Software Engineer, Senior at GRVTY

<p><strong>What Impact You'll Have</strong></p> <p>GRVTY is looking for a Senior Software Engineer to join a small, technically focused team supporting national security missions at a customer site in Dayton, Ohio. This is hands-on engineering work — you will be designing and building Python-based software tools that support optical signature modeling, spectral data analysis, and machine learning-enabled sensor workflows. The work spans algorithm development, data pipeline construction, and integration of ML capabilities into operational and analytical environments.</p> <p>You will work directly with scientists, sensor domain experts, and intelligence analysts — translating complex technical requirements into functional, maintainable software. This is not a role for someone looking to coast. We want someone who is technically sharp, can operate with a degree of autonomy, and understands that the software they build has real downstream impact on mission outcomes.</p> <p><strong>What You'll be Owning</strong></p> <ul> <li>Design, develop, and maintain Python-based software tools supporting optical signature modeling, spectral sensor data processing, and analytical workflows.</li> <li>Work with sensor physicists, data scientists, and machine learning engineers to translate technical concepts and mission requirements into working software.</li> <li>Build and optimize data pipelines for ingesting, processing, and analyzing large-scale scientific and sensor datasets.</li> <li>Develop and integrate machine learning workflows — including training data preparation, model integration, and evaluation — into operational toolsets.</li> <li>Create clear software architecture documentation, workflow diagrams, and code structure so tools can be maintained, extended, and transitioned effectively.</li> <li>Test, validate, and troubleshoot algorithms and software modules across development and deployment environments, including classified workspaces.</li> <li>Manage and maintain Git repositories with discipline — clean commits, meaningful documentation, and reproducible builds.</li> <li>Contribute to a culture of technical rigor: peer reviews, coding standards, and honest engagement with complex problems.</li> </ul> <p><strong>What You Must Have</strong></p> <ul> <li><span data-teams="true">Active Top Secret clearance with ability to obtain SCI and CI polygraph.</span></li> <li>Bachelor's degree in Computer Science, Engineering, Physics, Mathematics, Data Science, or a related STEM field. Equivalent hands-on experience will be considered. <ul> <li>9+ years of professional software development experience, with demonstrated focus on scientific computing, algorithm development, data processing, or related technical domains or 7+ years of experience and a Masters degree</li> </ul> </li> <li>Expert-level Python programming, including object-oriented design, modular architecture, and production-quality code.</li> <li>Experience developing software for data-intensive workflows — sensor data, scientific data, simulation, or equivalent.</li> <li>Ability to work from technical or scientific requirements and produce well-structured software architecture, logic flows, and implementation plans.</li> <li>Comfortable operating in both Windows and Linux environments, including secure or classified customer workspaces.</li> <li>Familiarity with source control and development tooling: Git, GitLab, Bitbucket, Jira, Jenkins, or equivalent.</li> <li>Strong communication skills — able to work directly with domain experts who are not software engineers and translate what they need into software that actually works.</li> </ul> <p><strong>What Would be Nice to Have</strong></p> <ul> <li>Experience with optical signature modeling, EO/IR sensor data, spectral analysis, or hyperspectral data processing.</li> <li>Familiarity with machine learning frameworks and workflows: PyTorch, TensorFlow, scikit-learn, or equivalent.</li> <li>Experience with scientific Python libraries: NumPy, pandas, OpenCV, SciPy, or similar.</li> <li>Background in signal processing, image processing, or remote sensing data workflows.</li> <li>Experience with simulation, modeling, or mission analysis software in a defense or intelligence context.</li> <li>Familiarity with ML/Ops practices — training pipelines, data labeling, model evaluation, and deployment workflows.</li> <li>Experience integrating algorithms into existing operational software suites.</li> <li>Proficiency in a secondary technical language: C, C++, MATLAB, Java, or Rust.</li> <li>Advanced degree in a relevant technical field (Computer Science, Electrical Engineering, Physics, Image Science, or related).</li> <li>Prior experience supporting defense, intelligence, or classified customer environments.</li> <li>Experience with CI/CD practices, automated testing, and DevSecOps tooling.</li> </ul><div class="content-conclusion"><p id="isPasted"><strong>Why Choose GRVTY</strong></p> <hr> <p>The toughest national security challenges demand vision and ingenuity, not just resources.
