This role is responsible for delivering high-quality software solutions across EZCORP's digital product portfolio including customer-facing mobile and web applications, e-commerce platforms, internal store applications, and enterprise integrations with AI-assisted development at the core of how work gets done.This is a senior role that goes beyond individual contribution. The hands-on Senior Engineer is expected to lead and manage multiple concurrent projects i.e. owning technical direction, coordinating work across engineers and contractors, managing delivery timelines, and serving as the primary technical point of contact for their workstreams. AI is the force multiplier that makes this possible: the ideal candidate uses AI tools to operate at a scope and speed that traditionally required multiple engineers.This is not a traditional engineering role with AI tools bolted on. The ideal candidate treats AI as central to the entire development lifecycle i.e. from architecture and prototyping through code generation, testing, and documentation. They excel at architecting software systems optimally structured for AI-assisted code generation: modular, well-separated codebases with clear interfaces, comprehensive type definitions, and explicit contracts that enable AI tools to generate high-quality, production-ready code.This position requires strong full-stack expertise with frontend (React, Angular), backend (Node.js), cloud infrastructure (Azure, AWS), and database technologies, combined with hands-on experience integrating AI/ML capabilities into production systems and a deep understanding of how to structure code and workflows for AI collaboration.PROJECT & TECHNICAL LEADERSHIPLead and manage multiple concurrent projects simultaneously - owning technical direction, delivery timelines, and quality outcomes across parallel workstreamsBreak down complex initiatives into executable plans - features, milestones, dependencies, risks and drive them to completionCoordinate and direct the work of other engineers and contractors across distributed teams (US, LATAM, India), ensuring consistent standards and velocityServe as the primary technical point of contact for assigned projects - providing status, surfacing risks early, and communicating tradeoffs to engineering leadership and product stakeholdersConduct code reviews across projects, enforcing quality standards for both human-written and AI-generated codeMentor engineers on AI-assisted development practices, architectural patterns, and delivery disciplineBalance hands-on execution with delegation - knowing when to build, when to direct, and when to unblock othersESSENTIAL DUTIES & RESPONSIBILITIESDesign, build, and maintain full-stack applications using React, Angular, and Node.js across EZCORP's digital product portfolioSolve complex problems related to scalability, reliability, performance, and reusabilityWork with Product Managers, UX Designers, and engineers to understand and refine features using agile methodologiesEstablish industry-standard QA automation - leveraging AI to generate test plans, unit tests, and automation suites in parallel with developmentSupport the build and management of backend infrastructure including integrations with third-party vendors and internal platform servicesContribute to a maintainable, high-quality, performant codebase structured for both human maintainability and AI-assisted extensibilityExplore, assess, and prototype new technologies to drive innovation and problem solvingActively engage in product and technical discussions for feasibility and adherence to overall roadmaps and architectural strategyAI ENGINEERING & AI-ASSISTED DEVELOPMENTLeverage AI coding tools (Claude Code, GitHub Copilot) as primary accelerators for development, code review, and refactoringPrototype and validate solutions rapidly using AI-assisted development compressing proof-of-concept cycles from weeks to daysDesign and integrate AI/ML capabilities into platform services, including:LLM integration (Azure OpenAI, Gemini, Claude) for intelligent features and automationComputer vision workflows (e.g., product identification, document scanning)Vector search and RAG pipelines (Azure AI Search, pgvector) for semantic search and data matchingIntelligent data processing and workflow automationBuild and maintain agentic workflows and AI-augmented pipelines that operate within defined governance and human-in-the-loop controlsFollow and contribute to EZCORP's AI governance standards - code generation guardrails, review requirements, and documentation practicesEnsure quality and security of AI-generated code through rigorous review - AI accelerates, humans validateStay current on emerging AI tools, models, and practices;
