  • Design and implement integrations with SQL and NoSQL databases
  • Participate in code reviews, sprint planning, technical discussions, and troubleshooting sessions
  • Proactively identify and escalate blockers, risks, and dependencies rather than waiting for others to surface them

  • Familiarity with Terraform/IaC and CI/CD tools (GitHub Actions, Jenkins, or similar)
  • Comfortable in Linux environments

CS Fundamentals
  • Strong grounding in data structures/algorithms, concurrency, distributed systems, and system design
