About The Opportunity We're looking for a talented and experienced Senior Full Stack Developer to join our growing engineering team. This isn't just another job, it's a chance to work on meaningful products, tackle interesting technical challenges, and genuinely shape the direction of our software. You'll be working across the full stack, from classic web technologies to modern cloud-native architectures, so breadth and adaptability are key.

If you're someone who loves solving hard problems, takes pride in clean and maintainable code, and thrives in a collaborative environment, we'd love to hear from you.

Duties include but are not limited to:

• Collaborate closely with product, design, and other engineering stakeholders throughout the development lifecycle
• Participate in code reviews, technical discussions, and contribute to setting engineering standards
• Mentor junior developers and share knowledge across the team
• Troubleshoot production issues and own resolution end-to-end

About You Beyond the tech, we care about who you are as a developer and teammate.

The successful candidate will have the following:

• 5+ years of professional software development experience, with a strong full-stack background
• Comfortable navigating both legacy codebases and modern architectures without losing your mind (or your sense of humour)
