About the Role

We are building the future of seafood supply chains with an industry-leading seafood company. You will be developing and owning architecture, infrastructure, integrations and data models.

This is a hands-on role. You will write code, set the standards and problem solve, as one of a small team of senior builders shipping a platform that more companies can plug into without a rewrite.

What You'll Do

• Design and build the architecture and data model for a multi-client platform, with a full audit trail and each client's data kept separate.
• Build integrations with the systems a business already runs, connecting before replacing, with clear error handling and alerting. No silent failures.
• Build roadmap features from design through to production.
• Own the infrastructure: cloud environments, CI/CD, networking, access control, security, monitoring and backups.
• Mentor and learn alongside passionate colleagues, and document what you build so the work never depends on one person.

What We're Looking For

• 4+ years of software engineering, building and shipping production systems.
• Experience designing, building and running production systems end to end: architecture, data model, deployment and operations.
• Strong in a typed backend language (TypeScript, Go or Python) and in SQL with PostgreSQL or similar.
• Experience building integrations with third-party systems through APIs, webhooks or file exchange.
• Experience owning cloud infrastructure on GCP or AWS: environments, CI/CD, containers, monitoring, security and access.
• Experience with multi-tenant design and audit trails.
• High standards for code quality, testing and review, including AI-assisted code.
• Fluent written and spoken English, and able to explain technical trade-offs clearly to non-technical people.
• Able to work from Surabaya for up to 2 weeks in every 6.

Nice to Have

• Experience in supply chain, logistics, retail or fintech.
• Shipped LLM-based features to production.
• Infrastructure as code (for example Terraform).
• Client-facing, consulting or agency experience.
• Fluent Bahasa Indonesia.

What We Offer

• Technical ownership of a new platform from day one.
• Real operations, real data, and users who rely on what you build every day.
• A small team of senior builders, with no layers between you and the problem.
• Fast iteration and direct impact on how an entire sector works.
• Equity participation for the right candidate.
