Software Engineer - Compiler Developer Productivity Engineer

About the RoleAt Furiosa AI, we are committed to enhancing the productivity of our compiler team by systematically designing and continuously improving our CI and development workflows.In this role, you will focus on transforming CI into a more reliable, efficient, and user-friendly system through the development of developer productivity tools, including CI orchestrators.Our compiler team executes large-scale tests across multiple clusters to optimize model performance in terms of both time and energy. Within this context, CI operates not merely as a pipeline executor but as a sophisticated orchestration system that coordinates complex workloads and resources, demanding high reliability and automated recovery capabilities.Aim for engineering that defines and resolves problems rather than simple operations.Engineers are encouraged to analyze issues independently and propose improvement directions.Important decisions are made collaboratively within the team.Improve both development productivity and stability through practical approaches.

Role overview The Compiler team at FuriosaAI builds the software stack that enables machine learning models to run efficiently on the company’s AI accelerator hardware. This Software Engineer - Compiler (AX Engineer) role is a new position based at the Seoul headquarters. The focus is on developing and refining AI-assisted engineering workflows, identifying bottlenecks, running experiments, and building tools and guides that the team can use repeatedly. While the role is part of the Compiler team, deep compiler expertise is not required. Daily work includes code reviews, debugging, CI and testing, documentation, and project management. This position is a good fit for someone who enjoys shaping new roles and working through open-ended challenges. What you will do Identify challenges and opportunities in engineering workflows, including development, code review, debugging, CI/testing, documentation, and project delivery. Research, prototype, and benchmark AI and automation tools, such as coding agents, LLM-assisted reviews, and debugging assistants, using real team workflows. Create and maintain prompt libraries, workflow templates, and integration guides tailored to team needs. Improve CI/testing feedback and signals with the goal of reducing flaky tests and streamlining failure triage. Lead onboarding sessions and regular Q&A meetings to share knowledge about new tools. Define and track metrics like PR cycle time, review turnaround, regression triage time, and CI flakiness, iterating based on findings and team feedback. Stay current on developments in the AI tooling ecosystem and keep the team informed about relevant updates. Requirements At least 3 years of experience in software engineering. Hands-on experience with LLM-based coding tools (such as GitHub Copilot, Cursor, Claude Code, or Codex). Strong understanding of software development workflows from an engineer’s perspective. Ability to quickly evaluate new tools and provide practical guidance to the team. Preferred qualifications Bachelor’s degree in Computer Science or a related field.

About the RoleAt FuriosaAI, we are dedicated to advancing high-performance and energy-efficient AI systems through our innovative compiler technology. As deep learning models continue to diversify and evolve, the challenges of compilation become more complex. Our mission revolves around transforming these models into optimized executable programs while ensuring the integrity of their meaning and structure.We believe in establishing robust abstractions and well-organized compiler logic instead of relying solely on heuristics. This foundational approach ensures consistency in correctness, scalability, and performance throughout the compiler.In your role as a middle-end engineer, you will significantly influence the design of these abstractions and the operational framework of the compiler. This position demands a blend of analytical reasoning and innovative problem-solving to navigate the intricate challenges of compilation. Your contributions will be vital in creating a compiler that is both principled and pragmatic.
