Analytics Engineering Manager

Engineer

• Design and validate eSIM Electrical Profiles (MVNO/Roaming) following GSMA SGP.22 standards.
• Rigorously test the Local Profile Assistant (LPA) behavior on the latest flagships (iPhone 16, Samsung S24, Pixel 9) to ensure flawless Remote SIM Provisioning.
• Plan and execute Over-the-Air (OTA) campaigns to update eUICC file systems and steering logic for devices already deployed globally.
• Use tools like COMPRION or UL SIMtester to analyze APDU logs and debug communication failures in Remote File Management (RFM).
• Verify Steering of Roaming (SoR) logic on global testbeds, ensuring our users always land on the fastest partner network.
• Minimize profile sizes to guarantee fast downloads over 3G, 4G, and 5G network conditions.

eSIM & Device Engineer – Core Networks

Full-stack Engineer

• You’ll lead the design and growth of our Packet Core (EPC/5GC), ensuring our network scales effortlessly as our global traveler base doubles and triples.
• You’ll be our primary architect for global connectivity, managing roaming coverage through IPX/GRX providers and securing bi-lateral agreements that keep our users online everywhere.
• You’ll dive deep into signaling procedures across 3G, 4G, and 5G NSA. When a connection fails, you’re the expert who decodes the "why" using tools like Wireshark to look under the hood of Diameter and GTP signaling.
• You’ll fine-tune critical network flows—from the moment a user "attaches" to the network to the creation of high-quality voice and data bearers—ensuring every byte is delivered with precision.
• You’ll lead design reviews and manage the "Acceptance Testing" (ATP) phase to ensure our partners deliver to the high standards our users expect.

Senior Engineer, Core Network

Network Engineer

• Design and dimension the Packet Core (EPC/5GC) to ensure scalability for data growth.
• Manage roaming coverage with IPX/GRX providers, roaming sponsors, and direct bi-lateral agreements.
• Define specific network profiles and configurations for HSS/UDM subscribers, including QoS, AMBR, and APN subscriptions.
• Architect the DNS hierarchy for the mobile core, focusing on S-NAPTR records for MME/SGSN to discover PGW/SGW/UPF nodes.
• Plan and implement IP routing strategies, including ASN (Autonomous System Number) management and BGP peering for internet and roaming connectivity.
• Manage Access Point Name configurations for various service types, including IMS, Internet, and IoT.
• Perform deep-dive troubleshooting of signaling procedures across 3G (Iu-PS), 4G (S1-MME, S11, S5/S8), and 5G NSA (EN-DC).
• Apply in-depth understanding of 3GPP standards for 3G, 4G EPC, and 5G NSA mobile data call-flows.
• Analyze and optimize critical flows, specifically Attach/Registration (Authentication vectors, ULR/ULA, Create Session) and Bearer Management (Dedicated bearer creation for VoLTE/QCI 1 and default bearers).
• Utilize protocol analyzers such as Wireshark or Tektronix to decode ASN.1 based messages and Diameter signaling (Gx, Gy, S6a, S5, S8, GTP-C, GTP-U).
• Act as the primary technical interface with core network vendors, system integrators, and partners.
• Lead technical evaluations and design reviews for core network expansions.
• Manage the ATP (Acceptance Testing) phase to ensure vendor deliveries meet operational standards prior to live deployment.

Senior Core Network Engineer

• Design, develop, and validate eSIM Electrical Profiles (MVNO/Roaming) according to GSMA SGP.22 standards.
• Configure file structures ($EF_{ICCID}$, $EF_{IMSI}$, $EF_{PLMN}$, etc.) and ensure correct applet loading.
• Manage the generation and testing of Input Files for Subscription Management platforms (SM-DP+).
• Conduct rigorous testing on the latest iOS and Android flagships (e.g., iPhone 15/16, Samsung S24, Pixel 9) and mid-range devices from global markets (APAC/LATAM/EMEA).
• Validate the Local Profile Assistant (LPA) behavior during the Remote SIM Provisioning (RSP) flow—from QR code scanning to the TLS-secured profile download.
• Plan and execute Over-the-Air (OTA) campaigns to update the eUICC file system ($EF_{PLMN}$, $EF_{IMSI}$) or applet parameters on devices already deployed in the field.
• Use tools like the COMPRION eSIM Tracer or Ul SIMtester to analyze APDU logs and identify failures in Remote File Management (RFM) or Remote Application Management (RAM) over HTTP, or HTTPS (CAT-TP).
• Perform "live" OTA testing using network simulators or global roaming testbeds to verify Steering of Roaming (SoR) updates and ensure the device correctly switches to the preferred partner network.
• Analyze protocol traces (APDU logs) to debug communication issues between the handset and the eUICC.
• Investigate "No Service" or activation failures specific to international roaming steering.
• Optimize profile sizes to ensure fast download speeds over varying network conditions (3G to 5G).
