Job description

About SMS Perkasa

We're an innovative steel and building materials distributor based in Surabaya, transforming how the industry operates through technology. While others in the steel trade rely on spreadsheets and phone calls, we build software that gives us — and our customers — a real edge.

The Role

You won't just write code here. You'll steer AI agents that write code, then make sure it's actually good. We use AI coding tools daily — not as novelties, but as core parts of how we ship software. Your job is to define the problem clearly, direct AI to build the solution, review every line it produces, and own what goes to production.

What You'll Do

• Break down business problems into clear specs and architectural prompts that guide AI agents toward correct solutions
• Direct AI coding tools to generate, test, and iterate on code across our systems — from internal platforms to customer-facing products
• Design system architecture — APIs, databases, integrations — and make decisions that hold up as we scale
• Own features end-to-end: from understanding the business need, through implementation, to production deployment
• Write tests that keep AI agents (and yourself) honest. Strong test coverage is how you move fast without breaking things
• Collaborate directly with our team to translate real operational challenges in the steel industry into working software

What We Offer

We're a young team that builds things that matter — tools that impact how steel and building materials move across Indonesia. You'll have real freedom to explore ideas and make your own decisions. No one here is going to micromanage you.

Come with your bright ideas. Speak up. Challenge assumptions. That's how we work.

We invest seriously in learning — new tools, new skills, personal growth. You'll never stop getting better here. And you'll be part of a team that genuinely values your contributions and has fun doing the work.

We offer competitive compensation and benefits, because that's what good people deserve.
