Senior Backend Engineer

About Plooto

Plooto is an all-in-one payment automation platform that helps businesses and accounting firms manage payables and receivables. More than 14,000 companies use Plooto to automate financial workflows, move money, and reconcile with their accounting systems.

We are building the financial operations platform small and medium-sized businesses can rely on to run with greater control, efficiency, and confidence.

About the Role

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.

Key Responsibilities

What you'll do:

Own the design and delivery of scalable backend services using .NET and Azure

Architect and evolve event-driven, distributed systems that process high volumes of financial transactions

Build API-first services with strong contracts, reliability, and observability

Lead complex technical initiatives from design through production rollout

Make pragmatic architecture decisions that balance speed, scalability, and long-term maintainability

Partner closely with Product and Design to translate ambiguous problems into elegant technical solutions

Improve performance, reliability, and system resilience as we scale

Raise the engineering bar through thoughtful code reviews, design discussions, and mentorship

Inspire and share your engineering passion across the whole engineering org in our regular Lunch & Learn sessions

Contribute to a culture of experimentation, ownership, and continuous improvement

Work cross-functionally in Plooto, distilling the needs of our strategy into actionable engineering output
