At OnTheGoSystems, we're building AI systems that help people translate content across many languages. Our LLM team works with AI-generated translations, user edits, customer feedback, and quality data to continuously improve translation quality.

We're looking for a Data Analyst who enjoys solving open-ended problems, finding patterns in complex datasets, and turning data into practical recommendations. This is not a reporting role. You'll decide what to measure, investigate why things happen, and help the team make better decisions based on evidence.

What You'll Do

You'll own analytical problems from start to finish.

For example, you may discover that users edit translations much more often for one language pair than another. Instead of simply reporting it, you'll investigate why. You'll form hypotheses, gather the data, test possible explanations, and recommend the next steps.

Your work will include:

Defining meaningful metrics for translation quality, AI performance, and user behavior
Monitoring trends and identifying unusual patterns or quality issues




Turning observations into structured investigations and testing multiple hypotheses
Extracting and combining data from SQL databases, NoSQL databases, logs, APIs, and CSV exports
Comparing results across language pairs, AI models, providers, customers, content types, traffic levels, and other dimensions
Separating real signals from coincidence by validating findings with data
Reviewing translation samples to confirm whether patterns represent genuine quality issues
Investigating root causes and recommending practical improvements
Evaluating multilingual AI output for meaning, terminology, tone, formality, grammar, pronouns, and consistency
Using AI tools, dictionaries, and other resources to investigate languages you don't speak, while recognizing when expert linguistic input is needed
Reviewing AI-generated analyses, identifying incorrect conclusions, and helping improve our automated evaluation systems
