Founding Backend Engineer; Node.js​/Python​/AWS​/FinTech​/equity​/A* Team​/NY

Founding Backend Engineer (Node.js / Python / AWS / Fin Tech) / $260,000 + equity / A
* Team / NYC (on-site)*

You’ve built systems that scale. You've handled data flows, API contracts, infra, and uptime under pressure. You don’t just ship code - you design reliable, composable backends that power real products. You want full technical ownership. This is that role.

The Company

A venture-backed AI infrastructure startup is assembling its founding team in New York. Their platform powers mission-critical, real-time decisions across healthcare, logistics, and defense. Think multi-agent orchestration, ultra-low latency pipelines, and systems where milliseconds matter.

The Team

The founders are proven operators, and the early crew is made up of A
* engineers from elite product orgs. Everyone builds. Everyone ships. Everyone is here to raise the standard. If you want to own architecture, ship end-to-end & work with people who think in systems, with no speed cameras - THIS is the room.

Profile

You're a backend engineer with startup grit and system design instincts. You’ve built scalable services, performance-critical APIs, and data pipelines under pressure. You understand not just code, but runtime, throughput, and bottlenecks. You take raw ideas, system requirements, and hard technical constraints, and turn them into resilient, production-grade software.

They’re looking for people who:

• Have built 0→1 systems in fast-paced, high-ownership environments

• Design and implement clean, low-latency REST and event-driven APIs

• Handle structured and unstructured data with Postgre

SQL, S3, or streams

• Think about availability, observability, and infrastructure as code

• Optimize for cold starts, throughput, latency, and cost

• Are comfortable containerizing, deploying, and tuning services in Docker + K8s

• Use cloud-native primitives and build with AWS-first thinking

• Know how to debug a flaky pod, a noisy query, or a dropped message

• Thrive with end-to-end ownership and love building things that work

In this role, you’ll:

• Build the core backend of a real-time decision platform

• Own API design, data pipelines, system architecture, and infrastructure choices

• Ship services with clear interfaces, strong monitoring, and fault tolerance

• Optimize performance across the stack - from request times to DB queries

• Collaborate tightly with frontend and product to shape features from idea to ship

• Define best practices for backend engineering from the ground up

• Help shape engineering culture, standards, and hiring from day one

What’s on offer:

• $260,000 base salary + equity

• On-site 5 days in a focused engineering office, downtown NYC

• Early ownership on a serious product with immediate use cases

• Backing from proven operators who have built and scaled before

• Clear direction, high standards, no micromanagement

Interview Process:

1) Technical Deep Dive

2) Technical Assessment or Live Pairing

3) Final Interview focused on mindset and team fit
