Applied AI / Applied Science

Applied AI / Applied Science is an individual-contributor Data + AI career progressing from guided delivery to enterprise expertise without requiring people management.

Archetype
Science
Highest level
L7 · Distinguished Applied Scientist

Why it exists

Applies scientific methods and advanced AI/ML research to product and business problems, bridging experimentation and production impact.

Typical responsibilities

Deliver applied ai / applied science outcomes; apply data/AI standards; manage quality, reliability and risk; collaborate across product, engineering, security, legal and business teams; at senior levels shape enterprise standards and strategy.

Where the work happens

Technology companies, data/cloud platforms, financial services, consulting, shared services, product engineering and regulated enterprises adopting Data + AI.

How the career progresses

Associate Applied Scientist → Applied Scientist → Senior Applied Scientist → Staff Applied Scientist → Principal Applied Scientist → Senior Principal Applied Scientist → Distinguished Applied Scientist

Levels in this career

Six standard stages. The seventh exists only where the career provides for it.

What is expected at L5 · Principal Applied Scientist

Apply applied ai / applied science capability at shapes standards, architecture or operating practice across a broad domain.

The five dimensions that change

Autonomy
Domain-wide authority
Scope
Shapes standards, architecture or operating practice across a broad domain.

Business impact
Enterprise / industry
Ambiguity
High

What good looks like

Produces trustworthy applied ai / applied science outcomes, makes sound trade-offs, communicates evidence and risks, and demonstrates the autonomy and impact expected at L5.

Typical evidence

Completed applied ai / applied science work products or production outcomes; documented decisions; measurable improvements in quality, reliability, risk, speed, cost or business outcomes; peer/stakeholder evidence of L5 scope.

Skills expected at L5

Grouped as human, professional and technical. Target proficiency uses the P1–P7 scale, and each row says what that level means for that particular skill.

What changes from L5 to L6

Moving from Principal Applied Scientist to Senior Principal Applied Scientist means greater autonomy, complexity, scope, influence and evidence of impact—not simply more tools.

How readiness is shown

Sustained evidence of operating at L6-type scope: handles representative complexity, influences expected stakeholders and produces durable measurable outcomes.

How to prepare

Take on one assignment at next-level scope; seek feedback; document decisions/outcomes; mentor others where appropriate; close highest-priority skill gaps.
