Axle is seeking a Junior Software Engineer with a solid foundation in C++ and a genuine enthusiasm for LLM-based development workflows. This role sits at the intersection of traditional high-performance software engineering and the rapidly evolving landscape of AI-assisted coding tools and large language model (LLM) integration.

You will work as part of a collaborative, cross‑functional team building scalable software systems for compute‑intensive research environments. A key part of your day‑to‑day will involve leveraging LLM‑based tools—such as AI coding assistants, prompt‑driven code generation, and LLM‑integrated pipelines—to accelerate development and explore novel solutions to engineering challenges.

• Develop and maintain C++ software components for scientific and computational workloads, with a focus on correctness and maintainability.
• Integrate and leverage LLM‑based tools (e.g., Git Hub Copilot, Claude, GPT‑4) throughout the development lifecycle—from code generation and review to documentation and debugging.
• Build and experiment with LLM‑assisted pipelines for automating repetitive engineering tasks, code scaffolding, and developer productivity tooling.
• Collaborate with senior engineers and researchers to prototype and evaluate LLM‑integrated solutions to complex software problems.
• Contribute to testing, CI/CD workflows, and code documentation—using AI tools to maintain quality and delivery speed.
• Stay current with the fast‑moving LLM tooling ecosystem and proactively share learnings with the team.

Note: Some projects involve image‑based data and scientific computing workflows. Prior expertise in these areas is not required; you will develop this knowledge with support from the team.

• 1–3 years of professional experience (or equivalent academic/research experience) in software development.
• Working knowledge of C++, including comfort reading, debugging, and contributing to C++ codebases.
• Demonstrated experience using LLM‑based development tools (e.g., Copilot, Cursor, Claude, ChatGPT) as part of a regular development workflow.
• Familiarity with prompt engineering concepts and an understanding of how to effectively direct LLMs for code generation, review, or explanation tasks.
• Working knowledge of Linux development environments.
• Basic experience with Python for scripting, tooling, or working with LLM APIs (e.g., OpenAI, Anthropic).
• Strong problem‑solving skills and eagerness to learn within a fast‑evolving technical landscape.

• Experience building or integrating LLM‑powered features into applications or developer tooling (e.g., RAG pipelines, tool‑calling agents, code‑aware assistants).
• Familiarity with LLM APIs (OpenAI, Anthropic, Hugging Face) or open‑source models (LLaMA, Mistral).
• Understanding of modern C++ (17/20) idioms and experience with performance‑oriented development.
• Exposure to scientific computing, numerical methods, or high‑performance computing concepts.
• Experience with parallel computing concepts (multithreading, vectorization, OpenMP).
• Familiarity with modern build systems (CMake, Bazel) and container technologies (Docker).
• Interest in evaluating and benchmarking LLM output quality for engineering tasks.

• Curiosity about LLM‑assisted development and a desire to push the frontier of AI‑augmented…
