Why join this opportunity?

Our client is an early-stage, well-funded AI startup building a next-generation consumer AI platform designed to help people automate everyday tasks, workflows, and errands through intelligent, real-world task execution.

This is a rare opportunity to join as a founding engineer and help shape both the product and the machine learning foundation from the very beginning. You’ll work alongside an experienced leadership team in a fast-paced, high-trust environment where ownership, curiosity, and execution are highly valued.

What you’ll do

Build and improve production machine learning systems across data pipelines, model training, evaluation, inference, and deployment.
Fine-tune and adapt machine learning models as part of scalable production systems.
Develop evaluation frameworks and testing processes to better understand model performance and behavior.
Build and maintain data pipelines supporting both synthetic and real-world training data.
Debug model behavior, production issues, and system performance using real-world signals.
Continuously improve machine learning systems through iterative development and production feedback.
Collaborate closely with senior machine learning engineers, researchers, and product teams to deliver reliable AI-powered features.
Grow your technical expertise by working on production AI systems that operate under real-world constraints such as latency, reliability, scalability, and cost.

What we’re looking for

Strong foundation in machine learning and modern neural network architectures.
Hands-on experience training, fine-tuning, or deploying machine learning models.
Experience with Python and modern machine learning frameworks such as PyTorch and/or JAX.
Strong software engineering fundamentals and the ability to write reliable, maintainable code.
Curiosity, strong problem-solving skills, and a willingness to learn from real production systems.
Ability to work independently while collaborating effectively with cross-functional teams.
A builder’s mindset with a passion for continuous learning and delivering high-quality AI solutions.
