Senior Deep Learning / Computer Vision Engineer


Senior Network Engineer



Tewksbury, Massachusetts, United States


Job Description:

We are seeking a motivated and talented algorithm scientist to join a machine learning algorithm development team and participate with hands-on contributions to advanced real-time detection and computer vision algorithms, and supporting software infrastructure. You will be involved in the development of computer vision, image processing, and deep learning algorithms for our real-time airport personnel and baggage scanning products. You will be working on algorithms for multi-view 2-d and 3-d volumetric detection of prohibited items concealed on passengers or in their baggage. We have thousands of scanners in daily operation around the world on which your algorithms will be deployed.

While this position will have the opportunity to telework much of the time, local candidates are strongly preferred.

Primary Responsibilities

  • Contribute to a team that is developing object detection and image processing system architectures that will be implemented in real-time decision processes in security screening systems fielded across the world
  • Hands on research and development of advanced deep learning, object detection, image processing, and scene segmentation algorithms.
  • Utilize real-time coding methods, architectures and languages to implement advanced algorithms as highly optimized production quality code
  • Design and implement new algorithms and improve existing algorithms in C++ and Python class structure using good software engineering techniques with emphasis on reusability and efficiency.
  • Train machine learning classifiers with emphasis on classifier generalization
  • Analyze data, make recommendations, write technical reports
  • Interface with other software teams to integrate algorithms with external software components.
  • May require occasional travel (5%), domestic or international, to assist with data collections

Basic Qualifications

  • BS/MS in computer science/engineering in a related subject such as data science, computer vision, machine learning or AI.
  • 8 years industry and/or research experience developing algorithms in one or more of the following areas: image/radar/video processing, computer vision, machine learning, or deep learning.
  • Expert in PyTorch with at least 3 years experience in development for computer vision
  • Experience designing machine learning algorithms, including creating software for data loading, training, and inference for novel machine learning architectures
  • 3 years experience in image processing techniques (filtering, segmentation, edge detection, object detection)
  • Experience profiling and optimizing real-time algorithm runtime
  • Algorithm prototyping and performance evaluation in Python
  • Strong math, analytical and communication skills
  • Must have positive, team focused attitude and approach to work tasks.
  • Ability to obtain and maintain a US secret security clearance, which requires US Citizenship. We are unable to sponsor visas for this position and require applicants to be either a US citizen or a permanent resident (Green Card holder)

Preferred Qualifications

  • PhD in computer science/engineering in a related subject such as computer vision, machine learning or AI
  • 3 years experience developing deep learning computer vision algorithms using CNNs, GANs, Transformers, Single and Two-stage detectors.
  • 5 years machine learning classifier development experience including approaches to use limited data to train and validate generalizable classifiers
  • Strong understanding of supervised, semi-supervised and self-supervised machine learning
  • 2 years C++ development in a scientific software development environment
  • Familiarity with image reconstruction algorithms
  • Experience with Windows and Linux development environments including writing Perl and shell scripts
  • Familiarity with Azure and Git
  • Basic knowledge of the electromagnetic spectrum (x-ray/radar) and related technologies.
  • Current US secret security clearance
