- We are looking for a Senior Embedded / Firmware Engineer to design and build a platform-independent SDK for reading and verifying digital identity credentials across multiple hardware platforms. - The SDK will support technologies such as NFC, BLE, cryptographic authentication, secure communications, certificate validation, and digital credential verification while maintaining portability across embedded systems and Linux-based environments. - This is a product-focused engineering role where API design, portability, documentation, testing, and long-term maintainability are as important as implementation. - The Role You will be responsible for architecting and developing a reusable embedded SDK that can: - Read and verify digital identity credentials - Establish secure encrypted sessions - Support NFC and BLE communication - Perform cryptographic verification and certificate validation - Operate across multiple embedded and Linux platforms - Provide clean APIs and hardware abstraction layers (HALs) - Support third-party integrations Key Responsibilities SDK Architecture & Development - Design public SDK APIs and interfaces - Define abstraction layers for: - Cryptography - Secure key storage / HSMs - NFC communication - BLE communication - OS and timing services - Implement secure communication and credential verification workflows - Build modular, maintainable, and well-tested code Platform Support - Support embedded RTOS environments and Linux platforms - Develop portable code across multiple architectures and toolchains - Maintain cross-platform build systems and CI/CD pipelines - Ensure API and ABI stability across releases Documentation & Developer Experience - Create API documentation and integration guides - Develop test harnesses and validation tools - Support external developers integrating the SDK Required Skills - 2+ years of skilled Embedded C development - Experience building reusable SDKs or libraries consumed by external teams - Strong understanding of: - Embedded systems - RTOS environments - Memory-constrained development - Cross-compilation and toolchains - Experience with: - NFC protocols - BLE communication - Cryptography (ECDSA, ECDH, AES-GCM, HKDF, HMAC) - CMake-based build systems - Strong testing and debugging skills Preferred Skills - Digital identity or credential verification systems - CBOR / COSE - Secure elements and hardware security modules - NFC reader technologies - Python integration experience - Certificate validation and PKI concepts - Embedded Linux development What We''re Looking For We''re looking for someone who can take ownership of a complex SDK product, make sound architectural decisions, and deliver high-quality, maintainable software that can be used across multiple hardware platforms and by external engineering teams. - Experience building commercial SDKs, libraries, middleware, or protocol stacks is highly valued. - Location: Delhi NCR,Bangalore,Chennai,Pune,Kolkata,Ahmedabad,Mumbai,Hyderabad .
Here's how to pick the right one and stand out in your application.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
