Senior QA Automation & Performance Engineer
Location: Bengaluru
Employment Type: Full-time, On-site

About smallest.ai
smallest.ai is building next-generation AI infrastructure and voice technology to power intelligent products at scale. We work across speech, LLMs and real-time AI systems, building products and infrastructure that developers and businesses rely on.
We are looking for a hands-on Senior QA Automation & Performance Engineer to own quality engineering across our backend systems. You will design and build automation frameworks, perform functional and performance testing, and help ensure that our APIs and services remain reliable as traffic, customers and system complexity grow.
This is an individual-contributor role requiring strong technical ownership and close collaboration with engineering, product and infrastructure teams.

What You’ll Do
• Own functional, integration, end-to-end and performance testing for backend services and APIs.

• Design, build and maintain scalable automation frameworks rather than only adding test cases to an existing framework.





• Automate testing across a multi-service, multi-tenant platform.

• Validate tenant isolation, authentication, permissions, configuration differences, data integrity and concurrent tenant activity.

• Design and execute load, stress, spike, scalability and endurance tests.

• Define performance benchmarks and acceptance criteria for latency, throughput, concurrency, reliability and error rates.

• Identify performance bottlenecks and work with backend and infrastructure engineers to resolve them.

• Test business logic, data flows, asynchronous processes, integrations and complete customer workflows.

• Build reusable test utilities, fixtures, test-data strategies and environment-management capabilities.

• Integrate functional and performance test suites into CI/CD pipelines.

• Analyse failures using logs, metrics and traces, and distinguish product defects from workplace or test-framework issu
