[Vietnamese-Taiwan]

About the role

This opportunity positions you as a key contributor to the global data ecosystem by independently supplying the speech data that powers next-generation voice AI systems. You will own the end-to-end execution of data collection tasks, ensuring that each recording session meets strict quality and guideline standards without direct supervision. The role requires you to interpret and accurately follow scripted instructions while maintaining a high level of personal discipline and time management. You are responsible for transforming raw linguistic requirements into a clean, usable dataset using only a smartphone and the dedicated Appen Mobile application. This project-based engagement emphasizes reliability, as your contribution directly impacts the performance of voice models used across diverse applications. Because the work is conducted remotely, you must proactively manage your schedule and environment to deliver consistent results. Success in this role depends on your ability to work independently, adhere to precise protocols, and treat every recording session as a professional production activity.

Practical notes

Typical interview steps

Data interviews commonly include a SQL or coding exercise, a statistics question, and a case study. Candidates may be asked to design a metric, interpret an experiment, or build a small model. Some companies give a take-home analysis. Expect questions about past projects and the business impact of your work. Interviewers often evaluate how you communicate uncertainty and business impact, not only the math. Bringing a clean write-up of a past analysis to the interview is well received.

Good to know

Questions to ask

Worth asking in any interview: how the team measures success, who the role works with daily, what the onboarding looks like, and what the company is trying to achieve this year. Asking what past hires did well is a strong final question. Keep the list short and pick the questions that matter most to you.

Career growth

Data careers grow toward senior analyst, staff data scientist, or data engineering lead. Many professionals specialize in machine learning, analytics, or infrastructure. Cross-functional work with product and engineering teams becomes more important at senior levels. The field changes quickly, so continuous learning is part of the job. Professionals who can translate numbers into decisions tend to advance fastest.
