The Role
Senior Full Stack Engineer responsible for building and operating secure, scalable web products and integrations using Next.js, React, TypeScript, C#, .NET, and Azure. The role owns end-to-end features, contributes to architecture, ensures production readiness, and supports regulated workflows. Responsibilities also include integrating AI capabilities such as LLMs, prompt engineering, RAG, and AI coding agents; applying secure development practices; mentoring engineers; and collaborating with product and client-facing teams.
Summary Generated by Built In
Hiring a Senior Full Stack Engineer to design, build, and
operate secure, scalable products and integrations across our global mobility
platform. You will deliver hands-on engineering across Next.js and React front
ends and C# and .NET services running on Microsoft Azure, operating in a
regulated, global environment. This role is for an experienced engineer who can
own end-to-end features, contribute to architectural decisions, and
consistently deliver production-ready solutions using agentic development practices
including spec-driven development and agent-driven development with tools such
as Claude Code and Codex. You will build AI-native products and workflows,
integrating AI capabilities directly into the applications and services you
deliver
•Build and evolve modern web experiences using Next.js,
React, and TypeScript with a focus on performance, reliability, and usability.
•Design and implement backend services and APIs using C#, .NET, and WebAPI,
including integrations that support payroll, tax, and immigration workflows.
•Deliver Azure-native implementations using Microsoft PaaS services, secure
patterns, and operational best practices.
•Contribute to system architecture and technical design, including integration
patterns using REST and event-driven approaches.
•Own production readiness for your work including logging, monitoring and
alerting, incident response support, and operational documentation.
•Apply secure development practices appropriate for regulated environments
including privacy, auditability, and data protection.
•Partner with product, implementation, and client-facing teams to translate
requirements into technical plans and deliverables.
•Use agentic development practices including agent-driven development with
Claude Code, Codex, or similar AI coding agents to accelerate design,
implementation, testing, and operations across the SDLC.
•Work in a spec-driven development workflow, authoring detailed specifications
that guide both human and AI agent implementation, translating clear
requirements into predictable delivery and maintainable code.
•Design and implement AI-powered features within products including prompt
engineering, LLM integration, retrieval-augmented generation (RAG) patterns,
and AI-assisted user workflows.
•Evaluate, integrate, and operationalize AI APIs, models, and toolchains within
application architectures, ensuring responsible AI usage, cost management, and
observability.
•Mentor and support other engineers through code reviews, pairing, and
technical guidance.
Required Qualifications
•5+ years professional software development experience building enterprise web
applications and services.
•Strong experience designing and building large JavaScript applications with
Next.js and or React (TypeScript, state management, performance optimization).
•Strong backend development experience in C# and .NET (ASP.NET, WebAPI, MVC)
including API design and service patterns.
•Proven experience with Microsoft Azure designing and building cloud solutions
using PaaS services, frameworks, and operational tooling.
•Experience delivering systems in regulated or compliance-oriented environments
(security controls, auditability, privacy, data handling).
•Strong engineering fundamentals including design patterns, separation of
concerns, scalable architecture, and pragmatic trade-offs.
•Experience with agentic or AI-assisted development workflows such as
spec-driven development, agent-driven development using tools like Claude Code
or Codex, or similar AI coding agent practices.
•Demonstrated ability to build products that incorporate AI capabilities
including prompt design, LLM API integration, or AI-augmented user experiences.
Preferred Qualifications
•Azure certifications and/or Microsoft certifications.
•Experience with event-based and distributed systems including messaging and
asynchronous workflows.
•Data and persistence experience with SQL Server and ORMs (Entity Framework,
Hibernate) plus caching strategies.
•Strong testing discipline including TDD and BDD, xUnit, Jest or Mocha, CI/CD
automation, and quality gates.
•Experience building analytics and reporting with BI and data visualization
tools and domain-specific reporting.
•Exposure to mobile ecosystems (iOS and Android) and API design supporting
mobile clients.
•Experience with prompt engineering patterns, RAG architectures, vector
databases, or AI orchestration frameworks (e.g., LangChain, Semantic Kernel,
Azure AI Services).
•Familiarity with AI code generation and review workflows, including evaluating
and curating AI-generated code for production readiness.
•Experience contributing to or building AI-augmented internal tools, developer
experience tooling, or intelligent automation within engineering workflows.
Technical Skills We Value
•Frontend: Next.js, React, TypeScript, HTML, CSS, SPA architecture, performance
and accessibility
•Backend: C#, ASP.NET, WebAPI, RESTful design, authentication and authorization
patterns
•Cloud: Azure PaaS services, observability, secure networking, identity,
deployment automation
•Engineering practices: Git-based workflows, secure SDLC, spec-driven
development, AI-assisted code reviews, automated testing, documentation
•AI-enabled delivery: agentic development using Claude Code, Codex, or similar
AI coding agents; spec-driven development workflows; prompt engineering; LLM
API integration; RAG patterns; AI orchestration frameworks; responsible AI
practices and observability
What Success Looks Like
•Delivers complex features end-to-end with high quality, predictable timelines,
and production readiness.
•Produces clean, maintainable code—whether hand-written or AI-generated—with
strong test coverage and clear documentation.
•Identifies and resolves performance, reliability, and security issues before
they reach production.
•Contributes meaningfully to architecture and raises standards through code
reviews and technical leadership.
•Communicates clearly, flags risks early, and collaborates effectively across
teams.
•Effectively leverages agentic development tools and AI-augmented workflows to
increase velocity while maintaining quality and security standards.
Education
•Bachelor’s degree in Computer Science, Engineering, or related field required.
•Master’s degree preferred.
