Title: Principal Engineer — Marketing & CRM

Location: Bangalore

Reports to: VP of Engineering


About the Role:

We’re seeking a Principal Engineer to drive the evolution of our cloud-native, SaaS-based marketing and CRM platform serving banks and credit unions across the U.S. The role will focus on technical vision, scalability, re-architecture, and modernization, ensuring the platform is robust, performant, and positioned to scale with our customer base and data growth.


Your Impact:

  • Own the architectural roadmap — evolve our multi-tenant, microservices-based SaaS platform into a scalable, reliable, and extensible product.
  • Define patterns and guardrails for micro frontends, backend services, and API design.
  • Collaborate closely with Product and Engineering Leaders to align technology vision with business goals.
  • Evaluate and introduce new technologies (e.g., event-driven architectures, Kubernetes patterns, ML pipelines, observability frameworks).
  • Mentor and elevate senior engineers, promoting engineering excellence and technical leadership.
  • Drive performance, cost-efficiency, and reliability in data and application layers.
  • Partner with Data Engineering teams leveraging Minerva, Databricks, and PostgreSQL to ensure our platform supports advanced analytics and personalization capabilities.


Key Responsibilities

Architecture & Platform Evolution:

  • Assess current architecture and design a roadmap for scalability, resiliency, and modernization.
  • Champion microservice best practices, including API versioning, service discovery, observability, and CI/CD.
  • Guide micro frontend integration and modular UI composition.
  • Lead technical evaluation for cloud infrastructure, container orchestration, and event streaming (e.g., Kafka, Pub/Sub).

Data & Integration:

  • Ensure seamless integration between transactional and analytical layers (PostgreSQL, Minerva, Databricks).
  • Define data access patterns, caching, and strategies for large-scale, multi-tenant systems.
  • Work with data teams to design real-time data pipelines and support advanced marketing analytics.

Engineering Leadership:

  • Mentor staff and senior engineers; foster a culture of technical rigor and accountability.
  • Conduct architecture reviews, code audits, and performance assessments.
  • Establish best practices for DevOps, CI/CD pipelines, testing automation, and security compliance (SOC 2, FFIEC, etc.).


Tech Stack You’ll Influence

Languages: Java, TypeScript, Python

Frontend: React, Micro Frontends (e.g., Module Federation, Webpack 5)

Backend: Spring Boot

Data: PostgreSQL, Databricks, Minerva, Kafka, Redis

Infra: Kubernetes, Docker, GCP/AWS

DevOps/CI/CD: Jenkins, Terraform

Monitoring: Prometheus, Grafana, OpenTelemetry


Ideal Background:

  • 12+ years of software engineering experience, including at least 4 years in architectural leadership.
  • Proven experience in multi-tenant SaaS platforms (preferably fintech, martech, or CRM domains).
  • Expertise in distributed systems, microservices, and cloud-native architectures.
  • Hands-on understanding of data architecture (OLTP + OLAP integration, streaming, and warehousing).
  • Prior experience with event-driven or CQRS architectures is a plus.
  • Familiarity with banking/financial compliance or data privacy (GLBA, SOC2) is beneficial.
  • Exceptional communication skills and ability to work cross-functionally with product and business stakeholders.
