Requirements - Accessibility for conversational UIs: live-region streaming, captions/transcripts for voice, keyboard and screen-reader support. - Knowledge of observability for frontend: Sentry, logging, analytics events, debugging production issues. - Startup experience where autonomy, ownership, and speed matter. - Knowledge of CI/CD pipelines and containerisation with Docker. - Expertise with subscription-based or B2B/B2C SaaS businesses. Benefits - Market salary. - 20 workdays/year paid vacation. - Full-time remote work with flexible working hours. - Fast-paced, product-driven environment with real ownership and autonomy. - Opportunity to shape architecture and tech stack in a VC-backed startup from the early stages. - Close collaboration with a strong product team (PM, Design, Growth). - A culture of transparency, minimal bureaucracy, and quick decision-making. - Smart, ambitious teammates who value impact over process.
