đź“‹ Description

  • • Join EkLine, an innovative AI-powered platform revolutionizing the creation and maintenance of product, user, and API documentation. As a Senior Full Stack Engineer, you will play a pivotal role in shaping the future of our technology, working directly alongside the founders to design, build, and scale our cutting-edge solutions. This is a unique opportunity to make a significant impact in an early-stage startup environment, taking ownership from day one and delivering tangible value to our users.
  • • In your first 3-6 months, you will be instrumental in driving key product initiatives. Your primary focus will be on delivering multiple high-impact features that directly enhance customer workflows and streamline their documentation processes. You will be responsible for shipping robust, maintainable code written in TypeScript, React, and Node.js, ensuring comprehensive test coverage to guarantee reliability and stability. A critical objective will be to improve platform performance and scalability by at least 20%, directly contributing to a superior user experience. Furthermore, you will take the lead in making crucial technical decisions for new integrations and API enhancements, shaping the technical direction of the platform. A vital aspect of this role involves mentoring junior engineers, fostering their growth, and elevating the overall code quality and development velocity of the team.
  • • Your key responsibilities will encompass the end-to-end development, maintenance, and enhancement of our core web application and its various platform integrations. This includes building and meticulously optimizing RESTful APIs, ensuring seamless cross-system integration and data flow. You will collaborate closely with the founders on all facets of product design, architectural decisions, and the strategic roadmap, contributing your expertise to guide the company's technical vision. A paramount focus will be placed on ensuring the performance, scalability, and unwavering reliability of all systems, from the user interface to the backend infrastructure. You will be instrumental in implementing secure, scalable infrastructure leveraging Google Cloud services, ensuring our platform can grow with demand.
  • • This role also involves actively participating in code reviews, providing constructive feedback, and actively supporting the professional development and growth of junior engineers. You will be a key contributor to fostering a culture of technical excellence and continuous improvement within the engineering team. The ideal candidate will possess a strong ownership mindset, demonstrating a proactive approach to problem-solving and a commitment to seeing tasks through to completion. Excellent communication skills are essential for effective collaboration with the founders and the wider team, especially given the remote nature of the role and the need for daily communication with our U.S.-based team. A dedication to continuous learning and staying abreast of the latest technologies is highly valued.
  • • We are particularly interested in candidates who have experience utilizing AI tools to enhance engineering productivity. This aligns with EkLine's core mission of leveraging AI to accelerate documentation processes. Your ability to integrate and leverage these tools will be a significant asset. The role requires a minimum of 6 hours of overlap with Pacific Standard Time (PST) working hours (9 AM - 3 PM PST), ensuring effective real-time collaboration with the U.S. team. This role offers a unique opportunity to be at the forefront of AI-driven documentation solutions, contributing to a product that empowers engineering and product teams with unprecedented control, flexibility, and efficiency through a docs-as-code approach.
