My background in SIM and eSIM engineering, profile lifecycle management, remote provisioning, and interoperability testing aligns closely with the need to deliver reliable SGP.22 and SGP.32 products. I would bring a structured approach to translating requirements into technical specifications, building GSMA-aligned validation strategies, and investigating issues across SIM, device, and network layers. I am also comfortable coordinating with vendors and internal stakeholders to define acceptance criteria, document certification status, and support confident production go/no-go decisions. I would welcome the opportunity to help emnify strengthen the quality, certification readiness, and scalability of its Consumer eSIM and IoT eUICC portfolio. Copy Sample interview questionsDescribe how you would build a validation strategy for a new SGP.22 eSIM profile before production rollout.I would begin by mapping product requirements to applicable GSMA specifications and define traceable acceptance criteria. I would then create a test matrix covering profile installation, download, enablement, disablement, deletion, error handling, security behavior, device compatibility, and network scenarios. The strategy would combine SAIP/BAP-aligned lab testing with real-device and real-network interoperability testing, and would conclude with documented risks, defect status, and production go/no-go criteria. How would you investigate an eSIM activation failure that occurs only on selected devices and mobile networks? I would first collect reproducible evidence, including device models, OS versions, profile logs, provisioning-platform traces, network signaling, and failure timestamps. I would isolate whether the issue is in the profile, LPA/device implementation, SM-DP+ or eIM workflow, network configuration, or an interaction between components. After identifying the likely cause, I would coordinate a fix with the responsible vendor or internal team, validate it across affected combinations, and document the root cause and regression coverage. What is your experience with GSMA artefacts such as SAIP and BAP, and how do you use them in practice? I use GSMA artefacts as structured inputs for interpreting compliance requirements and creating test coverage. In practice, I translate relevant requirements into test cases, expected results, evidence requirements, and traceability records. This makes certification preparation more repeatable and helps distinguish specification compliance issues from implementation-specific interoperability defects. How would you define acceptance criteria for an external SIM/eUICC vendor or remote provisioning platform? I would define measurable criteria across standards compliance, supported profile capabilities, lifecycle behavior, security, performance, observability, interoperability, defect severity thresholds, and documentation deliverables. Criteria should specify the required device and network test matrix, test evidence, escalation paths, and responsibilities for resolving failures. Before production, I would ensure that all critical scenarios pass and that any remaining risks have clear owners and mitigation plans. How do you communicate complex technical certification or interoperability issues to product, support, and customer-facing teams? I tailor the detail to the audience while preserving accuracy. For non-engineering stakeholders, I summarize customer impact, affected scope, severity, decision needed, workaround, and expected resolution timeline; for engineering teams, I provide logs, reproduction steps, technical hypotheses, and root-cause evidence. I maintain clear status reports so stakeholders can make informed rollout and support decisions. 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.
