At Sage Recruiting, we're partnering with a well-funded, late-stage fintech startup that's transforming how people manage their finances. Our client’s innovative platform combines behavioural psychology with cutting-edge technology to help users maximize happiness through mindful saving, spending, and investing. Their tools make financial management intuitive, rewarding, and easy to adopt.

Role Overview:

We are hiring both Intermediate and Senior Software Engineers to join a brand-new Platform Engineering team. You’ll work closely with the Director and VP of Engineering to help design and build a greenfield B2B SaaS product from the ground up.

If you're at an intermediate engineer (2–4 years of experience), you'll contribute to critical development work, collaborate closely with senior engineers, and deepen your skills across cloud services, APIs, and scalable architecture.

If you're a senior engineer (5+ years of experience), you'll take ownership over key areas of the platform, help design the initial architecture, lead development efforts, and mentor junior engineers as the team grows.

This is a rare opportunity to get in early on a high-impact product and help shape its future direction.

Key Responsibilities:

• Collaborate with cross-functional teams (engineering, product, design) to build scalable, cloud-native software solutions.
• Develop and maintain robust, developer-facing and B2B APIs.
• Design and optimize systems for performance, reliability, and maintainability.
• Build applications using AWS cloud services.
• Contribute to establishing coding standards and technical best practices.
• (Senior level) Lead technical design discussions, mentor team members, and guide architectural decisions.

Must-Have Skills:

• Experience building and integrating with APIS (B2B or developer-facing experience is ideal).
• Hands-on experience with AWS or similar cloud services.
• Strong understanding of software engineering fundamentals (data structures, algorithms, system design).
• Excellent communication and collaboration skills.

Nice-to-Have Skills:

• Exposure to Java or Kotlin.
• Previous experience working in startups or FinTech environments.

Salary Ranges:

• Intermediate: $110,000 – $140,000 CAD
• Senior: $150,000 – $170,000 CAD
• Vacation, Dental, Extended Health Care
• Accidental Death and Dismemberment Insurance

Why Join Us:

• Greenfield Development: Help build a brand-new platform from scratch alongside seasoned leadership.
• Career Growth: Whether you're intermediate or senior, there's a clear path for advancement into senior engineering, technical leadership, or team lead roles.
• Impactful Work: Your contributions will directly influence the product’s success and growth.
• Stable Environment: Work at a well-funded, late-stage startup that combines innovation with job security.
• Comprehensive Benefits: Competitive salaries and full benefits packages.

If you’re passionate about technology, motivated to build something from the ground up, and ready to grow alongside a forward-thinking fintech company, we would love to hear from you!
