Full Job Description

📋 Description

  • Are you a meticulous individual with a passion for language and a keen eye for detail? Volga Partners is seeking a dedicated Language Data Quality Reviewer (Entry Level - L1) for Brazilian Portuguese to join our dynamic remote team. This foundational role is crucial in ensuring the accuracy, consistency, and quality of the language data that powers cutting-edge AI and machine learning technologies. As an L1 reviewer, you will be instrumental in identifying and correcting errors, validating linguistic nuances, and contributing to the overall integrity of our datasets.
  • In this role, you will dive deep into various types of linguistic data, including text, audio, and potentially other formats, performing thorough quality assurance checks. Your primary responsibility will be to evaluate data against established guidelines and project-specific instructions, ensuring it meets our high standards for accuracy and relevance. This involves identifying grammatical errors, spelling mistakes, punctuation issues, and semantic inaccuracies. You will also assess the appropriateness of language used, ensuring it aligns with the intended context and target audience.
  • A significant part of your work will involve comparing different versions of data, flagging discrepancies, and providing clear, concise feedback for corrections. You will be expected to meticulously document your findings, using our internal tools and platforms to record issues and their resolutions. This documentation is vital for our data scientists and engineers to understand the nature of the errors and implement improvements in our systems.
  • You will play a key role in the continuous improvement of our data quality processes. By consistently identifying patterns in errors and providing insightful feedback, you will help refine our annotation guidelines and improve the training data for AI models. Your contributions will directly impact the performance and reliability of AI applications, making your role indispensable.
  • This position offers a unique opportunity to gain hands-on experience in the rapidly growing field of AI and data annotation. You will work with a diverse range of linguistic data, expanding your understanding of language and its application in technology. The remote nature of the role provides flexibility and the ability to work from anywhere, fostering a healthy work-life balance.
  • As an L1 reviewer, you will collaborate closely with a supportive team of fellow reviewers and project managers. While working independently on your assigned tasks, you will also participate in team discussions, share insights, and contribute to a collaborative learning environment. Regular feedback and training will be provided to ensure you are equipped with the knowledge and skills needed to excel.
  • The scope of this L1 engagement focuses on the complexity and breadth of tasks involved in foundational data review, not on the candidate's overall career progression. It's an excellent starting point for individuals looking to build a career in data quality, linguistics, or the AI industry. You will develop a strong understanding of data annotation best practices, quality control methodologies, and the specific challenges associated with processing and validating language data.
  • Your day-to-day activities will involve carefully reviewing and annotating text or audio data, ensuring it adheres to specific project requirements. This might include tasks such as transcribing audio, categorizing text, identifying entities, or validating the sentiment of a piece of content. You will be trained on specific annotation tools and platforms, becoming proficient in their use.
  • Attention to detail is paramount. You will be expected to follow complex instructions precisely and apply them consistently across all tasks. Your ability to discern subtle differences in meaning, tone, and context will be highly valued. This role requires a commitment to accuracy and a proactive approach to identifying and resolving any data quality issues that arise.
  • Ultimately, your work as a Language Data Quality Reviewer will contribute to building more intelligent, accurate, and user-friendly AI systems for the Brazilian Portuguese market. You will be a guardian of data integrity, ensuring that the information used to train these systems is of the highest caliber. This is a chance to make a tangible impact in a field that is shaping the future.

🎯 Requirements

  • Native or near-native fluency in Brazilian Portuguese, with an excellent understanding of grammar, spelling, and cultural nuances.
  • Strong attention to detail and a meticulous approach to reviewing and validating data.
  • Ability to understand and follow complex guidelines and instructions accurately.
  • Basic computer proficiency and familiarity with online tools and platforms.
  • Excellent written and verbal communication skills in English (for communication with the global team and understanding guidelines).

🏖️ Benefits

  • Fully remote work opportunity, offering flexibility and work-life balance.
  • Competitive hourly rate.
  • Opportunity to gain valuable experience in the rapidly growing field of AI and data annotation.
  • Access to ongoing training and development resources.
  • Be part of a supportive and collaborative international team.
