Senior Machine Learning Engineer

At Axon, we’re on a mission to Protect Life. We’re explorers, pursuing society’s most critical safety and justice issues with our ecosystem of devices and cloud software. Like our products, we work better together. We connect with candor and care, seeking out diverse perspectives from our customers, communities and each other.

Life at Axon is fast-paced, challenging and meaningful. Here, you’ll take ownership and drive real change. Constantly grow as you work hard for a mission that matters at a company where you matter.

• →Design and implement high-performance C++ software that runs computer vision and tracking algorithms in real time on edge devices.
• →Work closely with computer vision / self-supervised learning engineers to integrate their models into production pipelines, including pre/post-processing, I/O, and system orchestration.
• →Build and optimize multithreaded and parallel processing pipelines for ingesting, synchronizing, and processing data from a networked system of cameras.
• →Implement and tune CUDA kernels and GPU-accelerated components to maximize throughput and minimize latency for inference, tracking, and search.
• →Design robust data structures and memory management strategies for handling large volumes of video, sensor, and metadata streams under tight compute and power constraints.
• →Profile and optimize code using tools such as perf, valgrind, nvprof / Nsight, and similar to identify bottlenecks and improve CPU/GPU utilization.
• →Collaborate with simulation and CV teams to deploy and evaluate algorithms in realistic test scenarios, including fault handling and performance monitoring.
• →Develop clean, well-tested, and well-documented C++ libraries and services that can be reused across products and future airspace applications.
• →Contribute to system-level architecture decisions, including inter-process communication, scheduling, resource allocation, and deployment strategies on edge platforms.

• 5+ years of professional experience in modern C++ (C++14/17 or later), with strong object-oriented and generic programming skills.
• Deep understanding of multithreading and concurrency (threads, thread pools, locks, lock-free structures, atomics, futures, async patterns) and experience building robust, concurrent systems.
• Hands-on experience with parallel processing frameworks or patterns (SIMD, task-based parallelism, GPU offload, or similar) for real-time or high-throughput applications.
• Strong command of data structures and algorithms, and the ability to choose and implement the right structures for performance-critical, memory-constrained environments.
• Proven experience with memory management and performance optimization in C++ (stack vs heap, custom allocators, cache-aware design, avoiding fragmentation, RAII, move semantics).
• Practical experience with CUDA (or similar GPU programming frameworks): writing kernels, managing GPU memory, optimizing for occupancy and bandwidth, and integrating with C++ codebases.
• Experience integrating machine learning or computer vision inference engines (e.g., TensorRT, OpenVINO, ONNX Runtime) is a strong plus.
• Familiarity with Linux-based development (build systems like CMake, unit testing frameworks, containerization and/or cross-compilation for edge devices).
• Strong debugging and profiling skills across CPU and GPU, and a methodical approach to benchmarking and regression testing.
• Excellent collaboration and communication skills, with a track record of working closely with research or ML teams to move algorithms from prototype to production.

This role is based out of our Sterling Office and follows a hybrid schedule. We rely on in-person collaboration and ask that team members work onsite Tuesdays through Fridays, with the flexibility to work remotely on Mondays, unless there is an approved workplace accommodation. We believe that connection fuels innovation, and our in-office culture is designed to foster meaningful teamwork, mentorship, and shared success.
