About Telnyx

Telnyx is an industry leader that's not just imagining the future of global connectivity—we're building it. From architecting and amplifying the reach of a private, global, multi-cloud IP network, to bringing hyperlocal edge technology right to your fingertips through intuitive APIs, we're shaping a new era of seamless interconnection between people, devices, and applications.

We're driven by a desire to transform and modernize what's antiquated, automate the manual, and solve real-world problems through innovative connectivity solutions. As a testament to our success, we're proud to stand as a financially stable and profitable company. Our robust profitability allows us not only to invest in pioneering technologies but also to foster an environment of continuous learning and growth for our team.

Our collective vision is a world where borderless connectivity fuels limitless innovation. By joining us, you can be part of laying the foundations for this interconnected future. We're currently seeking passionate individuals who are excited about the opportunity to contribute to an industry-shaping company while growing their own skills and careers.

About you:
You relish the interaction details that make products delightful, the technical challenges involved in building a highly performant web app, and the research, experimentation and coaching that goes into applying better systems of abstraction in a collaborative codebase. Product intuition and empathy with the user are as much of a necessity as applied technical knowledge of best practices in frontend engineering.

We are seeking an experienced Front-End Engineer with a strong background in React.js, Next.js, and modern DevOps processes to join our growing engineering team. This role is ideal for someone who thrives at the intersection of development and deployment, with a keen eye for performance, scalability, and maintainability.

You’ll play a pivotal role in enhancing our user interfaces, leading front-end best practice. If you're passionate about creating seamless, responsive, and robust web applications while ensuring smooth deployment pipelines, we’d love to meet you.

Key Responsibilities
  • Build, maintain, and optimize modern web applications using React.js and Next.js.
  • Collaborate closely with designers, product managers, and backend engineers to implement engaging user experiences.
  • Manage deployment workflows using Vercel and CI/CD pipelines to ensure fast, reliable releases.
  • Participate in end-to-end DevOps processes, including monitoring, logging, and performance optimization.
  • Write clean, maintainable, and well-documented code that follows industry best practices.
  • Actively participate in code reviews, architecture discussions, and technical planning.
  • Stay up-to-date with evolving front-end technologies and propose improvements to our tech stack and workflows.
  • Lead and contribute to the migration of our styling system from Stitches CSS to Tailwind CSS.
Qualifications
  • 4+ years of professional experience developing and deploying production-grade web applications using Next.js and React.js.
  • Deep understanding of Next.js features like server-side rendering (SSR), static site generation (SSG), API routes, and incremental static regeneration (ISR).
  • Proven experience deploying applications on Vercel and working with its platform features (e.g., previews, analytics, edge functions).
  • Hands-on experience with CI/CD pipelines and modern DevOps practices in a front-end context.
  • Strong familiarity with CSS-in-JS solutions (ideally Stitches) and hands-on experience or enthusiasm for Tailwind CSS.
  • Proficient in writing unit, integration, and end-to-end tests using tools like Jest or similar.
  • Solid understanding of performance optimization techniques for web applications.
  • Comfortable working in Agile or Lean development environments with tools like Jira, GitHub Projects, or similar.
Nice to Have
  • Experience integrating front-end applications with headless CMSs such as Contentful and Strapi.
  • Familiarity with TypeScript and adopting type-safe coding practices.
  • Exposure to edge computing concepts, CDN configuration, or security best practices for front-end applications.
  • Degree in Computer Science or Software Engineering, or a very related field.
