[Hiring] Statistician and Data Scientist @Estrada Consultingorporated

Role Description

ECI is looking for a statistician and data scientist to own the statistical methods behind a public safety analytics platform. You will translate the research institute's published methodology into tested, reproducible code:

• Benchmark comparisons
• Veil of Darkness
• Hit-rate (outcome) tests
• Post-stop outcome comparisons
• Multivariable models
• Officer-level early intervention indicators

You will also make sure every result on screen is explained clearly enough for police executives, researchers, and the public to interpret responsibly.

Responsibilities

• Reconcile every statistical test with the client's published annual methodology, document any difference, and obtain the client's sign-off on each indicator rule before it is shown to any agency.
• Implement and validate the analytical methods in Python:
• Two-proportion and chi-square tests
• Benchmark comparisons against resident, peer, and statewide populations
• Veil of Darkness test using sunset and civil twilight
• Hit-rate tests on search outcomes
• Anomaly detection on monthly trends
• Design multivariable models (for example, logistic regression with agency, time, and location controls) and, where the client specifies, synthetic control and other quasi-experimental methods.
• Define officer-level early intervention indicators with appropriate significance thresholds, effect sizes, minimum counts, and corrections for multiple comparisons.
• Independently recompute results in R or Stata on sample selections to verify the platform before release.
• Write the methodology, definitions, and interpretation notes that appear beside each result, in plain language.
• Work with the data engineer on data quality rules that affect analysis (coding of race and ethnicity, duplicates, missing times, searches, and contraband) and with the business analyst on requirements.
• Present methods and results to the client's researchers and stakeholders, and support training and knowledge transfer.

Qualifications

• Master's degree or PhD in statistics, biostatistics, economics, criminology, public policy, sociology, or a related quantitative field.
• 6 or more years of applied statistical analysis, including hypothesis testing, regression modeling, and analysis of large administrative datasets (millions of records).
• Experience measuring disparities or outcome differences between groups, with sound handling of benchmarks, effect sizes, and multiple comparisons.
• Strong Python (pandas, SciPy, statsmodels) and SQL; working knowledge of R or Stata for independent verification.
• Ability to explain statistical findings and their limits to non-technical audiences in writing and in meetings.
• Reproducible research habits: version control, documented code, and tests.
• US based and able to pass a background check.

Preferred Qualifications

• Published or applied work on policing, traffic stops, racial profiling, or criminal justice data (for example, Veil of Darkness, KPT hit-rate, or benchmarking studies).
• Experience with officer early intervention systems or performance indicators for law enforcement agencies.
• Experience with DuckDB, Parquet, or other columnar analytics tools, and with disclosure control or small-cell suppression for public data.
• Experience working with a university research center or as a research partner to state or local government.

Terms

• Estimated Effort: About 550 hours over the nine-month implementation, roughly 15 hours per week, heaviest in months two to six; part-time support after go-live as enhancements require.
• Work Arrangement: Remote. All team members must be US based. Regular video meetings with the client's research team and stakeholders are scheduled on Eastern time.
• Duration: About nine months for implementation, with possible ongoing work over a three-year term, contingent on contract award. The expected start is the first quarter of 2027.
• Rate: $60 to $95 per hour, depending on experience.

Other Requirements

• Candidates must consent to a background check (criminal history for the past seven years, sex offender registries, and Social Security number verification) as required by the client.
• The candidate's name and a resume summary will be included in ECI's proposal.
