Member of Technical Staff: Backend
Monk is an AI-native accounts receivable platform for B2B companies. We automate billing, collections, and payments so finance teams can turn outstanding invoices into cash, faster.
We believe the AR stack is broken and the finance function deserves much better. We are bringing AI, speed, and real craftsmanship to a space that has been ignored for too long.
We are looking for a backend engineer to join us in NYC in person. You will own the foundational systems that everything else runs on: the data layer, the integrations, the AI execution environment, and the infrastructure that has to work every time money moves. We do not care about your education, age, or past titles. All that matters is whether you can build systems that scale, stay up, and get faster as we grow.
What you will do
Own and advance the backend platform that powers Monk's platform
Design and operate the integration layer across ERPs, payment processors, banks, and accounting systems.
Architect data pipelines that ingest, normalize, and reconcile financial data across dozens of customer environments with different schemas, edge cases, and failure modes
Own system reliability. Monitoring, alerting, incident response, and the kind of operational rigor that means customers never notice when something goes wrong
Drive our security and compliance infrastructure: SOC 2, encryption, access controls, audit logging. Build it into the system, not bolted on after the fact
Make the systems easy to debug.
Set the technical bar.
Who you are
4+ years building and operating production backend systems. You have built, broke, and scaled them yourself.
A T-Shaped engineer. Deep in at least one thing, broad enough to advance the rest, and able to do this in Typescript/Node.
Expert in Postgres, AWS, Vercel, data processing pipelines, observability.
Understand technical tradeoffs that you are making and when you must improve..
AI-native, not AI-dependent. You move fast with it, and know exactly when to not do it.
Owner. You do not file tickets about infrastructure problems. You fix them, then make sure they cannot happen again
AI-native. You use AI to move faster and you are excited to build the infrastructure that makes AI agents production-grade
Excited to build in person in Flatiron, NYC
Bonus if you have: (1) built or operated fintech/payments systems, (2) built data processing or streaming services at scale.
Why join
Competitive salary, meaningful equity, full health/dental
Freedom and trust. There are no spec handoffs.
We are all in. Expect motivated teammates who ship fast and hold a high bar
Experienced founders with real traction and happy customers
