Team: Engineering / IT Applications
Type: Full-Time
About the Role
Sapphire Labs is looking for a Senior GenAI / Bedrock Engineer to join a high-impact client initiative through one of our strategic partners. This is a client-facing role focused on building and scaling production-grade Generative AI capabilities on AWS.
The ideal candidate has real-world experience shipping multi-tenant LLM solutions in production using AWS Bedrock — not just experimentation or research projects. We are looking for an engineer with strong platform and infrastructure instincts who can build reliable, scalable, observable GenAI systems.
What You’ll Do
Design and implement production-grade GenAI applications using AWS Bedrock
Build and maintain scalable multi-tenant AI platform architectures with strong tenant isolation and security practices
Develop and deploy containerized AI workloads on AWS ECS
Optimize token usage, inference costs, and workload performance across LLM pipelines
Implement observability, monitoring, and validation frameworks for AI systems
Develop safeguards for hallucination detection, validation workflows, and responsible AI behaviors
Collaborate directly with client engineering leadership in a highly technical, client-facing environment
Support scalable deployment, reliability, and operational excellence practices for GenAI services
Key Experience
Production experience with AWS Bedrock
Multi-tenant SaaS architecture
AI / LLM infrastructure engineering
MLOps, monitoring, and observability
AWS ECS, CI/CD, and cloud-native architecture
Strong client-facing communication skills
Required Skills
5+ years of software engineering experience with recent hands-on GenAI platform work
Hands-on AWS Bedrock experience including:
Model invocation
Bedrock Agents
Guardrails
AWS ECS architecture for containerized workloads and multi-region deployments
Strong experience building and scaling multi-tenant SaaS platforms
Strong understanding of data isolation and tenant configuration patterns
Token optimization experience including:
Consumption modeling
Cost analysis
Workload profiling
MLOps practices including:
Model validation frameworks
Hallucination detection

Azure AI Services exposure for multi-cloud environments
Java backend integration experience
Familiarity with DAMA-DMBOK or DCAM frameworks
Experience working with cybersecurity or regulated industry platforms
Experience with CI/CD pipelines and infrastructure automation
What We’re Looking For
We are specifically looking for engineers who have shipped production-grade, multi-tenant LLM solutions on AWS Bedrock. This is not a research, prompt engineering, or experimentation-focused role — strong platform engineering, cloud architecture, operational ownership, and production experience are essential.
