Basis Technology is dedicated to engineering a safer and more productive world by building proven AI solutions for analyzing text, connecting data silos, and uncovering digital evidence. From making governments smarter to national security to fighting financial fraud, we make sense of messy, voluminous data by applying our AI, machine learning, and cyber forensics to power the most important systems on earth. It’s challenging work, but we love it. Because we’re wholehearted believers in the power of persistence to solve any problem, and we solve problems that matter. 

If you’ve got ingenuity, ambition, and heart, and you want to come to a company where you can make a difference, then you’ll feel right at home among our diverse team of creators. From engineers to graphic designers, we empower every person in our company to make their mark. So don’t come here for a desk job. Show up ready to build.

Job Overview:

As a Performance Software Architect, you will analyze existing performance and lead improvement strategy, including architectural product changes, to increase speed and reduce memory usage of components of Basis’ Rosette platform.  This role will require a strong theoretical background in computer science fundamentals, including data structures and algorithmic complexity (Big-O analysis). Equally, the candidate must be able to apply these theoretical principles for intensely practical tasks, where a few-percentage-point improvement in performance may translate to a big impact in a product’s reception in the market.  The range of performance-critical factors is large so candidates should have the ability to research the performance literature to understand and analyze new domains.

Job Responsibilities:

  • Analyze performance of software with profiling and data-flow tracing tools, through all stages of disk, memory, CPU caches, FPU, and GPU or TPU operations
  • Identify bottlenecks at each of these stages and propose improvements, both as series of small increments, and through fundamental algorithmic and architectural advances
  • Understand key performance structures and algorithms, such as hash and B-tree data structures, Bloom filters, and linear algebraic processing
  • Investigate high-dimensional indexing approaches such as Locality Sensitive Hashing for Approximate Nearest Neighbor queries
  • Investigate and apply object-size optimization to fit caches
  • Apply linear algebra library optimizations including loop unrolling and quantization
  • Analyze output from hardware-level analytic tools such as NVIDIA Nsight, determining optimizations to fully load FPU and GPU
  • Analyze runtime data structures, thread dumps, flame graphs, and garbage creation/collection histories, to quantify and improve drivers of both initial and sustained throughput
  • Create test harnesses for code performance analysis and automated regression testing
  • Be responsible and accountable for performance specification and optimization across the software lifecycle, from R&D and initial design, through maintenance
  • Be a mentor and role model for design reviews, code, and test cases
  • Participate in agile sprint and release planning

Job Requirements:

  • 5+ years experience in modern programming languages
  • Broad familiarity with computer language theory as applied across Java, C++, Python, deep learning frameworks such as TensorFlow, PyTorch, and Deeplearning4j, and data/retrieval systems such as Lucene and MongoDB
  • Be able to apply linear algebra, probability and statistics, and calculus to machine learning techniques as diverse as Hidden Markov Models and Convolutional Neural Networks
  • Familiarity with deep learning frameworks such as TensorFlow, PyTorch, and Deeplearning4j is a plus
  • Able to quickly adopt new languages, tools, and techniques by reading manuals and searching and reading scholarly literature
  • Experience using profiling and other performance tools
  • Experience working with a team to deliver software
  • Master’s degree in Computer Science, or equivalent self-study and experience
  • A passion to design, build, and improve software applications

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.

We are also committed to the full inclusion of all qualified individuals. As part of this commitment, we will ensure that persons with disabilities are provided with reasonable accommodations. If reasonable accommodation is needed to participate in the job application or interview process, to perform essential job functions, and/or to receive other benefits and privileges of employment, please contact

Voluntary Self-Identification

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

As set forth in Basis Technology’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Why are you being asked to complete this form?

We are a federal contractor or subcontractor required by law to provide equal employment opportunity to qualified people with disabilities. We are also required to measure our progress toward having at least 7% of our workforce be individuals with disabilities. To do this, we must ask applicants and employees if they have a disability or have ever had a disability. Because a person may become disabled at any time, we ask all of our employees to update their information at least every five years.

Identifying yourself as an individual with a disability is voluntary, and we hope that you will choose to do so. Your answer will be maintained confidentially and not be seen by selecting officials or anyone else involved in making personnel decisions. Completing the form will not negatively impact you in any way, regardless of whether you have self-identified in the past. For more information about this form or the equal employment obligations of federal contractors under Section 503 of the Rehabilitation Act, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at
