Cloud Platform Architect – AWS SaaS Platform

Location: Bengaluru

Experience: 12–18 Years

Role Type: Full-Time

Role Overview

We are seeking a senior Cloud Platform Architect to own and steward the architecture of MOBIUS+, an AWS-based SaaS product platform.

The role will serve as the technical authority for platform architecture, ensuring the platform remains scalable, secure, resilient, extensible, and cost-efficient as the product and its ecosystem evolve.

The ideal candidate will combine deep technical expertise with robust architectural leadership and product thinking to define platform direction, establish engineering standards, and ensure architectural decisions translate into high-quality implementation.

Key Responsibilities

1. Platform Architecture & Strategy

- Own the end-to-end platform architecture, target state, and architecture roadmap.
- Define architecture principles, reference patterns, engineering guardrails, and Architecture Decision Records (ADRs).
- Architect a modular and evolvable platform with clear boundaries across product capabilities, integrations, data, and infrastructure.
- Identify and manage architecture risks, technical debt, and platform evolution priorities.
- Ensure architectural decisions support long-term product scalability and maintainability.

2. Multi-Tenant SaaS Architecture

- Define and govern multi-tenant architecture, including tenant isolation, identity, data segregation, configuration, and tenant lifecycle management.
- Support multi-tenant SaaS and dedicated customer deployments while maintaining a coherent product architecture and unified codebase.
- Establish architectural patterns for secure tenant onboarding, access control, and resource management.
- Ensure tenant isolation and security across application, data, and infrastructure layers.

3. API-First & Event-Driven Architecture

- Define API-first and event-driven architecture, including API governance, versioning, integration, and extensibility patterns.
- Establish modular architecture and microservices design principles.
- Define integration patterns for product capabilities, external systems, and ecosystem partners.
- Ensure reliable communication, interoperability, and scalability across platform services.

4. Cloud Architecture,



Security & Reliability

- Own key non-functional architecture requirements covering security, scalability, availability, resilience, performance, observability, and disaster recovery.
- Drive effective use of AWS cloud-native and managed services, balancing scalability, operational efficiency, and cost.
- Establish cloud security standards and best practices for identity and access management, networking, and infrastructure protection.
- Define high availability, disaster recovery, fault tolerance, and business continuity strategies.
- Drive cloud cost optimization and efficient resource utilization.

5. Architecture Governance & Engineering Excellence

- Review significant solution designs and ensure implementation conforms to agreed architecture principles and engineering guardrails.
- Establish architecture governance practices, technical standards, and design review processes.
- Evaluate architectural trade-offs and communicate decisions through clear architecture models and ADRs.
- Promote Infrastructure as Code (IaC), CI/CD, and modern DevSecOps practices.
- Encourage AI-enabled software engineering and modern engineering productivity practices.

6. Technical Leadership & Collaboration

- Work closely with Product Management and Engineering teams to translate product strategy and roadmap into sustainable platform capabilities.
- Provide technical leadership and architecture guidance across engineering teams.
- Build architecture capability and promote sound architectural practices throughout the organization.
- Mentor engineers and technical leaders on architecture, design principles, and engineering best practices.
- Remain closely involved in implementation to ensure architectural decisions deliver practical, high-quality outcomes.

Required Experience & Skills

- 12–18 years of software engineering and architecture experience,



supported by a strong hands-on engineering foundation.
- Proven experience architecting and evolving large-scale SaaS or product platforms on AWS.
- Deep understanding of multi-tenancy and tenant-isolation patterns across application, data, and infrastructure layers.
- Strong AWS architecture knowledge across:
- Compute and serverless services
- Identity and Access Management (IAM)
- Networking and security
- Databases and storage
- Messaging and event-driven services
- Monitoring, logging, and observability

- Strong experience with API-driven, modular, microservices, and event-driven architectures.
- Strong understanding of cloud security, scalability, resilience, high availability, disaster recovery, performance optimization, and observability.
- Experience with Infrastructure as Code, CI/CD pipelines, and modern DevSecOps practices.
- Ability to evaluate architectural trade-offs and communicate decisions through clear architecture models and ADRs.
- Demonstrated ability to provide technical leadership and architecture governance across engineering teams.
- Experience with AI-enabled software engineering and modern engineering productivity practices.

Preferred Qualifications

- Experience with serverless-first AWS architecture.
- Knowledge of platform engineering and developer experience practices.
- Experience evolving enterprise platforms over long product lifecycles.
- Experience with FinOps, cloud cost optimization, and resource governance.
- Experience designing secure, scalable, and extensible enterprise SaaS platforms.

What We Look For

We are looking for a builder-architect with strong technical depth, a product-oriented mindset, and the ability to balance architectural vision with practical engineering execution.

The successful candidate will be able to establish architecture direction, challenge designs, make pragmatic trade-offs, and remain sufficiently close to engineering to ensure architectural decisions translate into high-quality implementation.

They will play a key role in ensuring the platform evolves into a secure, scalable, resilient, and cost-efficient SaaS ecosystem while establishing strong architectural practices across engineering teams.
