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.

Kaleris is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
