About Octopi

Octopi is a modern SaaS platform helping cargo ports streamline their terminal operations. From small private ports to large commercial terminals, our cloud-based software brings transparency, efficiency, and collaboration to an industry that’s long been underserved by technology.

We’re a small, mission-driven team that believes in deep work, pragmatic engineering, and building software our customers love to use. As we continue to grow, we're looking for an experienced Senior Full-Stack Engineer to help us shape the next phase of Octopi.
What You’ll Do
• Lead the design, development, and delivery of new features and improvements in our Ruby on Rails application.
• Write clean, maintainable, well-tested code across the stack.
• Collaborate closely with Product Management, Customer Success and Onboarding teams to understand real-world customer needs and translate them into technical solutions.
• Own the quality, performance, and scalability of the application as we grow.
• Contribute to code reviews, technical planning, and architectural decisions.
• Continuously identify opportunities to improve the product and user experience.

What We’re Looking For
• 5+ years of professional software development experience.
• 4+ years working with Ruby on Rails in production environments.
• Strong understanding of relational databases and PostgreSQL in particular.
• Proficiency in front-end technologies: HTML, CSS, and a few flavors of javascript.
• Experience working with Git, GitHub, and modern development workflows.
• A pragmatic mindset with the ability to balance ideal solutions with business needs.
• Strong communication skills and the ability to work independently in a remote environment.
• A genuine curiosity about the maritime and logistics industry—or a willingness to learn.

Nice to Have
• Experience scaling a Rails application in production.
• Prior experience working in a SaaS startup or on B2B products.

Why You’ll Love Working Here
• A small, fast-moving team where your work has real impact.
• A culture that supports deep work and independent thinking.
• Interesting technical challenges in a global, real-world industry.
• Fully remote work with flexible hours.
