  • Investigating issues and improving system reliability
  • Collaborating on integrations and enhancements
  • Supporting users and resolving technical challenges
  • Building internal tooling where needed

  • Strong backend engineering fundamentals (Java experience ideal)
  • Experience working on complex systems
  • Comfortable working in Linux environments
  • Engineers who enjoy understanding how things work under the hood
  • Self-sufficient, proactive mindset

  • Remote-first, globally distributed team
  • High trust, low ego engineering culture
  • Strong focus on quality and continuous improvement
