AI Automation Engineer - Test Generation & Agent Systems (Sr Staff)

Equinix, Inc.; Bengaluru; On-site; INR 4,000,000 - 9,000,000; Full time

Job summary

Equinix, Inc. is seeking a senior engineer to build the intelligence layer of our QE platform, turning Jira tickets or product specs into first-draft Playwright tests via Claude, and an autonomous agent that monitors the live test suite, detects flakiness, diagnoses root causes, and proposes or auto-applies fixes.

You will own the prompt library, define acceptance workflows, measure cost per test and flakiness reductions, and collaborate with automation engineers to handle complex business logic

Qualifications

• Claude/OpenAI API experience with multi-step agent patterns and structured output.
• 8+ years of strong TypeScript or Python experience.
• Ability to rigorously evaluate LLM output with evals.
• Experience designing agentic systems with retries, fallbacks, and human escalation.
• Comfort with ambiguity and building novel solutions in uncharted domains.

Responsibilities

• Design the Claude-powered test generation pipeline: input spec or Jira to first-draft Playwright tests.
• Build the test maintenance agent to monitor, detect flakiness, diagnose causes, and propose fixes.
• Own the prompt engineering layer: maintain the library, evaluation harness, and scoring of tests.
• Define the acceptance workflow for AI-generated tests and determine when to auto-accept.
• Instrument the agent: track cost per test, acceptance rate, time-to-fix, and flakiness reduction.
• Collaborate with automation engineers to handle complex business logic and domain nuance.
• Stay current with fast-moving LLM tooling and evaluate new approaches to improve speed and quality.

Job description

Who are we?

Equinix is the world’s digital infrastructure company®, shortening the path to connectivity to enable the innovations that enrich our work, life and planet. A place where bold ideas are welcomed, human connection is valued, and everyone has the opportunity to shape their future. Help us challenge assumptions, uncover bias, and remove barriers—because progress starts with fresh ideas. You’ll find belonging, purpose, and a team that welcomes you—because when you feel valued, you’re empowered to do your best work.

ABOUT THE ROLE

This is one of the most technically novel roles in the team. You will build the intelligence layer of our QE platform: a pipeline that takes a Jira ticket or product specification and produces a first-draft Playwright test using Claude, and an autonomous agent that monitors the live test suite, detects flakiness, diagnoses root causes, and proposes or applies fixes. The quality of your agent layer will directly determine how fast the rest of the team can move.

WHAT YOU'LL OWN

Design and build the Claude-powered test generation pipeline: product spec or Jira ticket in, first-draft Playwright test out.

Build the test maintenance agent: continuously monitors the suite, detects flaky or failing tests, diagnoses causes, and proposes or auto-applies fixes with human-in-the-loop review.

Own the prompt engineering layer: maintain the prompt library, build an evaluation harness, and score generated test quality systematically.

Define the acceptance workflow: which AI-generated tests require engineer review before merge, and which meet the bar for automatic acceptance.

Instrument the agent layer: track cost per test generated, acceptance rate, time-to-fix for maintenance interventions, and overall flakiness reduction.

Partner closely with automation engineers to understand product domain nuance and improve generation quality for complex business logic.

Stay current with fast-moving LLM tooling and evaluate new approaches that could improve speed or quality.

MUST HAVE

• Production experience with the Anthropic Claude API or OpenAI API — specifically tool use, multi-step agent patterns, and structured output
• 8+ years of Strong TypeScript or Python — comfortable choosing the right language for the task
• Ability to evaluate LLM output quality rigorously: you build evals, not just vibes checks
• Experience designing agentic systems that handle failure gracefully: retries, fallbacks, and human escalation paths
• Comfort with ambiguity and incomplete requirements — you are building something that does not exist yet in most organizations

NICE TO HAVE

• Playwright or comparable E2E test framework experience — you don't need to be an expert but you must be able to read and reason about test code fluently
• Experience with test infrastructure: fixture factories, seed scripts, environment isolation
• Prior work building agents with persistent memory, multi-tool orchestration, or complex retry logic
