About the role

We are hiring an AI Software Development Engineer in Test II (AI SDET II) — an experienced quality engineer who owns feature-level test strategy and automation for AI-enabled products. In this role, you will design and maintain automated tests and AI evaluation suites, integrate quality signals into CI/CD pipelines, and partner with Scrum teams to prevent defects and deliver reliable AI capabilities.

Key Responsibilities

• Own test strategy and execution for assigned AI features across unit, API, UI, and end-to-end layers, aligned to Definition of Done and release criteria.
• Create and maintain automated AI evaluation suites (including golden datasets, scoring, and regression baselines) covering key user journeys and failure modes.
• Validate prompt, retrieval, and orchestration changes using repeatable test harnesses and defined acceptance thresholds.
• Build and extend automation frameworks, reusable utilities, and improve test stability, speed, and signal-to-noise.
• Integrate automated tests and AI evaluations into CI/CD, triage pipeline failures, and reduce flaky tests.
• Partner with engineers to improve testability (contracts, logging, observability) and drive shift-left quality practices.
• Analyze defects and AI output issues, perform root cause analysis, and implement regression coverage to prevent recurrence.
• Provide guidance to junior SDETs on automation, test design, and AI validation patterns; communicate quality risks to stakeholders.
• Support production readiness by validating guardrails, monitoring signals, and performance requirements for AI features.

Requirements:
• Bachelor’s degree in Computer Science/Engineering (or equivalent practical experience).
• 3+ years of experience in SDET / QA automation / quality engineering with strong hands-on automation and test design skills.
• Proficiency in at least one programming language (e.g., Python, C#, Java) and SQL, with the ability to debug services and tests.
• Experience building and maintaining automated tests (API/UI and/or data/ETL) and working in CI/CD pipelines.
• Experience testing AI-enabled systems or demonstrated applied AI fluency (prompt/RAG changes, evaluation basics, common failure modes).
• Experience working in Agile/Scrum teams and collaborating effectively with Engineering and Product.
• Preferred: Experience with LLM evaluation techniques (golden sets, rubric-based grading, automated scoring, review workflows).
• Preferred: Familiarity with AI safety and guardrail testing (grounding, PII handling, injection risks).
• Preferred: Experience with cloud tooling, containers, observability, and release automation.

Why Join Us

• Build quality systems for real-world AI-enabled products, including LLM evaluations and reliability guardrails.
• Own feature-level quality end-to-end: from test strategy to CI/CD quality gates to production readiness.
• Work with strong cross-functional teams across Engineering, Product, and AI stakeholders in an Agile environment.
• Grow in modern quality engineering practices: observability, automation frameworks, shift-left testing, and AI evaluation patterns.
