About Us

At True Path Leads, we're building the next generation of performance marketing infrastructure. Our platform processes millions of events daily across a wide ecosystem of integrations and partner channels. We're looking for a Senior Frontend Developer who takes ownership of what they build — from architecture decisions to pixel-level details. You'll work closely with product and design to ship high-quality interfaces used by real people every day.

Tech Stack

React · TypeScript · Tailwind CSS · REST APIs · JavaScript (native) · HTML & CSS · Shadow DOM · Web Components

What You'll Do

  • Build and maintain complex, production-grade React apps with TypeScript.
  • Develop embeddable, framework-agnostic widgets using native Web APIs and Shadow DOM.
  • Design component libraries and UI systems that scale.
  • Integrate with REST APIs and collaborate on API contracts with backend.
  • Participate in architecture discussions and technical roadmap decisions.
  • Keep a strong focus on performance, accessibility, and browser compatibility.

What We're Looking For

  • 5+ years of frontend development, at least 2 years in React.
  • Deep JavaScript fundamentals — closures, event loop, prototype chain — you know what happens under the hood.
  • Strong understanding of the browser rendering pipeline, Shadow DOM, and Web Components.
  • Experience building third-party embeddable widgets or SDKs.
  • TypeScript proficiency — types that actually help, not just satisfy the compiler.
  • Solid HTML/CSS — complex layouts without reaching for a library.
  • Clear communicator, works well in a distributed async team.

Nice to Have

  • Experience with Lottie / SVG animations and web animation APIs.
  • Familiarity with performance profiling tools (Lighthouse, Chrome DevTools).
  • Experience contributing to or maintaining a design system.
  • Background in ad-tech, lead generation, or performance marketing platforms.

What You'll Get

  • Fully remote position with flexible working hours.
  • High ownership — architecture decisions are yours to drive.
  • Work on interfaces used by real users at real scale.
  • Fast-paced startup environment with no bureaucracy.
  • Competitive compensation based on experience and skill set.
  • Clear growth path toward Frontend Architect or Tech Lead roles.
