About the team

Concorde Systems is building the intelligence infrastructure for Indonesianindustry, starting with a Computerized Maintenance Management System thathelps industrial teams manage assets and heavy machinery, prevent downtime,and run maintenance operations end to end. We are currently running a liveenterprise pilot at a national plant.

The system you would work on is Concorde Station, our multi-tenant CMMS:organizations use it to track physical assets, run work orders andprocedures, manage parts inventory, and report on maintenance. Our firstpaying client is being onboarded this quarter.

About the role

This is a part-time contract, 20 hours per week from September throughDecember 2026, with the scope fixed before you start. The domain model isstrong: a polymorphic audit-event table, an atomic parts ledger, a workingforms state machine, and seventeen live domains. The system itself, however,is still a prototype: there is no test suite, no CI, and no deploymentpipeline yet. This contract exists to change that.

To set expectations, the role is not: ownership of the full roadmap, arewrite (the architecture is sound and stays), a move to microservices,Kubernetes, or an event bus, or a frontend rebuild (the design system iscomplete).

The stack is Go 1.25 with chi v5, pgx v5, and sqlc on PostgreSQL 16 atSupabase. There is no ORM and there will not be one: SQL is written by handand compiled to type-safe Go. The frontend is Next.js 14, TypeScript, andTailwind. CI/CD from scratch and Supabase operations can be learned on thego.

What you'll do

• Write the detailed specs together with us before you start
• Stand up the first CI pipeline and the first real test suite for the API
• Containerize the service and get a working staging-to-production deploy process running
• Wire up the RBAC checks that are already fully modeled in the database but enforced nowhere in code

What we're looking for

• Available and willing to work from September through December 2026 (contract)
• Real experience writing Go, including at least one HTTP service you personally deployed
• Comfortable with raw SQL
• Willing to set up a CI pipeline and a deployment process from scratch
• Able to read and reason carefully about authorization logic; carefulness matters more than years of experience
• Enough TypeScript to write a Next.js Server Action against an existing design system; no design work is involved
• A computer science or electrical engineering background
• Exposure to Supabase
• Anything you have shipped and kept alive past the demo

Compensation

This is a paid part-time position: Rp 7.200.000 per month for 20 hours perweek, negotiable and can be discussed.

Beyond the rate: access to premium AI coding tools (Claude), a real, liveproduction system to point to afterward, the opportunity to grow this into along-term partnership, an official certificate or letter of recommendation,hands-on experience building a real tech startup, access to startup networks,communities, and industry practitioners, and flexible onsite workspace accessin Bandung, remote friendly.
