LeadSquared is hiring a Principal Architect in Bangalore for its Core Platform. This senior IC role reports to the CTO and involves defining target-state architecture, mentoring senior engineers, and driving technical strategy for a global SaaS platform.

About the Company

LeadSquared is a rapidly growing SaaS platform that powers high-velocity sales and customer engagement execution across global industries, including BFSI, Education, Healthcare, and Marketplaces. The company builds large-scale, mission-critical systems focused on performance, reliability, and innovation. With an expanding product portfolio and new AI-native capabilities, LeadSquared is looking for a Principal Architect to shape the technical foundation that will carry the business into its next phase of growth.

Role Overview

We are seeking a Principal Architect for our Core Platform who combines deep technical architecture skill with a strong grasp of LeadSquared’s technology, product, and business landscape. This is a senior individual-contributor role reporting directly to the CTO, built around technical ownership and influence. You will own the target-state architecture of the core platform: defining where it needs to go to support the future direction of our products and business, and charting a credible, phased path to get there. Equally important, you will be a magnet and mentor for our most talented senior engineers, raising the technical bar across the organisation and giving high-potential IC talent a compelling reason to grow and stay at LeadSquared.

Key Responsibilities

Platform & Technical Strategy

• Build and maintain a deep working understanding of LeadSquared’s technology stack, product portfolio, and business/customer landscape across BFSI, Education, Healthcare, and Marketplaces.
• Define and drive the target-state architecture for the core platform covering scalability, multi-tenancy, extensibility, performance, security, Infra Cost, and data architecture.
• Translate the future direction of product and business—including emerging AI-native and agentic capabilities—into a coherent, sequenced architecture roadmap.
• Establish architectural principles, standards, and guardrails across services, APIs, data, and integration layers, and ensure they are consistently applied.
• Evaluate new technologies, platforms, and patterns (cloud-native, data, AI/agentic) that keep the platform future-ready and competitively differentiated.
• Make and own architectural trade-off calls that balance paying down technical debt against the pace of new capability delivery.

Cross-Functional & Business Alignment

• Partner closely with the CTO, Engineering and Product leadership, and business stakeholders to keep platform architecture aligned with product strategy and market direction.
• Represent core platform architecture in leadership forums, bringing a technical lens to business and product decisions.
• Assess build-vs-buy, platform consolidation, and modernisation choices through a business-outcomes lens, not just a technical one.
• Engage with customers and internal stakeholders as needed to validate that architectural direction holds up against real-world use cases.

Talent Development & Mentorship

• Inspire and mentor senior engineers, tech leads, and architects across the organisation, raising the overall quality of technical thinking and decision-making.
• Build structured mechanisms for coaching and knowledge-sharing—design reviews, architecture forums/guilds, RFC and ADR processes—that scale good architectural practice beyond any one team.
• Act as a magnet for senior IC talent: create a visible, credible technical growth path that improves engagement and retention of high-potential engineers.
• Champion engineering best practices—design reviews, architecture decision records, documentation, and code quality—as habits, not one-off exercises.

Hands-On Technical Leadership

• Stay hands-on: prototype, review designs and code, and work directly alongside teams on the platform’s hardest problems.
• Lead resolution of the most complex, cross-cutting architectural challenges such as scale, reliability, data consistency, and security.
• Set up lightweight governance (architecture review forums, a technology radar) that keeps the platform coherent as teams and services multiply.

Tech Stack

• Programming Languages: Java / .NET (C#)
• Cloud Platforms: AWS, Azure, or GCP (preferably AWS)
• Architecture: Microservices, Distributed Systems, Multi-tenancy
• Databases: SQL (e.g., PostgreSQL, MySQL) and NoSQL (e.g., MongoDB, Cassandra, DynamoDB)
• AI / ML: RAG patterns, LLM orchestration, vector search (e.g., Pinecone, Weaviate, LangChain)
• Infrastructure: Containerization (Docker, Kubernetes), CI/CD pipelines, Infrastructure as Code
• Additional: API design, Event-driven architecture, Security best practices, Cost optimization

This role offers a unique opportunity to influence the technical direction of a global SaaS platform while mentoring the next generation of engineering leaders. You will work at the intersection of core platform, product, and emerging AI capabilities.

14–20 years of overall software engineering experience with significant and recent track record in architecture and technical leadership roles on large-scale, multi-tenant SaaS platforms. Proven experience owning target-state or reference architecture for a platform of meaningful scale and complexity. Strong hands-on background across modern technology stacks (Java/.NET, cloud-native services, microservices, distributed systems). Solid understanding of database technologies (SQL & NoSQL) and system design trade-offs at scale. Working knowledge of cloud platforms (AWS/Azure/GCP) and cloud-native architecture practices. Familiarity with AI/ML and agentic architecture patterns (RAG, LLM orchestration, vector search) is a strong plus. Demonstrated ability to mentor and elevate senior engineers without formal reporting authority. Excellent communication and stakeholder management skills.

Competitive compensation; opportunity to shape target-state architecture of global SaaS platform; high-ownership role reporting to CTO; chance to mentor senior engineers and leave lasting technical legacy.
