Staff Software Engineer

About us 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 We're hiring a Staff Software Engineer to be a technical leader across our entire platform. In this role, you'll 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 a hybrid role 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. 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

• 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 - you're 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 we're 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 we offer

• Competitive base
• Equity ranging 0.01-0.1%
• 3 weeks vacation
• 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!)
