Shinzo (https://shinzo.network)| USA/Canada + REMOTE | Multiple Full-Time Roles

We're building the read layer for blockchains. The irony of "trustless" applications depending on centralized indexers like Alchemy or The Graph isn't lost on us—we're fixing it.

Shinzo embeds indexing directly into validators, turning blockchain data into a cryptographically verifiable public good. No trusted intermediaries, no API keys, no "please don't rate limit me" prayers at 2am.

Stack: Go, Rust, WebAssembly, Merkle CRDTs, recursive SNARKs, LibP2P, GraphQL, Cosmos SDK/EVM

Hiring:

-DX Engineer - Indexer Migration - https://bit.ly/3ybwhbn

-Senior Blockchain Indexer Engineer - https://bit.ly/4shqkly

-Senior Cross-Chain Smart Contract Engineer - https://bit.ly/49bzjan

-Protocol Engineer - Blockchain - https://bit.ly/4sdrica

We're pre-mainnet with real technical differentiation—not another "decentralized" project that's actually three EC2 instances in a trench coat. If you've ever been mass-migrated off a deprecated API endpoint or debugged why your subgraph stopped syncing, you understand the problem we're solving. We care more about what you can build than where you went to school.

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.

Email is hidden — tell me about a messy integration you've fixed.
