Job description

Hiring: Staff Software Engineer, Full Stack (Hybrid - NYC)

A fast-growing fintech startup modernizing the $30T fund administration industry is looking for a Staff Software Engineer to join a tiny team alongside the CTO and principal engineer. This isn't a "pick a ticket" role - you'll own entire verticals end-to-end, from data model to API to UI to deployment.

What you'd be building:

• A real-time calculation engine for allocations, NAV, and capital accounts - every number ties out to the cent
• Full lineage on every figure, traceable back to its exact source
• Durable workflows orchestrating LLM agents, deterministic validators, and human sign-off
• Production money movement - bank connections, payment rails, automated reconciliation
• An automated audit layer that continuously checks the books for drift and misattribution
• A semantic "ontology" model that generates the platform's types, auth rules, and graph schema
• Authorization modeled as live graph queries over the fund hierarchy
• The web, mobile, and agentic Excel surfaces clients use daily

What they're looking for:

• 8+ years as a true engineering generalist
• Deep TypeScript across the stack (React front-end, GraphQL/gRPC services)
• Experience building systems where money has to reconcile - payments, billing, ledgers
• Comfort with complex, deeply hierarchical, versioned data
• Real distributed-systems chops - idempotency, retries, durable execution
• Daily hands-on use of AI, with production LLM experience behind real guardrails
• AWS/Kubernetes architecture ownership

Bonus points:

founding engineer experience, time at a top-tier fintech (Ramp, Addepar, Square, Revolut-caliber), or shipped AI-native products with real adoption.

Comp:

$200K-$250K base + competitive equity + full benefits (health, vision, dental, 401k). Three days onsite in NYC.

Backed by top-tier investors, built by veterans from places like Bridgewater, Meta, IBM Watson, and Elemental Cognition - this is a rare shot to help rebuild an industry that still runs on spreadsheets and PDFs.
