Application Engineer II

Requirements:

• 5+ years of backend engineering experience, with strong proficiency in Java and ideally exposure to PHP; experience with Go, C#, or Python is also valued.
• Experience building and maintaining large-scale, high-volume systems — with a solid understanding of distributed systems, queuing, caching, concurrency, fault tolerance, and scalability.
• A background in financial systems, payments, or data-intensive applications is a big plus — you understand what it means to build systems where correctness, reliability, and performance are non-negotiable.
• End-to-end ownership mindset — you don't just execute tasks; you take initiative, shape ideas with a product-first approach, and think in terms of outcomes for merchants and the business.
• Strong communication skills, with the ability to work effectively with both technical and non-technical stakeholders across domains.

What you will be doing:

• Design, build, and maintain backend systems and APIs that operate at high scale and high frequency — where performance, fault tolerance, and reliability are critical.
• Take ownership of features end-to-end, from architecture and estimation through to delivery, production support, and continuous improvement.
• Contribute to ambitious migration and modernisation initiatives, decoupling legacy dependencies and building cleaner, more scalable foundations for the future.
• Transform complex technical and business requirements into well-designed, production-ready solutions — working closely with product and engineering stakeholders to shape what gets built and how.
• Participate actively in agile ceremonies including brainstorming, estimation, and sprint planning, bringing both technical depth and a product-first perspective to the table.
• Identify and resolve complex issues across distributed systems, applying creative problem-solving to challenges that sit at the intersection of engineering excellence and real merchant impact.

Perks and Benefits:

• Regular feedback and performance reviews to support your development.
• Fair and transparent salary reviews.
• Opportunities for growth, skill development, and career advancement.
• Support for exploring new roles, projects, and skills.
• Tools, trust, and opportunities provided to help you grow your way.
