Senior eSIM Engineer - SGP.22 SGP.32 GSMA Specialist in Columbus
Career & Market Insight
This is a highly specialized, senior-level role in a niche but rapidly growing segment of the telecommunications industry. eSIM/eUICC expertise — particularly around GSMA SGP.22 (Consumer eSIM) and SGP.32 (IoT eUICC) — is in short supply globally, giving qualified candidates strong leverage.
Market positioning:
- eSIM engineers with GSMA certification experience command premium salaries. In Germany/Austria/Switzerland, senior specialists in this domain typically earn €70,000–€120,000+ annually, with Swiss-based roles often exceeding this range.
- The IoT eSIM (SGP.32) space is still maturing, making early expertise a strong career differentiator as device volumes scale through 2025–2030.
Skills you will develop:
- Deep GSMA standards mastery (SGP.22, SGP.32, SAIP, BAP) — transferable to any MNO, MVNO, or SIM vendor globally
- Cross-domain debugging (SIM + device + network) — a rare and valued T-shaped skillset
- Vendor and platform management (SMDP+, eIM) — relevant to enterprise IoT and consumer device ecosystems
Green flags: End-to-end ownership, clear technical scope, cross-functional visibility (Product, Support, Customer teams). Watch for: No mention of benefits, team size, or company stage — worth clarifying in the interview to assess growth trajectory and workload expectations. The truncated bullet point in the original posting ("operational models") may indicate an incomplete job description.
Your Role
We are looking for a hands-on UICC/eUICC/eSIM specialist to take ownership of the engineering, interoperability, and certification readiness of our Consumer eSIM (SGP.22) and IoT eUICC (SGP.32) products.
You will operate across the full lifecycle, from profile design and technical specification to validation and production readiness, working at the intersection of SIM technology, devices, and mobile networks. The role is focused on ensuring our eSIM products meet a high bar for quality, reliability, and interoperability before rollout.
Your Impact
- Own the end-to-end engineering and validation of SGP.22 and SGP.32 eSIM products, including profile design reviews and translation of product requirements into technical specifications
- Define and execute certification and validation strategies using GSMA artefacts (e.g. SAIP, BAP), including lab and real-world interoperability testing across devices and networks
- Investigate and resolve complex cross-domain issues (SIM, device, network), providing clear root cause analysis and coordinating fixes with internal teams and external vendors
- Act as the technical point of contact for remote provisioning platforms (SMDP+, eIM) and SIM/eUICC vendors, including defining acceptance criteria and supporting go/no-go decisions for production rollout
- Produce clear technical documentation (test reports, defect analysis, certification status) to enable Product, Support, and Customer-facing teams
Your Skills
- Strong hands-on experience in SIM/eSIM/eUICC engineering, validation, certification, or a closely related technical domain
- Proven experience working with GSMA standards, particularly SGP.22 and SGP.32
- Solid understanding of UICC/eUICC architecture, profile lifecycle, and OTA/provisioning processes
- Experience designing and executing test strategies using certification-style artefacts (e.g. SAIP, BAP or similar)
- Ability to debug complex issues across SIM, device, and network layers and coordinate resolution with multiple stakeholders
