Job description

We are building a next-generation AI onboarding agent for software companies.

The role is based in Bali and we can offer a relocation package for the right candidate. The role will start as a contractor with a view to it moving full-time depending on performance.

AI-first SaaS product where product quality, UX polish, and AI behaviour are tightly coupled. Our core engineering team is focused on shipping critical user-facing functionality and AI capabilities.

What’s missing is clear ownership of the systems that determine whether something is safe to ship — analytics, internal tooling, product quality gates, and AI evaluation infrastructure.

This role exists to own that entire “release readiness” layer end-to-end, enabling the team to move fast without breaking product quality or AI experience.

Tasks

You will be the single owner of our product platform and release-quality systems.

• Product analytics & instrumentation
• Define and maintain a consistent event schema
• Implement analytics across frontend, backend, and AI agents
• Build internal dashboards for funnels, usage, drop-offs, and failures
• Internal & admin tooling
• Build dashboards and tools for debugging sessions and inspecting AI behaviour
• Replace ad-hoc scripts and database queries with reliable internal systems
• Product quality & release systems
• Own feature flags, rollouts, and release checks
• Define what is “shippable” for non-trivial changes
• Act as a release gate owner, with authority to block unsafe releases
• AI quality & evaluation
• Version and manage prompts and AI configuration changes
• Define when AI evals are required before shipping
• Build and maintain AI evaluation pipelines and make results visible over time
• Platform health & evolution
• Define system-level health and reliability metrics
• Establish expected variance vs unacceptable deviation for AI systemsReduce platform-level debt that slows shipping and decision-making

Requirements

Required technical stack

• Strong full-stack fundamentals
• Testing & CI: pytest; vitest; Playwright (or equivalent) for E2E and behavioural testing, GitHub CI/CD gate design
• Data & Systems: Distributed and asynchronous systems, PostgreSQL
• Cloud & Security: AWS logging and metrics (e.g. CloudWatch), Baseline application security testing, Familiarity with common API, auth, and WebSocket risks, OWASP ZAP or equivalent tooling
• AI / Agent systems experience:
• Experience testing AI-, agent-, or other non-deterministic systems
• Familiarity with behavioural regression detection (not brittle assertions)
• Understanding why deterministic testing breaks down — and how to design around it
• Experience with LLM or agent observability tools (e.g. LangSmith) is a strong plus
• Experience with vision or multimodal systems is a strong plus
• Experience with real-time systems (voice, streaming, WebSocket) is a strong plus

What we’re looking for

• At least 4 years of experience in platform, quality, or reliability-focused roles
• Strong system-level thinking (not just test scripts)
• Experience testing AI or agent-based systems
• Understands why deterministic testing is hard — and how to work around it
• Comfortable turning vague problems into clear, shipped systems
• Willing to make and defend platform-level decisions
• Strong product judgement and pragmatism

Nice to have

• Experience designing internal platforms used by other engineers
• Exposure to ISO / SOC / enterprise readiness environments
