Job description

Hadl is an AI lab building the future data products and services for biology, manufacturing and aquaculture. We build agentic systems, data and diagnostic tools for our industry partners, working with the leading companies in our industries of focus to change the fabric of how work and decisions are made tomorrow.

Our team are engineers, industry experts, computer vision scientists and data passionate people, with cornerstone products that help farmers, processors, and companies building technology at the edge of the frontier.

Our work sits at the intersection of biology, data, and real world operations. We move fast, test often, and focus on practical impact. You will work closely with engineers, biologists, and product teams to turn complex data into reliable systems.

We collaborate openly, learn continuously, and value ownership. No rigid hierarchies. Curious people solving hard problems together.

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.

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.
