About the role

Original posting from Relayfi via Ashby

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 to join our growing team – someone who thrives on taking smart risks, experimenting boldly, and learning from every challenge.

You’ll tackle complex problems head-on, ship high-quality, robust code, and shape systems that power our products. This is a unique opportunity to work across our full product suite, influence technical decisions, and deliver end-to-end features that customers love. If you’re excited about building best-in-class fintech products in a fast-growing, collaborative environment, this is the role for you.

What You’ll Be Doing

  • End-to-End Development: Own features across the full development lifecycle – from design and development to 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
  • Cross-Functional Collaboration: Partner with Product, Design, and cross-functional teams to build solutions that meet customer and business needs
  • Innovation and 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
  • You have led the development of significant components or features, delivering them successfully with minimal oversight
  • 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
  • You take ownership end-to-end, solving problems creatively and proactively, while keeping the customer and business impact front-of-mind

It’s a bonus (but not required) if you

  • Have worked in startups or high-growth tech companies
  • 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

Our Tech Stack

  • Front-end: React, Typescript, React Native
  • Back-end: Node.js, Typescript, Terraform, AWS (DynamoDB, RDS Postgres, Lambda, S3, SQS, SNS, SES, ElasticSearch, ECS)
  • Tools: Cursor, Claude, GitHub, GitHub Actions, Datadog, Jira, Metabase

The Interview Process

  • Stage 1: A 45-minute Google Meet video call with a member of the Talent team
  • Stage 2: A 60-minute live coding exercise with two members of the Engineering team
  • Stage 3: A 60-minute Google Meet video call with two Engineering Managers
  • Stage 4: A take-home system design challenge, followed by a 60-minute Google Meet video call review with two members of the Engineering team
  • Stage 5: A 45-minute in-person interview with a member of the Leadership 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.

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.
