Key Responsibilities

1. AI Architecture and Platform Engineering

Design and deliver the architecture of the bank’s AI infrastructure and platform, covering data, training, fine-tuning, evaluation, model registry, model serving, inference gateway, identity, auditability, observability, and operations. Develop architectures for offline training, batch prediction, real-time inference, high-concurrency serving, and multi-model collaboration. Establish architecture standards, interface specifications, technical baselines, and platform evolution roadmaps.

2. Model Training and Data Processing Infrastructure

Build repeatable, scalable, and auditable model-training infrastructure for supervised learning, deep learning, large language models, and other machine-learning workloads. Own training orchestration, dataset management, data preparation, feature processing, experiment tracking, model evaluation, resource scheduling, training logs, metric collection, and model-artifact management. Optimize data, compute, network, storage, and communication efficiency for training workloads.

3. Model Fine-Tuning and Large-Model Engineering

Design and implement infrastructure for fine-tuning large language models and domain-specific models, supporting instruction tuning, supervised fine-tuning, parameter-efficient fine-tuning, and relevant preference-optimization workflows. Understand and apply techniques such as LoRA, QLoRA, adapters, quantization, distillation, mixed precision, gradient accumulation, checkpoint management, and distributed training. Integrate these capabilities into standardized training, evaluation, release, and rollback processes. Work with data, model-risk, business, and security teams to ensure that training data and model artifacts meet internal governance requirements.

4. Kubernetes and Cloud-Native Platform Engineering

Build and operate AI workloads on Kubernetes (K8s), including containerization, Pod scheduling, GPU allocation, node-pool management, autoscaling, job queues, network policies, service discovery, storage orchestration, namespace isolation, quota management, and multi-tenant governance. Work with Helm, Operators, Ingress, service mesh, CI/CD, GitOps, Terraform, or equivalent technologies. Troubleshoot reliability, performance, scheduling, and resource-isolation issues for training and inference workloads running on Kubernetes.

5. Model Serving and Inference Optimization

Build a unified model-serving platform and model gateway for conventional machine-learning models, deep-learning models, and large language models. Own model containerization, version management, canary releases, A/B testing, rate limiting, circuit breaking, caching, batch inference, asynchronous invocation, and multi-model routing. Continuously optimize inference latency, throughput, GPU/CPU utilization, memory consumption, concurrency, and cost per request. Experience with model quantization, continuous batching, KV cache, inference caching, or other acceleration techniques is preferred.

6. MLOps/LLMOps and Delivery Automation

Build automated workflows covering data preparation, training, fine-tuning, evaluation, model registration, approval, release, and production monitoring. Maintain traceability among model versions, dataset versions, code versions, configuration parameters, and experiment results to ensure reproducibility, rollback, and auditability. Provide standardized SDKs, APIs, templates, pipelines, and self-service tools for data-science, machine-learning, and application teams.

7. Security Hardening, Reliability, and Resilience Engineering

Establish security baselines and production-reliability mechanisms for the AI platform, including authentication, fine-grained authorization, secrets and key management, network segmentation, data masking, sensitive-data protection, image and dependency scanning, software supply-chain security, runtime protection, vulnerability remediation, audit trails, and anomaly detection. Define service-level objectives, capacity-management practices, incident-response procedures, backup and recovery plans, business-continuity controls, disaster-recovery failover, and regular resilience testing. Improve recoverability under traffic surges, dependency failures, hardware failures, model anomalies, and security incidents.

8. Observability and Production Operations

Build unified observability across infrastructure, training jobs, model services, data pipelines, and business indicators. Use logs, metrics, distributed tracing, model-quality indicators, data-drift detection, performance metrics, and cost metrics to diagnose platform and model issues. Participate in production on-call rotations, major-incident reviews, capacity planning, performance testing, and platform upgrades, driving root-cause remediation rather than temporary fixes.

9. Technical Leadership and Cross-Functional Delivery

Own technical design reviews, proof-of-concept validation, solution decomposition, production acceptance, and documentation for key initiatives. Mentor software, machine-learning, platform, SRE, data, security, and risk engineers. Participate in technical hiring, interviews, code reviews, and architecture reviews, helping the organization build standardized, reusable, and continuously evolving AI engineering capabilities.
