Sii develops embedded software and firmware for connected devices, delivering high performance and reliability from design to deployment.
Our embedded engineers support the complete lifecycle – from system architecture and requirement analysis to coding, debugging, and validation. Sii’s experts tailor each solution to your business case and technical constraints, using platform on different embedded architectures: ARM, RISC-V, x86/64, MIPS Our specialists build solutions on bare-metal and RTOS-based systems, Embedded Linux (Yocto) and Android, as well as FPGA emulators and secure elements.
We’ve delivered solutions for:
When latency, determinism and throughput are non-negotiable, Sii focuses on architecture-level design and low-level tuning for QNX, real-time Linux and BSD to deliver predictable timing under constrained CPU, memory, and power budgets. We concentrate on measurable behavior (worst-case latency, jitter, sustained throughput) validated by profiling and long-haul reliability tests.
We implement:
Our engineers design reliable data exchange protocols across wired and wireless interfaces. Whether on a PCB or over kilometres, we enable secure, energy-efficient connectivity for the IoT and beyond. We engineer robust communication stacks with data integrity checks and security layers – so your embedded systems communicate fluently and securely with the outside world.
We support:
To meet unique adaptation demands, we develop custom firmware and offer full software porting services across platforms and architectures.
Our process includes:
From medical tech to automotive, our multidisciplinary teams bring decades of experience and battle-tested know-how across microcontrollers, operating systems, and real-world applications. We’re equipped to scale any R&D vision into a reliable, production-grade device.
We design and develop embedded software for devices that require low power consumption and optimal resource usage. Thanks to Sii’s specialized expertise, clients in wearables, IoT, and edge computing receive reliable, energy-efficient software that delivers stable, fast performance while extending device battery life – all without compromising code quality and maintainability.
Our embedded systems integrate secure boot, encryption, and platform integrity features by default. We follow best practices for secure embedded development and can support you through industry-specific compliance or certification processes (i.e.: DevSecOps frameworks).

Our clients span semiconductor, automotive, healthcare, consumer electronics, smart metering, industrial IoT, and more – wherever customized, power-efficient, and reliable embedded software is mission-critical.
Yes. We implement WiFi, BLE, Zigbee, Z-Wave, and LoRaWAN communication stacks tailored to power-sensitive IoT devices and long-range, low-maintenance deployments.
We use static and dynamic code analysis, continuous integration pipelines, hardware-in-the-loop testing, and peer reviews. Our quality benchmarks span functionality, footprint, power usage, and security. See more about our embedded systems.
We analyze hardware specs, migrate code and drivers, update toolchains, and optimize memory layout and interfaces. Our aim: same function, better fit, without regressions.
