Requirements

• Minimum 8 years of backend engineering experience at product-based organisations, including real startup experience.
• Strong hands-on experience building production services in Go.
• Ability to design PostgreSQL databases, debug queries, and resolve performance issues.
• Experience shipping a customer-facing product that uses LLMs to make judgments, beyond a prototype or demo.
• Experience owning a service or feature end to end, including reliability and production issues.
• Ability to turn unclear customer problems into working solutions independently.
• Regular use of AI tools to build products and write clean, maintainable code.
• Experience working close to users and improving products through customer feedback.
• A public GitHub profile, side project, or technical blog is a strong plus.
• Candidate currently working at a product based organisation is a must.

Responsibilities

• Build and improve customer-facing features in a multi-tenant Go and PostgreSQL backend.
• Connect data sources such as CRMs, conversations, and support systems to produce reliable account intelligence.
• Build AI workflows that analyse information, take permissioned actions, and maintain an auditable record.
• Decide what an LLM should judge and what application code should calculate and store.
• Make workflows safe to rerun and detect drops in output quality.
• Keep features reliable and responsive across workspaces with 100 to 100,000 accounts.
• Support production operations across AWS, Docker, enterprise, and on-premise deployments.

In the first 30 days, learn the system by shipping 2–3 fixes a week and 1–2 improvements to existing features. Within 3–6 months, own a major new capability, from an unclear request to a feature customers use regularly. Potential areas include intelligence pipelines, CSM agents, renewal automation, and expansion signals.
