Job summary

ByteDance PTE. LTD. (Volcano Ark) seeks graduates to help build the next-generation Agent infrastructure for the Volcano Ark platform, designing a scalable runtime and execution engine for complex tasks.

You will contribute to resource modeling, lifecycle management, and configuration, while enabling external OpenAPIs and integration with leading agent harnesses. Strong coding skills and Linux/container experience are required.

Qualifications

• Bachelor's or Master's degree in computing or a related discipline.
• Solid coding skills and system design capabilities.
• Proficient in at least one of Golang, Python, Rust, or Java, with hands-on experience using AI-powered coding tools.
• Strong understanding of large language models and Agent architectures, including tool calling, context management, long-horizon execution, and self-invocation.
• Candidates with hands-on experience building production Agent systems or extensive experience using coding agents such as Claude Code, Codex, or Cursor are preferred.
• Familiar with Linux, container technologies (Docker, Kubernetes), and cloud-native infrastructure.
• Understanding of distributed systems, task scheduling, observability, resource isolation, and network access control. Experience with declarative APIs, the Kubernetes controller pattern, and Operator/CRD development is a plus.
• Backend & Distributed Services: Experienced in microservice architecture and common backend technologies such as MySQL, Redis, and message queues.
• Strong API design and data modeling skills. Experience designing and optimizing high-concurrency, low-latency online services is preferred.
• Preferred: familiar with container runtime, virtualization technologies, serverless platforms, multi-tenant systems, or large-scale data storage and retrieval systems.
• Passionate about AI-native applications and staying current with the latest advancements in Agent technologies.

Responsibilities

• Develop the core Agent infrastructure for the Volcano Ark platform by designing and implementing a highly reliable, scalable Agent runtime and execution engine.
• Improve execution efficiency, security, and stability while building a general-purpose Agent infrastructure capable of supporting complex tasks.
• Build core platform capabilities, including resource model abstraction, lifecycle management, and configuration management. Integrate with the Volcano Engine.
• Open Platform to deliver external-facing OpenAPIs, covering API registration, publishing, authentication, rate limiting, and metering & billing, ensuring reliability, compatibility, and operational stability.
• Design and develop the Agent evaluation framework by integrating industry-standard benchmarks. Enable compatibility with leading Agent harnesses including Claude Code, Codex, and OpenCode, while building a unified integration layer and execution protocol.
• Develop capabilities for metrics collection, trace replay, bad‑case analysis, and cost/latency analytics to continuously improve the platform.
• Ensure the quality of online services under high-concurrency and large-scale workloads by building robust performance optimization, reliability, and observability capabilities across the Agent platform.
• Stay at the forefront of Agent technologies and AI-native applications by exploring next-generation Agent paradigms.
• Drive the productization of platform capabilities to improve developer productivity, while serving as a power user of the Agent platform to continuously refine and enhance its core capabilities through real-world feedback.
