Axle is seeking a Junior Software Engineer with a strong foundation in C++ and scientific computing to help build and optimize high‑performance software systems used in compute‑intensive research environments. This role focuses on core software engineering and performance‑oriented C++ development within Linux and HPC settings.

You will work as part of a collaborative, cross‑functional team developing scalable, well‑engineered systems for numerical and data‑intensive workloads. While some projects involve image‑based data, prior image processing experience is not required—you will learn these domain‑specific aspects on the job with support from senior engineers and domain experts.

Key Responsibilities

• Design, develop, and maintain high‑performance C++ software for scientific and computational workloads.

• Build scalable applications using modern C++ (17/20) with an emphasis on correctness, performance, and maintainability.

• Develop and extend scientific computing pipelines running in Linux and HPC environments.

• Optimize compute‑intensive code using profiling, benchmarking, and performance‑tuning techniques. Collaborate with senior engineers and researchers to translate computational requirements into robust software solutions.

• Work with containerized applications (Docker, Singularity) deployed in HPC and cloud environments.

• Integrate applications with HPC schedulers (e.g., Slurm) for batch and interactive workloads.

• Contribute to documentation, testing, and CI/CD workflows to support reliable software delivery.

Required Skills & Qualifications

• 1–3 years of professional experience (or equivalent academic/research experience) in software development.

• Proficiency in C++ for scientific or performance‑critical applications.

• Working knowledge of Linux development environments.

• Familiarity with modern build systems (e.g., CMake, Bazel).

• Experience or coursework in scientific computing, numerical methods, or systems programming.

• Basic experience with Python for scripting, tooling, or analysis.

• Strong problem‑solving skills and a desire to learn complex technical systems.

Preferred Qualifications

• Exposure to parallel or high‑performance computing concepts (e.g., multithreading, vectorization, MPI, OpenMP).

• Experience with GPU computing (CUDA, etc.)

• Experience running software on HPC clusters or similar shared compute environments.

• Familiarity with container technologies (Docker, Singularity).

• Experience with profiling or performance‑analysis tools.

• Interest in applied scientific or research‑driven software development.

What We Emphasize

• Strong fundamentals in C++ and software engineering

• Learning and growth over prior domain specialization

• Mentorship and collaboration with experienced engineers

• Clear ownership of well‑scoped technical components
