Credence has an immediate opening for a Senior Applications Engineer who will be primarily responsible for supporting the Defense Logistics Agency, Defense Automated Addressing Systems (DAAS), AI/ML program.The Senior Applications Engineer analyzes and studies complex system requirements and leads the design and implementation of software tools and subsystems that support software reuse and domain analyses. This is a hands-on role that pairs deep applications engineering with front-end UI/UX development: you will be handed real enterprise applications with real user friction, and part of your mandate is to diagnose why users aren't engaging and rebuild experiences - interfaces, dashboards, and data visualizations surfacing AI/ML outputs - that they actually want to use. You will manage software development and support efforts using formal specifications, data flow diagrams, and other accepted design techniques and Computer-Aided Software Engineering (CASE) tools, while providing reliable cost and schedule estimates to program leadership. To succeed in this role, you should combine deep hands-on engineering expertise with modern front-end skills, the ability to guide development teams, improve existing systems, and enforce disciplined configuration management practices in support of DAAS AI/ML modernization efforts.Responsibilities include, but are not limited to the duties listed below:Analyzing and studying complex system requirements to inform software design and implementation decisionsDesigning software tools and subsystems to support software reuse and domain analyses, and managing their implementationManaging software development and support using formal specifications, data flow diagrams, other accepted design techniques, and Computer-Aided Software Engineering (CASE) toolsEstimating software development costs and schedule, and communicating estimates and risks to program and project leadershipReviewing existing programs and assisting in making refinements, reducing operating time, and improving current techniquesSupervising software configuration management, including version control, change control, and release integrity across the development lifecycleDeveloping machine learning models in support of various use cases, including:Transaction AnomaliesInventory ReconciliationSupply Chain DecisionsAudit ReadinessContent IntelligenceAIOpsFraud & Threat DetectionEntity ResolutionRecommendation EnginesGenerative AIArchitecting and building performant, responsive, accessible (WCAG 2.1 AA) user interfaces using React/Next.js with TypeScript, HTML5, and CSS3Auditing existing applications to identify user adoption barriers through heuristic analysis, user research, and behavioral data, and translating insights into measurable improvements in engagement and task completionDesigning and building interactive dashboards and data visualization layers (D3.js, Chart.js, or similar) that surface AI/ML outputs, analytics, and operational metrics to end usersDeveloping reusable component libraries and design systems that scale across multiple productsLeveraging AI coding assistants (e.g., GitHub Copilot, Cursor) as a productivity multiplier within disciplined, secure development workflowsContributing to code reviews, CI/CD pipelines (Jenkins, Git), artifact and dependency governance (Sonatype Nexus), and agile ceremonies (JIRA)Collaborating with cross-functional teams, developers, analysts, and stakeholders to deliver software solutions that meet or exceed client expectationsDocumenting and communicating the results of your effortsRelated duties or special projects as assignedRequirementsUS citizen with the ability to obtain a security clearance is requiredBA/BS in a technical discipline from an accredited universityAt least ten (10) years of applicable experience in applications engineering, software development, or a related disciplineDemonstrated experience analyzing complex system requirements and designing software tools and subsystemsExperience managing software development efforts using formal specifications, data flow diagrams, and other accepted design techniques and CASE toolsDemonstrated ability to estimate software development costs and schedulesExperience with software configuration management tools, systems, and processesDemonstrated experience developing and deploying machine learning models in operational or production environmentsExperience engineering AI-driven anomaly detection models (e.g., time-series forecasting approaches such as Prophet) to monitor API traffic or system telemetry5+ years of hands-on experience in UI/UX design and front-end development, with a portfolio demonstrating measurable impact on user experienceProven track record of improving adoption or usability on complex enterprise or government applications -
