Principal Embedded Systems Engineer

About Us

We are a fast-growing deep-tech startup building next-generation embedded products from the ground up. We move fast, prototype aggressively, and take ideas from whiteboard to production.

If you enjoy solving real-world hardware challenges, writing tight firmware, bringing up boards, and seeing your design go into mass production, you’ll love it here.

Key Responsibilities

• Design and develop embedded hardware systems based on microcontrollers and SoCs
• Develop, test, and optimize embedded firmware in C/C++
• Perform schematic design, component selection, PCB review, and board bring-up
• Develop low-level drivers for peripherals (UART, SPI, I2C, CAN, USB, Ethernet, etc.)
• Debug hardware/firmware issues using oscilloscopes, logic analyzers, and debuggers
• Collaborate with cross-functional teams (mechanical, testing, manufacturing)
• Support product validation, compliance testing, and production release
• Prepare technical documentation and design reports
• Collaborate directly with founders and product teams
• Take products from prototype to manufacturing

You won’t just “contribute.” You’ll own modules and ship products.

Required Skills & Qualifications

• 4–8 years of hands-on experience in embedded systems
• Strong embedded C/C++ skills
• Experience with microprocessors/microcontrollers, SOCs’
• Experience in power supply designs, analog and digital interfaces.
• Experience in schematic design & PCB review
• Strong debugging skills using oscilloscopes, logic analyzers, and JTAG
• Deep understanding of communication protocols (SPI, I2C, UART, CAN, Bluetooth, WiFi, etc.)

You should be comfortable moving between hardware and firmware without hesitation.

Good to Have (But Not Mandatory)

• FPGA development (Verilog/VHDL)
• Experience with Xilinx/Intel FPGA tools
• High-speed digital design exposure
• Embedded Linux experience
• EMI/EMC awareness

Educational Qualification

• B.E./B.Tech/M.E./M.Tech in Electronics, Electrical, and Embedded Systems.

Who Will Thrive Here

• Builders who like solving messy real-world problems
• Engineers who take ownership instead of waiting for instructions
• People who enjoy fast iterations and tight deadlines
• Those who prefer impact over hierarchy

Why Join Us

• Work on cutting-edge embedded products
• High ownership & decision-making power
• Fast learning curve
• Direct impact on product architecture

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).
