Operating at the forefront of aerospace and space, cybersecurity and digital identity, we’re driven by a mission to build a future we can all trust.

In Singapore, Thales has been a trusted partner since 1973, originally focused on aerospace activities in the Asia-Pacific region. With 2,000 employees across three local sites, we deliver cutting-edge solutions across aerospace (including air traffic management), defence and security, and digital identity and cybersecurity sectors. Together, we’re shaping the future by enabling customers to make pivotal decisions that safeguard communities and power progress.

Thales Engineering Competence Centre (ECC) is a well established R&D and engineering centre serving major customers worldwide in Digital Identity and Security domains ranging from mobile connectivity, IoT, banking & payment to government solutions.
 

The Test Architect will lead the evolution of testing within the eSIM/eSE development teams, driving a shift from manual testing to a robust, efficient, and scalable automation‑first framework. The role has a strong focus on Android phone-side integration, mobile/embedded test benches, and the software layer that interacts with eSIM/eSE components.
 

This is a technical architecture role requiring the candidate to design, implement, integrate, debug, and demonstrate working device-based automation flows, not only define strategy or documentation. A key responsibility is to ensure a shareable, reusable test ecosystem that serves internal R&D (IVVQ), eTC (embedded Technical Consultants), and FAE (Field Application Engineers) teams supporting customer programs.

Responsibilities:

• Test Bench & Environment Analysis: Understand the current manual test setup, scripts, test flows, data, devices, simulators, HIL/lab infrastructure, backend/simulator services, and product firmware for Thales eSIM/eSE products
• Mobile / Embedded Test Framework Design: Architect and implement a modular automation framework (e.g., Robot Framework/PyTest/JUnit or equivalent) with reusable libraries, fixtures, data, device control, simulator/backend integration, and reporting
• Hands-on Implementation & Integration: Personally implement PoCs and reference flows, including Android device setup, ADB/logcat usage, device provisioning, automation scripts, log collection, simulator/backend integration, and Jenkins/CI execution
• Android Platform & Device Debugging: Support failure analysis across Android phone-side software, system/privileged services, platform or vendor/device layers, backend/simulator, eSIM/eSE firmware, hardware/lab setup, and test scripts.
• Tool & Framework Assessment: Evaluate and recommend practical tools, frameworks, simulators, and lab automation approaches based on capability, maintainability, integration effort, cost, and licensing.
• Process, Quality & Compliance: Introduce shift-left, risk-based testing, automated regression/smoke suites, traceability (requirements -> tests -> defects), quality gates, and audit-ready evidence for applicable GSMA, GlobalPlatform/OMAPI, ISO smart card, and Common Criteria expectations
• Adoption & Reporting: Create playbooks, templates, training, and contribution guidelines; mentor engineers; define KPIs/SLIs such as automation coverage, pass rate, flake rate, MTTD/MTTR, escaped defects, cycle time, and bench utilization

Requirements:

• Degree in Electrical/Electronics/Computer/Software Engineering, or related fields
• Minimum 5 years of experience in software/hardware testing for embedded, mobile, telecom, smart card, secure-element, or device-integrated products, with at least 3 years in test architecture, test automation leadership, or senior technical ownership of test frameworks/benches.
• Able to translate test strategy into working scripts, reusable libraries, device-bench flows, CI jobs, and troubleshooting playbooks
• Capability in C/C++ and at least one of Python, Java, or Kotlin; able to read, debug, and modify test-bench, integration, or product-adjacent code when needed
• Experience with at least one major framework such as Robot Framework, PyTest, JUnit/TestNG, or similar.
• Jenkins pipelines, Git workflows (PR, code review), artifact management (Nexus/Artifactory or equivalent), and practical integration of automated tests into engineering workflow
• Experience with mobile/embedded device testing, REST/gRPC or equivalent APIs, protocol/service mocking, logs/traces analysis, test data management, and failure triage across multiple system layers
• Practical experience integrating, testing, or debugging Android/mobile devices at system or platform level, including ADB/logcat, system/app logs, device provisioning, and failure analysis across phone software, backend/simulator, firmware, hardware/lab setup, and test scripts.
• Exposure to one or more of AOSP-based development/debugging, Android CTS/VTS-style validation, Android HAL/VINTF concepts, vendor/device bring-up, Android telephony/connectivity, Secure Element/NFC, or similar embedded-mobile integration layers.
• Experience in at least one relevant area such as eSIM/eUICC, eSE/Secure Element, UICC/SIM, NFC, smart card, Android telephony, mobile security, telecom device integration, or embedded product validation
