About the role We are seeking a technically skilled Support Engineer to serve as the critical link between our customer-facing support team and our Engineering and Product organizations. This role owns the full lifecycle of complex technical escalations; from front-end triage and backend investigation to defect documentation and custom resolution, ensuring that only thoroughly vetted, well-documented issues reach development. You will be the technical escalation for API, SmartView, and SQL-related issues, build custom SQL and API-based solutions to resolve complex customer problems, and provide hands-on technical guidance to Tier 1 specialists.

- Author detailed bug tickets and track defects through resolution, maintaining clear documentation of reproduction steps, expected behavior, and workarounds.
- Serve as the primary owner of all API, SmartView, and SQL-related support issues, diagnosing and resolving complex technical problems end-to-end.
- Develop custom solutions using SQL and internal APIs to resolve complex, customer-facing issues that fall outside standard support workflows.
- Provide technical guidance to Tier 1 Support Specialists, assisting with complex cases and building team knowledge.
- Rigorously test and reproduce escalated issues to confirm defect behavior, validate fixes, and identify interim workarounds that minimize customer impact.
- Collaborate with Engineering and Product teams by delivering well-documented, fully triaged defect reports that accelerate resolution and reduce back-and-forth.
- Communicate with customers via phone, email, or chat regarding complex or escalated support issues.
Qualifications- Bachelor's degree in Computer Science, Information Systems, or a related technical field or equivalent work experience.
- 5+ years of experience in a technical support, support engineering, or software QA role, ideally in B2B SaaS or Fintech.
