ARiA is an Equal Opportunity Employer.

Position Description:

ARiA is looking for highly motivated self-starters and low-ego team players to join our team as Senior Software Engineers.

These positions are an opportunity to join a rapidly growing firm where you will engage deeply in challenging problems while developing cutting-edge technologies that address crucial needs.

Strong candidates for these roles at ARiA must value excellence and work with confidence, but without ego. Our engineers and scientists all have deep knowledge and exercise a high degree of leadership in their daily work. Members of the ARiA team have strongly-held, defensible ideas and advocate for what they believe is right, but are quick to exercise intellectual humility and acknowledge that they can often be wrong. Successful employees of ARiA are adept at working closely and collaboratively with team members and identifying and evaluating trade-offs when developing solutions.

As a Senior Software Engineer you will perform a variety of software engineering tasks working in close coordination with other ARiA scientists and engineers including design, development, and testing of:

  • numerical-simulation software,
  • scientific-visualization software,
  • machine-learning software, and
  • signal-processing software

to support prototypes and products such as training tools integrated with real-time physics-based simulation and AI tools integrated with tactical systems.

Responsible for:

Algorithm and software design, development, research, and testing to support prototypes and products

Supporting the transition of research algorithms to fielded systems

Preparing documentation to summarize design and status of prototypes and products

Assisting with in-field integration, testing, and support, with some local travel required

Sample tasks:

Developing an interface between a C++ underwater-acoustics physics engine and a video game for education and training

Developing a JavaScript backend for a scenario-design and management tool for players and integration of that system with a learning-management system (LMS)

Developing algorithms and software for a cloud-deployed cognitive tool that allows natural-language query of legal documents to answer user questions about government regulations and supporting the DevOps process for deployment of the prototype


Applicants selected for employment will be subject to a government security investigation and must meet eligibility requirements, including U.S. citizenship, for access to sensitive information.

Bachelor’s degree or greater in a relevant technical field (Computer Science, Engineering, or equivalent)

Expertise designing and developing code using modern programming/scripting languages such as C, C++, Golang, JavaScript (and variants), and Python

Expertise developing and deploying software in an agile, continuous-integration (CI) framework across a variety of hardware platforms (desktop, server, cloud) using modern tools including containerization (e.g., Docker, Kubernetes)

Exceptional ability and desire to acquire new knowledge and skills to solve challenges

Ability to work independently but collaboratively

Ability to manage multiple projects in a fast-paced professional office environment

Ability to communicate technical solutions to colleagues and customers

Superior oral and written communications skills

Desirable Skills, Qualifications, and Experience:

Master’s degree or greater in a relevant technical field (Acoustics, Electrical Engineering, Computer Science, or similar) or equivalent professional experience

Master’s degree or greater in a relevant technical field (Computer Science, Engineering, or equivalent) or equivalent professional experience

Knowledge of and experience with GPGPU programing (CUDA, TensorFlow)

Knowledge of and experience with deep learning and modern deep-learning frameworks (TensorFlow, PyTorch)

Knowledge of and experience with image processing including modern deep-learning methods

Knowledge of and experience with natural-language-processing and/or information retrieval

Experience with scientific computing (e.g., numerical integration, special functions)

Knowledge of and prior practical work in signal processing (e.g., linear-system theory, digital signal processing)

Exposure to signa- processing applications in radar or sonar such as: beamforming, matched filtering, and spectral estimation

Knowledge of and facility with concepts from college-level physics (e.g., acoustics, wave propagation)

Knowledge of and facility with concepts from college-level mathematics (e.g., partial differential equations and linear algebra)
