Solution Architect, HCLTech www.hcltech.com

Noida / Full-Time

We are HCLTech, one of the fastest-growing large tech companies in the world and home to more than

223,000 people across 60 countries, supercharging progress through industry-leading capabilities centered around Digital, Engineering, Cloud and AI.

The driving force behind that work, our people, are diverse, creative, and passionate, raising the bar for excellence on a regular basis. We, in turn, work hard to bring out the best in them as we strive to help them find their spark and become the best version of themselves that they can be.

If all this sounds like an environment you’ll thrive in, then you’re in the right place. Join us on our journey in advancing the technological world through innovation and creativity.

What Will You Own The end-to-end architecture of the platform: how the integration bus, semantic layer, agent runtime,

workflow engine, and data stores fit together, and how that design scales across multi-tenancy, 10,000

concurrent runs, and enterprise security reviews.

You will make the critical technology decisions early, including the durable execution engine, vector store,

and tenancy model. You will also remain hands-on, writing code for the most complex and critical component of each release.

Responsibilities

- Own the target architecture and the architecture decision records; decide the durable workflow engine, tenancy model, and data-store boundaries in the first two weeks.
- Design and hands-on build the semantic layer's resolution engine (plain-language definition →

systems, tools, rights) with the AI engineers.

- Set the standards the team builds to: API contracts, event schemas, adapter contract, state schema for the supervisor graph, security baseline.
- Run design reviews for every epic; unblock engineers on hard problems; review the code that matters.
- Own non-functional requirements: scalability, isolation,



latency budgets, data retention, and disaster recovery, and prove them with load tests and drills before Go-Live.
- Be the technical voice with pilot customers' architects and security teams.

Must Have

- Designed and shipped a multi-tenant SaaS or platform product used at scale; can explain the trade-offs you made and what you would change.
- Deep, current knowledge of distributed systems: durable workflows or sagas, event streaming with Kafka, idempotency, back-pressure, failure modes.
- Robust data architecture across relational, in-memory, and vector stores; you know what belongs where and why.
- Working experience with LLM-based systems in production: tool calling, agent orchestration frameworks (LangGraph or equivalent), RAG, evaluation. Not slideware, you have debugged a misbehaving agent.

Classification: Internal

- Enterprise integration experience: connecting to CRMs, ERPs, and legacy systems over REST,

SOAP, JDBC, files; authentication and rate-limit realities.

- Security architecture for B2B software: RBAC, tenant isolation, secrets, PII handling; comfortable in a pen-test readout.

Good To Have

- Temporal in production.
- Apache Camel or another integration framework.
- Kubernetes operations at scale.
- A published talk, paper, or open-source contribution.
