Principal software engineer

Experience: 10+ years Location: Noida Employment Type: Full‑time Team: Platform / Systems / Security Engineering Role Summary We’re looking for a Principal Software Engineer who combines deep systems expertise with security-first design. You will lead architecture and development across Linux kernel, boot loader, and user‑space middleware, building secure, reliable, and performant platforms that power our next-generation [products/platforms]. You’ll set technical direction, elevate engineering standards, mentor senior engineers, and partner with cross-functional stakeholders to deliver high-impact outcomes. What You’ll Do Design and implement security features in boot loader complementing secure boot, measured boot, and chain of trust. Design and implement security features in Linux kernel features (e.g., device drivers, filesystems, networking stack, security modules). Build and optimize user‑space middleware (e.g., IPC frameworks, OpenSSL, DPDK) leveraging Userspace drivers. Implement and integrate security protocols (e.g., TLS 1.3, DTLS, IPsec, SSH,) and hardware-backed key management. Drive threat modeling, secure design reviews, and code audits, ensuring compliance with best practices (e.g., ASLR, stack canaries, SELinux/AppArmor policies). Lead performance and reliability engineering including profiling, tracing (ftrace, eBPF, perf), memory safety, and resource efficiency. Define platform CI/CD for low-level software (artifact signing, SBOMs, reproducible builds, Yocto/Buildroot/DEB/RPM pipelines). Mentor and grow engineers, guide technical roadmaps, and make pragmatic build/buy/OSS leverage decisions. Collaborate with Design team, IP team, DevOps, product, and QA to meet functional, performance, and certification goals. Qualifications (Required) 10+ years of professional experience in systems/embedded/platform engineering, including technical leadership at team or org scale. Expert in C/C++ for systems-level development; nice to have proficiency in Rust for memory‑safe components. Demonstrated depth in Linux kernel internals (at least two areas): drivers, MM, scheduler, net, filesystems, security modules (LSMs), eBPF. Hands-on boot loader development and customization (U‑Boot, GRUB, secure boot flows, measured boot, boot-time diagnostics). Strong knowledge of security protocols and cryptography (TLS/IPsec, X.509/PKI, key exchange, HSM/TPM, secure storage, attestation). Experience building user‑space middleware (IPC, service management with systemd, observability/logging, configuration frameworks). Proficiency with Linux build systems and distributions for embedded/platform (Yocto/OpenEmbedded, Buildroot) or enterprise (Deb/RPM). Proven ownership of architecture/design documents, RFCs, and shipping production-quality platform software. Debugging mastery using kernel/user tools (kgdb, crash, perf, ftrace, strace, gdb, BPF tools) on real hardware/virtualized targets. Nice to Have Trusted execution & firmware: ARM TrustZone, OP‑TEE, Intel SGX/TDX, AMD SEV, TF‑A, UEFI, ACPI/Device Tree. Virtualization & containers: KVM/QEMU, Kata Containers, cgroups, namespaces; container security (seccomp, SELinux/AppArmor). Networking & storage: DPDK, SR-IOV, NVMe, RDMA, io_uring; high‑throughput low‑latency pipeline design. Safety/security certifications: FIPS 140‑3 validation, Common Criteria, ISO 27001/21434, AUTOSAR, IEC 62443. Secure software supply chain: artifact signing, SBOM (SPDX/CycloneDX), SLSA levels, reproducible builds. Scripting/automation: Python, Bash; Bazel/CMake/Meson; advanced CI (GitHub Actions, GitLab, Jenkins, Buildkite). Observability: eBPF tracing, LTTng, SystemTap, ETW analogs; production telemetry & fleet operations. HW familiarity: SoC bring‑up, board support packages (BSP), JTAG, oscilloscopes, power/thermal profiling. More information about NXP in India... #LI-2734 NXP Semiconductors N.V.
