Senior AI Software Engineer Visa Sponsorship Jobs in New Jersey

Summary:

We are seeking an exceptional Full-Stack AI Software Engineer to design, build, deploy, secure, and continuously improve enterprise software and AI-enabled applications. This is a hands-on engineering role for a highly capable product engineer who can translate complex business problems into secure, scalable, and intuitive technical solutions. The engineer will work directly with business stakeholders in an interactive, iterative development model—rapidly converting ideas into working prototypes, testing solutions with users in real time, and refining functionality until the intended business outcome is achieved. The successful candidate will combine strong traditional software-engineering fundamentals with practical experience using modern AI-assisted development tools, large language models, AI agents, and automation frameworks. The engineer will own applications throughout their lifecycle, including architecture, development, testing, deployment, monitoring, vulnerability remediation, maintenance, modernization, and retirement. Each engineer may be responsible for the health, delivery, and continued evolution of up to three applications at any given time.

Essential Job Duties and Responsibilities:

Product and Solution Engineering

• Partner directly with business stakeholders to understand operating processes, identify root problems, define measurable outcomes, and engineer effective technical solutions.
• Translate ambiguous business needs into clear functional requirements, technical designs, user stories, acceptance criteria, and production-ready software.
• Work interactively with users through rapid prototyping, demonstrations, feedback sessions, and iterative releases.
• Build new applications and enhance existing platforms across the frontend, backend, application programming interface, integration, data, and infrastructure layers.
• Develop intuitive, accessible, responsive, and high-performing user experiences.
• Design reusable services, components, APIs, workflows, and integration patterns.
• Make thoughtful build-versus-buy and configuration-versus-custom-development recommendations.
• Balance delivery speed with security, reliability, maintainability, scalability, and long-term architectural integrity.

AI-Native Engineering

• Use modern AI engineering tools throughout the software development lifecycle to improve development speed, quality, testing, documentation, and maintainability.
• Design and implement AI-enabled capabilities using large language models, retrieval-augmented generation, embeddings, vector search, structured outputs, tool calling, multimodal models, and agentic workflows.
• Build AI agents that can securely interact with applications, APIs, databases, documents, and enterprise systems.
• Develop effective prompts, system instructions, context-management strategies, tool definitions, workflows, and reusable AI skills.
• Evaluate and select appropriate models based on accuracy, latency, security, cost, reliability, and business requirements.
• Implement model evaluations, regression tests, guardrails, human-review controls, grounding, observability, and fallback mechanisms.
• Identify and mitigate hallucination, prompt-injection, data-leakage, model-bias, unsafe-output, and unauthorized-tool-use risks.
• Measure AI solutions using defined quality, accuracy, safety, performance, adoption, and business-value metrics.
• Maintain awareness of rapidly evolving AI models, development tools, frameworks, security risks, and engineering practices.

Software Delivery and Testing

• Own software delivery from initial discovery and architecture through development, testing, deployment, production support, and continuous improvement.
• Write clean, modular, testable, secure, and well-documented production code.
• Develop and maintain unit, integration, API, user-interface, regression, performance, security, and end-to-end automated tests.
• Use AI-assisted testing and automation tools while independently validating generated code and test results.
• Participate in peer reviews, design reviews, architecture reviews, threat modeling, and release-readiness assessments.
• Build and maintain continuous integration and continuous delivery pipelines.
• Release software through safe, incremental, observable, and reversible deployment practices.
• Ensure that functional requirements and acceptance criteria are demonstrably satisfied before production release.

Application Ownership and Operational Excellence

• Serve as the accountable engineer or technical owner for up to three assigned applications.
• Maintain a clear understanding of each application’s architecture, business purpose, users, integrations, data flows, dependencies, risks, and operational requirements.
• Monitor application availability, performance, capacity, security, errors, and user experience.
• Diagnose and resolve production incidents, defects, integration failures, and performance issues.
• Perform routine maintenance, framework and dependency upgrades, operating-system or platform updates, certificate renewals, configuration changes, and technical-debt remediation.
• Patch application and infrastructure vulnerabilities within established remediation timelines.
• Maintain current application documentation, support procedures, runbooks, architecture diagrams, data-flow diagrams, deployment instructions, and recovery procedures.
• Participate in incident response, root-cause analysis, corrective-action planning, disaster-recovery testing, and business-continuity exercises.
• Recommend modernization, re-platforming, consolidation, or retirement when an application no longer meets business or technical standards.

Security, Architecture, Data, and Support Collaboration

• Work closely with the Information Security team to implement secure coding standards, identity and access controls, encryption, secrets management, vulnerability management, logging, monitoring, and regulatory controls.
• Partner with Enterprise Architecture to ensure solutions align with approved technology standards, integration patterns, cloud strategies, and target-state architecture.
• Collaborate with enterprise database and data-management teams on data models, storage patterns, data quality, lineage, retention, privacy, and performance.
• Coordinate with IT Support and operations teams to ensure applications can be effectively monitored, supported, maintained, and recovered.
• Work with infrastructure, cloud, network, identity, DevOps, quality-assurance, product, legal, risk, and compliance teams as required.
• Clearly communicate technical decisions, constraints, risks, tradeoffs, progress, and recommendations to both technical and nontechnical audiences.

Engineering Standards and Governance

• Follow established software-development lifecycle, change-management, security, architecture, data-governance, and release-management standards.
• Ensure applications comply with applicable legal, regulatory, privacy, records-management, accessibility, and industry requirements.
• Maintain traceability between business requirements, technical designs, code changes, tests, approvals, and releases.
• Protect confidential, proprietary, customer, and regulated data throughout the development and production lifecycle.
• Ensure AI-generated code and content are reviewed, tested, licensed appropriately, and treated with the same rigor as human-created work.
• Contribute reusable engineering patterns, libraries, templates, prompts, skills, development standards, and lessons learned to the broader engineering organization.
• Mentor other engineers and help raise the organization’s standards for AI-enabled software delivery.
