Integral | Full-Stack Developer | REMOTE (US)

I'm Stephen, founder of Integral. We're a fractional CTO firm for scaling businesses ($10M-$100M) drowning in SaaS sprawl, broken automations, and data scattered across 20+ tools.

What you'd work on: - Building unified dashboards pulling from Shopify, Stripe, HubSpot, and ad platforms (Meta, TikTok, Google) - Multi-system automations: HubSpot → SamCart → Klaviyo → Circle cancellation cascades - Custom web apps (React/TypeScript, Supabase) when off-the-shelf fails - Debugging/replacing complex Zapier/N8N workflows across client ecosystems - API integrations with whatever the client uses—we've touched trigger.dev, hubspot, asana, samcart, AWS, and many more this month alone

The role: You own your clients. Not "execute tickets"—actually understand their business, propose solutions, join calls (only when needed.) Small team, high autonomy, direct founder access. We're integration specialists, not a body shop.

Stack: TypeScript, React, Python, Node, Supabase/Postgres, REST APIs — end to end. Bonus points if your execution is deeply engineering-driven.

What we're not: Big tech process, Jira hell, or "ticket monkey" work. We move fast on real problems for real businesses. However, that does not mean we aren't highly organized and efficient.

Contractor, ~20-30 hrs/week to start. US timezone overlap required.

stephen@gointegral.co — tell me about a messy integration you've fixed.

Office Hours | Software Engineer (all levels) | SF, NYC, or Remote (US) | https://officehours.com We connect organizations (AI labs, startups, investors, consulting firms) with experts for paid calls, surveys, and model training. We're profitable and growing quickly.

Some of the problems we're actively working on: - Workflow automation: Designing agent-driven workflows that are driving real impact for the business and our customers - Search: Building semantic + keyword retrieval over large amounts of data - Knowledge graph: Modeling relationships between people, companies, topics, and interactions to power recommendations and discovery - New products: 0-1 work across new interaction types and mediums

Stack: TypeScript, Node, Postgres, OpenSearch, Temporal | React, Next.js, Tailwind | AWS
