Cognigy AI Architect

Natilik is a global technology solutions and services provider. Our mission is two-fold: growing a brand that is seen as the industry’s “Confident Guide” and building a business with a balanced purpose. We want to be a “Confident Guide”, sat between the vendors, who make technology, and our clients who want to use it to help deliver the outcomes most important to them. We offer solutions, services, platforms, applications and expertise to help.

The Role

Our Cognigy AI Architect owns the overall solution design, architecture, design standards, integration strategy, security approach, platform patterns, technical governance, conversation design approach, and design sign-off. The AI Architect may also be required to undertake or support AI Engineer responsibilities where necessary. These include implementing the agreed design, testing and debugging, maintaining documentation, and escalating any issues where the design is unclear, presents risks, is incomplete, or is blocked.

Why this role matters: Our Cognigy AI Architect ensures the solution is not just functional, but scalable, secure, maintainable, testable, and suitable for production voice and chat use cases. This role should provide the technical and conversational design clarity that allows our Cognigy AI Engineers to deliver confidently and consistently.

Key Responsibilities:

• Own the end-to-end Cognigy solution design across the assigned use cases.
• Define the architecture, design patterns, flow structure, agentic AI strategy, tool-calling approach, integration model, security controls, guardrails, multilingual approach, voice experience, xApp strategy, reporting model, and production readiness standards.
• Decide when to use agentic AI, deterministic flows, NLU, Knowledge AI, xApps, or human handover.
• Define reusable patterns for LLM Prompt nodes, tool schemas, Resolve Tool Actions, context management, API integrations, fallback handling, escalation, and error recovery.
• Provide technical direction to Cognigy AI Engineers, review implementation quality, unblock delivery issues, validate design decisions, and own solution sign-off.
• Lead stakeholder workshops, demos, design reviews, risk reviews, and technical governance.

Essential skills:

• At least 2–3 years’ experience designing and delivering conversational AI, voice AI, or agentic AI solutions.
• Strong hands‑on Cognigy AI architecture and delivery experience, including Flows, Voice Gateway, Agentic AI tool calling, LLM Prompt nodes, Knowledge AI, xApps, Playbooks, Insights, environment management, and reusable solution patterns.
• Strong practical understanding of LLM prompting, tool design, tool orchestration, structured tool results, hallucination prevention, prompt grounding, guardrails, and when to use deterministic logic or NLU alongside agentic reasoning.
• Good working knowledge of conversation design principles, including intent journeys, task flows, fallback paths, repair prompts, turn‑taking, escalation points, voice‑friendly wording, and reducing customer friction.
• Strong JavaScript understanding for reviewing Code Nodes, validation logic, payload mapping, API response handling, context manipulation, logging, and custom flow behaviour.
• Experience designing secure REST API integrations, PII‑safe handling, authentication patterns, error handling, observability, and production support models.
• Strong voice‑agent architecture experience, including STT/TTS selection, multilingual recognition, DTMF, barge‑in, end pointing, transfers, hang‑up logic, silence handling, latency, and speech tuning.
• Ability to debug complex issues using transcripts, context, input, tool arguments, Voice Gateway logs, API responses, Insights, and Code Node logs.

Desirable skills:

• Cognigy certification; advanced conversation design or voice UX experience, including persona design, tone‑of‑voice definition, dialogue repair strategy, multilingual copy design, IVR‑to‑voice‑agent migration, containment optimisation, and usability testing.
• Contact‑centre architecture experience.
• Agent Copilot and Cisco Finesse integration experience.
• SSML and advanced TTS tuning.
• SIP/WebRTC, Twilio or similar voice connectivity.
• CRM, case‑management, or CCaaS integrations.
• Experience defining guardrail frameworks for prompt leakage prevention, scope control, profanity filtering, hallucination prevention, and speech‑safe output.
