Senior AI Product Engineer

Apate.ai is building the future of autonomous fraud intelligence and disruption. Backed by Australian scientific research, we deploy advanced conversational AI agents across different channels that engage scammers in real time - wasting their time, extracting intelligence, and helping banks, telcos and governments disrupt fraud at the source. Our platform is already deployed with Tier-1 enterprises globally and we’re rapidly scaling across banking and telecommunications. This is a rare opportunity to join a venture-backed company tackling a global problem at the intersection of AI, cybersecurity and financial crime.

The Role

We're looking for an AI Engineer who combines deep technical fluency in large language models with a product-oriented mindset. You'll own the full lifecycle of AI-powered features — from problem discovery through architecture, implementation, deployment, and iteration based on real-world outcomes. This is a hands‑on role in a small, high‑autonomy team building production agentic systems at scale. You'll work across the stack: designing multi‑agent architectures, building platform primitives, shipping user-facing features, and running the infrastructure that powers it all.

What you’ll do

AI Systems & Multi‑Agent Architecture

• Design and implement production multi‑agent systems (orchestration, routing, memory, tool use)
• Build and maintain LLM pipelines — prompt engineering, RAG, fine‑tuning, guardrails
• Own evaluation frameworks: correctness, cost, latency, safety
• Select and integrate models (commercial APIs, open-source, self-hosted) based on task requirements

Product Mindset & Feature Ownership

• Own features end‑to‑end: from understanding user needs through to shipping and measuring outcomes
• Collaborate with product and design to scope MVPs, iterate rapidly, and validate hypotheses
• Make pragmatic trade‑offs between speed and quality — know when to ship and when to polish
• Drive technical decisions with user impact in mind, not just engineering elegance
• Contribute to product discovery: identify opportunities where AI can solve real problems

Full‑Stack Delivery

• Build web applications and APIs (TypeScript, Node.js, React)
• Design and evolve database schemas (PostgreSQL, ClickHouse)
• Deploy and operate services on Kubernetes and serverless platforms
• Write clean, tested, well‑documented code that others can maintain

Platform Engineering

• Build reusable AI platform primitives — agent runtimes, observability, shared tooling
• Design APIs and data contracts consumed by other services and teams
• Implement and maintain CI/CD pipelines, IaC (Terraform/Helm), and cloud infrastructure (AWS, Cloudflare Workers)
• Own reliability: monitoring, alerting, incident response for AI workloads

What You Bring

Must Have

• 4+ years shipping production software, with 2+ years focused on AI/ML systems
• Strong TypeScript and/or Python — you write idiomatic, production-quality code
• Hands‑on experience with LLM APIs (OpenAI, Anthropic, Bedrock, or equivalent)
• Experience building agentic workflows — multi‑step reasoning, tool use, state management
• ML and model tuning experience (SageMaker, Weights & Biases, Hugging Face)
• ML/LLMOps: ELT and data management for ML workflows, ML/AI evaluation, prompt versioning, A/B testing
• Cloud infrastructure experience (AWS preferred) — you can deploy what you build
• Product sensibility — you think about user outcomes, not just technical correctness

Nice to Have

• Kubernetes, Helm, Cloudflare Workers / Durable Objects, Terraform
• SIP and Voice applications (Kamilio, RTP, voice agents)
• Startup or founding‑engineer experience — you've built from zero

Why Join Us?

• Be part of a mission-driven team tackling global scam and fraud challenges, with big growth aspirations
• Flexible work arrangements (hybrid)
• Zero bureaucracy, real impact
• Work directly with founders and researchers from day one
• A role where performance is rewarded and impact is visible

Apate was crowned the Most Innovative Technology Company Australia by AFR and has won a host of other awards at the Australian AI Awards, Annual Fintech & Banking Awards and ARN Innovation Awards.
