About the job
We are looking for someone to join Credix as a Sales Engineer. You will own the technical success of client integrations, from pre-sales feasibility to production go-live, ensuring fast activation and long-term integration stability.
Strong experience working with REST APIs, including authentication, webhooks, error handling, and data modeling.
Prior exposure to complex system integrations, preferably in e-commerce platforms (e.g., VTEX) or ERPs.
Comfortable working with SQL to investigate integration behavior, validate data flows, and support issue triage using BI tools such as Hex or equivalent.
Able to use monitoring and logging tools (e.g., Kibana or equivalent) to identify, diagnose, and communicate production integration issues.
Able to produce clear, concise, and structured technical documentation for external partners and internal teams.
Organized, proactive, and reliable in driving integrations forward across multiple stakeholders.
Curious about customer contexts and constraints, while able to design pragmatic, repeatable integration solutions rather than one-off custom builds.
Prioritizes customer success while balancing platform scalability, reliability, and long-term architectural constraints.
Operates with high autonomy and ownership, demonstrating strong prioritization, self-direction, and accountability while executing against ambitious targets.
Technical pre-sales validation: Lead technical pre-sales by validating feasibility, defining integration scope, and identifying risks before commercial commitment.
Integration delivery and go-live readiness: Support sellers through implementation and testing, and act as the technical authority to approve or block go-live based on readiness criteria.
Post-go-live integration reliability: Ensure the ongoing health of live integrations by owning issue triage, resolution, or escalation within 24 business hours.
Feedback loop to Product and Engineering: Translate integration learnings into actionable feedback to improve platform reliability, scalability, and integration speed.
Align technical decisions with commercial outcomes: Partner closely with Sales and Account Managers to ensure integrations support activation, retention, and GMV growth.
Customer-facing engagement: Frequently travel to customer sites across Brazil to support integrations, technical alignment, and relationship building.
