Machine Learning Engineer (On-site)

On-site position in College Station, TX. US Persons. Multiple positions. $52k - $85k + Benefits

The Intelligent Systems Group at Lynntech is developing new technologies through Research and Development (R&D) to come up with solution to frontier challenges in Artificial Intelligence, Machine Learning (ML), and Data Science. We operate in a collaborative multi-disciplinary environment, where projects lie at the intersection of evolving technical fields, focusing on Intelligence, Surveillance, Reconnaissance (ISR) and Security, Navigation and Tracking, and Healthcare and Life Sciences.

Position Summary

The Intelligent System Group at Lynntech is a team of about 10 scientists, engineers, and programmers seeking to double its size over the next year. To that end, we are seeking full-time ML engineers to support existing projects while working alongside our scientists and other engineers. ML engineers are responsible for assembling data sets for testing models and methods, finding available models which are appropriate for the data processing needs of a specific project, setting up computational environments, and building and testing models. Due to the exploratory and interdisciplinary nature of our projects, duties associated with ML often overlap and intersect with those from other disciplines, such as data analytics and synthesis, as well as software and algorithm development. Thus, familiarity with disciplines outside of ML are valuable and domain expertise in other fields provides a novel context for application of ML methods.

For some of our more nascent projects, pre-existing data sets are not always available, so there is also a strong data acquisition (DAQ) and data synthesis aspect to our work. To that end, some projects involve working with hardware and sensors, most notably cameras. Projects may require operating DAQ systems and going out and collecting field or lab data. Other projects have virtual environments set up in which 3D models and simulations are used for creating training data using rendering engines, physics-based modeling software, and finite element analysis tools.

The Team

The Intelligent Systems Group at Lynntech is developing new technologies through Research and Development (R&D) to come up with solution to frontier challenges in Artificial Intelligence, Machine Learning (ML), and Data Science. We operate in a collaborative multi-disciplinary environment, where projects often lie at the intersection of different technical fields, broadly falling into one of the three industry domains:

  • Intelligence, Surveillance, Reconnaissance (ISR) and Security
  • Navigation and Tracking
  • Healthcare and Life Sciences

Within these domains we work to generate, plan, and execute highly innovative solutions in the fields of AI, state-of-the-art electro-optical/infrared, embedded navigation systems, human-machine interfaces, and other resources to solve real-world problems such as search and rescue, analysis of geospatial data to provide actionable intelligence, terrain monitoring, disaster recovery, computer vision for autonomous vehicles, assistive technologies for disabled users, data analytics, natural language processing, and mobile computing for Internet of Things (IoT) applications.

As part of our ongoing research efforts, we continuously evaluate topics from government-released R&D solicitations and write research proposals in response. Upon competitive selection for contract award, such proposals become active research projects. Our team has several such R&D projects running in parallel. Each project is coordinated by one of our Principal Investigators (PI) who are responsible for supervising and delegating workloads between projects and it is common for scientists, engineers, and analysists to be involved in two to three projects simultaneously.

A day in the life with the Intelligent Systems Group

Our projects lie at the interface between fundamental research and engineering, and we are often adapting ideas from disparate academic fields and finding ways to apply them in various real-world domains. We have several R&D projects running in parallel, and work focus shifts according to different project needs and deadlines. Each project is coordinated by one of our Principal Investigators (PI) who are responsible for supervising and delegating workloads between projects and it is common for scientists, engineers, and analysists to be involved in two to three projects simultaneously. You will start off working on individual tasks and filling in singular needs but over time be given responsibility for developing and maintaining larger pieces of projects and owning your own systems. We encourage our group members' growth and provide opportunities for taking on more responsibility, eventually leading projects and deciding the direction of future research.

