AI Engineer (Platform Engineering)

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 who bridges the gap between pure AI/ML and high-performance software engineering. This is a hybrid role combining AI/ML Ops platform management, rigorous inference optimization, and AI backend engineering. You will be responsible for taking trained models out of the lab and orchestrating them into resilient, ultra-low-latency production systems.

This is an opportunity to own the deployment lifecycle and infrastructure architecture-building complex agentic workflows and self-hosted clusters that power critical financial operations.

Key Responsibilities

• Inference & Optimization: Deploy, profile, and aggressively optimize models.
• MLOps & Platform: Design and maintain robust pipelines for continuous integration, delivery, and automated testing of ML models. Manage self-hosted GPU clusters and containerized orchestration.
• AI Software & Agent Orchestration: Architect and implement complex AI agent workflows. Build robust APIs, persistent memory layers, and backend services to connect core inference engines with client-facing applications.
• Developer Productivity: Leverage advanced development tools and AI coding assistants to rapidly prototype, debug, and scale complex architectural solutions.
• Security & Compliance: Ensure all self-hosted infrastructure, data pipelines, and open-source integrations strictly comply with regional data sovereignty regulations.
• Cross-Functional Collaboration: Partner closely with foundational ML researchers, frontend product teams, and enterprise clients to ensure POCs and production systems scale seamlessly.

Qualifications

• Bachelor's or master's degree in computer science, Software Engineering, or a related technical field.
• Minimum of 1+ years of engineering experience with a heavy focus on MLOps, ML Infrastructure, or high-performance Backend/Systems Engineering.
• Deep, hands-on expertise with Python, C++, or Go
• Strong experience with Kubernetes, Docker, and infrastructure-as-code within self-hosted or bare-metal environments.
• Experience with cloud-based deployment (preferably Google Cloud Platform) and containerized services (Docker, Kubernetes).
• Solid understanding of system design, API development (FastAPI/gRPC), and building complex software architectures around non-deterministic AI outputs.
• A product-oriented mindset with the ability to troubleshoot complex latency bottlenecks across the entire network and hardware stack.

Nice-to-Have

• Hands-on experience building and orchestrating AI Agents, including identity layers and RAG pipelines.
• Experience processing and extracting data from complex documents or working with specialized open-source models (e.g., OlmOCR).
• Previous experience deploying AI or secure software solutions within the fintech, banking, or BFSI sectors.
• Active contributions to open-source projects.

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.
