Senior Ruby on Rails Developer

About Us

Smirnov Labs is a fast-growing engineering company founded by an ex-Googler. We help product teams launch and scale quickly by leveraging modern technology and AI-assisted development.

Our projects are diverse — we partner with clients at the earliest stages and own the technical delivery end-to-end.

We're a small, senior-heavy team where every engineer has real impact. No bureaucracy, no hand-holding — just sharp people shipping fast.

What You'll Do
 

• Own features end-to-end: from architecture and implementation to deployment and support
• Build and ship web applications using Ruby on Rails
  Design and maintain APIs, services, and data layers (PostgreSQL, Redis, Sidekiq)
• Deploy and operate services on AWS with Docker
• Write clean, well-tested code with RSpec                                         
• Communicate with the CTO and client-side engineering team directly — no layers in between
• Use AI-assisted development tools (Claude, Cursor, GitHub Copilot) as part of your daily workflow
• Work across diverse projects — different domains, different challenges    

What We're Looking For
 

• 4+ years of professional backend or full-stack development experience
• Strong Ruby and Rails skills (Rails 6+)
• Solid hands-on experience building RESTful and/or GraphQL APIs
• Production experience with PostgreSQL, Redis, Sidekiq, AWS, Docker
• Familiarity with frontend basics (HTML, CSS, JavaScript) — enough to work with Hotwire/Turbo or integrate with a JS frontend
• Comfort working in US timezone (overlapping working hours required)
• Upper-Intermediate or higher English
• Ability to own and drive features independently with minimal supervision
• Go or TypeScript experience is a plus

What We Offer

• Competitive salary above market average
• Fully remote work
• Flat structure — work closely with the CTO, no middle management
• Diverse and technically challenging projects
• Modern AI-powered development workflow
• Small team culture — your voice matters, your code ships
• Paid vacation and sick leave
• Flexible schedule within US timezone overlap
• Professional and career growth through real ownership, not courses and certificates
