Working Location: Empire Tower (100% onsite, accessible via BTS Chong Nonsi)
Role Purpose
We're hiring a Backend Developer who loves designing high-availability systems, mentoring great engineers, and shipping code that scales. If you treat AI as a co-pilot (not an oracle), think in systems, and get a kick out of solving complex production problems
Responsibilities
- ⭐️ Own what you ship. Take full responsibility for your work — from design to delivery — and consistently hit the commitments you make to the team and stakeholders.
- ⭐️ Use AI to multiply quality and speed. Leverage AI coding assistants and agentic workflows to write better code, catch issues earlier, accelerate reviews, and improve engineering efficiency across the team.
- Architect for scale. Design and build high-availability, fault-tolerant backend services and APIs.
- Drive technical excellence. Set standards for code quality, CI/CD, security (PCI DSS), testing, and code reviews — and make sure the team lives by them.
- Lead incident response. Own root cause analysis for production issues and turn lessons learned into lasting improvements.
- Push the stack forward. Research emerging tech, run POCs, and bring the best ideas back to the team.
- Lift the team. Mentor mid- and junior-level developers through pair programming, code reviews, and knowledge sharing.
- Partner with the business. Collaborate on complex customer projects to find the right technical solution.
Requirements
Must-have:
- Backend / full-stack experience in production environments
- Proficiency in Java and/or .NET
- Hands-on with cloud (AWS or similar), Docker/Kubernetes, and serverless
- Hands-on experience with at least one AI coding assistant in real projects (not just trial use)
- Solid fundamentals: clean code, testing, code review, Git workflow
- Awareness of data security & responsible AI usage (no sensitive data in prompts, etc.)
Nice-to-have:
- Fintech/payment / high-TPS API background
- Experience with agentic workflows, MCP, custom skills, or prompt engineering at scale
- Contributions to internal tooling, dev productivity, or DevEx initiatives
- Exposure to observability stack (Grafana, Loki, Tempo)
Mindset we're looking for:
- Treats AI as a co-pilot, not an oracle — validates output
- Systems thinker, not just a task executor
- Comfortable sharing knowledge and lifting team capability
Minimum Qualifications (NEW)
- Bachelor's degree in Computer Science, Software Engineering, or related field.
- Proven experience delivering large-scale, high-traffic backend systems in production.
We offer an attractive remuneration package, a fast-paced and exciting working environment, and provide challenging opportunities for life-long learning and career development.
