Staff Product Engineer (Ruby on Rails)

STAFF PRODUCT ENGINEER (RUBY ON RAILS)

We are looking for a senior Ruby on Rails engineer to become the technical backbone of our product. You'll own the hardest PRs, raise the bar for the entire codebase, and eventually take technical load off the CEO. This is not a management role. It's a hands-on, high-trust position for someone who can ship production code across every part of the product.

ABOUT the company

The company [link for members] is a real-time SERP API delivering structured data from 100+ search engines and sources, including Google Search, Google Shopping, Google Jobs, Bing, Baidu, YouTube, Amazon, and many more. We power production workloads for Fortune 500 companies and fast-moving startups who need reliable search data at scale.

We're a lean, profitable, bootstrapped team. No VC pressure, no bloat. Just engineers shipping real products to real customers.

🎯 WHY JOIN US?

• Own the product. You'll work across the entire codebase. Billing, API, dashboard, enterprise features, internal tools. Everything.

• High trust, high impact. The CEO/CTO currently reviews the hardest PRs. You'll take that over.

• Shape the technical direction. Introduce better patterns, raise code quality, build compounding systems.

• Work directly with the CEO/CTO. No layers. Direct collaboration on product and technical decisions.

• Bootstrapped and Profitable. We answer to customers, not investors.

We are searching for someone who can eventually replace the CEO/CTO's technical load. Not a manager. A builder who ships with an extremely high bar.

🛡️ the company VALUES

• We do everything the Rails Way [link for members] If you don't like DHH's style, this may not be the place for you.

• We embrace the one person framework [link for members]

• We hire Managers of One [link for members] We trust you to figure it out.

• Remote-only. Async-first. Results-driven.

• Transparency. No politics.

💻 TECH STACK

• Ruby on Rails 8.1

• Ruby 3.4

• Hotwire (Stimulus.JS + Turbo)

• TailwindCSS (TailwindUI components)

• PostgreSQL

• Redis

• Sidekiq

• Stripe

• Terraform + AWS

We use Cursor, Claude, ChatGPT, Intercom, GitHub, and Slack daily. We ship multiple times a day with CI/CD.

🤖 YOU CONTROL AI, AI DOESN'T CONTROL YOU

We ship faster because we use AI tools aggressively. Cursor and Claude. But you own the output. If you can't evaluate what AI produces, you're not ready for this role. You'll also help introduce more AI into how we build and ship.

💪 WHAT YOU'LL DO

• Own the hardest PRs. Complex features, tricky refactors, performance-critical code. The stuff that requires senior judgment.

• Review other engineers' PRs. Raise the bar. Catch issues before they ship. Mentor through code review.

• Build enterprise features. SAML, SCIM, audit logs, permissions. Whatever enterprise customers need.

• Work on billing and payments. Stripe integrations, subscription logic, usage-based billing.

• Create and iterate on product features. API playground, dashboard improvements, developer experience.

• Develop in-house algorithms. We build custom solutions. You'll design and implement them.

• Debug and optimize performance. Memory profiling, CPU profiling, query optimization. You find the bottleneck and fix it.

• Work with native gems and low-level bindings when needed. Different architectures, compilation issues, C extensions.

• Ship frontend with good design sense. We use TailwindUI. You should be comfortable building clean, functional UI.

• Maintain security standards. Understand common vulnerabilities. Review code with security in mind.

• Stay current with Rails and AI. Know what's new. Adopt what makes sense. Always look for compounding benefits.

As you grow into the role

• Oversee other engineers' work.

• Make architectural decisions.

• Potentially gain production access and work with Terraform.

• Lead new projects or pivots.

🔥 THE HARD PARTS

This role is not for everyone. Here's what makes it hard

• Broad scope. You're not specializing in one area. You touch everything. Billing, auth, API, frontend, infra.

• High bar. Your code needs to be excellent. You're setting the standard.

• Ambiguity. Sometimes you'll decide what to build, not just how to build it.

• Responsibility. When you ship something, you own the outcome. No one else to blame.

• Fast pace. We ship daily. We expect results, not activity.

If you want a narrow role with clear boundaries, this isn't for you.

✨ ABOUT YOU

• Many years of Ruby on Rails experience. This is not a mid-level role. You've built and shipped production Rails apps.

• Proven track record. You can point to systems you've built, problems you've solved, code you're proud of.

• Stripe experience. Required. You've worked with Stripe billing, subscriptions, webhooks.

• Product thinker. You don't just build what you're told. You think about what customers need and why.

• Good design sense. You can ship clean UI with TailwindCSS. Not pixel-perfect designer, but functional and polished.

• Security-minded. You understand authentication, authorization, common vulnerabilities.

• Up to date. You follow Rails releases, Ruby updates, AI developments. You're curious about what's next.

• Compounding mindset. You look for improvements that pay dividends over time, not just quick fixes.

• Comfortable with performance debugging. Memory profiling, flame graphs, query analysis. You've optimized slow systems before.

• Great writer. PRs, docs, code comments. Clear communication matters.

• Self-directed. You don't need daily standups to stay productive.

• Fluent in English, written and spoken.

• BSc or higher in CS or equivalent technical field.

Nice to have

• Terraform experience.

• AWS infrastructure familiarity.

• Experience at scale (billions of requests).

• Open-source contributions in the Rails ecosystem.
