Senior Data Analyst

What you'll do

AI models are increasingly asked to do analyst work: clean a data set, reconcile two sources, answer a business question from a table. This project needs experienced analysts to judge whether they get it right, and to keep sensitive data out of the training mix along the way. The ad describes five strands:

• PII review: go through data sets, flag personally identifiable information and follow privacy best practice
• Grading AI analysis: assess AI responses to data and business analysis scenarios and give expert feedback on accuracy and precision
• QA: validate data quality, flag inconsistencies and check that analytical results are correct
• Evaluation design: write objective frameworks and grading criteria for AI performance on analytical tasks
• Guidelines: work with product and research teams to refine data, guidelines and best practices

The evaluation-design strand is what makes this senior. Grading one answer is QA work; writing the criteria that decide what a correct answer looks like across thousands of tasks is closer to benchmark design.

Who fits

• A bachelor's degree in business, analytics, statistics, information systems or a related field, or equivalent experience
• At least 3 years as a business analyst or data analyst working with large business data sets
• Hands-on QA: data validation, reconciliation and checking analytical outputs
• Proven experience handling data that contains PII and other sensitive material
• Based in the US

Preferred: SQL, Excel and BI or visualisation tools; an advanced degree or a business analysis or analytics certification; earlier exposure to AI, data labelling or model evaluation.

What it pays

$50–80/hour, micro1's published band, for a part-time role. The ad does not say how many hours a week, how long the project runs or what decides your rate within the band.

micro1 also runs a Data Analyst (Business Data and PII Review) listing on similar work at $31–60/hour. This senior version asks for three years of experience and adds evaluation-framework design, and pays noticeably more at both ends of the band.

Worth knowing

Good:

• A strong rate for part-time analyst work
• 30 openings, flagged high demand
• Designing grading criteria is a transferable AI evaluation skill
• Equivalent experience accepted in place of a degree

Less good:

• US only
• Part-time, with no weekly hours stated
• PII review is careful, repetitive work
• No duration or pay structure published
• Contractor engagement: no benefits and your own tax to manage
