About the Role
This role sits within Float’s Financial Products (FinProd) group, where we design and operate backend systems that move money and manage financial state. These systems power core capabilities such as bill pay and other financial workflows, where correctness, reliability, and trust are non-negotiable.
We are hiring across multiple levels for this role. Our interview process is designed to assess candidates objectively based on impact, judgment, and learning velocity, and we will level accordingly. As Float continues to grow, this team offers meaningful opportunities to take on increasing scope, ownership, and technical leadership over time.
This role is well-suited for developers who enjoy systems thinking, complex domains, and treating software development as a craft rather than just shipping CRUD.
What You’ll Be Doing
Design and maintain backend systems that support money movement and financial workflows.
Model complex data and state transitions with a strong focus on correctness and invariants.
Build and evolve distributed systems, including asynchronous workflows, retries, and failure handling.
Anticipate edge cases and scale challenges before they become production issues.
Apply disciplined testing and validation practices for high-blast-radius changes.
Partner with Product, Frontend, and Platform teams to deliver reliable customer outcomes.
Take ownership of systems in production, including reliability and post-incident learning.
What Success Looks Like (6–12 Months)
You own or meaningfully contribute to critical backend domains with high reliability and trust.
Financial workflows you work on scale cleanly as usage grows.
You surface and address edge cases early, reducing incidents and rework.
Teammates trust your judgment on complex system design and correctness.
Your work raises the quality bar for backend engineering at Float.
What We’re Looking For
Experience building backend systems beyond basic CRUD patterns.
Comfort reasoning about data flow, state transitions, and distributed system trade-offs.
Solid database fundamentals, including transactional integrity and performance at scale.
An ownership mindset for systems running in production.
Curiosity and adaptability — language or framework experience matters less than how you think.
Bonus: exposure to financial systems, ledgering, payments, or high-scale transactional platforms.

Collective Bar Raising
We hire for character, curiosity, and learning velocity before credentials. Titles matter less than impact, and every hire is expected to raise the bar for Float as a whole.

Team members within commuting distance of our Toronto office work in a hybrid model, while those based farther away primarily work remotely with occasional travel to Toronto for in-person time. Specific expectations can vary by role and will be discussed during the interview process.
