Careers
Senior Embedded Software Engineer – Defence System
We deliver innovative solutions that drive business transformation by streamlining operations, accelerating growth, and ensuring long-term success. From AI and cloud services to cybersecurity and custom application development, Tekbay Digital empowers your business to innovate and thrive in a constantly evolving digital landscape. We manage, optimize, and future-proof your IT infrastructure to help you stay ahead of the curve.
Job Description
You will be the critical bridge between hardware and software, responsible for ingesting high-throughput data from sensors (SDR receivers, radar modules, spectrum analyzers, cameras) into ruggedized Single Board Computers (SBCs), processing it using multi-threaded and multi-core architectures with hardware accelerators, and pushing processed outputs to external systems via both open-standard and proprietary communication protocols.
This role demands deep expertise in low-level C/C++ systems programming, real-time data pipeline design, hardware peripheral integration, and performance optimization on resource-constrained embedded platforms used in mission-critical defence applications.
Roles & Responsibilities
As a Senior Embedded Software Engineer – Defence System, your responsibilities would typically be to:
- Design and develop high-performance C/C++ applications on ruggedized SBC platforms (e.g., COM Express, VPX/VME, SMARC, custom MIL-grade boards) running Linux and/or RTOS environments.
- Architect and implement multi-threaded, multi-core data processing pipelines that ingest high-bandwidth sensor data (USB 3.0/3.1 at 5–10 Gbps, PCIe, Ethernet, serial interfaces) from SDR receivers, radar front-ends, spectrum analyzers (such as Aaronia SPECTRAN V6), and camera feeds.
- Integrate and orchestrate hardware accelerators for parallel compute workloads — including but not limited to NVIDIA Jetson (CUDA/TensorRT), Intel Movidius/OpenVINO, Hailo AI processors, Xilinx/AMD Zynq FPGAs, TI C66x/C71x DSP platforms, and other vendor-specific acceleration hardware — selecting the right accelerator based on latency, throughput, power, and thermal constraints.
- Develop device drivers, kernel modules, and Board Support Packages (BSPs) to interface SBC platforms with peripheral hardware including SDRs, radar modules, GPIO, SPI, I2C, UART, and high-speed USB endpoints.
- Build efficient data pipelines that process temporal/time-series data streams (IQ samples, radar returns, spectral data, video frames) with real-time constraints, applying techniques such as ring buffers, lock-free queues, DMA transfers, zero-copy I/O, and scatter-gather operations.
- Push processed data to external systems (command & control consoles, HPC clusters, recording servers, display systems) using open-standard protocols (DDS/RTPS, MQTT, ZeroMQ, gRPC, REST, VITA 49 Radio Transport) and proprietary/military communication standards (MIL-STD-1553, STANAG, Link 16).
- Implement and adhere to defence interoperability standards including OpenVPX (VITA 65), SOSA (Sensor Open Systems Architecture), CMOSS, and GVA/NGVA where applicable.
- Optimize CPU/memory/IO utilization through profiling, NUMA-aware allocation, CPU pinning, real-time scheduling (PREEMPT_RT, Xenomai), cache optimization, and interrupt affinity tuning for deterministic, predictable performance under sustained loads.
- Collaborate closely with RF engineers, FPGA teams, and systems integration engineers at the site to ensure seamless hardware-software co-design across the full signal chain from antenna to display.
- Maintain comprehensive technical documentation including Interface Control Documents (ICDs), Software Design Descriptions (SDDs), and API specifications compliant with defence documentation standards (JSS 55555, MIL-STD-498).
Job Requirements
Required Qualifications and Skills
- 8–10 years of professional experience in embedded C/C++ software development for SBC, COM, or ruggedized computing platforms in defence, aerospace, or high-reliability domains.
- Deep expertise in multi-threaded and multi-core programming: POSIX threads, thread pools, synchronization primitives, lock-free data structures, work-stealing patterns, and parallel processing on multi-core SoCs.
- Proven experience integrating at least two categories of hardware accelerators (GPU, VPU, FPGA, DSP) into data processing pipelines with heterogeneous compute scheduling.
- Strong Linux systems programming: kernel module development, device driver writing, BSP customization, cross-compilation toolchains (Yocto/Buildroot), and real-time kernel configuration.
- Hands-on experience with high-speed data interfaces: USB 3.0+ (bulk/isochronous transfers), PCIe, GigE/10GbE, and serial protocols (SPI, I2C, UART, RS-422/485).
- Experience implementing or consuming open-standard middleware and protocols (DDS, MQTT, ZeroMQ, gRPC, VITA 49) and understanding of proprietary defence communication standards.
- Working knowledge of signal-domain data types: IQ samples, radar return processing, spectral data formats, and video frame pipelines.
- Proficiency with debugging and profiling tools: GDB, Valgrind, perf, ftrace, LTTng, and hardware-level debugging with logic analyzers and oscilloscopes.
- Strong understanding of defence computing and environmental standards: OpenVPX, SOSA, MIL-STD-810G (environmental), MIL-STD-461G (EMI/EMC).
Preferred Qualifications
- Experience with Software Defined Radio (SDR) frameworks: GNU Radio, SoapySDR, or vendor SDKs from Ettus/NI, Analog Devices, or Aaronia.
- Familiarity with FPGA co-processing workflows (Vivado/Vitis, Intel Quartus) and hardware-software partitioning decisions for heterogeneous architectures.
- Knowledge of proprietary military communication protocols: MIL-STD-1553, STANAG 4586/5516, Link 16/22.
- Experience with RTOS platforms: VxWorks, QNX, INTEGRITY, or RT-Linux (PREEMPT_RT, Xenomai).
- Prior work in the Indian defence ecosystem with DRDO, BEL, HAL, or defence PSU projects.
- Familiarity with radar signal processing concepts: pulse compression, Doppler filtering, CFAR detection, and waveform generation.
- Experience with container-based deployment on embedded/edge platforms (Docker on ARM, Balena, K3s).
Education
- B.E./B.Tech in Electronics, Computer Science, Electrical Engineering, or related field (required).
- M.Tech/M.S. in Embedded Systems, Signal Processing, or Computer Engineering (preferred).
