QA Manager

NeuBird is scaling rapidly and we need a hands-on QA leader who can build quality into everything we ship while still rolling up their sleeves to write tests and debug complex issues. You'll own quality across our AI-powered DevOps platform while building and mentoring a distributed QA team.

What You'll Do

Lead quality assurance for Hawkeye, our AI SRE agent that helps teams manage and troubleshoot their production environments. You'll design and implement comprehensive test strategies covering UI, integration, and AI-specific testing while building the automation frameworks that let us ship fast without breaking things.

You'll manage a distributed QA team across the US and India, balancing hands-on testing work with coaching and process improvement. This means writing critical test cases yourself, reviewing automation PRs, coordinating testing across time zones, and partnering with engineering to catch issues before they reach customers. You'll own test infrastructure, establish quality metrics that matter, and be the voice of the customer when making tradeoffs between speed and stability.

This role reports to the VP of Engineering and will be instrumental in maintaining our product quality as we scale to aggressive growth targets.

What You Bring

You have 5-7 years in QA with at least 2 years managing QA teams, ideally at a B2B SaaS company building infrastructure or observability tools. You're deeply experienced with UI testing frameworks (Selenium, Cypress, Playwright), integration testing in complex distributed systems, and modern automation frameworks (pytest, Jest, TestNG, or similar). You understand the unique challenges of testing observability tools—metrics pipelines, log aggregation, distributed tracing, and alert systems.

Experience testing AI/ML systems is a strong plus—whether that's model validation, testing non-deterministic outputs, or ensuring AI agent reliability. You've worked with distributed teams across multiple time zones and know how to build processes that work asynchronously. You're comfortable with cloud platforms (AWS preferred), containerization, Kubernetes, and CI/CD pipelines.

More importantly, you're still technical. You can debug a failing test, write automation scripts, and jump into code reviews. You don't just manage—you lead by example. You understand that at a startup, sometimes the best leadership is writing the test that unblocks the team.

Why NeuBird

We're building the next generation of AI-powered DevOps intelligence. Join a well-funded team that's moving fast, shipping constantly, and building something genuinely differentiated in a massive market.
