CN Craig North Fractional CTO & Engineering Advisory

Fractional CTO · Embedded · Automotive SDV · AI

I help technology companies turn hard engineering into shipped products.

Twenty years building software-defined vehicles, embedded platforms, and AI systems — and the global engineering organizations that ship them — at Tesla, NIO, Samsung, and Weavix. I work with founders, CEOs, and investors as a fractional CTO, architecture reviewer, and technical advisor when the cost of getting it wrong is high.

Who I work with

You know exactly when to call me.

I take a small number of engagements where deep automotive, embedded, and engineering-leadership experience moves the needle — usually one of these moments.

Hardware & automotive startups

Scaling an embedded or software-defined-vehicle platform — and the team behind it — without the program slipping 12 months.

CEOs without a senior technical voice

You need executive-level engineering judgment in the room — architecture, hiring, delivery — but not yet a full-time CTO.

Investors & boards (VC / PE)

Technical due diligence before you write the cheque: is the architecture real, is the team able to deliver, what's the hidden debt?

Engineering leaders scaling up

VPs and directors taking an org from 20 to 200 — structure, process, and the hard calls — with someone who has done it.

How I help

Senior technical leadership, scoped to the decision in front of you.

Every engagement is built around an outcome and a deliverable — not open-ended hours.

01

Architecture Review

An independent, senior read on your software and systems architecture before it goes to production — risks, scaling limits, and what to fix first.

You getWritten findings, prioritized risk register, and a remediation roadmap.
02

Fractional CTO

One or two days a week of executive technical leadership — architecture, roadmap, hiring, and the conversations the board needs to hear straight.

You getA technical leader in the room, owning the hardest calls.
03

Engineering Org Assessment

A clear-eyed evaluation of process, technical debt, hiring, and delivery velocity — and exactly where the organization is leaking time and quality.

You getAn org & delivery assessment with a 90-day action plan.
04

Technical Due Diligence

Architecture, team, and roadmap assessments for VC and PE firms before an investment — what's real, what's risk, and what it will take to scale.

You getAn investment-grade technical diligence memo.
05

Executive Coaching

Mentoring for engineering managers, directors, and VPs stepping up — from someone who has built and led orgs at exactly that scale.

You getMonthly 1:1 coaching and on-call judgment when it counts.
06

Embedded & SDV Strategy

Platform and product strategy for software-defined vehicles and connected hardware — silicon to cloud, security, OTA, and real-time data.

You getA defensible platform architecture and product strategy.

Selected work

Executives don't buy experience. They buy confidence.

Not just where I worked — what I personally drove, why it was hard, and what shipped because I was in the room.

TeslaFirmware Engineer → Manager · Body Controls · 2011–2016

I came in to write firmware and built a body-controls team of 12 full-time engineers — backed by 8 regular interns — with zero attrition, without ever stepping away from the code. That team delivered 14 ECUs for Model X, the Model S gateway and the foundations of Tesla's over-the-air updates, a ground-breaking BLE key fob, and cost-down designs for Model 3, then ramped Model S and Model X through the production line. When the Model S door handle had to be reinvented — hardware and software — just six weeks before start of production, we rebuilt it from scratch and still hit the date.

NIODirector → VP Digital Systems · 2016–2019

NIO was a bet — a brand-new EV company with global ambition and almost nothing built yet. I built and led a 90-engineer digital-systems organization from the ground up across San Jose, Shanghai, and Munich, and helped recruit six VPs — former colleagues — to lead other organizations across the company. I designed four vehicle platforms plus the safety-critical, connected-vehicle architecture behind them, including the record-setting EP9 electric hypercar. I set NIO's software-defined-vehicle vision years ahead of most OEMs, generated four US patents, and delivered the digital backbone that helped carry the company to its NYSE IPO.

SamsungSr Director, Software · Smart Machines · 2019–2020

Samsung handed me a hard mandate: take on Mobileye. I directed a 30-engineer organization architecting Samsung's automotive compute and computer-vision stack — silicon, middleware, and AI designed as one system — for next-generation ADAS and autonomous driving. The edge wasn't any single layer; it was making the whole stack, from chip to perception, move together. That kind of cross-domain bet is exactly where I do my best work.

WeavixSVP Software Engineering · Current

At Weavix I lead engineering across six domains at once — embedded, Android, cloud, AI, data, and hardware — and drove the bring-up and rollout of an infrastructure-free mesh smart radio: a device that keeps frontline teams connected where there is no network to rely on. It's the kind of problem I look for — ambitious, undefined, and only solvable by making many disciplines work as one. And I'm still close enough to the architecture to know it works.

Infrastructure-free mesh radio brought to market

Spans six domainsZero-to-marketStill hands-on

The thread through all of it: I take ownership of the undefined, high-stakes problem, build the team and architecture around it, and stay close enough to the code to make sure it ships. That's the value I bring to your hardest engineering decision.

Proof

Results that speak for themselves.

Standout outcomes from two decades of shipping — the track record behind the advice.

Craig achieved something that was truly unheard of — 14 ECUs with a team of 12, delivering over 800 features in 18 months.
Body Controls Tesla · 2011–2016
Stood up a 90-engineer organization across three continents and four vehicle platforms — and called software-defined vehicles years before the rest of the industry caught on.
Digital Systems NIO · 2016–2019
Fused silicon, middleware, and AI into a single computer-vision platform built to take on the category leader in autonomous driving head-on.
Smart Machines Samsung · 2019–2020
Took an infrastructure-free mesh smart radio from concept to market across six engineering domains at once — connectivity where no network reaches.

Where I go deep

Four areas. Everything else supports them.

01

Automotive SDV

Software-defined-vehicle platforms — architecture, security, OTA, connected services — from silicon to cloud.

02

Embedded systems

Safety-critical, real-time firmware and systems engineering grounded in ISO 26262 and 20 years of shipping.

03

Engineering leadership

Building and scaling organizations from 20 to 200 across continents — hiring, structure, and delivery.

04

AI-enabled products

Computer-vision and AI systems taken from prototype to production in manufacturing, automotive, and consumer.

Why it matters

Inventor of four US patents covering over-the-air updates, secure automotive networking, firewall architecture, and vulnerability detection — the kind of foundational, hard-to-get-right systems that decide whether a connected product is safe to put on the road. That's the lens I bring to your architecture.

How I work

An executive who is still close enough to the code to know it works.
— I lead from the front, design for the real-world constraints, and leave behind teams that outperform without me.
