Fractional Head of Engineering → CTO at Seed Allometry · Remote (Canada) ·
Fractional → Full-Time Allometry is the account underwriting platform for
asset-heavy operators. Each account gets a Pulse — a continuous rhythm of
signals scoring every commercial decision against margin and enterprise value
at the address level. ABM meets CPQ. The operating system for physical
revenue. 4 design partners paying. $30K ARR run rate in month one. 20 more in
pipeline. Raising $750K pre-seed, $250K committed, closing end of May.
allometry.com The Role We're looking for a fractional Head of Engineering to
own the technical foundation of Allometry through pre-seed and convert to
full-time CTO at seed close (~12 months). This is not a "review PRs and
advise" role. You'll be hands-on — hardening the architecture, building the
integration layer, and making the platform ready to scale to 150 customers.
The founder built the full product with Claude Code (50K lines in production,
16 modules, SOC II + WorkOS ready). It works, customers are paying, margin
recovery is proven. You can rebuild what needs rebuilding — that's expected
and welcome. But the product needs to stay solid and serving customers at
month 12 while you're building properly to scale to 150. Your job is to own
that balance. Time commitment: 15-20 hours/week fractional → full-time at seed
($2.5M target, ~month 12). Compensation: $5,000/month fractional + equity
grant. Full-time CTO comp at seed (market salary + co-founder-level equity).
What You'll Own Now (fractional, months 0-12): Architecture review and
hardening — the product works, make it bulletproof API design and integration
layer (ERP, CRM, FSM — no-rip-and-replace) Infrastructure and deployment
pipeline Data model integrity as Pulse compounds across accounts and addresses
Security posture (SOC II compliance is in place, keep it there) Technical
diligence with investors — you'll be in the room At seed (full-time CTO):
First engineering hires (2-3 ICs) Platform scalability for 150 operators,
thousands of addresses Humanoid orchestration layer (Phase 4 — same API,
different unit type) Technical roadmap ownership What We're Looking For Must
have: Built and shipped enterprise B2B SaaS platforms — not just features,
platforms API-first architecture experience — you've designed integration
layers that other systems build on Comfortable in a 50K-line codebase from day
one — you read code fast and form opinions faster Experience at a company that
went from early stage to real scale (Series A+) Strong opinions on data
modeling, especially for systems where the core entity is a location/address,
not just an account record Can context-switch between IC work and architecture
decisions weekly Strong signals: Background at Shopify, Stripe, Coveo,
Workleap, or similar — companies where platform engineering is the product
Experience with multi-tenant SaaS serving SMB/mid-market operators Familiarity
with field services, manufacturing, or deployment-heavy industries (you don't
need deep domain expertise — the founder has that) You've been a fractional or
early-stage CTO before and know how to be high-leverage on limited hours You
care about the intersection of software and physical operations — not just
another dashboard Not a fit if: You want to rewrite everything before
understanding what customers need it to do today You need a team under you to
be productive You're looking for a passive advisory role You've only worked at
large companies and haven't shipped in a <5 person environment Why This Role
You're not joining a concept. The product is live. 47 jobs through the Pulse
last month. 4 paying customers. Real margin recovery measured. You're joining
a working system and making it institutional-grade. You get the CTO seat. This
isn't fractional-forever. The path to full-time CTO is explicit and funded at
seed. You'll be the technical co-founder from day one of funded scale. The
founder built the product. You're not babysitting a non-technical CEO's
outsourced codebase. The product was built with Claude Code — 500K lines
written, rebuilt, chiseled to 50K in production. Rebuilding is on the table
and expected. But you'll work with a founder who understands every decision in
the codebase because he made them. The category is real. Asset-heavy operators
are a $7.5B addressable market running on spreadsheets and gut feel.
ServiceTitan proved the category is $100B+. We're building the underwriting
layer they missed. The long game is infrastructure. The Pulse that underwrites
a human technician today is the same system that routes a humanoid unit
tomorrow. You'd be building the technical foundation for the operating system
for physical revenue. About the Founder Ex-solo GP (backed B2B SaaS from
inception to $100M+). CRO across $5M-$50M asset-heavy companies. Apple.
Workleap. GardaWorld. Full-stack builder — shipped the entire platform solo.
