In this role, you will bridge the gap between low-level hardware interactions, high-level architectural design, and strict payment industry compliance.\nOur engineering culture prioritizes safety, deterministic execution, ultra-low latency, and transactional security. You will leverage modern C++17 to build robust, zero-overhead abstractions-completely eliminating legacy, error-prone C patterns. You will own the end-to-end automation pipeline, ensuring software quality via cross-compilation, advanced ISTO -compliant hardware tracing, and secure EMV transaction workflows.\nCore Responsibilities\nØ EMV Protocol Implementation & Compliance: Design, optimize, and maintain EMV Contact (L1/L2) and Contactless kernels. Implement highly secure, zero-allocation APDU parsing pipelines and cryptographic wrappers that comply with strict payment network certifications.\nØ Modern Driver Architecture: Design and maintain peripheral drivers (SPI, I2C, UART, CAN, DMA, NFC/RFID interfaces) utilizing C++17 compile-time design patterns (if constexpr, template polymorphism) to eliminate runtime overhead.\nØ Advanced Trace & Debugging (ISTO): Leverage ISTO standards (e.g., IEEE-ISTO Nexus 5001 Global Embedded Processor Debug Interface) for non-intrusive trace, performance analysis, and root-cause debugging of bare-metal applications without impacting timing behavior.\nØ Resource & Memory Management: Author deterministic, zero-heap applications using custom allocators, placement new, and RAII wrappers to guarantee zero memory leaks and block-free execution during time-critical payment processing.\nØ Firmware Virtualization & Simulation: Build and manage cross-compilation toolchains targeting custom architectures. Set up and run automated test suites inside QEMU / Software-in-the-Loop (SIL) environments for EMV regression testing.\nØ Sanitizer Instrumentation: Instrument code and debug complex runtime issues using memory, thread, and undefined behavior sanitizers (ASan, TSan, UBSan) integrated directly into CI/CD pipelines.\nRequired Technical Skills & Competencies To be successful in this role, you must be able to demonstrate deep expertise in the following areas during our technical assessment:\n1. EMV & Secure Systems Engineering\nØ Demonstrated experience developing embedded software compliant with EMVCo specifications, ISO 7816, or ISO 14443 standards.\nØ Understanding of secure elements, payment cryptography (RSA, DES/3DES, AES), and side-channel attack mitigation in a bare-metal environment.\n2. Advanced C++17 Concepts\nØ Deep understanding of non-owning memory types (std::string_view) and explicit error-handling models without heap usage (std::optional, std::variant) to handle complex payment state machines safely.\nØ Expert utilization of type-safe hardware mapping tools (std::byte) and strict safety enforcements ([[nodiscard]]).\n3. Low-Level Memory & Concurrency Management\nØ Strong knowledge of disabling non-deterministic language features (e.g., building with -fno-exceptions and -fno-rtti) while preserving architectural safety.\nØ Mastery of thread synchronization using lightweight, lock-free hardware atomics (std::atomic) over heavy mutexes to prevent priority inversions during synchronous I/O operations.\n4. Simulation, DevOps, and Tooling\nHands-on experience interpreting complex stack traces, utilizing ISTO tracing protocols, and debugging target-specific binaries running under emulators (QEMU).\nExperience writing and optimizing automated test configurations for CI/CD environments (GitHub Actions, GitLab CI, or Jenkins).\nQualifications\nØ Bachelor’s/Master’s degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field.\nØ 5+ years of experience developing production-grade firmware for bare-metal systems or RTOS environments (e.g., FreeRTOS, Zephyr).\nØ Expert-level proficiency in modern C++ (C++17 or later) and modern CMake build systems using VSCode / Kiro IDE.\nØ Strong familiarity with ARM Cortex-M, RISC-V, or similar modern microprocessor architectures, specifically those featuring advanced secure enclaves/TrustZone.","description_format":"text","description_chars":4395,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["IT Consulting & Digital Transformation","Engineering Services"],"lifecycle":[{"event":"open","at":"2026-11-06T13:25:33Z"}],"visa":[],"liveness":{"score":79,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.879,"p_room":0.9,"age_days":29,"expected_fill_days":46,"reasons":["conf:2","velocity","win:mid","comp:brand"],"computed_at":"2026-11-07T05:47:08Z"},"pay":null,"html_url":"https://alion.io/job/cyient-contractor-software-engineer","json_url":"https://alion.io/job/cyient-contractor-software-engineer.json","meta":{"generated_at":"2026-11-07T16:30:25Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":23304,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-08T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":59344},"rest":"https://alion.io/mcp/rest/get_company?id=59344"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcyient-contractor-software-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fcyient-contractor-software-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fcyient-contractor-software-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/cyient-contractor-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcyient-contractor-software-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3868815}},{"tool":"search_jobs","arguments":{"company":"cyient.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3868815},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
