About The Role

We are looking for a skilled Senior Software Engineer with hands-on Ruby on Rails expertise to join our team. This is not a Rails-only role — the ideal candidate is someone who is strong in Rails but equally comfortable working across our broader backend stack (https://jobeax.com/link/JSd7UYCSg572jJDY, microservices, and other services), and can move fluidly between them based on what the team needs. The successful candidate will be responsible for developing and maintaining the back-end infrastructure of our B2B SaaS product, with a strong understanding of software architecture, database design, and server-side programming. Additionally, the candidate should have experience working with cloud-based infrastructure (AWS, preferably) and be able to develop highly scalable and secure systems.

Key Responsibilities

• Collaborate with the development team, product managers, and designers to understand business requirements and contribute to technical specifications and software solutions.

• Design, develop, test, and deploy back-end components across our Ruby on Rails and non-Rails (e.g. https://jobeax.com/link/JSd7UYCSg572jJDY) services — this role is expected to work across the backend stack, not within a single framework.

• Work with front-end engineers to develop APIs that facilitate smooth data flow and system interoperability.

• Contribute to system design discussions, weighing in on architecture, scalability, and trade-offs for new and existing services.

• Optimize code, conduct testing, and follow best practices to ensure the reliability, performance, and security of the application.

• Learn and contribute to the development and maintenance of cloud-based infrastructure, preferably using AWS, ensuring scalability, high availability, and disaster recovery.

• Use AI-assisted development tools (e.g. Cursor or similar) thoughtfully as part of the engineering workflow — going beyond surface-level usage to actually improve code quality, review rigor, and team productivity.

• Collaborate with cross-functional teams to ensure successful product launches and provide support when needed.

• Participate actively in Agile development practices, including sprint planning, stand-ups, and retrospectives.

• Contribute to the refinement of user stories, provide effort estimations, and prioritize tasks to ensure timely delivery.

• Participate in code reviews to maintain code quality, receive constructive feedback, and adhere to best practices.

• Stay updated with industry trends and emerging technologies, evaluating their potential benefits for the product and the development team.

• Actively contribute to continuous improvement initiatives by suggesting process enhancements and implementing approved changes.

Requirements / Qualifications

• 3–7 years of backend development experience, with strong, hands-on Ruby on Rails expertise. Exceptionally strong candidates with ~2 years of experience will also be considered.

• Demonstrated ability and willingness to work across multiple backend services/frameworks (e.g. Rails and https://jobeax.com/link/JSd7UYCSg572jJDY) — candidates seeking a Rails-only scope are not a fit for this role.

• Strong IC (individual contributor) who can join any existing project and start contributing within a week's time.

• Can build and integrate REST APIs in Rails.

• Experience working with async processors such as Sidekiq, Resque, ActiveJob, or Shoryuken.

• Solid understanding of Rails object-oriented programming concepts.

• Comfortable engaging in system design discussions — able to reason through architecture, scale, and trade-offs, not just implement to spec.

• Genuine, hands-on experience using AI tools in development — able to speak concretely to workflow, prompting practices, code review process with AI-assisted code, and problems solved (not just familiarity with a tool name).

• Ability to speak in depth about past project ownership — real depth of involvement matters more than breadth listed on a resume.

• Familiarity with front-end technologies such as HTML, CSS, and JavaScript is a plus.

• Exposure to cloud-based infrastructure, preferably AWS services, and a strong desire to learn about scalable and secure system development.

• Effective problem-solving in ambiguous and complex technical scenarios.

• Strong computer science fundamentals and automation testing technologies.

• Focus on customer satisfaction and holistic user experience.

• Excellent communication, collaboration, and mentoring abilities.
