Comprehensive healthcare package (Annual health check, Vaccine, Premium Health Insurance)
Flexible working hours with a standard 5-day workweek.
We hire for mindset first, technology second. To succeed here, you need:
Engineering Skills
Our Tech Stack: We primarily use Golang and [protected info] on the backend and PostgreSQL for our database. But we are open to any background (Java, Python, PHP, etc.)-we care about your logic, foundation, and problem-solving skills more than the specific language.
Critical Thinking: You don't just fix bugs; you find the root cause. You proactively think about edge cases, database bottlenecks, and security before you write code.
System Design (For Seniors): You understand how to design complex systems (Distributed systems, Databases) and can explain your choices clearly. You can design systems that stay fast even when traffic increases by 10x.
Product Mindset
User Focus: You understand that code is a tool to solve user problems. You care about the quality of the product, not just the quality of the code.
Curiosity: You ask "Why?" Why are we building this? Is there a simpler way? How does this help the business?
Collaboration
Ownership: You own your work, learn from mistakes. You don't wait for detailed instructions; you talk to the PM, understand the requirement, and deliver the solution.
Communication: You can explain technical problems to non-technical people (like Designers or other stakeholders) clearly and respectfully.
Teamwork: You value team success. You believe in code reviews and sharing knowledge. You help the team get better every day.
