Sony Interactive Entertainment Sony Interactive Entertainment is hiring a Staff Software Engineer to build AI-powered tools and integrations for game engines, editors, clients, and backend services. The role involves delivering high-quality C++ integrations and collaborating with multiple PlayStation Studios teams.

Responsibilities

We’re looking for a Staff Software Engineer to build AI-powered tools and integrations that plug directly into game engines, editors, clients, and backend services. You’ll deliver high-quality C++ integrations across proprietary studio engines, ship robust build/QA automation, and partner with multiple PlayStation Studios teams to make AI an everyday part of development.
Build and maintain engine/editor plugins, runtime SDKs, and services that integrate AI (LLMs and related systems) into game clients, servers, and build tools.
Ship performant, memory-aware C++ by profiling, optimizing, and debugging across PC/console builds with tight frame budgets.
Design stable API surfaces for game teams (C++/C API, gRPC/HTTP) with versioning, telemetry, and backward compatibility.
Stand up CI/CD for game builds and tools (UBT or proprietary build systems; artifact packaging; nightly/regression suites; distributed/accelerated builds).
Automate QA for tooling and in-engine features using engine test frameworks and headless runs, and wire results into CI and dashboards.
Implement production LLM integrations (prompting, RAG/tool calls, guardrails/safety, observability, timeouts/retries, and cost controls).
Collaborate with studio engineering, tech art, design, and QA to land integrations across varied codebases and pipelines.
Document patterns, provide sample projects, and deliver internal training so solutions scale across PlayStation Studios.
Influence standards and tech choices for AI in our dev stack, and contribute to shared libraries and best practices.
