Full Job Description
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

  • 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 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 thrive in fast-paced, dynamic environments and are comfortable navigating ambiguity and change
  • You're a collaborative team player, eager to pitch in, ask questions, and provide and receive feedback


It's 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

  • Stage 2: A 60-minute Google Meet video call with two Engineering Managers
  • Stage 3: A 60-minute live coding exercise with two members of the Engineering team

Our Compensation Approach

We believe Relayers should feel rewarded for the impact they have on our mission and growth. Compensation follows impact. As impact increases, compensation grows, and we do not limit compensation changes to a once-a-year review cycle.

The annual salary range for this role is $144,000 CAD to $176,000 CAD.

For candidates who demonstrate full readiness for the defined scope of the role, the typical starting salary is $160,000 CAD. Offers below this point reflect candidates we believe can grow into the full scope of the role with support and development. Offers above this point reflect impact that meaningfully exceeds the role's defined expectations or an expanded scope from day one.

We encourage you to have a conversation with your recruiter and ask questions about compensation throughout the hiring process. For more information on our compensation philosophy and perks and benefits, visit our Candidate Hub.
