AI Engineer

Responsibilities

• Design & Develop:
  Architect and implement end-to-end AI Agents and full-stack applications that automate complex business processes.
• Foundational Engineering:
  Build and maintain the core AI tech stack, including agent orchestration frameworks, vector database integrations, and RAG (Retrieval-Augmented Generation) pipelines.
• Cloud Orchestration:
  Oversee the deployment and management of scalable AI services, selecting and adapting infrastructure to meet stringent requirements for high availability, performance, and efficiency.
• Strategic Transformation:
  Act as a key contributor to Sonar’s AI transformation, identifying high-impact opportunities for agentic automation across different departments.
• Governance & Ethics:
  Collaborate with cross-functional teams to establish governance, security protocols, and best practices for AI development and data privacy.
• Full-Stack Ownership:
  Manage the entire lifecycle of internal tools, from backend logic and LLM prompt engineering to intuitive frontend interfaces for internal users.

• Full-Stack Expertise:
  Professional experience in full-stack development (e.g., Python, React, or similar modern stacks).
• AI Agent Mastery:
  Proven experience developing and deploying autonomous AI Agents using frameworks such as Lang Chain, Auto Gen, CrewAI, or similar.
• Automation Roots: A strong background in traditional automation development (e.g., scripting, workflow engines, or RPA) prior to the LLM era, demonstrating a deep understanding of logic-based systems.
• Cloud Proficiency:
  Hands‑on experience architecting and deploying production‑grade applications on any major cloud platform (AWS experience is highly recommended).
• Architectural Vision:
  Deep understanding of the specific architectures required for agentic workflows, including state management, tool‑calling, and memory systems.
• Data & AI
  
  Skills:
  
  Experience with vector databases (e.g., Pinecone, Weaviate), fine‑tuning (optional but preferred), and advanced prompt engineering.
• Collaborative Mindset:
  Ability to work with non‑technical stakeholders to define governance and translate business needs into technical requirements.
• Growth Mindset: A passion for staying at the forefront of AI research and a desire to continuously evolve your skill set.

• Our culture and mission set us apart. We have a dynamic work culture that values respect and kindness and embraces the right to fail (and get right back up again!).
• Great people make a great company. We value people skills as much as technical skills and strive to keep things friendly while still being passionate leaders in our domains.
• We have a flexible work policy that includes 3 days in‑office and 2 days work‑from‑home each week for those located near our office locations; some locations such as Dubai, India, Japan and Australia operate fully remotely.
• We have a growth mindset. We love learning and believe continuous education is critical to our success. In an ever‑changing industry, new skills are necessary, and we’re happy to help our team acquire them.
• As the leader in our field, our products and services are as strong as our internal team members.
• We embrace transparency with regular meetings, cascading messages and updates on the growth and success of our organization.

• Pension Scheme: 1st Pillar (Unterstützungskasse):
  Automatic, financed by Sonar, 3% of gross salary, an additional benefit in addition to your salary.
• Pension Scheme: 2nd Pillar (bAV):
  Voluntary, 15% contribution by Sonar from social security savings.
• We encourage usage of our robust time‑off allocations with 28 PTO days for our employees based out of the Geneva region, plus additional days based on seniority and circumstances.
• Sonar recognizes holidays on working calendar days. If the holiday date occurs on a Saturday, we will recognize the day on the preceding Friday. If the holiday date occurs on a Sunday, we will recognize the day on the following Monday.
• Public transport reimbursement of 60% for annual subscription.
• Global workforce with employees in 20+ countries representing 35+ unique nationalities.
• We have an annual kick‑off…
