Tech Lead (ARIP- Platform) - CP Axtra

Senior technical leader and architectural owner for ARIP Layers 2–4: Semantic Fabric (KGIP consumption from DEAA), Decisioning (ARIP-side D-01/D-04/D-11–13), and Agent Runtime (LangGraph / CrewAI, HITL gates, Trust Gate Framework, observability). Co-chairs the Architecture Review Board. Leads 5–6 ICs including 2 AI Engineers and 1 ML Engineer.

Remote candidates outside of Thailand are welcome to apply.

Key Responsibilities:

• Own Layer 2–4 reference architecture; co-chair Architecture Review Board (fortnightly) with Head of ARIP; author ADRs for D-004 (KG build/buy), D-005 (agent framework), D-006 (LLM provider)
• Build and own Agent Runtime (Layer 4): framework deployment, Trust Gate Framework (Shadow → Recommender → Executor), Agent Registry, HITL gates, OpenTelemetry + Langfuse observability
• Finalise KGIP consumption contract with DEAA: KG access, Semantic Layer API, Data Product Catalogue subscription, Event Stream ingestion
• Build Layer 3 ARIP-side decisioning: D-01 Decision Orchestrator, D-04 Trust Gate Service, D-11/D-12/D-13 agent-side helpers; consume DEAA's LLM Gateway (D-02) and Vector Search (D-03)
• Own per-agent cost meter, Layer 4 SLOs (P95 invocation, success rate, HITL response time), and incident response for runtime failures
• Lead and mentor 5–6 ICs (platform-side Senior SWEs, 2 AI Engineers, 1 ML Engineer) on agent engineering discipline and eval-driven development

Requirements

• 8+ years software engineering; 3+ years as Tech Lead / Staff owning platform standards with architectural decision authority
• Production multi-agent orchestration with HITL gates and eval-driven CI — LangGraph / CrewAI / AutoGen or equivalent (not just RAG demos)
• Expert with at least one major LLM provider (Azure OpenAI / Anthropic / Bedrock / Vertex) in production with cost and latency optimisation
• Strong distributed systems, observability (OpenTelemetry, Langfuse), and API-first service contract discipline
• Knowledge graph or semantic-layer production experience preferred (KGIP consumption design requires it); ADR authorship and ARB facilitation at senior level
• Calibre: Staff/Principal Engineer from Agoda, Grab, Shopee, AI-native startups (Anthropic-adjacent) with multi-agent production experience
