đŸŒ± About the Role
We’re partnering with a fast-growing startup on a mission to build a high-impact product used by thousands of customers. They’re now looking for a hands-on Ruby Tech Lead to step in on a contract basis and drive technical direction, delivery, and team alignment during a key growth phase.

This is a high-ownership role where you’ll influence architecture, mentor engineers, and help scale both the platform and engineering practices.

🛠 What You’ll Be Doing
  • Lead the design and delivery of scalable, high-performance systems using Ruby (Ruby on Rails)
  • Provide technical leadership to a small but growing engineering team
  • Own architecture decisions and help evolve the platform as it scales

  • Drive best practices around code quality, testing, and deployment
  • Contribute hands-on to the codebase when needed
  • Help shape the engineering roadmap and delivery strategy

✅ What We’re Looking For
  • Strong experience as a Tech Lead or Senior Engineer in startup or scale-up environments
  • Deep expertise in Ruby / Ruby on Rails
  • Proven experience with system design, architecture, and scaling applications
  • Comfortable working in fast-paced, ambiguous environments
  • Experience mentoring or leading engineers
  • Familiarity with modern cloud environments (AWS, GCP, or similar)
  • Strong communication skills and the ability to influence non-technical stakeholders

⭐ Nice to Have
  • Experience in early-stage startups or high-growth scale-ups
  • Background working on consumer or marketplace products
  • Exposure to microservices, event-driven systems, or API-heavy platforms
  • DevOps or CI/CD exposure

💡 Why Join
  • Immediate impact in a high-growth startup environment
  • Work alongside an ambitious and collaborative founding/leadership team
  • Flexibility with remote-first setup in the UK
  • Opportunity for contract extension or future permanent role
