Principal AI Engineer

Location: India (Bengaluru) - 3(WFO)

Employment Type: Full Time (Overlapping EST)

Experience Level: Staff/Principal (8–14 years) 

Working Hours: Comfortable with a daily overlap into US Eastern morning hours (8AM - 12 PM EST)

• 8–14 years of software engineering experience, with strong hands-on large-scale Python

• Working depth in at least one systems or backend language — Go, Rust, Java, or C/C++ — and the judgment to know when to reach for it

• Strong data structures and algorithms. 

• Strong understanding of APIs, microservices, and system design

• Hands-on experience building and operating data pipelines and production-grade distributed systems.

Agentic AI and LLMs

• 2+ years of hands-on LLM engineering, with at least couple agentic system you designed and took to production

• Production experience with agent frameworks — LangGraph, Google ADK, CrewAI, Claude Agent SDK, or equivalent — and the fluency to move between them as the ecosystem evolves

• Experience building MCP (Model Context Protocol) servers and tool-calling interfaces

• RAG from first principles: chunking strategy, embeddings, vector and hybrid retrieval, reranking, and response validation

• Strong experience with vector databases (Milvus, Pinecone, Weaviate, FAISS, etc. or cloud equivalents)

• Design of guardrails and reliability patterns — validators, policy checks, self-correction loops, deterministic fallbacks, circuit breakers, and rollback paths

• 
  

Optimization

• Deep familiarity with token optimization and context-window management — context shaping, pruning, and compaction

• Latency and cost optimization through caching, model routing, batching, streaming, and parallel tool calls

• Performance testing and tuning systems against defined SLOs

Evaluation

• Experience building evaluation frameworks for LLM systems — offline eval sets, continuous online evaluation, and regression detection

• Instrumentation and traceability suitable for regulated enterprise environments using tools like LangSmith, Langfuse, etc.

Cloud

• Hands-on AWS: containerized services (ECS/EKS), serverless (Lambda), data services (S3, DynamoDB, Redshift) and orchestration (Step Functions)equivalents also valued

• Familiarity with CI/CD pipelines and DevOps practices

• Infrastructure as code with Terraform or CloudFormation, and mature CI/CD practice

Working traits

• Strong analytical problem-solving with a bias to ownership and urgency

• Clear cross-team communication, working directly with client stakeholders to translate business problems into technical roadmaps

• Able to work productively in ambiguity from system-level documentation and ramp quickly in unfamiliar codebases

• Experience with managed AI platforms — Amazon Bedrock, Vertex AI, Azure AI — paired with fluency in the underlying fundamentals

• Azure or GCP 

• Design and build agentic systems: Lead the architecture and implementation of tool-calling agents that combine retrieval, structured reasoning, and secure action execution with least-privilege access.

• Productionize LLM applications: Build retrieval pipelines, prompt synthesis, response validation, and self-correction loops, backed by rigorous evaluation.

• Own the full stack: Deliver the data pipelines, backend services, distributed compute, and orchestration layer that agentic systems depend on — not only the model invocation.

• Engineer for reliability and governance: Build validator models, adversarial test suites, and policy checks; enforce deterministic fallbacks and rollback strategies; instrument continuous evaluation.

• Optimize for cost and latency: Drive measurable improvements in token efficiency, response time, and unit economics against defined SLOs.

• Codebase ownership: Build, maintain, and review high-quality Python and SQL, with an emphasis on reusable components, scalability, and performance.

• Cloud integration: Deploy AI applications on AWS, Azure, or GCP with optimized resource usage and robust CI/CD.

• Cross-functional collaboration: Partner with product owners, data scientists, and business SMEs to define requirements and deliver impactful AI products.

• Mentoring and technical leadership: Set engineering standards and share knowledge across the team, raising the bar on AI and software engineering practice.
