ByteDance
Senior Software Engineer, AI Infrastructure
About the Team
The Cross‑Platform team at ByteDance is responsible for developing a high‑performance rendering engine and a versatile application framework used across a wide range of products. These systems enable efficient, consistent, and high‑quality UI development at scale. We are expanding our mission to improve developer experience and efficiency by building intelligent development tools that integrate AI and automation.
Responsibilities
Design and implement AI‑powered developer infrastructure that enhances productivity, reduces friction, and improves code quality.
Build and refine intelligent systems for knowledge management, including vector databases, retrieval‑augmented generation (RAG) pipelines, BM25‑based retrieval, and named entity recognition.
Develop and integrate coding agent tools (similar to Codex‑, Claude‑, or Gemini‑style assistants) to support code generation, diagnostics, refactoring, and performance tuning.
Create and maintain evaluation frameworks and benchmarks (e.g., custom test suites like SWE‑bench variants) to rigorously assess AI systems on real‑world coding tasks.
Collaborate with engineers across frameworks and rendering domains to translate pain points into practical, AI‑enhanced solutions.
Maintain infrastructure for model integration, including code analysis, in‑editor assistance, and workflow automation.
Track emerging trends in AI‑assisted development and propose new tools and features that push the boundaries of developer experience.
Minimum Qualifications
Bachelor’s degree in Computer Science, Electrical Engineering, or a related field, or equivalent practical experience.
Strong programming skills in JavaScript/TypeScript, Python, and at least one systems‑level language (e.g., C++, Rust, Go).
Understanding of frontend or cross‑platform application development.
Familiarity with machine‑learning techniques, natural language processing, or large language model (LLM) applications in software tooling.
Preferred Qualifications
Master’s or Ph.D. in Computer Science, Machine Learning, or a related field.
Experience applying AI/ML models to code‑related tasks such as generation, summarization, linting, analysis, or debugging.
Contributions to developer tooling projects (internal or open‑source), especially those focused on code understanding, retrieval systems, or workflow automation.
Knowledge of rendering pipelines or cross‑platform framework architecture.
Experience deploying and optimizing ML models in real‑world production environments.
