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.
