Support customer integrations from initial setup through successful go-live.

Collaborate with internal engineering, integration, and account management teams to address customer requirements.
Create and maintain technical documentation, troubleshooting guides, and internal runbooks.

Hands-on experience supporting SaaS products.
Strong software troubleshooting and root-cause analysis skills.
Solid knowledge of Linux, HTTP, REST APIs, and proxies.
Practical experience independently debugging network-related issues, including DNS, TCP/IP, routing, connectivity, and TLS/SSL.
Ability to read, understand, and debug code in Python, Go, Java, or a similar programming language.
Experience working with API testing and troubleshooting tools such as Postman and cURL.
Ability to investigate complex technical problems independently and clearly communicate findings.
English B2+, both written and spoken, with the ability to communicate technical information to customers and internal stakeholders.
Strong communication, problem-solving, collaboration, and stakeholder management skills.

Nice to Have:

Experience with Docker and AWS.
Knowledge of payment processing, tokenization, cryptography, or security-related technologies.
Experience supporting API-driven platforms or complex third-party integrations.
