Staff Software Engineer - Payments

Narmi•New York, NY

5h•$215,000 - $233,000

About The Position

We are looking for a Staff Software Engineer to lead the technical evolution of Narmi Now, our flagship instant payments solution. Narmi Now is a direct-to-Fed integration that enables 24/7/365 real-time money movement via the FedNow® Service. As a Staff Engineer on the Payments team, you won’t just be writing code; you will be the architect of a highly resilient, low-latency processing engine. You will tackle the unique challenges of "faster payments," where the margin for error is zero and the need for sophisticated fraud prevention (Narmi Guard) is paramount.

Requirements

Deep Payments Expertise: Extensive experience building or scaling payment processing systems (ACH, Wires, Card Processing, or ideally, RTP/FedNow).
Systems Thinking: A proven track record of designing distributed systems that handle high-volume, mission-critical financial transactions with absolute data integrity.
Tech Stack Proficiency: Comfort working across a modern stack (Python/Django, React, AWS, PostgreSQL). Experience with event-driven architecture (Kafka/RabbitMQ) is a major plus.
Strategic Execution: The ability to balance "slow is smooth, and smooth is fast" — building for long-term stability while maintaining the agility of a high-growth fintech.
Experience: 8+ years of professional software engineering experience, with at least 2+ years in a Staff, Principal, or Lead capacity.

Responsibilities

Architect Real-Time Infrastructure: Lead the design and scaling of our direct connection to the Federal Reserve, ensuring 99.99% uptime for instant credit and debit transfers.
Drive Technical Strategy: Define the long-term roadmap for Narmi’s payment rails, transitioning from legacy batch processing to event-driven, real-time architectures.
Integrate Security & Fraud: Work closely with the Narmi Guard team to embed world-class identity decisioning and fraud mitigation directly into the payment flow.
Mentor & Lead: Act as a force multiplier for the engineering org, providing deep technical mentorship, setting code standards, and conducting high-impact reviews.
Cross-Functional Collaboration: Partner with Product and Implementation teams to turn complex regulatory requirements into seamless UI/UX experiences for both financial institutions and their end-users.
