Embedded Software Engineer (C/C++ · Signal Processing)

About the Role

SiFly is seeking an Embedded Software Engineer with strong C/C++ fundamentals to help build and ship reliable, performance-critical software for real-world systems. In this role, you’ll work on embedded Linux–based platforms and pipeline-style components such as audio, video, or sensor streams, focusing on latency, timing, and robustness.

This position is ideal for a hands-on engineer who enjoys debugging real systems, working close to hardware, and collaborating across disciplines. You don’t need to be a narrow specialist—but you should have solid engineering fundamentals, sound judgment, and the ability to learn quickly in a production environment.

What You’ll Do

• Build and ship production-quality features in C and/or C++ on embedded Linux systems.
• Debug and improve software running under real-world constraints such as latency, CPU usage, memory limits, and I/O bandwidth.
• Design, implement, and maintain pipeline-style components (audio, video, or sensor data), including buffering, timing, synchronization, and observability.
• Write clean, modular, and maintainable code with well-defined APIs and documentation.
• Add appropriate tests and tooling, including unit tests, lightweight integration tests, and development scripts.
• Use profiling, logging, and debugging tools (gdb, system profilers, tracing) to identify and resolve performance and reliability issues.
• Collaborate through code reviews and clear technical communication with cross-functional teams.

What We’re Looking For

• Strong C or C++ skills with real “shipping code” experience in production systems, commercial products, or widely used internal tools.
• Hands-on debugging experience on Linux and/or embedded targets, including effective use of logs, gdb, profiling tools, and systematic root-cause analysis.
• Comfort working on performance-critical systems, with practical experience in profiling, memory ownership and lifetime, data movement, and latency-sensitive design.
• Solid engineering workflow experience, including Git-based development, code review culture, and familiarity with build systems.
• Sufficient electrical engineering / signal processing background to understand and discuss:

-Signals and sampling fundamentals

-Frequency-domain intuition

-Basic filters (low-pass, high-pass, cutoff frequency, noise vs. signal)

-Introductory control systems concepts

Ability to collaborate effectively with other engineers, communicate technical decisions clearly, and maintain clean, well-documented code.

Nice to Have

• Experience with audio pipelines, including capture/playback, buffering, resampling, synchronization, and debugging glitches or dropouts.
• Audio DSP familiarity: EQ and basic filters, dynamics, noise reduction concepts, FFT-based processing, fixed-point vs. floating-point tradeoffs.
• Experience deploying AI models for audio, video, or image processing, including real-time inference constraints and integration challenges.
• Python experience for tooling, experiments, test harnesses, or data analysis.
• Networking fundamentals (TCP/UDP, sockets, latency tuning, MQTT basics).
• Docker or container experience, including image building, runtime configuration, and debugging.
• Embedded Linux experience: cross-compiling, system services, and deployment workflows.
• RTOS familiarity (e.g., FreeRTOS concepts such as tasks, queues, and timing).
• Media pipeline experience (GStreamer is a plus).
• Computer vision background.
