About the job

Requirements
  • At least 4 years in an implementation, solutions engineering, or technical account management role at an API-first company.
  • Hands-on experience with REST APIs and webhooks, including testing endpoints, reading payloads, and debugging integrations from logs.
  • Ability to read code well enough to trace a bug to a file and a pull request, and to write SQL to answer questions about customer data.
  • Evidence of building processes where none existed, such as a playbook, SLA model, or runbook set, and getting a team to adopt them.
  • Professional fluency in spoken and written Spanish and English.
  • Ability to write clearly under pressure in Slack messages and tickets.
Responsibilities
  • Represent the customer on technical gaps by identifying patterns across accounts and turning them into evidence.
  • Field technical questions during pre-sales and guide integrators from the first technical call through go-live, providing same-day endpoint-level answers and workarounds.
  • Serve as the named technical contact for top-tier accounts, run shared channels, own escalations to banking and compliance partners, and close loops in writing.
  • Monitor and resolve integration bugs quickly, root-cause issues before escalation, file actionable engineering tickets, and open pull requests for small fixes.
  • Translate integrator pain into product feedback, quantify customer impact in feedback tickets, hold a regular review with Product, and contribute to specifications before features ship.
  • Build the implementation playbook, issue SLAs, partner escalation runbooks, and SOPs for recurring edge cases.
  • Support rollout of new products and policy changes, and resolve bugs affecting integration customers.
Desired Qualifications
  • Experience with payments, banking, or stablecoin infrastructure.
  • Portuguese.
  • Experience with KYC/KYB vendors such as Sumsub and related questionnaires, document resubmission, and verification-level flows.
  • Familiarity with SEPA/SWIFT return codes, correspondent-bank rejections, or local payment rails in Latin America.
  • Experience shipping small fixes or documentation pull requests in a production codebase.
