Full-Stack Engineer, Taktile

• If you've worked with modern JavaScript/TypeScript, have experience building front-end applications, and are excited about developing SDKs or developer-facing products that run in other people's browsers, we'd love to talk
• Hybrid role based in Berlin. We collaborate in person regularly and don't offer remote-only for this position
• Fluent English required. You'll write design docs, review PRs with context, and occasionally join customer calls
• Solid engineering fundamentals across the full stack: you're comfortable working with both APIs and responsive, accessible front-end experiences
• Good understanding of how browsers work: the DOM, security models (CSP, CORS, iframe sandboxing), caching, script loading, and performance
• Comfortable working in production environments and willing to participate in incident response as part of a team rotation
• 2–4 years of professional software engineering experience, ideally working on web applications or developer-facing tools
• Production experience with TypeScript/JavaScript on both client and server. You've built modern front-end applications and have a solid understanding of bundling, tree-shaking, and cross-browser compatibility
• Familiarity with iframe-based architectures, postMessage communication, or sandboxed execution environments is a strong plus
• Some backend development experience (Python is a plus) — you're able to work with APIs and services that support the client-side layer
• Prior experience with public cloud providers (preferably AWS)
• Regardless of whether they tick all the boxes. We're looking for someone who will add to our culture, not just fit within it. We strongly encourage individuals from groups traditionally underestimated and underrepresented in tech to apply
