Senior Backend Engineer

Plooto

About The Position

Plooto powers payments and cash flow management for 14,000+ businesses across North America — and we’re just getting started. We’re rebuilding and scaling the next generation of our fintech platform, and we’re looking for a Senior Backend Engineer who wants real ownership, real scale, real impact, and cares deeply about system design, scalability, and writing clean, testable code that stands the test of time. This is not a feature-factory role. You’ll design and build high-throughput, cloud-native systems that move money, power complex workflows, and deliver real-time financial insights. You’ll help shape architecture decisions, influence engineering standards, and raise the technical bar across the team. If you thrive in high-growth environments, care deeply about clean system design, and enjoy solving hard distributed systems problems — you’ll feel at home here. We move fast. We debate ideas, not egos. We hold a high bar. And we win as a team.

Requirements

5+ years of professional backend engineering experience (preferably in high-growth or product-led environments)
Strong expertise in C# (or another strongly typed language) and modern backend design principles
Proven track record of writing production-grade, testable, maintainable code
Deep experience designing and building RESTful APIs in production
Hands-on experience with cloud-native architectures (Kubernetes, serverless, managed services), ideally in Azure
Experience building or operating distributed, high-throughput systems
Experience with event-driven architectures and streaming systems (Kafka or similar)
Strong understanding of data storage patterns across RDBMS and NoSQL systems
A bias toward ownership, action, and accountability
Ability to navigate ambiguity and drive clarity in fast-moving environments
Previous track record working successfully in a cross-functional team environment
Computer Science degree or equivalent

Nice To Haves

Experience in fintech, payments, or regulated domains
Prior startup experience where you helped scale systems and teams
