Firma i stanowisko

The Validation & Safety Platform is part of the System Health, Validation & Insights Platform group in Productivity Engineering at Netflix. The team focuses on catching safety and correctness regressions in human-written or agent-generated code before it reaches production. They run validation and safety gates for an autonomous agent fleet that writes, tests, refactors, and deploys code continuously across every domain.

Wymagania

Experienced in building and operating platforms used by other engineering teams, with understanding of platform versus API ownership.
Advanced user of agentic coding tools including hooks, MCPs, and context management.
Working knowledge of agent sandboxing, scoping, and data redaction.
Strong communication skills, able to document technical tradeoffs for engineering and non-technical stakeholders.
Advocate for strong testing culture, familiar with test frameworks, code coverage tooling, CI systems, and post-deployment verification.

Nice to have:

Experience designing or operating developer-platform infrastructure like distribution, CI/CD, or versioning systems.
Experience with LLM-based evaluation systems.
Hands-on with mutation testing, static analysis, or test-selection systems at scale.
Experience sandboxing or scoping agent access to sensitive systems or data.

Obowiązki

Design and build validation and safety products used platform-wide: test generation, coverage, safeguards, deterministic and predictive test selection, and mutation testing at scale.
Build the polyglot static analysis layer for automated, language-agnostic quality gating of agent-generated code.
Develop agent-specific safety signals such as detecting prompt flakiness, evaluating agent trajectories against execution traces, and scoring semantic correctness of agent-generated code.
Define clear platform capabilities and make deliberate build-versus-buy, build-versus-extend decisions as the platform evolves.
Apply judgment on agent sandboxing, scoping, and data redaction wherever the platform gives agents access to test infrastructure or execution environments.
