À propos de cette offre

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 outcomes.

In 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:

Own and evolve enterprise agent frameworks and reference architectures (orchestration, tool/function calling, workflow integration, memory/state and retrieval/grounding) with clear boundaries, escalation rules and hand-off guidance

Build and maintain an "Agent Factory" of reusable components and blueprints (agent templates, tool adapters, prompt modules, evaluation harnesses and golden conversations) to accelerate Domain Pod delivery and maximise reuse across Sunrise

Define and implement agent safety layers, guardrails, policy enforcement, constrained tool access, bounded autonomy and human-in-the-loop approval/override patterns, and contribute to red-teaming, abuse testing and robustness testing

Define prompt standards and libraries; engineer prompts and system instructions for grounding, tool use, structured outputs and safe behaviour; enforce strict versioning, peer review, regression testing and change control

Design multilingual (DE/FR/IT/EN) customer and operational conversation flows with tone/style guidance, recovery paths and escalation patterns aligned to company guidelines and regulatory requirements

Partner with engineering teams to integrate agents into enterprise channels and workflows by defining tool schemas, authorisation checks, error handling, state management and full end-to-end observability (traces, logs and evaluation telemetry)

Define release readiness criteria (quality thresholds, safety checks, monitoring coverage, rollback/kill switch, runbooks) and support Pods through go-live, hypercare and post-implementation reviews

Monitor and continuously improve production behaviour (quality, grounding/hallucination risk, task success, escalation/containment and cost/latency), support incidents/postmortems and coach embedded specialists for systematic iteration

YOUR SKILLS:

Bachelor's/Master's degree in HCI, Engineering, Computer Science, Cognitive Science, Linguistics, Data/AI, Interaction Design or equivalent practical experience

Hands-on experience building and shipping conversational AI and agentic workflows (tool calling, grounding/RAG, multi-step workflows, structured outputs)

Strong prompt engineering and conversation design skills, including multilingual experience (DE/FR/IT/EN) and UX-oriented dialogue design

Practical experience with systematic evaluation (rubrics, golden sets), prompt/agent regression testing and disciplined versioning/change control

Working knowledge of modern LLM patterns (function/tool calling, structured outputs, retrieval/grounding, context management and reliability techniques)

Experience designing safety and privacy controls (guardrails, bounded autonomy, HITL, PII handling, policy compliance) and collaborating with governance, security, privacy and risk functions

Experience partnering in cross-functional product teams and matrixed Hub-and-Spoke delivery environments; ability to coach others through reusable patterns

Experience with production operations for AI solutions: observability/telemetry, monitoring/alerting, incident response and continuous quality improvement

Business-fluent English required; German is an advantage depending on stakeholder scope

At Sunrise, you'll be working in a dynamic and multinational environment where every voice is heard, perspectives are shared and values are lived. Diversity isn't just a program for us, it's part of our DNA. By celebrating our differences, we achieve great things together.

Sunrise has partnered with «Advance - Gender Equality in Business». We've also been awarded the Swiss LGBTI label and «Fair-ON-Pay Advanced» certification as recognition for offering all our employees equal pay for work of equal value.
