we're looking for a Platform Architect who can set the standard for how we build, ship, and operate ML and AI systems at scale.
You sit at the intersection of ML infrastructure and SRE.
You'll own the path from model and pipeline to reliable production service, and you'll bring DevOps rigor to systems that are historically under-engineered.
The immediate focus is AI/ML infrastructure on Google Cloud.
This is not a ticket-processing role, and it's not a research role.
You'll tackle hard problems: model serving reliability, inference cost and latency, reproducible pipelines, and agentic workload operations.
You'll have the scope to solve them properly.
Senior professionals here identify problems before they're asked and raise the ceiling on what the platform can do.WHAT YOU'LL WORK ONBuild and operate model and inference serving infrastructure, managing latency, throughput, autoscaling, and reliability for real-time and batch inference across multiple tenants.Own the ML deployment lifecycle: model registry, versioning, promotion workflows, rollout strategies (canary, shadow, A/B), and safe rollback.Operate agentic and LLM workloads in production, managing inference providers and gateways, quota and throttling behavior (TPS/TUPS limits), guardrails, prompt/version management, and graceful degradation under load.Build reproducible, automated ML pipelines: training, evaluation, and deployment pipelines as code, with lineage and reproducibility built in.Extend infrastructure-as-code to ML systems, using Terraform patterns and multi-project design that bring ML infrastructure under the same standards as the rest of the platform.Operate rsements, or GRC—to build, optimize, and scale the backend microservices that drive our financial operations.
This is a unique opportunity for a talented engineer who is passionate about secure, high-performance financial systems and has experience in building solutions that handle complex payment, compliance, and disbursement workflows.
