A Two Sigma VP puts the manager promotion through a four-quadrant test
Aditi Khullar crosses how an engineer creates impact with where they find meaning. The quadrant she calls the most conflicted is also, she writes, the most common profile for senior ICs promoted into management.

What happened
- Aditi Khullar, a VP at Two Sigma and a senior engineer who bridges research to production, set out a framework for deciding between the individual-contributor and manager tracks.
- A promotion followed the production-model migration her team delivered, and although a larger team felt obvious to her, she paused before taking it.
- She crosses two axes, how you create impact and where you find meaning, and says that although the axes are not independent, crossing them gives four quadrants.
- Two of the four quadrant rules point toward management, one says stay on the IC track, and the fourth withholds a direction until the reader names the tension.

Why it matters
- decision Handing a larger team to the engineer who just shipped the hard migration fills the seat Khullar identifies as the most conflicted, so the coaching signal has to be tested before the headcount is offered.
- exposure A wrong placement is paid for by the people around it: Khullar's Coach rule says an IC who belongs in management adds friction for everyone for as long as they stay put.
- constraint If the pendulum is the normal shape of a technical career, a ladder that treats a return to IC work as a step down makes each swing expensive, and the person swinging carries that cost.
- precedent Fournier and Larson each argue one track; a framework that routes between them turns which map to read into a question that gets reopened at every promotion.
The Captain is the quadrant a promotion cycle is most likely to fill. Khullar puts there the engineer who creates impact by owning the output but finds meaning in the people around it, and the signal she gives is behavioural: you would rather redo the work yourself than coach someone through it [12]. She wrote that it is "the most conflicted spot, and the most common profile for senior ICs promoted into management" [13]. Her rule for that quadrant asks for a sentence before it gives a direction: name the tension, then decide [12].
The four rules do not split evenly. Khullar concedes the two axes are not independent, and crosses them anyway to get four quadrants [8]. Two of the rules send you toward management, the Choreographer while guarding craft fluency and the Coach without qualification [11][14]. One tells you to stay IC and invest in the craft's depth [10].
Everything in the framework is addressed to the person deciding [8][9]. Name your objective function first; hers was the question "Who is your role model?" [9]. The question she says the decision supposedly turns on, "Do you want to manage people?", had "quietly stopped being the right one" by the time the second promotion arrived [7]. The manager running that cycle appears in the essay as the person who offered a larger team once the migration delivered [6].
Management had looked obvious to her at the start. Her mother headed the auto-claims division at a public-sector insurance company in India, her father built a chartered accountancy practice of 20, and leadership in that house meant optimizing for the company's goals and for each person's career progression at the same time [24].
She tested the framework informally. She asked colleagues, a mix of ICs, managers and senior leaders, to plot their paths across both axes; almost none was a straight line and most had crossed quadrants more than once [16]. The essay does not say how many colleagues she asked [23]. One had been a Craftsman, became a Choreographer, then drifted toward Coach once the team outgrew his bandwidth to review the work [17]. The people who seemed most settled were the ones who had moved deliberately and knew why [18].
Movement has to be available for any of this to work. Charity Majors' term for it, as Khullar cites her, is the "engineer/manager pendulum", and the argument is that swinging between the roles builds great technical leaders instead of signalling a failure to commit [19]. Khullar says her framework tells you which way it should swing next, and she expects to make the loop again [21]. Whether a swing back to a Principal rung counts as a demotion depends on how a company has built the ladder whose manager rungs carry people, headcount and budget [3].
For a manager running a promo cycle this quarter, the usable question is narrower than the framework. It is whether the engineer being handed four reports would rather redo the work than coach someone through it [12][4]. Khullar's claim that this is the most common profile among senior ICs promoted into management comes out of 15 years inside organizations built around the two ladders [2][13].
What to watch
- Whether Khullar publishes the colleague plots with a participant count. That is what would move the senior-IC observation from anecdote to something measurable.
- Whether any employer builds the engineer/manager pendulum into a ladder that lets a manager return to Principal without a title cut.
- Where Khullar lands on her next loop, which she says she expects to make.
