Principle Performance Engineer

Location: Hyderabad

Duration: Fulltime / Permanent

We re seeking a Senior Developer Experience (DevX) Engineer to help evolve and elevate the development patterns, frameworks, and practices that power our engineering organization. In this role, youll be a key contributor to an established platform - refining what works, optimizing what can be better, and guiding our teams toward engineering excellence at scale.

About the Role:

We re seeking a Senior Engineer with a deep understanding of Azure SQL and C# to help us take our already successful system to the next level of performance and maintainability. This role isn t about fixing a broken system far from it. Our platform is stable, performant, and used by thousands daily. But we believe there s always room for improvement and our growth is causing us to focus on efficiency and scalability.

This is a high-impact, strategic role focused on identifying and eliminating inefficiencies that have crept into our architecture over time - specifically in how our C# application interacts with our Azure SQL database. You ll lead the charge in removing unnecessary stored procedures, redesigning overly complex or inefficient schemas, and modernizing data access patterns to better align with our current and future needs.

The successful candidate will not only be able to find opportunities for improvement, but will be able to understand how those fit into a larger architecture and how they can be implemented without introducing defects or downtime in our 24x7 system. You will be a driven self-starter who will take ownership of problems from investigation to resolution. Moreover, you will do this while partnering with other senior engineering leaders to share both their knowledge of what has been done (and why) and your knowledge of what can be done.

What You ll Do

Leverage end-to-end visibility of the C# codebase, Azure SQL database, and key metrics to identify performance and maintainability bottlenecks.

Act as a subject matter expert for the migration from stored procedures to mid-tier implementations.

Conduct deep system investigations to uncover opportunities for improvement, including but not limited to:

o Poorly structured or legacy database schemas

o Inefficient data access or duplication patterns

Collaborate across engineering, DevSecOps, and data teams to create actionable remediation plans and drive those plans through the SDLC process to production.

Act as a change agent, championing modern best practices in database design and code integration.

Produce and present detailed findings and plans to technical stakeholders and leadership.

Maintain a balance between ideal solutions and pragmatic tradeoffs to keep the system stable while evolving it.

Mentor and influence engineering teams without direct ownership of the code, relying on thought leadership and communication.

What We re Looking For

7+ years of software engineering experience, with significant hands-on expertise in C# and .NET Core.

Proven experience working with Azure SQL or comparable relational database systems in high-throughput environments.

A strong understanding of database normalization, indexing strategies, and modern data access patterns (e.g., ORM best practices).

Experience identifying performance issues through profiling tools, logs, and SQL execution plans.

A holistic systems thinker who can comfortably jump between application and database layers.

A track record of leading architectural improvement initiatives across teams or organizations.

Excellent communication and interpersonal skills - you know how to drive change without direct authority.

Why You ll Love Working Here

Work on a system that s already working well - and help make it even better.

Collaborate with teams who value thoughtful engineering, technical rigor, and clean architecture.

Be empowered to make a real difference through strategic guidance and technical insight.

Join a culture that values long-term thinking, knowledge sharing, and continuous improvement.

Ready to join a team that values thoughtful engineering and believes that good systems can always be betterWe d love to hear from you.