Our projects leverage the following core disciplines:

  • Computer Vision, Image Processing, and Numerical Methods
  • Machine Learning and Natural Language Processing
  • Simulation, 3D Modeling, and Image Synthesis
  • Remote Sensing and Geospatial Analytics
  • State Estimation, Filtering, and Statistical Analysis
  • Data Acquisition, Synthesis, Wrangling, and Processing
  • Software Development and Sys Admin
  • Research, Proposal Writing, Grantsmanship, and Business Development

Even though you will start off focusing on one specific domain, team members are frequently involved on multiple projects with duties that span across these core disciplines. It is perfectly acceptable if find yourself slowly branching out or changing disciplines as your interests change and certain projects gain more traction than others. Branching out takes the form of joining existing projects or working on proposals to start new ones. Each of us is involved to some degree with the evaluation of government-released research solicitations. When batches of solicitations are released by various government entities, like NASA or the Department of Defense, for example, we come together as a team and decide on which ones we should pursue and who will lead efforts on writing proposals to the selected topics.

Interview Process

After applicants have submitted their application, our interviews follow a four-step process:

  1. Pre-screening and request for work sample. If an applicant's resume passes pre-screening, Lynntech will send out a candidate packet which contains information about the company and the team. We will also request a work sample which is demonstrative of the applicant's experience relevant to the job posting. If the work sample demonstrates relevant proficiency in the job domain, Lynntech will continue with scheduling a time for an interview.
  2. 1st Interview (Usually Phone/Virtual unless local candidate). [Duration: 1 hr] During this call, both parties will review background information and review eligibility requirements. Company policies, job expectations, work environment, and availability will be discussed. The interview may conclude here if the candidate is no longer interested in pursuing the opportunity or if the candidate does not meet basic eligibility requirements. We will also discuss the different roles in the group and establish the domain specific project needs which we have at that moment and candidate will be asked to rank their experience and comfort level with the various core disciplines. Candidates will be expected to elaborate on their relevant past project experience.
  3. Candidate Assessment, Part 1: If both parties choose to continue, candidates will be asked to complete and submit Part 1 of the Assessment which was included in their packets. This assessment covers fundamentals in computer literacy, programming, and mathematics. Lynntech will review the submission and before scheduling a second interview. Part 2 of the assessment is only requested if a second interview is scheduled.
  4. 2nd Interview (Usually On-site*) and Part 2 of Assessment. [Duration: 3 to 4 hr] If both parties choose to continue, an in-person interview will be scheduled, and the candidate is responsible for completing Part 2 of the assessment prior to the second interview. The candidate will be notified in advance if an optional domain specific assignment or live coding interview is required. This final step will be comprised of the following:
    1. Past Project Presentation/Demo: The candidate will give a 10-15 minute presentation/demonstration of a past personal or professional project which relates to one of our core disciplines. Your presentation should resemble more of a story than an academic talk and it can be an example from your past personal or professional experience. If you have physical or virtual demonstrations at hand, or something interactive, you're encouraged to bring them. It's also beneficial if you have pictures/graphics and videos walking us through your development process and showing the final result. Highlight any problems or challenges you faced along the way and how you overcame them. There will be time at the end for Q&A and open discussion. If you're uncertain about what topic to present on, please reference our technical domains for guidance. Duration: 25 to 45 min
    2. Project Domains and Core Disciplines Discussion: We will discuss what the existing project needs are and how the candidate's skill set can best fit the project needs. We will review the various roles, responsibilities, and how the various core disciplines relate to our projects. Duration: 30 to 40 min
    3. [Optional] Assessment Review: If reviewers have previously provided a domain specific assignment, candidate answers will be reviewed, and additional questions may be given. Interviewers will assess candidate's ability to reason through challenges and their ability to identify and test their assumptions when approaching problems. Duration: 30 to 60 min
    4. [Optional] Live Coding Interview: A live open-book set of coding problems. Candidates will be given programming problems which they must solve. Internet search will be available for looking up information and interviewers will be there to answer questions and help if necessary. This will test not only the candidate's ability to program, but also their ability to search for answers and ask for help and collaborate when appropriate. Duration: 30 to 60 min

* For long-distance candidates, this may be a virtual interview. If a job offer is made the candidate will be invited to for an on-site visit before a final response is expected.
