Senior Rails Engineer

The Receptionist, located in the RiNo district in Denver, CO, is the industry-leading, cloud-based Visitor Management Solution (VMS) that automates visitor check-in and helps reduce the chaos of the modern front office. We’re currently looking for a Senior Rails Engineer to join our growing team. 

The Senior Rails Engineer will play a key role in expanding and maintaining our core product — the web application that powers our iPad-based visitor management solution. You’ll collaborate across the company to deliver high-impact features, optimize system performance, and keep our codebase clean, testable, and scalable.

This is a great opportunity for someone who’s excited about building tools that make people's lives easier, enjoys thinking through long-term architecture, and wants to be part of a supportive, values-driven team that believes in working smart, staying curious, and laughing daily.

What You’ll Be Doing

• Design, build, and test new features in our Rails application — the hub for customers configuring their iPad check-in experience
• Collaborate with engineering, product, and leadership teams to scope, plan, and deliver value-driven work
• Write clean, well-tested, and maintainable code that balances present needs with future flexibility
• Build and improve third-party integrations to make our customers’ visit data even more powerful
• Maintain and enhance system performance, using tools like APMs and error tracking
• Participate in code reviews to ensure quality, security, and consistency across the team
• Share ideas, ask questions, and bring a product-focused mindset to everything you do
• Demonstrate alignment with our core values — the FABRIC of everything we do: Fun, Authentic, Bold, Respectful, Innovative, and Collaborative

Requirements

• 4-5 years of experience building and maintaining full-stack web applications using Ruby on Rails
• 2 years of current Rails experience
• Strong proficiency with RESTful JSON APIs, both building and consuming
• Comfortable working across the stack — backend design and frontend usability
• Passion for the customer experience and a willingness to engage in user feedback
• Curiosity-driven approach to problem solving — you like to figure out how things work
• A “get it done” mindset that balances persistence with healthy boundaries
• Commitment to quality, testing, and debugging — you care about reliability and trust
• Experience with third-party integrations (webhooks, JSON APIs, etc.)
• Basic understanding of mobile platform constraints and opportunities

Nice-to-Have

• Experience with major Rails upgrades (e.g., Rails 5 → 6 or 6 → 7)
• Experience building scalable systems (handling hundreds of requests per second)
• Familiarity with subscription billing tools like Stripe or Recurly
• Exposure to iOS development or building for mobile platforms

Tech Stack

• Languages: Ruby, ERB, JavaScript
• Frameworks & Tools: Rails, Minitest, ViewComponents, Tailwind, StimulusJS, Hotwire
• Infrastructure: PostgreSQL, Redis, Sidekiq
• OS & Environment: macOS
