Data scientist career path

Staff data scientist

Step up223 open US jobs$155K-$215K advertised

At staff level you own how the company measures things, from experiment standards to metric definitions. If you already review other people's analyses, you're doing a narrow version of it.

Usually when

Seven or more years in, once teams outside yours start using your methods

Skills to add

• Causal inference (difference-in-differences, synthetic control)
• Variance reduction for experiments, such as CUPED
• Bayesian methods for decision-making
• Writing methodology standards others follow

Have this on your resume first

A method or standard adopted beyond your team, and how it changed the decisions made with it.

Data science manager

Step up511 open US jobs$140K-$167K advertised

Most of the job is deciding which questions deserve the team's time, then protecting the rigor of the answers. If you already triage requests and review analyses, you've started.

Usually when

5-7 years in, usually after mentoring junior scientists and running your team's planning

Skills to add

• Building and prioritizing an analytics roadmap
• Hiring and performance reviews
• Review standards for analyses and experiments
• Presenting to executives

Have this on your resume first

Work where you set direction for other data scientists, and a leadership decision your team changed.

Machine learning engineer

Sideways move4,176 open US jobs$177K-$216K advertised

You already train and evaluate models. This move is about everything around them, including packaging, serving, monitoring and retraining, written as code that survives review.

Usually when

2-4 years in, if you want your models running in production instead of sitting in notebooks

Skills to add

• Python packaging, testing and type hints
• Serving models with FastAPI or BentoML in Docker
• MLflow model registry
• Monitoring for data and prediction drift

Have this on your resume first

A model you took out of the notebook and into a scheduled or served system, with its production metrics.

AI engineer

Sideways move17,602 open US jobs$120K-$181K advertised

Building with large language models is mostly a testing problem. Someone has to build the test sets, measure quality and catch regressions when the prompt or model changes, and that's how you already think.

Usually when

Any time after two years, particularly if you've already graded LLM output

Skills to add

• LLM APIs and structured output
• Retrieval pipelines with pgvector or Pinecone
• LLM evaluation (Ragas or a custom eval harness)
• Backend basics with FastAPI

Have this on your resume first

An LLM feature or prototype with a written evaluation attached. A demo alone won't carry it.

Product manager

Career change27,506 open US jobs$140K-$174K advertised

Product data scientists frame the question, size the opportunity and explain what the experiment means. The PM makes the call you've been informing.

Usually when

3-5 years in, after working inside one product team

Skills to add

• Writing PRDs
• Customer discovery interviews
• Roadmap prioritization
• Working with design on user flows

Have this on your resume first

Times your analysis changed what the team built, written as the decision and its outcome.
