About Plooto

Plooto is a Canada-born fintech company on a mission to give small and mid-sized businesses the financial power to succeed on their own terms. We make payments secure, accurate, and stress-free so businesses and their accountants can spend less time in the books, confidently manage cash flow, and make smarter decisions every day. We’re a team that builds with integrity, agility, and heart, and we’re looking for customer-minded pros who share our passion to join us as we scale.

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

Qualifications

Outline the experience, technical skills, and attributes required to succeed in the role. Include both must-haves and nice-to-haves if applicable.

Your background:

• 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)
• Experience implementing automated testing strategies (unit, integration, contract, and end-to-end testing)
• 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
• Ability to effectively use AI tools towards increasing velocity, efficiency and quality of deliverables
• Computer Science degree or equivalent

Bonus Points

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

Why Become a Plootonian?

If you’re looking to make a meaningful impact, look no further. We’re transforming the payments space in North America by delivering an unrivalled product experience to solve a real and pressing problem for SMBs.

The biggest reason small businesses fail is poor financial management and cash flow — and Plooto fixes that. We have strong product‑market fit, a massive opportunity ahead, and the backing of experienced fintech leaders.

You’ll join a team that cares deeply about customer impact, takes pride in our craft, and moves with urgency. We’re just getting started — and you’ll help shape the next chapter of our growth story.
