As a small yet growing startup, we’re looking for a passionate and experienced Ruby on Rails software engineer to become the fourth member of our tight-knit team. This is an opportunity where your contributions won’t just be felt – they’ll help shape the direction of our company and its products.

Your Role

We’re seeking a dedicated candidate for a remote and full-time position. As a company, we value great design and code, and pay close attention to detail throughout the product development process. If you’re passionate about writing elegant, well-organized code, this may be the perfect opportunity for you.

You’ll be working directly with our CTO to expand our capabilities, delivering faster and more efficient solutions to our clients. Apart from coding, you’ll also engage in strategic discussions, contribute to architectural decision-making, and influence the roadmap of our product.

Your Responsibilities

  • Enhance our mission and expand our product’s capabilities by developing new integrations with third-party services and APIs. This includes eCommerce platforms, Point-of-Sale (PoS) systems, CRMs, and more. Your contribution will be instrumental in broadening our product’s scope and enriching our platform’s connectivity options, directly impacting the way our clients do business.
  • Building new features and functionality for both the frontend and backend.
  • Optimize existing complex backend processing jobs when required.
  • Collaborate with the CTO in identifying parts of the system that need fixing and optimization.
  • Participate in building new app features and our new dashboard.
  • Assisting in scaling efforts by performing benchmarks and optimizations as needed, and proposing changes to architecture design

Our Team

We are a distributed global team comprising of the CEO, CTO, and a Sales Executive. You’ll be our fourth addition, closely collaborating with the CTO and occasionally engaging with the rest of the team in meetings.

Our Stack

Ruby and Rails, Hotwire, TailwindCSS, PostgreSQL, ElasticSearch, Kubernetes clusters deployed to AWS, and GitHub.


You love the thrill of building a product from scratch, relishing the opportunity to influence its design decisions and future trajectory. You understand the importance of code structure and relationships when writing code. You recognize the occasional need for quick-fixes and are able to balance this with maintaining overall system integrity. You are independent and don’t require micro-management.
