The role combines complex troubleshooting, incident management, system analysis, and platform reliability improvements.
You will investigate transaction-level behavior across high-volume, real-time distributed systems and identify root causes.
You will also contribute to automation, internal tooling, and AI-driven solutions that make support operations faster and more effective.
As a technical bridge between clients and engineering teams, your work will directly influence resolution speed, service quality, and platform stability.
This is a fully remote opportunity for an experienced engineer who enjoys solving complex technical problems and driving continuous improvement.

• Provide advanced technical support for payment and authorization flows, including transaction processing, integrations, and card lifecycle events.
• Investigate complex technical issues and incidents, partnering with Engineering and Technical Account Management teams to determine root causes and validate system behavior.
• Contribute technical expertise during high-severity incidents and escalations, helping drive timely and effective resolution.
• Analyze logs, metrics, transaction data, and system behavior to identify anomalies, patterns, and underlying technical issues.
• Assess the potential impact of platform releases, configuration changes, and operational updates.
• Collaborate with internal teams to clearly communicate technical findings, customer impact, investigation status, and recommended actions.
• Develop internal tools, scripts, and automation that improve troubleshooting, diagnostics, and operational efficiency.
• Explore and apply AI-driven approaches, including agents and automation, to accelerate investigations and reduce repetitive manual work.
• Share technical knowledge across client-facing and internal teams and contribute to documentation and external technical narratives.
• Escalate complex situations with appropriate context, evidence, and technical analysis to ensure effective cross-functional resolution.

• Bachelor’s degree in Computer Science, Engineering, or a related technical discipline, or equivalent practical experience.
• At least 5 years of relevant professional experience with a bachelor’s degree, 2+ years with an advanced degree, or 8+ years of relevant experience without an advanced degree.
• Proven experience with payment processing, authorization flows, or card lifecycle systems, ideally within banking, fintech, payment networks, or other transaction-intensive environments.

• Experience working with high-volume, real-time transactional systems and performing transaction-level debugging and analysis.
• Solid background in technical support, Site Reliability Engineering (SRE), backend engineering, or similar roles involving distributed systems.
• Hands-on experience troubleshooting APIs, integrations, and message-based systems across multiple system boundaries.
• Demonstrated experience managing or supporting critical incidents, performing root cause analysis, and remaining effective under pressure.
• Strong ability to interpret logs, metrics, and transaction data and translate findings into actionable technical solutions.
• Experience collaborating directly with engineering teams to investigate issues, validate system behavior, and provide actionable feedback.
• Familiarity with scripting, automation, or internal tool development; experience applying AI-based approaches to technical support is a strong advantage.
• Excellent analytical, communication, problem-solving, and collaboration skills, with the ability to explain complex technical topics clearly.

• Fully remote position based in Brazil.
• Opportunity to work on high-volume, real-time payment and authorization systems with significant technical complexity.
• Exposure to distributed systems, enterprise payment processing, APIs, integrations, automation, and AI-driven operational tooling.
• Opportunity to collaborate closely with engineering and technical account teams on complex production challenges.
• Scope to improve operational efficiency through automation, diagnostics, and internal technology solutions.
• Senior-level opportunity to influence technical support practices, platform reliability, and incident-resolution processes.
• Work environment focused on continuous improvement, technical problem-solving, and knowledge sharing.
• Full-time employment opportunity with a global technology and payments organization.
