Job description

Aura Cloud is a class leading cloud platform for financial institutions to launch and run their business at light-speed. Our platform is at the center of our customer's digitization path and business critical.

We provide 24/7 platforms for critical core financial applications that require a very high degree of quality and stability of the platform. We are fast expanding into other markets with continued focus in the Nordics

We seek an experienced Platform Engineer (Principal / Lead) to join the Platform Engineering Team at our Bengaluru office, to architect and build secure, scalable, multi-tenant platform services and the underlying AI infrastructure that powers our core banking and financial solutions / platforms.

About AuraCrew

AuraCrew is an AI-native platform for building, governing and deploying AI agents and agentic workflows ("SmartFlows") for banks and insurers - with model-risk and regulatory governance built into the product.

The Role

The full stack of AuraCrew: NestJS / PostgreSQL services, the React / TypeScript app, and the AWS / VPC deployment, security and observability.

What You'll Own

AuraCrew's AI core on AWS Bedrock / AgentCore: agent authoring and runtime, RAG / knowledge, and the AI Shield / Eval Center / oversight layers.

What You'll Do

• Build and harden multi-tenant services (agents, SmartFlows, governance, versioning) across NestJS + PostgreSQL; own the data model, migrations and performance.
• Own the VPC deployment story: CloudFormation stacks into customers' AWS accounts, IAM / KMS / Secrets Manager, zero-config bank-grade security.
• Run the AI-systems infrastructure the product depends on: agent runtimes (AgentCore), vector / RAG stores, model bindings, the runtime data-plane bridge, OpenTelemetry tracing.
• Raise the engineering bar - observability, CI/CD, release & versioning, production edit policies, incident readiness.
• Ship whole slices across backend and React, AI-amplified.

What You'll Bring

• 8+ years building production software; 3+ years running AI-systems infrastructure in production (agent runtimes, LLM serving, RAG / vector, evaluation pipelines) at real scale.
• Deep TypeScript / Node (NestJS or equivalent) + PostgreSQL; solid React / TypeScript.
• Deep AWS: VPC, IAM, KMS / Secrets Manager, Lambda, S3, CloudFormation / IaC; security-first instincts.
• A track record of productionizing a multi-tenant platform (not just apps): migrations, performance, hardening, on-call.

Bonus

Bedrock / AgentCore; multi-account / VPC SaaS delivered into regulated enterprises; strong Python.

Not The Right Fit If

You've built apps but never owned the platform beneath them, or you prefer to design and delegate rather than ship.

How We Hire

One bar, tested the same way: a deep dive on real work you've shipped - architecture, trade-offs, and what was actually yours - then a paired working session on a live AuraCrew problem in your area. We optimise for depth, judgement and ownership, not breadth of buzzwords.
