About Loop
Loop Financial is 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 growth, and simplify their operations.

About the Role
I am Yan, Head of Engineering at Loop, and I’m hiring a Staff Software Engineer to be a technical leader across our entire platform. In this role you will 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. The position is onsite at our downtown Toronto office (Adelaide and Spadina).

What You’ll 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 – you’ll write code, not just draw diagrams

What We’re Looking For

8+ years building and scaling distributed systems

Full‑stack expertise – 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 – understand why we’re building, not just what

Ability to explain complex technical concepts to non‑technical stakeholders

Ability to improve the people around you

Bonus  – Security engineering background, accounting/reporting knowledge, experience with our stack (Ruby, Postgre

SQL, React).

What We Offer

Salary range CAD $170,000 to CAD $200,000 base annual, commensurate with experience

Equity ranging 0.01–0.1%

3 weeks vacation

Enrollment in group health benefits after probation period

Kitchen full of snacks and drinks

Catered lunch on Fridays (we take recommendations!)

The Challenge
Loop is adding real‑time payment rails (think Fed Now or Real‑Time Rail Canada). In under 500 words, outline the key architectural questions you would want answered before designing this integration. What are the biggest risks? What would you prototype first? Don’t design the whole system – show how you think about large technical decisions.
