Staff Software Engineer

About the Role

Hi Im Yan Head of Engineering at Loop and Im hiring a Staff Software Engineer to be a technical leader across our entire this role youll set architectural direction mentor engineers and build critical systems yourself - from our core ledger and money movement infrastructure to the product features that customers interact with daily.

This role is an onsite position at our downtown Toronto office (Bay and Bloor).

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.

Were 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 Youll Be Doing

• Lead architectural decisions across the full platform - backend frontend infrastructure
• Build end-to-end features while setting technical direction for the team
• Architect our core ledger money movement systems and customer-facing product
• Partner with product and leadership to shape technical strategy
• Make technical decisions that balance innovation with reliability
• Own resolution of complex technical issues across the stack
• Mentor engineers and raise the bar for technical excellence
• Stay hands-on - youll write code not just draw diagrams

What Were Looking For

• 8 years building and scaling distributed systems
• Full-stack expertise - youre comfortable across backend frontend and infrastructure
• Experience with financial systems payment platforms or high-stakes data applications
• Track record architecting data-intensive highly concurrent applications
• Expertise in fault-tolerant system design and consistency trade-offs
• Strong product instincts - you understand why were building not just what
• You can explain complex technical concepts to non-technical stakeholders
• You make others around you better

Bonus: Security engineering background accounting/reporting knowledge experience with our stack (Ruby PostgreSQL React).

What Does It Take to Be a Looper

Loop is not for everyone. And thats intentional.

Were building the financial infrastructure that helps businesses move money across borders and we move fast. We take ownership and trust each other to get things done. From day one your impact will be felt immediately.

And because of that we need builders. People with grit who take full ownership thrive in fast moving environments and are comfortable figuring things out as they go.

If that sounds like you we want to hear your story.

What we offer

• Salary range CAD$160000 to CAD$180000 base annual commensurate with experience
• Equity ranging 0.01-0.1%
• 3 weeks vacation
• Enrollment in groups 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:

Loop maintains its own ledger as the source of truth for all customer balances but we depend on banking partners to actually move money. These partners each have their own ledgers their own formats and their own timing some settle in real-time others in batches and some send corrections days later.
When our ledger and a partners ledger disagree we have a problem. Maybe a payment was processed on their side but we never got the webhook. Maybe we recorded a debit that they rejected silently. At scale these discrepancies compound and for a financial platform even a single cent off is unacceptable.
In under 500 words outline how youd approach building a reconciliation system that continuously verifies Loops ledger against its banking partners. What are the key architectural decisions What are the hardest failure modes to handle How do you balance automation with human intervention What would you prototype first
Dont design the whole system show us how you think about a problem where correctness is non-negotiable but perfect information is never guaranteed.
