  • Participate in code reviews, technical design discussions, and architecture decisions
  • Contribute to improving engineering standards, tools, and processes

What You BringExperience

Ways of Working
  • Strong problem-solving skills and attention to detail
  • Ability to work independently while collaborating effectively across teams
  • Comfortable working in a fast-paced, high-growth environment
  • Ownership mindset with a focus on delivering high-quality, scalable solutions

Nice to Have

  • Familiarity with cloud platforms (AWS, GCP, or similar)
  • Experience with microservices architecture
  • Understanding of security and compliance considerations in financial systems
