About the Role Ontra is seeking a Senior Full Stack Software Engineer reporting to one of our Engineering Managers. We're looking for someone excited to design innovative prototypes, develop intuitive user experiences, and collaborate with cross-functional teams to build our cutting-edge products. If you are an independent, self-motivated innovator with a sense of ownership, someone who thrives in developing iterative solutions and has the ability to work either solo or collaboratively with one other engineer to deliver continuous improvements, we'd love to get to know you! To foster team connection and collaboration, this role requires being present in either our Santa Barbara or San Francisco office up to once a quarter for team meetings and off-sites. As such, we are only considering candidates who are currently based in California. What You'll Do * Develop and Scale: Build, implement, and maintain a web-based application from the frontend to the backend using Ruby on Rails and React.JS. * Ownership and Accountability: Take full responsibility for the progress and success of the project, driving key decisions and problem-solving independently or with minimal guidance. * Iterative Improvement: Continuously ship and improve code by seeking stakeholder feedback, responding effectively to suggestions, and implementing changes rapidly. * Stakeholder Engagement: Actively engage with stakeholders to understand their needs, gather insights, and incorporate feedback into the product development process. * Collaboration: Work closely with crossfunctional teammates to align on development strategies, ensuring seamless integration of ideas and efforts in building the prototype. What You'll Bring * Experience: 5+ years as a full-stack software engineer working with MVC frameworks (e.g., Ruby on Rails, Python with Flask, Java with Spring). * Project Development: Demonstrated history of successfully building projects from inception to completion. * Independence: Capable of working solo or with one other engineer, showcasing a strong sense of ownership and accountability for the project. * Iterative Approach: Skilled in developing iteratively, incorporating stakeholder feedback to refine and improve the product continuously. * LLM Familiarity: Proficiency with coding assistant LLMs such as CoPilot or Cursor. Experience in integrating LLMs into products for data extraction and summarization to solve business needs is a plus.
