Lead AI Engineer

Job Description - Lead AI Engineer
About the Role
As a Lead AI Engineer, you will be responsible for building and scaling the production systems that bring our AI products to life.
You will lead the design and implementation of AI-powered services that enable investors worldwide to assess the Environmental, Social, and Governance (ESG) performance of companies. Your focus will be on production-grade AI engineering: model and LLM inference services, orchestration, retrieval pipelines, scalable APIs, and robust data workflows.
Responsibilities

• Lead the development and scaling of inference endpoints and APIs for classic ML models and LLMs.
• Own end-to-end delivery of AI services from prototype to production: design, build, deploy, and operate.
• Develop and maintain CI/CD pipelines; automate deployments on AWS (e.g., Bedrock, Lambda, EKS, S3, etc.).
• Design and maintain data pipelines, queues, and event-driven workflows to support AI products.
• Integrate vector databases, retrieval pipelines, and RAG patterns into production-grade systems.
• Build and maintain orchestration layers and microservices in Python; contribute to platform services.
• Establish and maintain monitoring, observability, alerting, and cost-aware operations for AI services.
• Implement strong engineering practices: testing strategies, documentation, runbooks, and reliability standards.
• Collaborate with AI researchers and product engineering teams to productize prototypes and deliver measurable outcomes.
• Mentor and guide engineers; drive code quality, design reviews, and operational excellence.

Qualifications

• Strong programming skills in Python (APIs, services, pipelines).
• 7+ years of experience in AI engineering, MLOps, backend engineering, or related roles, with significant production ownership.
• Hands-on experience deploying and operating LLMs in production, with awareness of evaluation, limitations, and cost implications.
• Solid knowledge of AWS services (Bedrock, Lambda, EKS, S3, etc.).
• Experience with CI/CD, containerization (Docker/Kubernetes), and infrastructure automation.
• Understanding of microservices architectures, queues/events, and scalable system design.
• Working knowledge of ML concepts (precision/recall, latency/throughput trade-offs, inference performance).
• Experience with SQL databases (e.g., PostgreSQL).
• Strong communication skills, a product-first mindset, and the ability to translate ambiguity into execution.

Nice to Have

• Experience with JavaScript/TypeScript.
• Experience with Harness.
• Familiarity with monitoring/observability tools (CloudWatch, Prometheus, Grafana).
• Infrastructure-as-code experience (Terraform, CloudFormation).
• Experience with web crawlers or large-scale data ingestion.
