Embedded Systems Engineering
Our embedded systems engineering services design, build, and certify firmware and hardware-software systems that connect your device to sensors, networks, and the cloud. Everything is engineered for the power and timing budget it'll actually carry, whether as a standalone device or as part of a larger connected-product build.

What We Build
Embedded systems engineering services, built around your device's real constraints
These are the embedded software development services we run, either standalone or folded into a bigger connected-device build, depending on how much of the hardware is already locked in. Most engagements start with the first two and add the rest as the architecture firms up.
Firmware & Embedded Software Development
Bare-metal and RTOS-based firmware, written against your device's real timing and memory budget instead of a generic reference implementation.
Hardware-Software Co-Design
Firmware and component selection happen together during architecture, so a chip or sensor choice doesn't lock the firmware into a rewrite later.
IoT & Edge Connectivity
BLE, Wi-Fi, LoRa, or cellular connectivity scoped to the device's power budget and data volume, with edge processing where round-tripping to the cloud is too slow.
Low-Power & Real-Time Systems
Power profiling and timing analysis built into development, so battery life and response time are measured, not estimated.
Testing & Field Deployment
Thermal, power, and interference testing run under real operating conditions before certification submission, because bench testing alone won't catch what real conditions will.
Continuous Improvement & Scaling
Optimize and scale the product using real-time feedback and market insights gathered after launch.
HOW WE WORK
Our embedded systems engineering process
A device's timing budget and certification path get locked before firmware work starts, so they're verified in testing rather than discovered along the way. Four phases, start to finish.
Requirement Analysis & Architecture Design
The timing budget, power budget, and hardware interfaces get defined against the device's actual operating conditions rather than a reference board. We select the microcontroller, RTOS, and connectivity approach here, before firmware work starts.
DELIVERABLES
- Documented system architecture covering every major component
- Hardware interface and pin-mapping specification
- RTOS or bare-metal decision with supporting rationale
- Power and timing budget, clearly broken down
- Timeline and cost estimate for the build
Certification & Compliance
Certification planned at architecture stage, not before shipping
A device that fails certification after it's built doesn't get a quick fix. It gets a rushed redesign of whatever the certification body flagged. That's why the applicable standards get identified during architecture, before a schematic is finalized, rather than during a submission review.
01
FCC & CE
Required for any device that transmits: FCC for the US, CE for the EU. Scoped early because antenna placement and shielding decisions affect physical layout.
02
IEC 62304
Medical device software lifecycle standard. Documentation and traceability requirements shape how firmware gets structured and tested, not just how it gets written up afterward.
03
IEC 61508
Functional safety for devices where a failure has physical consequences (industrial, automotive). That drives redundancy and fail-safe design decisions at the architecture stage.
04
Typical timeline:
Certification testing itself usually adds 4-8 weeks once hardware is stable. The bigger risk isn't the testing. It's a late-discovered requirement forcing a hardware respin, which is exactly what early scoping is meant to prevent.
Our Methodology
Timing and power budgets are physics, not preferences
You can negotiate a feature scope. You can't negotiate how long a battery lasts on a fixed power budget, or how fast a sensor read has to complete before the next control loop tick. Four things stay non-negotiable on every build.
Real-Time Constraints Modeled Early
Timing budgets get defined during architecture against actual operating conditions, so they're verified in testing rather than discovered under load.
Hardware-Software Co-Design, Not Sequential Handoff
Firmware and hardware selection happen together, so a component choice doesn't lock the firmware into a rewrite six weeks in.
Certification Planned From Day One
Regulatory standards get scoped during design, so they shape architecture decisions instead of blocking a launch date.
Field-Tested, Not Just Bench-Tested
Thermal, power, and interference testing happen under real operating conditions before certification submission, because a clean development board alone won't reveal what real-world conditions will.
Embedded Engineering Practice
Firmware that survives a dev board vs. firmware that survives the field
Response times that look fine at your desk can fall apart at operating temperature, and a battery-life number measured at idle rarely holds up under real duty cycles.
Here's where that gap gets closed.
Firmware Architecture
Modular firmware structured around the device's actual peripherals and update path, so a new sensor or connectivity module doesn't require a rewrite.
Security by Design
Secure boot, encrypted communication, and key management get scoped during architecture planning, so they don't become a pre-certification checklist item added at the last minute.
Field Support
Diagnostics and logging are built into the firmware from the start, so a field failure report includes enough data to reproduce it.
Power Management
Sleep modes, duty cycling, and power profiling built in during development, so battery-life numbers reflect real usage patterns rather than idle bench readings.
Code Quality Standards
Firmware is peer-reviewed, statically analyzed, and tested against real hardware as it's written, so debugging a field failure doesn't mean debugging blind.
Technology Stack
Technologies we build embedded systems with
We're not tied to one microcontroller family or RTOS. Hardware, firmware, and connectivity choices come out of what the device needs to do and the power and timing budget it has to work within.
C / C++ / Rust: Firmware languages
C/C++ for established toolchains and driver support, with Rust used where memory safety matters for long-lived deployed devices.
C / C++ / RustBLE / Wi-Fi / LoRa / Cellular
Connectivity scoped to range, power budget, and data volume.

RTOS choice scoped to the device's complexity and timing requirements.
FreeRTOS / Zephyr / Bare-metalAWS IoT / Azure IoT
Cloud backend services for device fleets that need remote monitoring, OTA updates, or data aggregation.

The Embedded Systems Problem
Why embedded projects run over budget and miss certification
A hardware constraint that should have been modeled at the architecture stage almost always shows up mid-build instead, once it's expensive to fix. Three ways that happens most often:
Hardware-Software Handoff Gaps
Firmware gets written against a spec sheet instead of the actual component, so integration reveals timing or power mismatches that force a redesign late.
Certification Discovered Too Late
Regulatory requirements get treated as a pre-launch checklist item instead of an architecture input, so a device fails certification and the fix requires touching firmware that was already considered done.
Power and Performance Trade-offs Ignored Until Prototype
A feature set gets locked before anyone checks whether the power budget actually supports it, so engineering either cuts features or blows the battery-life target.
Why Us
What makes Apptware an embedded systems engineering partner
Plenty of firmware works fine at your desk. Whether it survives shipping to the field gets decided in the first two weeks, before any firmware gets written.
01
Architecture Scoped Before a Line of Firmware
We define the timing budget, power budget, and certification path upfront: what gets built, how long it takes, and what a device can be relied on to do.
02
Hardware-Software Co-Design From Day One
Firmware and hardware decisions happen together, not handed off sequentially, so a component choice doesn't force a firmware rewrite mid-project.
03
Tested Under Real Operating Conditions
Power, thermal, and interference testing run against real conditions instead of just a clean dev board that passes in the lab and fails in the field.
04
Support After Certification
A certified device still needs field monitoring, an OTA update path, and a plan for the next hardware revision.
Apptware Solutions' work helped the client improve their time-to-market. The team retained all core resources throughout the contract. Apptware Solutions assigned a project manager to oversee the tasks and timelines. The team was proactive in communicating and responding to the client.
