Agentic AI Engineer

Position: Agentic AI Engineer 80-100%
Location: Zürich

At Sunrise, we think bigger, go further and create new ideas. For us working culture means achieving great things together. It’s where respect and innovative ideas combine with real teamwork – every voice counts, every perspective makes us stronger. Our passion spurs us on to try new things and grow continuously. Sound like you? Then join our success story.

At ADAO (AI, Data and Agentic Enablement Office), we bring people together to unlock the future of Sunrise through data, analytics, AI, and agentic technologies. We think big, move with purpose, and turn ideas into real impact for our customers and teams. ADAO is where innovation meets trust: we build strong data foundations, scale safe and reliable AI capabilities, and empower business units through a hub‑and‑spoke operating model to deliver meaningful results across the company.

Within this model, you will work as part of the Agentic Enablement and Prompt Engineering & Conversation Design team, where the central hub provides standards, platforms, architecture, and best practices, while cross‑functional, outcome‑driven Pods are embedded in and led by the business. You will act as an engineering expert, partnering closely with the business to deliver on their priorities and  this role you will enable Sunrise to design, deploy and continuously improve production‑grade agentic and conversational AI solutions across customer and employee workflows.

You will provide shared frameworks, standards and quality gates to ensure AI behaviour is predictable, grounded in governed enterprise knowledge and data, safe, multilingual and operationally ready. You will partner with ADAO Domain Pods and engineering teams to accelerate delivery through reusable prompt/agent patterns, evaluation harnesses and disciplined release management.

YOUR CHALLENGE:

Agentic Systems Architecture:

Design and evolve enterprise agent frameworks including orchestration, tool/function calling, workflow integration, retrieval/grounding and state management

Develop reusable agent infrastructure (“Agent Factory”) consisting of modular agent templates, tool adapters, prompt modules, evaluation pipelines, and reference implementations to enable scalable and consistent deployment.

Engineer structured single-agent and multi-agent systems with clearly defined reasoning boundaries, escalation paths and autonomy levels

Define architectural patterns for distributed agent workflows across domains and business Pods Reliable LLM Engineering:

Implement reliability patterns for LLM-based systems including fallback strategies, structured output validation, deterministic routing and failure containment mechanisms

Optimize latency, token efficiency and cost-per-interaction while maintaining quality thresholds

Apply context management and grounding techniques to ensure predictable and auditable behavior

Prompt Engineering & Conversation Logic:

Engineer high-quality prompts and system instructions for safe, grounded and structured agent behavior

Define and maintain prompt libraries, versioning standards and regression testing practices

Design multilingual (DE/FR/IT/EN) conversational flows aligned with enterprise and regulatory standards

Evaluation & Quality Control:

Design and maintain evaluation harnesses including regression suites, golden conversations and structured scoring frameworks Define measurable acceptance thresholds and release readiness criteria

Monitor production behavior including grounding quality, hallucination risk, escalation patterns and performance metrics

Production Integration & Observability:

Integrate agentic systems into enterprise channels and backend services with robust authorization, state handling and error management Implement observability standards including traces, logs, telemetry and structured evaluation reporting Support go-live, hypercare and post-incident improvement cycles

Safety, Risk & Governance:

Implement bounded autonomy and human-in-the-loop control patterns

Enforce guardrails, policy compliance and PII protection mechanisms

Collaborate with Security, Privacy and Governance teams to ensure enterprise-grade compliance
