AI Summary

Puritype, a Delaware-headquartered AI startup, is hiring a full-time, remote engineer based in Ho Chi Minh City, Vietnam or open to working remotely. The company is focused on building AI-assisted decision-making systems to support individual opportunities and influence ethical policymaking. In this role, you'll be central to developing the Minimum Viable Product (MVP) of a recommendation engine powered by machine learning and causal inference techniques. The position involves collaboration with researchers to design an end-to-end AI system that utilizes raw sensor input for insight-driven recommendations. You'll optimize and implement algorithms involving statistical modeling, pattern recognition, and counterfactual evaluation to provide decision support. As part of a multidisciplinary team, this role offers a rare opportunity to help shape the early-stage product of a mission-driven startup.

Qualified candidates should bring strong experience in machine learning, deep learning, neural networks, and natural language processing (NLP). Core technical skills include expertise in pattern recognition, software development, data analysis, and building AI-powered recommendation systems. A Master’s or Ph.D. in Computer Science, Engineering, or a related field is required, along with excellent problem-solving and collaboration skills. Prior experience or research exposure to causal inference and statistical modeling is highly desirable.

This is an exciting opportunity to work closely with top researchers and engineers in a collaborative environment, influencing the core product development at a formative stage. If you're passionate about using AI to make meaningful decisions and improve lives, this role offers significant intellectual and mission-driven rewards.

Role Description

This is a full-time remote role for a Senior AI Engineer - AI assisted Decision-making Agent at Puritype. The role involves working on Machine learning, deep learning, neural networks, and natural language processing (NLP) to build innovative AI solutions. The Senior AI Engineer will be responsible for developing and optimizing recommendation and decision-making algorithms and systems.

This job is going to build MVP (minimum viable product). The role will be responsible for developing causal inferences methods to estimate the effect of treatment and implementing machine learning algorithms, pattern recognition. They will also work on data analysis, statistical modeling, and algorithm optimization. The AI Engineer will collaborate with a team of engineers and data scientists to improve agent systems.

As an AI Engineer, you will work with researchers in causal inference to build a recommendation system, where an end-to-end AI system processes raw sensor input to make direct right decisions, we are building an end-to-end AI-based decision-making agent. These algorithms aim to discover the most compelling content on the platform — including posts, promoted content, creators, and videos — based directly on users' activity on the platform. As a key driver of this effort, you will test state-of-the-art methodologies to significantly enhance by Causal inference (Counterfactual evaluation).
