Senior Python Software Engineer information

What does a senior Python software engineer do?

A Senior Python Software Engineer designs, develops, tests, and maintains complex software applications using the Python programming language. They often lead or mentor junior developers, architect software solutions, and ensure best coding practices are followed. These professionals collaborate with cross-functional teams to deliver scalable and efficient systems, troubleshoot issues, and optimize application performance. Their expertise includes advanced knowledge of Python frameworks, libraries, and development tools, as well as experience with databases, APIs, and cloud services.

What are the key skills and qualifications needed to thrive as a senior Python software engineer?

To thrive as a Senior Python Software Engineer, you need advanced proficiency in Python programming, strong problem-solving abilities, and a solid background in computer science or a related field. Familiarity with frameworks like Django or Flask, experience with version control systems such as Git, and knowledge of cloud platforms and CI/CD tools are typically required. Leadership, effective communication, and mentorship skills help you collaborate with teams and guide junior developers. These skills ensure the delivery of robust, scalable software solutions and foster a productive, innovative development environment.

What are some common challenges faced by senior Python software engineers when leading complex projects, and how can they be addressed?

Senior Python Software Engineers often face challenges such as balancing hands-on coding with mentoring junior team members, managing technical debt, and designing scalable solutions. Successfully addressing these challenges involves clear communication, proactive code reviews, and effective prioritization of tasks. Collaborating closely with cross-functional teams and fostering a culture of knowledge sharing can also help ensure project success and team growth.

What is the difference between Senior Python Software Engineer vs Python Developer?

AspectSenior Python Software EngineerPython Developer
Required CredentialsBachelor's degree in CS or related field, experience in software engineeringBachelor's degree in CS or related field, coding proficiency

Job description

NVIDIA's accelerated computing platform is foundational to modern HPC and AI. At the center of this platform are CUDA Core Libraries that enable developers to build fast, reliable, and scalable GPU-accelerated software.

We are hiring a Senior Software Engineer to advance the Python experience for CUDA Core Libraries. You will build Pythonic APIs, language bindings, algorithms, and runtime infrastructure on top of native C/C++ foundations. You will join the team building the foundational libraries, algorithms, and language/runtime infrastructure that make CUDA a speed-of-light experience for developers and AI coding agents alike.

What you'll be doing:

  • Design and implement idiomatic Python APIs and bindings for foundational CUDA capabilities and GPU algorithms.

  • Develop and integrate the native C/C++ components that support Python-facing functionality.

  • Define reliable and efficient interoperability boundaries between Python, C/C++, Rust, and other languages.

  • Develop high-performance interfaces that minimize Python and native-language integration overhead.

  • Own features throughout their lifecycle: design, implementation, testing, profiling, benchmarking, documentation, release, and long-term maintenance.

  • Improve the Python developer experience through typing, packaging, examples, diagnostics, continuous integration, and compatibility testing.

  • Collaborate with C/C++, Rust, compiler, and runtime engineers on shared architecture and API decisions.

  • Work directly with users to investigate correctness, usability, compatibility, and performance issues.

What we need to see:

  • BS, MS, or PhD in Computer Science, Computer Engineering, or a related field, or equivalent experience.

  • 8+ years of relevant software-development experience.

  • Strong production programming skills in both Python and C/C++; both are required for this role.

  • Experience building Python interfaces to native or systems-level software.

  • Understanding of systems software concepts, performance, concurrency, and API design.

  • Practical experience with parallel, heterogeneous, or GPU programming.

  • Experience developing production software or widely used libraries, including testing, profiling, benchmarking, packaging, and code review.

  • Ability to work independently, define project scope, and drive complex work to completion.

  • Clear written communication skills for API specifications, technical designs, and user documentation.

  • Comfort working in large codebases spanning Python, C/C++, build systems, packaging, and continuous-integration infrastructure.

Ways to stand out from the crowd:

  • Strong understanding of CPU/GPU architecture and performance optimization, with hands-on experience in GPU-accelerated stacks (CUDA C++/Python, PyTorch, JAX, Numba, CuPy, or similar).

  • Proficiency with modern C++ and GPU libraries such as Thrust, CUB, and libcudacxx.

  • Experience with compiler infrastructure and tooling, including LLVM, Clang, or MLIR.

  • Expertise in designing low-overhead interoperability between Python and native languages, including exposure to Rust in mixed-language stacks.

  • Demonstrated interest in developer tools, library design, and improving developer productivity.

Your base salary will be determined based on your location, experience, and the pay of employees in similar positions. The base salary range is 184,000 USD - 287,500 USD for Level 4, and 224,000 USD - 356,500 USD for Level 5.

You will also be eligible for equity and benefits.

Applications for this job will be accepted at least until July 25, 2026.
