Next.js Developers working on large-scale applications often encounter challenges related to performance optimization, such as ensuring efficient server-side rendering and managing code splitting for faster load times. They may also need to address complex routing scenarios and handle data fetching from multiple APIs without slowing down the user experience. Collaboration with UI/UX designers and backend teams is essential to integrate features smoothly, and staying updated with the latest Next.js features is important to maintain scalability and security.

What is the difference between Next Js Developer vs React Developer?

Work EnvironmentWeb development teams, often with full-stack responsibilitiesFront-end development teams, UI/UX focus
Industry UsageWeb applications requiring SEO and performance optimizationInteractive web interfaces and single-page applications

The choice depends on project requirements for SEO, performance, and rendering strategies.

Their responsibilities often include developing user interfaces, optimizing performance, and ensuring web applications are SEO-friendly. Next.js developers also work with backend APIs, manage deployments, and integrate modern web technologies to deliver robust and scalable applications.

Is NextJS fullstack or frontend?

Next.js is a React framework primarily used for building frontend applications, but it also supports backend development with server-side rendering and API routes, making it a fullstack framework. Next.js developers often work with both client-side and server-side code to create dynamic web applications.

What is the salary of NextJS developer?

Familiarity with tools like Git, RESTful APIs, and experience using frameworks such as Node.js or TypeScript is highly beneficial. Excellent problem-solving abilities, collaboration, and effective communication skills help developers work efficiently within teams and deliver high-quality solutions. These skills ensure optimized, scalable, and maintainable applications that meet client and business needs in a fast-evolving tech landscape.

Job description

Senior Full Stack Engineer (React / Next.js)
At some point in the future, every business will answer their phone with voice AI. We are making sure that when they build that AI agent, the experience of doing so doesn't suck.
We're growing incredibly fast and need someone who thrives in a dynamic, high-pressure environment to work across our engineering stack. This role is critical to the success of our company. We're looking for someone who will roll up their sleeves, dig in, and double down when things get tough.
We want someone highly technical, driven, and fun to work with. You'll be working directly with engineering, product, and customer-facing teams to build and ship fast.
NOTE: This is an engineering position. You will be writing a lot of code, and it will be a lot of work. If you're looking for a cushy corporate job where nothing gets done, this is not the place. If you want to be part of a winning team and make a real difference, read on.
This role is in-office 5 days a week in San Francisco.
Your Day-to-Day
  • Build and maintain high-performance, responsive web applications using React and Next.js
  • Design and implement end-to-end features across frontend and backend systems
  • Work closely with backend engineers to integrate APIs, real-time systems, and voice AI workflows
  • Own UI/UX quality-craft fast, intuitive, and reliable user experiences
  • Manage state effectively across complex applications (server + client state)
  • Optimize frontend performance (latency, rendering, caching, edge delivery)
  • Build internal tools and dashboards for monitoring, debugging, and controlling AI agents
  • Write clean, maintainable, and well-tested code across the stack
  • Debug production issues and continuously improve reliability and usability
  • Contribute to system design, architecture decisions, and product direction
Qualifications
  • 5+ years of experience building production applications
  • Strong experience with React and Next.js
  • Experience building full-stack applications (API design, backend integration)
  • Solid understanding of TypeScript, modern frontend tooling, and state management
  • Experience working with APIs, real-time systems, and async data flows
  • Understanding of performance optimization and scalable frontend architecture
  • Familiarity with cloud environments, CI/CD, and modern deployment workflows
  • Strong product sense and attention to detail
  • Clear communicator who can work across teams
Our Software Stack
  • Frontend: React, Next.js, TypeScript
  • Backend: Python, microservices, async systems
  • Cloud & Infra: AWS, GCP, Kubernetes, Redis
  • Databases: Firebase, Supabase
  • Observability: Datadog, logging, metrics, tracing
  • Voice AI: SIP, real-time call handling, LLM orchestration
  • Other: CI/CD, testing, resilient architecture
Why Join Phonely?
We're a team of ex-athletes, founders, and builders. Low ego, high standards. We believe life isn't about taking the easy road - it's about pushing yourself to see what you're capable of.
Working here feels like a team:
  • We eat meals together (company-paid)
  • We run, hike, and surf
  • We travel together (Airbnbs in places like the Rockies, Costa Rica, Indonesia-multiple times a year)

We are deeply customer-obsessed and focused on building something we actually want to use. We're tackling voice AI problems that haven't been solved before, with a goal of building something 1M+ businesses love.
