About the Role Ontra is seeking a Senior 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. We're looking for someone who thrives in ambiguity: you can take a loosely defined problem, figure out the right approach, make smart trade-offs, and ship something that works well for users and the business. You’ll have practical experience with AI and LLMs, both as tools in your own workflow and in building product features. If you are an independent, self-motivated innovator with a sense of ownership, someone who thrives in developing iterative solutions and can work either solo or collaboratively with one other engineer to deliver continuous improvements, we’d love to get to know you! What You’ll Do

• Build with AI: Ship AI-powered product features and use AI tools across your own workflow, from prototyping to code review.

• Develop and Scale: Build, implement, and maintain a web-based application from the frontend to the backend using Ruby on Rails and React.

• 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 cross-functional 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).

• AI Fluency: Daily use of AI coding tools is required, along with the ability to review, verify, and reject AI output and to know when not to trust it. Preferred depth includes having built LLM features in production (RAG, agents, prompting, evals).

• 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.
