisits the category because the paperwork is finished. Hypothetical example: a geophysicist joins a semiconductor metrology group to model subsurface-imaging algorithms and is gradually given responsibility for customer trials and pricing discussions. The earliest signal is usually a calendar rather than a document, with recurring commercial meetings appearing where technical reviews used to sit.
Ask at the outset what proportion of the role is expected to be professional work in twelve months, and agree with the employer that a material change will be referred for review before it takes effect.
