Role Summary:

We are seeking a highly motivated Cloud Backend Engineer for AI Applications to join our team and help us accelerate software innovations for next-generation software-defined vehicles. In this role, you will be responsible for designing and implementing large-scale data processing pipelines and building the cloud infrastructure to support our AI applications. You'll use your deep expertise in cloud architecture and backend development to make critical decisions that span data processing, API design, and cloud service deployment. This is a key leadership position for a hands-on engineer who will define our data governance, infrastructure as code, and production observability best practices.

Role and Responsibilities:

• Design and build the foundational, end-to-end cloud and backend platform for our Generative AI systems. You'll make critical decisions that span data processing, API design, and service deployment.
• Build and scale the data pipelines that are the lifeblood of our applications. This includes processing massive datasets and creating the real-time data flows for our AI systems. You will design and implement large-scale data processing pipelines that handle a diverse set of data collected from millions of vehicles.
• Deploy, scale, and optimize our cloud infrastructure. You will manage hardware resources, minimize inference latency, and build robust monitoring to ensure our AI system is always fast, accurate, and cost-effective. This includes developing and deploying containerized applications using Docker and Kubernetes.
• Create a single, cohesive set of best practices for the entire application lifecycle. Your work will define how we handle data governance, infrastructure as code, and production observability in one seamless system.
• Design secure and scalable networking layers within cloud environments, including VPC design, private/public subnet configurations, NAT/Internet gateways, and load balancers.
• Implement and manage core infrastructure services such as DNS, routing, and service discovery to ensure reliable, low-latency access to cloud services.
• Automate infrastructure deployment using Infrastructure as Code (Terraform, Pulumi, etc.), ensuring repeatability across cloud environments.
• Deliver production-ready CI/CD pipelines for automated provisioning and deployment of containerized workloads.

Requirements:

• A seasoned engineer with 5 years of experience building and scaling data-intensive, cloud-based services and applications.
• Deep expertise in deploying and managing cloud-native workloads on various cloud environments.
• Proven track record of designing highly available and fault-tolerant architectures across multiple regions/zones.
• A "systems thinker" with a demonstrated ability to architect end-to-end solutions, possessing a strong foundation in both Data Engineering and Cloud/Backend Software Development.
• Deep proficiency in Python and/or Go with an emphasis on Infrastructure as Code. 
• Strong programming fundamentals, particularly in data structures & algorithms, and concurrency.
• Hands-on experience with containerization/orchestration (Docker, Kubernetes).
• Experience building and optimizing highly available, scalable, distributed backend services leveraging open source technologies and tools such as Kafka, RabbitMQ, and ElasticSearch.
• Experience with developing data pipelines and database-supported cloud services and applications.
• Ability to deeply analyze, break down, and solve complex problems.
• Good verbal and written communication skills, with the ability to explain complex ideas and solutions clearly, and to collaborate with cross-functional teams effectively.
• MS or PhD in Computer Science, Math, Physics, or related fields.
