Job description

Relay is a digital banking platform that gives self-made business owners the tools and know-how to be great with money- bringing clarity, confidence, and control to every dollar earned, so they can turn hard work into lasting success. We do this by replacing financial guesswork with real visibility, transforming cash flow from a constant source of stress into a clear signal owners can use to run stronger, more resilient businesses.

Our Engineering team is at the heart of building banking products that help millions of small businesses succeed. We’re on a journey to reinvent banking, and we’re looking for a curious, impact-driven Senior Software Engineer (Internal Tools) to join our growing team - someone who thrives on taking smart risks, experimenting boldly, and learning from every challenge.

This role is for someone who’s energized by removing friction. You'll replace manual processes with real software, turn spreadsheets and one-off scripts into scalable systems, and build the admin surfaces and workflows that let our internal teams support a rapidly growing customer base. The feedback loop is unusually tight: your users are your teammates, and you'll see the impact of what you ship within days. If you're motivated by building software that makes a whole company faster, you'll feel right at home here.

What You’ll Be Doing

• End-to-End Development: Own internal tool features across the full development lifecycle, from design and development through testing, deployment, and monitoring, ensuring reliability and performance at scale
• System & Infrastructure Ownership: Manage production systems, optimize infrastructure, and contribute to the availability, scalability, and resilience of our platform
• Internal Customer Focus: Run your own discovery by sitting with the teams you build for, understanding their workflows, and prioritizing based on real operational pain rather than a handed-down backlog
• Innovation & Continuous Improvement: Proactively identify areas for technical, process, and product improvement, helping the team raise the bar and influencing technical direction and long-term strategy

Who You Are

• You have 3+ years of full-stack software engineering experience; internal tooling is a plus
• You have led the development of significant components or features, delivering them successfully with minimal oversight
• You're energized by internal-facing work and see making teams more efficient as a meaningful engineering outcome
• You're comfortable doing your own product discovery, talking directly to internal users, asking why a process exists, and proposing a better one
• You mentor junior engineers, sharing expertise and fostering the growth and skill development of the entire team
• You proactively drive enhancements and lead initiatives to enhance code quality, optimize performance, and streamline development processes
• You're a lifelong learner, curious about new frameworks, best practices, and emerging technologies
• You're a collaborative team player, eager to pitch in, ask questions, and provide and receive feedback

Its a bonus (but not required) if you

• Have worked in startups or high-growth tech companies
• Have built internal tooling, admin platforms, or back-office systems, particularly in fintech, banking, or another regulated industry
• Have experience with JavaScript – we primarily use TypeScript, React, and Node.js
• Have working knowledge of AWS services (ECS, S3, RDS, Dynamo, Lambda) and continuous deployment pipelines

For candidates who demonstrate full readiness for the defined scope of the role, the typical starting salary is $160,000 CAD.

Why Relay Might Be the Perfect Fit For You

• You push relentlessly for reinvention: You're always asking "how can this be better?" -- in your work, in your craft, in yourself. Comfort is a signal to push harder, not coast. You'd rather build something better than defend something familiar.
• You crave autonomy: We trust our team with big challenges and the freedom to solve them. If you're someone who takes initiative, is comfortable taking risks, and seeks input when needed, you'll find the freedom here empowering.
• You own your work: You take pride in your work, follow through on commitments, and feel a deep sense of responsibility for outcomes, not just tasks.
• You build with AI, not just use it: You're actively embedding AI into how you work, pushing what's possible, and bringing your team along with you.
• You care about impact, not noise: You care deeply about the substance of your work. You measure success by results, not recognition, and you let your work speak for itself.
• You're energized by complexity and ambiguity: You enjoy tackling problems that don't come with a playbook. You're comfortable building from scratch, iterating as you go, and collaborating to shape the best path forward.
• You seek out feedback: You see directness as respect, not criticism. You actively seek input, sit with hard truths, and use feedback as fuel for improvement.
• Small businesses are why we're here: Relay exists to help them thrive -- and that mission has to resonate with you.
