Role

We are looking for a Principal Software Engineer to join our team. This is a hybrid role based in Mohali/India, reporting to the Director, Software Engineering within the Shared Platform Services department. As a technical leader, you will drive the evolution of our platform by designing and building scalable, high-performance microservices. You will bridge the gap between architectural vision and hands-on execution to deliver robust APIs that power our global infrastructure.

What you’ll do (Role Expectations)

Develop high-quality, performant, and secure APIs and microservices that are reusable and extensible
Collaborate with front-end engineers to define and deliver endpoints for high-quality user interfaces
Lead DevOps initiatives including continuous integration, provisioning, and software version control
Design and extend in-house APIs and client-side code using RESTful standards and SDKs
Drive strategic contributions to system design and long-term platform architecture

Who You Are (Success Profile)

You thrive in ambiguity. You're comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful.
You act like an owner. Your passion for the mission fuels your bias for action. You operate with integrity because you genuinely care about the outcome. True ownership involves leveraging dynamic range: the ability to navigate seamlessly between high-level strategy and hands-on execution.
You are a problem-solver. You love running towards the challenges because you are laser-focused on finding the solution, knowing that solving the hard problems delivers the biggest impact.
You are a high-trust collaborator. You are ambitious for the team, not just yourself. You embrace our challenge culture by giving and receiving ongoing feedback—knowing that candor delivered with clarity and respect is the truest form of teamwork and the fastest way to earn trust.
You are a learner. You have a true growth mindset and are obsessed with your own development, actively seeking feedback to become a better partner and a stronger teammate. You love what you do and you do it with purpose.

What We’re Looking for (Minimum Qualifications)

Deep expertise in hands-on software application development for complex, large-scale systems
Proficiency with Quarkus (Mutiny) and Spring (Webflux) reactive frameworks
Experience building cloud-native distributed applications with Dapr and Kubernetes
Background in containerized deployment using Docker and Kubernetes on AWS, GCP, or similar cloud providers
Ability to work independently and pivot quickly in a fast-paced Agile environment
