Senior Software Engineer - AI Engineering

Bengaluru

Role Summary

Embeds with client teams, understands manual business workflows, and builds AI-agent-powered automation to replace them. Helps build a new agent harness platform from the ground up — to be built on Claude (Claude Code /

Cowork), AWS Step Functions (ASL) and Amazon Bedrock AgentCore, with an AG-UI front end — and then delivers production workflows on it. Owns the solution end-to-end — discovery, build, deploy, evaluate, iterate — working

directly with enterprise customers with minimal direction.

TECHNICAL REQUIREMENTS

Harness Engineering — Core

• Harness engineering — Excellent understanding of designing agent harnesses: the control loop, tool and skill surface,

context and state management, and human-in-the-loop checkpoints around an LLM

• AWS Step Functions with ASL — Author Amazon States Language state machines to orchestrate agent steps,

branching, retries, parallelism and human-approval gates (e.g. task-token waits); invoke AgentCore runtimes and Lambda

from workflows

• Deterministic vs LLM control — Design workflows where policy gates and rules decide routing and the LLM only

proposes, with explicit exception, timeout and loop-guard paths

• Amazon Bedrock AgentCore — Host, operate and scale agent workloads on AgentCore Runtime; understand lifecycle,

scaling and invocation patterns, and expose tools via AgentCore Gateway

• AgentCore Observability — Hands-on tracing, metrics and logging of agent runs (AgentCore, CloudWatch, Datadog)

with a per-step audit trail to debug and monitor production workflows

• AgentCore Evaluation — Hands-on design and running of evaluations (AgentCore Evaluations, golden-dataset

regression tests) to measure agent quality before and after each release

• Guardrails — Hands-on configuration of Amazon Bedrock Guardrails and policy controls for safety, prompt-injection

defence, PII and hallucination mitigation, with human-in-the-loop review where required

Agentic AI with Claude

• Claude Code / Cowork — Experience designing, deploying and scaling AI-powered production workflows using Claude

Code and/or Cowork

• LLM API fundamentals — Tool use, function calling, streaming and context management

• Skill building — Design and publish reusable skills consumable by agent workflows

• MCP (Model Context Protocol) — Build, host and consume MCP servers (e.g. FastMCP on AgentCore); expose and

integrate tools for agent use, with agents reaching data only through MCP/API, never directly

• Multi-agent coordination — Task delegation and result aggregation across agents (A2A)

• RAG pipelines — Vector databases, chunking, embeddings and retrieval

• Prompt engineering — System prompts, evaluation and iteration

Front End

• AG-UI — Build agent-facing user interfaces on the AG-UI protocol, connecting the front end to running agents for

streaming responses, tool-call visibility, shared state and human approval steps

Backend

• Python 3.10+ — async/await, type hints

• FastAPI or equivalent Python web framework

• Basic SQL — query, filter, join; awareness of vector DBs (pgvector, Pinecone, OpenSearch)

• NoSQL — Working knowledge of document/key-value stores (e.g. Amazon DynamoDB): data modelling, access

patterns, and using them for agent run state and audit trails

• REST API design, JWT / OAuth2

Workflow Automation

• Decompose manual business processes into agent workflows

• Document processing — PDF, Excel, unstructured data extraction and classification

AI Engineer

October 2026 JLL Confidential

• OCR — Extract text, tables and layout from scanned and image-based documents (e.g. AWS Textract), and feed the

output into agent workflows

• Enterprise system integration — SharePoint, email, and external systems via APIs and MCP

Infrastructure

• AWS services — Lambda, ECS, RDS, S3, IAM — support agent deployment and data storage needs

• Terraform / Infrastructure as Code — Provision and promote AgentCore, Step Functions, Lambda and supporting AWS

resources across environments

• Docker and containerisation

• GitHub Actions CI/CD

ADDITIONAL SKILLS

• Kubernetes

• TypeScript

• Fine-tuning and model evaluation

• CRE domain knowledge

EXPERIENCE

• Proven experience in software engineering, with hands-on AI engineering shipped to production (years of experience are

not the criterion; depth of AI delivery is)

• At least one production project involving LLM agents, skill building, or RAG pipelines — ideally on AWS Bedrock

AgentCore and/or Step Functions

• Direct experience working with enterprise customers to design, deploy and scale AI-powered production workflows using

Claude Code / Cowork

• Track record of owning and delivering solutions end-to-end with minimal guidance

• Experience working directly with non-technical stakeholders — gathering requirements, presenting solutions

• Consulting or client-facing background is an advantage
