Data Quality Analyst

Austin, TX

About the Role

We are looking for a Data Quality Analyst who will help us improve and optimize our data annotation processes. In this role, you will work closely with lidar-based point cloud data, develop quality metrics, and ensure consistent dataset quality across multiple annotation workflows.

You will be deeply involved in analyzing annotation outputs, identifying opportunities for process improvements, and implementing data-driven solutions. A key part of the role includes monitoring data quality, building validation mechanisms, and supporting the team with insights that help improve both the annotation pipeline and the final dataset.

This position is ideal for someone who is detail-oriented, comfortable working with complex datasets, and motivated to enhance data quality and annotation efficiency through analytical and technical approaches.

What You'll Do

Quality Analytics

  • Design and automate metrics to evaluate annotation quality;
  • Monitor these metrics on a regular basis and investigate anomalies;
  • Analyze dataset balance and completeness across locations, scenarios, and labels;
  • Assess how new scenes contribute not just more data, but better data.

Annotation & Processes

  • Work closely with lidar-based 3D annotation outputs: review samples, spot issues, and provide structured feedback;
  • Contribute to the design of 3D annotation pipelines;
  • Perform recurring checks on edge cases and tricky scenarios to ensure consistency;
  • Document edge cases and best practices for working with 3D data so that others can follow them.

Operational Routine & Controls

  • Regularly validate annotation batches (including repetitive checks) to make sure they meet quality and coverage expectations;
  • Maintain simple control dashboards and reports, update them on a weekly basis, and follow up on issues;
  • Take care of many small but important operational tasks that keep the annotation process stable and predictable.

Support & Automation

  • Use Python and ClickHouse for analysis, monitoring, and process support;
  • Work closely with product and engineering teams to implement improvements;
  • Where possible, build scripts or LLM-based helpers to automate repetitive tasks — but be ready to handle the parts that still require manual attention.

What You’ll Need

  • A degree in a relevant field (Computer Science, Data Analytics, Engineering, or another technical discipline);
  • Strong analytical thinking and attention to detail — you’ll frequently review data, spot anomalies, and work through repetitive validation tasks;
  • Practical Python skills for data processing and analysis (Pandas);
  • Ability to query databases and work with analytical data stacks;
  • Readiness to handle routine and sometimes monotonous work — dataset checks, manual validations, and weekly quality reviews are a core part of the role;
  • A process-oriented mindset: ability to follow existing workflows, maintain consistency, and keep documentation and reports up to date.

Nice to Have

  • Experience with ClickHouse
  • Strong systems thinking, attention to quality, and a proactive mindset.
  • Experience using semi-automated labeling tools or active learning methods.

Candidates are required to be authorized to work in the U.S. The employer is not offering relocation sponsorship, and remote work options are not available.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
