Senior Backend Developer - Toronto - Bank On Loop

Description

We're a fast-growing fintech startup building the only truly cross-border banking platform. We help businesses seamlessly manage money around the world so they can access more markets, accelerate their growth, and simplify their operations. We're looking for ambitious people to join our mission.

We're looking for engineers with a product mindset - people who think about the user's problem first, not just the component they're building. You'll work directly with stakeholders, make trade-off decisions, and own outcomes, not just output.

About the Role

Hi, I'm Yan, Head of Engineering at Loop, and I'm hiring a Senior Backend Developer to architect and build our payment platform and financial ledger system. In this role, you'll build the systems that move money - the foundation everything else depends on.

This is an onsite position at our downtown Toronto office (Adelaide and Spadina).

Why We Exist

Small businesses have been underserved by traditional banks. Most businesses operate globally, yet moving money across borders is still painfully hard. Banking fees are opaque, while the process and time to send or receive money internationally is decades old. The tools offered to businesses are only suitable for companies with finance and treasury teams of 20.

Loop exists to change that.

We're building the banking infrastructure for businesses that operate globally by default. Multi-currency accounts. Seamless international payments. Modern systems to manage company finances. The things that should have existed years ago.

What You'll Be Doing

• Build and support our Payment Infrastructure with strict data integrity
• Work in a cross-country environment handling data segregation and legal compliance across jurisdictions
• Implement workflow orchestration with for complex payment flows and system consistency
• Work directly with stakeholders to understand problems and define solutions
• Make informed technical decisions that balance user needs, business goals, and engineering constraints
• Build integrations with banking partners and payment processors
• Design for fault-tolerance, recovery, and comprehensive audit trails
• Develop end-to-end features that help businesses manage money across borders" as the first bullet. Makes it clear they're building product, not just infrastructure

What We're Looking For

• 5+ years backend development, 3+ years in financial systems
• Deep understanding of financial ledgers and double-entry bookkeeping
• Experience with event sourcing, CQRS, and message brokers (especially Kafka)
• Distributed systems expertise - consistency, availability, fault tolerance
• Product mindset - you care about the problem you're solving, not just the system you're building
• You think about what happens when things go wrong

Bonus: , event architecture, regulatory knowledge, SWIFT/SEPA/Fedwire familiarity.

What we offer

• Salary range CAD$140,000 to CAD$170,000 base annual, commensurate with experience
• Equity ranging %
• Enrollment in group's health benefits after probation period
• This role is onsite in our downtown Toronto office
• Kitchen full of snacks and drinks to keep you going throughout the day
• Catered lunch on Fridays (we take recommendations)

The Challenge

Before we talk, show us how you think:

A batch of cross-border payments settles overnight. In the morning, reconciliation shows discrepancies: some transactions are off by pennies, others by dollars. The total doesn't match what we expected after FX conversion.

In under 500 words, walk us through how you'd investigate this. What are the likely causes? What data would you look at first? How would you design systems to prevent or catch this earlier?
