We are looking for a Tech Lead (Ruby) to own the technical direction of one product team.
This role is for a strong backend engineer who cares deeply about engineering quality, system reliability, and good development practices — not just writing features.

You will be responsible for architecture, code quality, delivery process, and helping the team grow technically.

Requirements (Must Have):
 

• Strong experience with Ruby in production systems.
• Solid backend engineering background:
  • Experience with SQL and NoSQL databases.
  • Understanding of data modeling, indexing, transactions, and performance trade-offs.
• Good understanding of modern infrastructure:
  • Containers and Kubernetes (how applications run, scale, fail, and recover).
  • Observability stack: metrics (Prometheus), dashboards (Grafana), logs (ELK / Loki).
• Strong engineering culture mindset:
  • Automated testing is mandatory (unit, integration, CI).
  • Ownership of code quality and enforcement of standards.
  • Experience running meaningful code reviews.
• Experience working in product teams with real production responsibility.
• Ability to own technical decisions and communicate clearly with engineers and stakeholders.
   

Responsibilities:
 

• Own the technical direction of one product team (architecture, quality, scalability, reliability).
• Lead development in a Ruby-based stack while applying strong backend engineering practices.
• Drive engineering excellence:
  • Code reviews, coding standards, and best practices.
  • Strong focus on automated testing (unit, integration, CI quality gates).
  • Improving observability, reliability, and operational maturity.
• Participate in release planning and execution:
  • Coordinate releases, assess risks, ensure smooth deployments.
  • Work closely with product, QA, and infrastructure teams.
• Design and evolve system architecture:
  • Data modeling, database design, performance, scalability.
  • Infrastructure-aware design (containers, orchestration, monitoring).
• Mentor engineers and raise the overall engineering bar of the team.
• Actively participate in technical decision making and long-term improvements.

Nice to Have:
 

• Experience with high-load or distributed systems.
• CI/CD pipelines, release automation, progressive delivery.
• Experience improving legacy systems and managing technical debt.
• Cloud experience (AWS / GCP / Azure).
• Experience mentoring or leading engineers.
   

What We Value:
 

• Engineering quality over short-term hacks.
• Strong ownership and accountability.
• Clear communication and pragmatic decision making.
• Curiosity and continuous improvement mindset.

We Offer:

• Opportunities for professional growth and development.
• Work in an innovative and fast-growing industry.
• A friendly and supportive team environment.
