Principal Software Engineer, Agent Policy Fabric

Position Overview

NVIDIA's Cloud Engineering & Services team is seeking a Principal Software Engineer for the Agent Policy Fabric (APF) Core Platform. The candidate will mature APF v0 proof‑of‑life into a robust core platform to enable governed agent action.

• Own APF Core Services: build and harden the Runtime Policy Verifier, signed policy bundle verification, trust‑root handling, freshness, rollback protection, subject binding to attested runtime context, revocation checks, and authorization APIs used by APF‑compatible enforcement points.
• Design Policy Projection: implement deterministic projections from the canonical APF policy into Open Shell‑native runtime policy, adapter constraints, credential constraints, audit requirements, and model‑visible tool hints while preserving the atomic projection‑admission contract.
• Build Conformance and Verification: create golden fixtures, compatibility tests, negative tests, fuzz/property tests, and conformance suites that prove APF‑compatible runtimes and adapters honor the same contract.
• Collaborate with Runtime Owners: work with Open Shell and Infrastructure engineers on public runtime interfaces for projection consumption, runtime context attestation, approved adapter paths, direct egress verification, and admission/rejection semantics.
• Land the Runtime integration surfaces: drive cross‑team work with Open Shell and other runtime owners to land public substrate interfaces APF composes against – runtime‑context attestation, approved adapter path declaration, projection acceptance and rejection semantics, quarantine, and stop‑session hooks. Land each as a public RFC or PR.
• Drive Architecture Maturity: define versioning, schema compatibility, latency budgets, availability behavior, fail‑closed defaults, last‑known‑good policy handling, and engineering review artifacts for Product Security, Fleet, Identity, and partner teams.
• Evolve technical specifications: write specifications, defend bounded claims in security and architecture reviews, drive open‑decision resolution, and turn working‑draft contracts into engineering artifacts that Product Security, Fleet, Identity, and partner runtimes can adopt.

• Bachelor's degree (or equivalent experience) with 15+ years of industry experience in systems software, security engineering, distributed systems, or policy infrastructure.
• Strong programming skills in Rust, Go, C++, or Python; experience designing production services, APIs, schemas, policy engines, authorization systems, or signed artifact pipelines.
• Linux systems, IPC or service‑to‑service APIs, protobuf/gRPC or equivalent wire formats, CI, test automation, release engineering, and cloud or enterprise deployment environments.
• Practical experience with authorization, cryptographic signatures, trust roots, revocation, subject binding, rollback protection, secure‑by‑default failure handling, and zero‑trust architecture patterns.
• Architectural leadership: ability to write streamlined technical specifications, align multiple engineering owners, defend bounded claims, and turn working‑draft architecture into buildable interfaces without over‑scoping the runtime.

• Runtime Policy Systems: experience with OPA/Rego, Cedar, Zanzibar‑style authorization, policy compilers, sandbox policy, or runtime enforcement systems.
• Agent Runtime Security: familiarity with agent frameworks, tool‑call governance, sandboxed execution, Open Shell‑like runtime substrates, MCP‑style tool routing, or credential isolation for agents.
• Supply Chain and Signing: experience with Sigstore, TUF, in‑toto, HSM‑backed signing, package provenance, signed configuration, or enterprise trust‑root distribution.
• Formal or Adversarial Verification: experience using property testing, model checking, symbolic execution, red‑team findings, or bounded verification to constrain security claims.
• Standards engagement: experience contributing to RFCs in identity, supply‑chain, or policy spaces (IETF, OpenID Foundation, FIDO Alliance, CNCF, NIST).
