The Opportunity

Architecting the Future of Engagement as a Principal Architect at MoEngage, you will not just design systems; you will define the technical trajectory of the company for the next decade. We are looking for a visionary technologist to lead our "Journey Beyond 2025"—a strategic pivot towards an AI-first, hyper-scale customer engagement platform.

You will hold the blueprint for our reliability, cost-efficiency, and next-generation capabilities. You will be responsible for integrating massive-scale AI initiatives into our core distributed systems, ensuring we remain not just a market leader, but a technology pioneer.

Key Responsibilities:

1. Vision & Strategy (Beyond 2026)

• Architect the AI Transformation: Spearhead the architectural design for MoEngage’s AI-native capabilities. This includes building scalable inference pipelines, training infrastructure, vector database management, and LLM orchestration layers.
• Future-Proofing Infrastructure: Define the "North Star" architecture that supports 100x growth in data volume and complexity. Identify strategic inefficiencies and drive the adoption of paradigm-shifting technologies (e.g. Zero Copy, Real-time Stream Processing).
• Strategic FinOps & Unit Economics: Take ultimate accountability for the cost-efficiency of our cloud footprint. Design systems where cost scales sub-linearly with growth, specifically managing the high-cost implications of GPU compute and AI workloads.

2. Technical Leadership & Execution

• Deep-Dive Problem Solving: Demonstrate the ability to go vertically deep into the network/database level to solve "hard" problems regarding latency, throughput, and consistency in distributed systems.
• Cross-Functional Orchestration: Translate vague business goals into concrete technical roadmaps. Subdivide multi-year strategic initiatives into actionable monthly/quarterly execution plans across multiple engineering verticals.

3. Mentorship & Culture

• Cultivate Engineering Excellence: Raise the bar on sustainable engineering by institutionalizing best practices in observability, chaos engineering, and automated resiliency.
• Executive Advisory: Act as a trusted technical advisor to the business, helping them crack complex integrations, understand customer challenges and help architect solutions.
• Mentor the Mentors: Coach Tech Leads, Staff and Architects, helping them navigate complex technical trade-offs and developing the next generation of architectural leaders at MoEngage.

What You'll Need:

Experience & Education

• 15+ yearsof software engineering experience, with at least2+ yearsin a Principal/Chief Architect role or equivalent.
• BS, MS, or PhD in Computer Science or related field.

Technical Mastery

• Hyper-Scale Distributed Systems: Proven track record of designing systems that handle millions of transactions per second (TPS) and petabyte-scale data ingestion.
• Cloud Native Expert: Deep mastery of AWS/GCP/Azure ecosystems, including container orchestration (K8s), service mesh, and multi-region active-active architectures.
• Database Architectures: Expert-level knowledge of various data stores (NoSQL, NewSQL, Columnar, Time-series) and the ability to choose the right tool for high-throughput/low-latency scenarios.

Leadership & Soft Skills

• Visionary Communication: Ability to write Vision docs
• Product Thinking: You don't just build tech; you understand the "Why." You can articulate how architectural decisions impact the customer experience, reliability and the P&L.
• Resilience & Maturity: A history of navigating high-pressure situations, resolving technical disagreements with grace, and fostering a collaborative, psychological-safe environment.

Bonus Points

• Industry Recognition: You are a recognized figure in the tech community (published author, frequent conference speaker, or open-source contributor).
• AI/ML Infrastructure: Hands-on experience architecting platforms for Generative AI/LLMs. Familiarity with MLOps pipelines, Model Serving and Vector search technologies.
• Legacy Modernisation: Proven success in strangulating monolithic architectures into microservices/serverless patterns without downtime.
