Embedded in connected systems

Firmware is architected with the connected system in mind.

Firmware sits on your critical path, is the most expensive to change, and, in medical devices, carries the highest safety risk. Poor firmware decisions cascade through your entire product.

We architect embedded software with a system-level perspective. Because we work across devices, mobile, cloud, and electronics, we design for the full system and not just the embedded layer.

The Result: Firmware that integrates cleanly with your connected system, scales to production, and supports your regulatory pathway without blocking development.

A group of hands supporting different stages of product development being moved along.

What we solve for

Embedded Development at Every Stage

Whether you’re building from scratch, validating user workflows, looking to accelerate development, or fixing critical production issues, we can help.

WHAT YOU GET

Production-Ready Firmware with Engineering Traceability

We deliver tested, traceable firmware with the build systems, verification evidence, and documentation that regulatory teams require.

An illustrative collage of embedded elements (visuals capturing coding, process documentation, HAL, embedded process, and compliance alignment).

Firmware development requires more than working code. You need to build systems, test infrastructure, traceability matrices, and verification evidence that support regulatory submission and long-term maintainability.

Our deliverables create an auditable trail from requirements through release, essential for products that scale, transfer between teams, or require regulatory approval.

  • Design: Traceable requirements, architecture, and design documentation that integrates with your broader system definition.
  • Development: Version-controlled, reviewed source code developed against requirements and design, with build systems and toolchain configuration for reproducible builds.
  • Verification & Validation Evidence: Requirements verification, risk-based unit and integration testing, plus verification plans, protocols, and reports. 
  • Release: Traceable software artifacts, SBOM, vulnerability analysis, and unresolved anomaly reports.
