About Company
Sigma AI is a global data collection and annotation company focused on AI and ML projects.
Sigma AI provides training data and annotation services to help machine learning models improve across speech, text, and image tasks. The company works with international clients and supports many languages, including Tamil and English, and aims to produce accurate, ethical, and inclusive datasets. Joining Sigma AI means contributing to real AI projects while learning best practices in data quality and annotation workflows.
Job Location
Fully remote — work from home (global, with Tamil language focus).
This role is remote and allows you to work from anywhere with a stable internet connection, though many tasks require Tamil and English fluency. You can log into the platform 24/7 and pick projects based on availability, making it a flexible option for students, freelancers, and homemakers. Some projects (like audio collection) may ask for an Android phone, so check task details before applying.
Job Role
Freelance Data Annotation / Transcription / Validation — Tamil & English.
You will work as a freelance annotator or transcriber performing tasks such as labeling text, validating AI outputs, transcribing audio, recording voice samples, and localizing content for Tamil speakers. Projects vary in scope and can include categorization, correction, conversational interaction, and short content creation. The role suits both freshers and experienced workers who enjoy detail-oriented, remote work.
Job Description
Complete annotation, transcription, validation, and related tasks on Sigma’s platform.
Your daily tasks depend on the project assigned but typically involve reading instructions carefully, tagging or transcribing data with high accuracy, and submitting work before deadlines. You may also take short qualification tests and follow project-specific quality checks. Clear communication, attention to nuance in Tamil and English, and consistent output are important for success in this role.
Education Qualification
No strict degree requirement — language fluency and accuracy matter more.
Sigma AI accepts freelancers with varied educational backgrounds as long as they can read and write in Tamil and English with good accuracy. High school graduates, college students, and degree holders can apply; prior annotation experience is helpful but not mandatory. The selection focuses on test performance and task quality rather than formal qualifications.
Skills Required
Fluency in Tamil and English, basic computer skills, attention to detail.
Essential skills include accurate reading and writing in both languages, the ability to follow written instructions, and basic use of browsers and spreadsheets. Good typing speed for transcription tasks, careful listening for audio work, and the aptitude to learn annotation tools quickly are valuable. Familiarity with Google Sheets or Excel is a plus but not strictly required for every task.
Salary
Expected pay range: ₹25,000 – ₹45,000 per month (project and performance dependent).
Payment depends on the volume and complexity of projects you accept and how efficiently you complete them. Some months will be higher if you take on more work or high-paying tasks; others may be lighter depending on project availability. The provided range is an estimate based on typical freelance earnings for active contributors on data annotation platforms.
Job Type
Freelance / Commercial contract — fully remote engagement.
This is a commercial freelance role where you contract to complete tasks on Sigma AI’s platform. You choose when to work and which projects to accept, giving you freedom over hours and workload. Because it’s freelance, there are no fixed employment benefits, but flexible scheduling and varied projects are major advantages.
Shift and Schedule
Flexible hours — platform available 24/7; work as per your convenience.
You can log in at any time that suits you and pick tasks that match your schedule, which makes this ideal for part-time or supplementary income. Some time-sensitive projects may have stricter windows, so plan around deadlines and test instructions. For audio collection tasks you may need to use an Android phone and follow specific recording windows or guidelines.
Benefits
Remote work flexibility, global exposure, skill growth in AI data practices.
Working with Sigma AI gives exposure to real AI projects, experience with annotation tools, and an understanding of how training data shapes models. Freelancers gain flexibility, the ability to build a portfolio of annotated work, and opportunities to learn about speech recognition, NLP, and localization. The role can open doors to more advanced AI/data roles over time.
