About the role

Key responsibilities & impact

Design and build platform-level test infrastructure for iOS and Android that runs continuously, scales automatically, and surfaces signals without human intervention.
Apply AI-driven failure classification to reduce noise, prioritize signal, and cut time-to-fix on test failures across mobile suites.
Partner with the AI Native platform team to ship net-new skills that replace categories of manual engineering work.
Build and maintain in-app instrumentation for mobile performance, quality signal, and test execution telemetry.
Design data pipelines that feed quality signals into dashboards, alert systems, and AI analysis layers, providing the org with real-time visibility into test health and app quality.
Own the infrastructure used to baseline, monitor, and debug mobile API behavior in CI.
Partner with Mobile, Backend, and Release Engineering teams to embed AI-native quality practices throughout the development lifecycle — from intent to production.
Contribute to the design and rollout of agentic quality automation: systems that act on quality signals rather than just report them.
Raise the pod’s AI-native capability — documenting what works, improving shared workflows, and helping others develop the judgment to direct AI effectively.

Requirements

What you’ll need

A track record of delivering complex, production-grade software outcomes.
Genuine fluency directing AI agents: you decompose, delegate, and validate at a level that produces better output than most engineers produce writing manually.
Comfort working across the stack — mobile instrumentation, backend pipelines, CI/CD systems, and developer tooling — without needing to stay in one lane or waiting for someone else to own a layer. AI closes the skill gaps; you provide the judgment.
The ability to make good decisions quickly under ambiguity, and to distinguish reversible decisions (ship it) from irreversible ones (slow down).
Judgment on AI-generated artifacts — you know what good looks like, catch what is locally correct but globally brittle, and hold a consistent quality bar regardless of how code was produced.
The ability to frame problems with precision — your prompts, specs, and plans are clear enough that AI can act on them without constant correction.
Experience with MCP (Model Context Protocol), LLM tool use, or agent orchestration frameworks (LangChain, LangGraph, AWS Bedrock Agents, etc.).
Clear, direct communication with engineers, product teams, and stakeholders across the org.
Bachelor’s degree or equivalent.
