Senior Fullstack Software Engineer

LVT is redefining how businesses operate in the physical world, moving beyond traditional security solutions to deliver AI-driven, actionable intelligence that makes sites smarter, safer, and more secure. Since pioneering our first mobile, solar-powered units, our commitment to scrappy, hands‑on innovation has made us an established leader and one of the fastest‑growing companies in intelligent site technology. We are building the next generation of solutions—from our physical units in the field to a powerful Agentic AI platform—that allows our customers to gain unprecedented visibility and control over safety, compliance, and operations.

As a Senior Fullstack Software Engineer at LVT, you will play a critical role in designing, building, and scaling software across our entire user interface surface area and the mission‑critical backend services supporting it. You will own features end‑to‑end—from building responsive React applications to optimizing our federated GraphQL subgraphs. Working alongside a highly collaborative team, your engineering judgment will directly shape how enterprise customers interact with real‑time IoT data and advanced automated workflows.

• Deliver High‑Quality Software End‑to‑End: Design, build, test, and ship robust features across our full stack, ensuring code aligns with high‑performance standards from UI components to backend REST and GraphQL services.
• Cross‑Service Architecture & Debugging: Trace, isolate, and resolve complex, systemic bugs across service boundaries (UI, API gateways, subgraphs, and legacy codebases) to ensure seamless performance.
• API & Data Integrity: Define clear data contracts between microservices, maintain schema federation hygiene, and architect secure, scalable real‑time Web Socket data flows.
• Promote Reliability and Performance: Write and run comprehensive tests, instrument critical system metrics, and build operational dashboards to proactively monitor system health and minimize downtime.
• Technical Mentorship: Provide technical guidance and constructive code reviews to mid‑level and junior engineers, encouraging best practices and continuous learning across the team.
• Continuous Engineering Improvement: Collaborate across adjacent QA, Dev Ops, and architecture teams to accelerate CI/CD pipelines, enhance stack‑wide type safety, and deprecate legacy systems without disrupting product delivery.

• 5+ Years of Professional Development
  
  Experience:
  
  A proven track record building enterprise‑grade applications, with a heavy emphasis on full‑stack Type Script architectures.
• Frontend & Framework Mastery: Deep production experience working with React and modern Next.js environments (including App Router and server actions).
• Backend & API Expertise: Strong command of Node.js (NestJS preferred) and hands‑on experience designing schemas, resolvers, and subscriptions using Apollo Server or similar GraphQL ecosystems.
• Data & Real‑Time Systems Knowledge: Proficiency with relational databases (MySQL preferred), query builders/ORMs (like Knex), and experience scaling real‑time web applications using Web Sockets.
• Security & Infrastructure Fundamentals: Solid understanding of modern authentication/authorization patterns (OAuth/OIDC, JWT) alongside familiarity with Docker, containerization, and modern CI/CD practices.
• Problem Solver & Systems Thinker: Exceptional analytical skills with the ability to dive into unfamiliar or legacy codebases, deduce business logic, and refactor effectively.
• Compelling Communicator: Strong interpersonal and collaboration skills, with an innate ability to lead cross‑team design discussions and articulate technical strategies clearly to stakeholders.
