Role Overview
We are seeking a highly experienced Principal Engineer to lead the design and evolution of the enterprise-scale platform architecture that powers Freshworks' multi-tier SaaS products. This role will define the architecture strategy for a major platform domain, drive modernization initiatives, and establish best practices across service design, reliability, engineering quality, and cost.
The ideal candidate combines deep technical expertise in distributed systems, multi-tenant SaaS architecture, microservices, event-driven design, and large-scale production operations with strong leadership and stakeholder management capabilities - and remains genuinely hands-on, writing production code and leading deep debugging when it matters.
Key Responsibilities
Architecture & Strategy
- Define and own the platform architecture roadmap for your domain, including the target state and a realistic path to it.
- Design scalable, secure, and cost-efficient architectures supporting high-throughput, low-latency, multi-tenant workloads.
- Establish architecture standards, design principles, decision records, and review practices.
- Evaluate emerging technologies and own build-versus-buy decisions with measurable outcomes.
Platform Engineering
- Architect and build cloud-native services and APIs that scale with global growth.
- Design service decomposition, API contracts, messaging and event-driven flows, caching strategies, and database-layer design.
- Treat multi-tenancy as a first-class design concern: isolation models, noisy-neighbour control, per-tenant limits, and cost attribution.
- Lead platform modernization - monolith decomposition, migrations, and deprecations carried through to completion.
Reliability, Performance & Operations
- Drive platform reliability, availability, performance optimization, and observability.
- Take ownership of complex production issues in distributed SaaS environments, leading deep root-cause analysis and implementing permanent preventive safeguards.
- Define SLOs, failure modes, resilience patterns, and capacity planning for the systems you own.
Engineering Excellence & Quality
- Write clean, maintainable, high-performance production code and build proof-of-concepts that settle architectural questions.
- Establish rigorous engineering standards through code reviews, automated testing, and CI/CD integration.
- Identify architectural bottlenecks and technical debt, and drive practical, iterative refactoring without compromising business delivery.
Security, Privacy & Compliance
- Ensure platform designs and team practices align with information security standards and regulatory requirements.
- Design for tenant isolation, access control, auditability, and data residency from the outset.
Technical Leadership
- Provide architectural guidance across multiple engineering teams.
- Lead architecture reviews, design discussions, and technical decision-making.
- Mentor senior and staff engineers, raising the bar through reference implementations and sponsorship rather than authority.
- Influence engineering strategy and long-term technology investments; articulate complex trade-offs to both technical panels and executive stakeholders.
Required Qualifications
- Bachelor's or Master's degree in Computer Science, Engineering, Information Systems, or a related discipline - or equivalent practical experience.
- 14+ years of experience in software engineering, platform engineering, or systems architecture within modern distributed SaaS environments.
- Expert-level backend engineering in Java, Python, Go, or equivalent - currently hands-on.
- Proven experience designing and operating enterprise-scale, multi-tenant SaaS platforms, with real numbers for throughput, latency, availability, and behaviour under failure.
- Strong understanding of distributed systems fundamentals: consistency and idempotency, retries and backpressure, concurrency, caching, and database design and optimization.
- Demonstrated ownership of large-scale migrations or modernization initiatives with measurable outcomes.
- Advanced production debugging skills - Linux internals, profiling, log analysis, and telemetry in distributed cloud environments.
- Experience leading cross-functional architecture initiatives in SaaS or product organizations.
Good to Have
- Data Platform & Analytics
- Batch and real-time data ingestion, transformation, and serving architectures; streaming and CDC (Kafka, Kinesis, Debezium).
- Lakehouse and modern data platform technologies such as Delta Lake, Iceberg, Databricks, Snowflake, and cloud-native data services.
- Reusable data models, semantic layers, and curated data products enabling self-service analytics.
- Data governance practice - metadata management, cataloging, lineage, and data quality frameworks.
- Feature and training data architectures supporting AI/ML initiatives.
Adjacent Experience
- ClickHouse, OpenSearch, or similar analytical and search engines.
- AI-native product capabilities - RAG, agentic workflows, and LLM inte
