• Solid understanding of backend engineering principles, with the ability to review and contribute to application code when required.
• Comfortable taking ownership of projects end-to-end within dynamic, fast-growing teams.
• Strong communication, collaboration, and problem-solving skills, combined with a product-oriented mindset.

Benefits

• Competitive salary package and equity participation opportunities.
• 25 days of annual leave in addition to public holidays.
