Our AI-first approach is dedicated to building world-class solutions across product development, engineering, and business growth. We pride ourselves on partnering with visionary founders from prestigious networks such as 8VC and Action Capital, working alongside experienced operators who are building the next generation of venture-backed companies.
  • You will be instrumental in shaping a brand-new, greenfield project designed to revolutionize the way tastemakers, including travel agents and content influencers, operate. This initiative involves constructing a next-generation platform from the ground up, meticulously integrating advanced AI-powered features, an exceptionally intuitive user experience, and robust system-level integrations. This role is a unique opportunity to exercise significant technical and creative freedom, empowering you to explore novel concepts, develop innovative prototypes, and ultimately deliver groundbreaking solutions.
  • As a Senior Full-Stack Engineer, you will be a pivotal figure in the entire lifecycle of the platform's design and development. You will have the autonomy to experiment with emerging technologies, propose imaginative solutions, and architect novel experiences that challenge conventional industry practices. Your collaboration will be close and continuous with the Product and Engineering Lead, as well as other key stakeholders, working together to explore strategic options and bring the product vision to life.
  • Your core responsibilities will encompass the full spectrum of software development. This includes designing, building, and maintaining highly scalable full-stack applications. You will primarily utilize a modern tech stack featuring TypeScript, React, Node.js, PostgreSQL, and vector databases, alongside other state-of-the-art technologies essential for AI/LLM product development. A significant focus will be placed on developing sophisticated AI/LLM-powered features aimed at dramatically enhancing user productivity and delivering deeply personalized experiences.
  • You will actively collaborate with product stakeholders, playing a crucial role in defining and executing the overarching technical vision and strategy for the platform. This involves not just implementation but also strategic thinking and contribution to the product roadmap. A key aspect of your role will be to lead experiments, develop prototypes, and build proofs-of-concept to rapidly validate innovative ideas and ensure we are on the right track before committing to full-scale development.
  • Seamless integration with essential third-party services, such as those provided by Google and Microsoft, will be a critical component of your work. This includes ensuring secure and efficient authentication mechanisms and smooth workflow integrations that enhance the platform's utility and reach. Furthermore, you will be responsible for upholding the highest standards of code quality, ensuring optimal performance, and guaranteeing the scalability of the application across the entire technology stack. This involves proactive monitoring, performance tuning, and architectural considerations for future growth.
  • This role demands a proactive and self-driven individual who can thrive in an environment characterized by high autonomy and the inherent challenges and opportunities of a greenfield, early-stage project. You will be empowered to make significant technical decisions and contribute directly to the success of a product poised to make a substantial impact in its market. Your ability to translate complex requirements into elegant, efficient, and scalable technical solutions will be paramount. You will be part of a global, innovative team dedicated to building a truly game-changing product, offering unparalleled visibility and the chance to shape the future of a burgeoning industry.

🎯 Requirements

  • Strong proficiency and hands-on experience with TypeScript, React, Node.js, and PostgreSQL.
  • Proven track record of successfully building and shipping end-to-end products from conception to deployment.
