We’re looking for a Technical Product Manager to own the technical implementation and reliability of our eSIM and telecom services.

Working closely with Product, Telecom, Engineering, QA, and Support, you’ll turn vendor capabilities, coverage, plan rules, and provisioning requirements into reliable product solutions — from integrations and technical requirements to troubleshooting and post-release improvements.

📝Responsibilities

• Own the technical side of the eSIM lifecycle: provisioning, installation, activation, network registration, usage, top-ups, and edge cases.

• Work with ICCID, IMSI, EID, MSISDN, APN, SM-DP+, activation codes, plan mapping, and provisioning statuses.

• Launch and improve telco/vendor integrations involving APIs, webhooks, status mapping, error handling, logging, and monitoring.

• Investigate production issues with Support, Engineering, and Telecom and turn recurring problems into systematic improvements.

• 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.

• Experience with Jira, Confluence, and/or Notion.

🎁What We Offer

• Fully remote work with an international team.

• Direct impact on the technical quality and reliability of a global eSIM product.

• Ownership of complex eSIM and telecom integrations from requirements through production.

• Close collaboration with Product, Telecom, Engineering, QA, and Support.

• Hands-on work with real-world roaming, provisioning, and connectivity challenges.

• Plenty of room to influence both product development and technical processes.
