About the Role

Cake, a leading Vietnamese digital bank with a rapidly growing user base exceeding 6 million, is on a mission to become the NextGen AI Bank. We leverage cutting-edge AI and data science across all our products and services — and we believe generative AI will redefine what banking can be: smarter, faster, and more human.

We are seeking a Senior AI Engineer to drive the development of our generative AI capabilities, with a focus on large language models (LLMs), foundation models, and generative architectures. You will work across the full lifecycle — from researching and adapting foundation models to deploying scalable, reliable AI services in production for millions of users.

This is an opportunity to combine frontier model research with tangible, large-scale impact — building intelligent, secure generative AI for digital banking.

Key Responsibilities

Research, build, and adapt LLMs, foundation models, and generative architectures for real-world banking applications.
Explore and design model architectures and training approaches, pushing the boundaries of model performance and efficiency.
Build pipelines for data preparation, training, fine-tuning, evaluation, and deployment of generative models at scale.
Optimize models for latency, cost, and reliability in production, and monitor their performance over time.
Ensure responsible AI practices — fairness, safety, and compliance with banking regulations.
Collaborate with product, backend, data, and MLOps teams, and mentor junior engineers.

Qualifications

Bachelor's or Master's degree in Computer Science, AI/ML, NLP, or a related field.
Minimum of 3+ years of experience in AI/Machine Learning, with hands-on focus on LLMs, NLP, or generative models.
Proven experience developing and deploying AI/ML models to production environments.
Strong hands-on experience with Python and modern deep learning frameworks (e.g., PyTorch, Hugging Face).
Solid understanding of deep learning and transformer-based architectures, including training and fine-tuning of large models.
Familiarity with cloud platforms and containerized deployment (preferably Google Cloud Platform).
Influential publications at top-tier AI venues (NeurIPS, ICLR, ICML, ACL, CVPR, etc.) demonstrating strong research taste and technical depth.
Strong problem-solving skills, a product-oriented mindset, and excellent cross-functional collaboration.

Nice-to-Have

Pre-training or large-scale fine-tuning experience on foundation models.
Familiarity with the latest advances in generative AI and a track record of quickly adopting emerging techniques.
Notable open-source contributions to the generative AI ecosystem.
Experience deploying generative AI in fintech or digital banking environments.

Why You'll Love Working at Cake

Build generative AI systems used daily by 6+ million users — your work makes an immediate, tangible impact.
End-to-end ownership: from foundation-model research to production deployment.
Work with a cutting-edge cloud-native stack (GCP, Vertex AI, Kubernetes, Airflow) and large-scale GPU compute.
Collaborative, high-performing tech culture where experimentation and innovation are encouraged.
Competitive compensation and the opportunity to grow within a fast-scaling digital bank.

Our Benefits

Competitive compensation including a 13th-month wage and up to 3 months of performance-based bonus.
MacBooks are supplied to all technical team members.
BE Corp budget (varies by level) for transportation, food, and car bookings in the Be application.
Social insurance contribution amount based on individual level.
Annual health checks and premium medical healthcare (PTI) after probation.
15 days of annual leave for all staff.
Company trips, team-building activities, and happy-hour events on a quarterly or annual basis.
