Freelance Back-End Engineer

About Luxehouze Luxehouze is a fast-growing omnichannel luxury marketplace operating across Indonesia and Singapore, serving high-value customers in watches, fashion, and beauty.

We operate in an environment where trust, speed and excellence matter, and where outcomes matter more than activity.

We are looking for a Freelance Back‑End Engineer, who takes responsibility naturally, thinks in outcomes and wants to build, improve, and scale — not just “execute tasks.”

What Will Be Challenging

Expectations are high and visible.

Problems may be ambiguous and fast‑moving.

Priorities can change as the business scales.

Feedback is direct and frequent.

Performance is measured by results, not intentions.

If you require rigid structure, narrow scope, or close supervision to perform well, this environment may not be a good fit.

Responsibilities

Develop, maintain, and improve back‑end services and APIs with a strong focus on system impact, code quality, and production readiness.

Analyze requirements and existing system conditions before implementation to ensure the solution aligns with business and technical goals.

Take end‑to‑end ownership of assigned tasks, from understanding requirements, implementation, testing, until deployment and stability.

Work with Front End Engineers through clear API contracts to ensure smooth system integration.

Apply analytical and system thinking when solving problems, especially in complex or high‑pressure situations.

Maintain code quality by applying unit testing, participating in code reviews, and following engineering best practices.

Handle bugs, incidents, and performance issues in a structured and calm manner, especially during release or high‑pressure periods.

Requirements & Qualifications

Graduate from Bachelor, Diploma 3, or Diploma 4 degree from IT, Software Engineering, Computer Science, or other related majors.

Have a minimum of 1‑2 years of experience as a Back End Engineer or similar role.

Strong proficiency in Golang with clean, readable, and maintainable coding practices.

Strong sense of ownership and responsibility, able to take initiative and handle tasks end‑to‑end while collaborating effectively with the team.

Strong analytical thinking and problem solving skills, especially when handling system issues or production incidents.

Experience with document databases like MongoDB.

Solid understanding of API development, service integration, and microservices architecture.

Familiarity with Docker containerization, basic understanding of Kubernetes is a plus.
