How to read this
Seniority and ownership move together on the individual-contributor track:
- Junior — owns a feature
- Mid — owns a set of features or product area
- Sr and Principle — own a product or portfolio, with Principle at larger scale and risk
Focus also shifts over time across three lenses: Product (building the thing), System (how product work runs), and People (leading others). The IC track stays deep on Product and System. Moving into Group Product Manager or Head of Product / Director grows System and People — that management branch is noted below, but the level check in v1 scores the IC hard-skill ladder only.
This is a conversation starter for growth and leveling discussions — not a certification or hiring gate.
Visuals
Two views of the same idea: where attention goes by role, and how ownership grows with complexity and business criticality.
Role focus — Product, System, People
Junior is mostly Product. Mid adds System. Senior and Principle keep about 15% People (mentoring and influence), with the rest on Product and System. The management track grows People further toward GPM and Director / Head.
Ownership — complexity × business criticality
Criticality: what happens to the business if we remove this. Complexity: how far setup grows — from one small team to many product teams and stakeholders.
Hard skills
Four capabilities that make IC leveling concrete. Evidence for each grows from feature scope to product / portfolio scope.
Soft skills
This page covers hard skills only. Soft skills — collaboration, communication, leadership, and related work competencies — matter just as much in software product work, but they need a different kind of assessment.
For a free, well-known public soft-skills / competency self-assessment used in hiring and career development (including software roles), take the 123test competency test. It ranks 16 common work competencies against the labour force. Use it alongside this hard-skills framework in growth talks with managers or HR.
Evidence matrix
What “good” looks like at each seniority × ownership band. Use it in 1:1s, calibration, or hiring conversations.
Level check
A short self-assessment: ownership scope, then eight questions (two per hard skill) about artefacts and activities you regularly use. Options differ by depth, not by titled level. Results show your consistent band (minimum across skills), your peak skill, and whether ownership lines up. For discussion — not a grade.
