• Design scalable, reliable services that support high-velocity product development.
• Dive deep into hard problems across performance, data modeling, stability, and APIs.

• Improve system reliability and developer experience through tooling, standards, and architecture.
  
  

What we are looking for:

• 6+ years in software engineering with strong evidence of owning complex systems.
• Deep proficiency in Node.js (clean backend architecture is key).
• Strong relational database fundamentals (PostgreSQL) and experience designing data models.
• Exceptional debugging skills and strong engineering judgment.
• Fast learner with the ability to ramp into new domains independently.
  
  

Nice to have:

• Experience with distributed systems, caching, messaging, or multi-tenant architectures.
• Experience integrating AI/LLM capabilities into backend systems.
• Infra or platform experience (observability, CI/CD tooling, APIs).

Why join us?

• Real ownership from day one. Drive decisions, shape ideas and make them work.
• Your fastest learning years. Build alongside founders and VPs in a space that moves weekly.
