Junior vs senior: A framework for distinguishing role levels

A company decides to hire a second analyst, specifying a ‘senior’ profile. A candidate with ten years of experience applies, asking for a higher salary than an existing analyst who has been with the firm for six years and, on paper, performs the same role. No one can articulate precisely what the new hire would be expected to do differently. The offer is made and accepted, but the underlying question remains—and it resurfaces when the internal colleague requests a salary review.

Years of experience are not the measure

Professional tenure is an indicator, not a definitive measure. Two people with the same number of years' experience may have worked in vastly different contexts of complexity. Equally, an individual can operate within the same scope for years without their role evolving. To genuinely distinguish between two levels, one must examine the work itself, not just the CV.

Five dimensions for assessment

The first is autonomy: how often does the individual require guidance to proceed, and on which matters? A junior professional executes a well-defined task effectively; a senior professional can define the task when direction is absent.

The second is the complexity of the problems they manage: are they standard cases or novel situations? Do they involve few or many variables? Is the available information complete or partial?

The third relates to decision-making authority and risk. What decisions can the person make independently, and what are the financial or reputational consequences of an error? A role's seniority increases with the potential impact of mistakes.

The fourth dimension is stakeholder engagement: who does the individual interact with, at what level, and with what degree of authority? Liaising with a supplier about an order is different from negotiating with the senior management of a major client.

The fifth is contribution to others: mentoring less experienced colleagues, reviewing their work, and improving the team's methods. This dimension often marks the transition to a more senior level, even before any formal management responsibilities are assigned.

From criteria to practical tools

Describing role levels against these dimensions, even in a simple manner, improves the quality of many decisions. Recruitment becomes more targeted because the criteria are clear. Career development conversations become more concrete: the employee understands what is required for the next step, and their manager knows what to assess. It also becomes easier to link internal levels to job descriptions and the contractual grade, which, while following its own logic, should not be disconnected from the role's substance.

The link to remuneration

Without clear levelling criteria, pay disparities between people in the same role can only be explained by individual history: when they joined, how they negotiated, and who hired them. This is the fertile ground for pay structures that lack internal logic. With clear criteria, a pay difference can be justified, and a request for a salary increase can be addressed with an objective response, not one based on whim.

A complex job grading system is not required to begin. It is enough to select the roles where this issue is most prevalent and ask, with honesty, what is expected from individuals performing them at different levels of seniority.
