3+ JTAG Jobs in Bangalore (Bengaluru) | JTAG Job openings in Bangalore (Bengaluru)

Job Description:

We are looking for skilled Design for Test (DFT) Engineers with 3–8 years of experience to join our growing team. The ideal candidate should have strong expertise in DFT architecture, implementation, and validation for complex SoCs.

Key Responsibilities:

• Develop and implement DFT architectures (Scan, MBIST, LBIST, Boundary Scan)
• Work on scan insertion, ATPG pattern generation, and fault coverage analysis
• Collaborate with design and verification teams for testability improvements
• Perform DFT verification and debug of test patterns
• Handle silicon bring-up, debug, and yield improvement activities
• Ensure high-quality test coverage and optimize test time

Required Skills:

• Strong hands-on experience in Scan, ATPG, MBIST, LBIST
• Good knowledge of DFT tools like Tessent / Modus / Encounter Test
• Experience in JTAG / Boundary Scan (IEEE 1149.1)
• Understanding of SoC architecture and digital design concepts
• Scripting knowledge in Perl / Python / Tcl
• Experience in debugging silicon issues is a plus

Key Responsibilities

1. Kernel Lifecycle & Maintenance

Upstream Alignment: Lead the strategy for upgrading enterprise kernels (e.g., migrating from LTS 5.15 to 6.6) while maintaining binary compatibility where required.

Patch Porting: Expertly port functional and performance patches between disparate kernel versions, resolving complex code conflicts and API changes.

CVE Mitigation: Monitor the Linux Kernel Mailing List (LKML) and security advisories to identify and backport CVE patches from upstream to production environments.

2. Deep-Dive Debugging & Stability

Panic Analysis: Act as the final escalation point for Kernel Panics and "Oops" messages. Utilize kdump, crash, and gdb to perform post-mortem analysis of vmcores.

Boot-Time Resolution: Debug critical failures during the early boot process (UEFI handoff, initramfs, and early kernel init) where standard logging is unavailable.

Performance Tuning: Use ebpf, ftrace, and perf to identify bottlenecks in memory management, scheduler latency, or I/O throughput.

3. Driver Development & Hardware Integration

Driver Ownership: Design, develop, or maintain at least one Open Source or Proprietary Device Driver (Network, Storage, GPU, or Character devices).

Hardware Abstraction: Interface directly with hardware registers, managing DMA mappings, and optimizing interrupt handling (MSI-X, Threaded IRQs).

Out-of-Tree Management: Maintain driver compatibility across kernel updates using DKMS or similar frameworks.

4. Infrastructure & Automation

Registry Management: Oversee the distribution of custom kernel builds and modules via GitLab Container/Package Registries.

CI/CD for Kernel: Build automated testing pipelines (Hardware-in-the-loop) to validate kernel stability before enterprise-wide deployment.

Required Technical Skills:

Languages: Mastery of C/C++ Programming (C is preferred)

Kernel Internals: Deep understanding of VFS, Memory Management (MMU/Paging), Process Scheduling, and Networking Stacks.

Debugging Tools: Expert-level use of kprobes, trace-cmd, valgrind, and hardware-level debuggers (JTAG/Serial Console).

Build Systems: Proficiency with Kbuild, Makefiles, and building RPM/Debian packages for kernel distribution.

Security: Hands-on experience with SELinux/AppArmor policy development and kernel hardening (FIPS, KSPP).
