01 — CORE PRACTICE

Functional Safety & Cybersecurity Engineering

We build and defend the safety and security case for systems where failure isn't an option — from initial HARA through audit-ready deliverable packages.

HARA & Safety Case Development

Hazard analysis, ASIL determination, and safety case construction under ISO 26262.

TARA & Cybersecurity Management Systems

Threat analysis and CSMS build-out to ISO/SAE 21434 and UN R155/156 for Type Approval.

Software Safety Lifecycle

ISO 26262-6 aligned development process and ASPICE assessment support.

SOTIF Analysis

Performance-limitation and misuse analysis under ISO 21448 for systems with autonomous functions.

Traceability & Audit Support

Requirement-to-deliverable traceability matrices built for third-party assessment.

02 — CORE PRACTICE

Software & Firmware Engineering

The embedded code that runs the hardware — control algorithms, drivers, and the safety-lifecycle discipline behind them, written by the same team that owns the safety case.

Embedded Firmware Development

Bare-metal and RTOS firmware for motor control, power electronics, and sensing platforms.

Real-Time Control Algorithms

Field-oriented motor control, power conversion, and sensor fusion algorithms implemented and validated on target hardware.

Board Support Package & Drivers

Bootloaders, peripheral drivers, and hardware abstraction layers built for a certification-ready codebase.

MISRA C Compliant Development

Coding-standard enforcement and static analysis integrated from the first commit, not retrofitted before an audit.

Unit Test & Structural Coverage

Unit test and MC/DC coverage evidence aligned to ISO 26262-6, produced alongside the code — not after it.

Hardware & Electronics Design (NRE)

Outsourced electronics design engagements for teams that need senior hardware engineering without building an in-house team — schematic capture through prototype bring-up.

Schematic Capture & Component Selection

Architecture definition, part selection, and lifecycle/second-source risk review.

PCB Layout

High-speed digital, mixed-signal, and power layout — stack-up definition, signal integrity, and thermal review.

Prototype Bring-Up & Validation

Bench bring-up, functional test, and root-cause debug on first-article boards.

DFM / DFT Review

Design-for-manufacture and design-for-test review ahead of production release.

EMC Pre-Compliance Design

Layout and filtering decisions made up front to reduce pre-compliance test cycles.

HOW WE ENGAGE

Three ways to bring us in.

Scoped Assessment

Fixed scope, fixed price

A defined deliverable — a HARA, a TARA, a schematic review — priced and scheduled up front. Good for a single gap you need closed.

Embedded Engineering

Our engineer, your program

A core-team engineer works inside your program for its duration, alongside your team, on your cadence.

Program Ownership

We run the workstream

We own a safety case, a CSMS build-out, or a hardware design end to end and deliver it complete.

Three engineering disciplines, delivered by one team.
