Role

We are looking for a Senior Software Development Engineer to join our Platform & Reliability Engineering department in Bangalore, reporting to the Director of Platform & Reliability Engineering. In this role, you will play a key role in ensuring the quality, scalability, and reliability of ZDX solutions. You will lead automation initiatives to build robust frameworks, validate feature functionality, optimize system performance, and champion an AI-first approach to development. This is an exciting opportunity to contribute to cloud-based systems that process large volumes of data while delivering world-class user experiences.

What you’ll do (Role Expectations)

Design and develop scalable, reusable, and maintainable test automation frameworks using an AI-first development methodology
Develop and execute end-to-end tests to ensure seamless operation of ZDX components, including cloud services, analytics dashboards, APIs, and user-facing applications
Collaborate with engineering and DevOps teams to integrate testing pipelines into CI/CD workflows, ensuring faster release cycles without compromising quality
Utilize analytics tools, logs, and testing outputs to identify bottlenecks and troubleshoot issues systematically
Continuously refine testing methodologies to improve coverage, detect issues earlier, and maximize efficiency

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)

Foundational understanding of AI/ML technologies and experience leveraging, securing, or positioning AI-driven solutions to optimize outcomes within your functional domain
4+ years of experience in automation testing, preferably within cloud or SaaS environments
Proficiency in programming languages such as Python, Java, or JavaScript for building automation and testing solutions, alongside familiarity with testing tools and performance analysis
Experience with cloud platforms including AWS, Azure, or Google Cloud alongside containerization technologies like Docker and Kubernetes
Experience integrating testing workflows into CI/CD pipelines using tools such as Jenkins, GitLab CI, or similar systems

What Will Make You Stand Out (Preferred Qualifications)

Familiarity with various testing methodologies, automation frameworks, and infrastructure-as-code (IaC) tools
Good understanding of data platforms, SQL, and ETL frameworks to support scalable data ingestion, transformation, and querying
Solid understanding of networking protocols, diagnostic tools like Wireshark or TCPDump
