•Prepare clear requirements, acceptance criteria, and test scenarios for Engineering and QA.
•Own technical changes through release and post-release validation while keeping documentation and debug flows up to date.
Requirements
•Hands-on experience in telecom, eSIM, connectivity, roaming, MVNO/MVNE/MNO, or carrier integrations.
•Strong understanding of eSIM activation and provisioning flows, including ICCID, IMSI, EID, SM-DP+, APN, and network registration.
•Understanding of Apple/iOS eSIM provisioning, device compatibility, carrier/profile settings, and common installation and activation issues.
•Experience with telco/vendor APIs, webhooks, logs, errors, and production troubleshooting.
•Ability to translate complex technical issues into clear product and engineering requirements.
