ABOUT THIS ROLE

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.

ROLE RESPONSIBILITIES

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 WebSocket 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, DevOps, and architecture teams to accelerate CI/CD pipelines, enhance stack-wide type safety, and deprecate legacy systems without disrupting product delivery.

OUR IDEAL CANDIDATE

5+ Years of Professional Development Experience: A proven track record building enterprise-grade applications, with a heavy emphasis on full-stack TypeScript 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 WebSockets.
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.

COMPENSATION

The beginning annual salary range for this role is $159,000 - $192,000 USD and is determined by location, job-related experience, and education/training. Your total earning potential is amplified by a bonus structure tied to meeting goals, and you will become an owner from day one through our employee equity program.
