Jobbeschreibung

Who is Sonar

Sonar helps prevent code quality and code security issues from reaching production, amplifies developers' productivity with AI assistants, and improves the developer experience with streamlined workflows. Sonar analyzes all code—whether written by your internal team, genAI, or third parties—resulting in more secure, reliable, and maintainable applications. Rooted in the open source community, Sonar’s solutions support over 30 programming languages, frameworks, and infrastructure technologies. Today, Sonar is used by 7M developers and 400K organizations worldwide, including the DoD, Microsoft, NASA, MasterCard, Siemens, and T‑Mobile.

We believe in developing great products that are supported by great internal teams and a strong culture. We are highly committed to, obsessed with, deliberate, effective, and efficient—operating as one team to accomplish our goals. At Sonar, CODE is more than just an acronym—it’s a mindset that defines daily operations.

Why You Should Apply

We’re a group of brilliant, motivated, and driven professionals working hard to help supercharge developers to build better, faster. Sonar helps continuously improve code quality and code security while reducing developer toil, allowing developers to focus on what they love and less on what they don’t. Our solutions don’t just treat symptoms; we fix issues at the source for all code, whether developer‑written, AI‑generated, or from third parties.

The Impact You Will Have

As AI Engineer, you will be a driving force in Sonar’s AI transformation, solving internal business operation problems, automating complex processes, and amplifying productivity across departments using cutting‑edge AI agents and full‑stack tools. Your work will directly enhance our operational efficiency and strategic agility.

What You Will Do Daily

• Design & develop end‑to‑end AI agents and full‑stack applications that automate complex business processes.
• Build and maintain the core AI tech stack, including agent orchestration frameworks, vector database integrations, and RAG pipelines.
• Oversee cloud deployment and management of scalable AI services, selecting and adapting infrastructure for high availability, performance, and efficiency.
• Identify high‑impact opportunities for agentic automation across departments as part of Sonar’s AI transformation.
• Collaborate with cross‑functional teams to establish governance, security protocols, and best practices for AI development and data privacy.
• Own the entire lifecycle of internal tools—from backend logic and LLM prompt engineering to intuitive frontend interfaces for internal users.
• Guide junior engineers and contribute to a culture of technical excellence in AI and automation.

The Experience You Will Need

• 5+ years of professional full‑stack development experience (Python, Node.js, React, or similar).
• Proven experience developing and deploying autonomous AI agents using LangChain, AutoGen, CrewAI, or similar frameworks.
• Strong background in traditional automation (scripting, workflow engines, RPA) prior to the LLM era.
• Hands‑on experience architecting and deploying production‑grade applications on major cloud platforms (AWS preferred).
• Deep understanding of agentic workflow architectures (state management, tool‑calling, memory systems).
• Experience with vector databases (Pinecone, Weaviate), fine‑tuning (optional), and advanced prompt engineering.
• Ability to work with non‑technical stakeholders to define governance and translate business needs into technical requirements.
• Passion for staying at the forefront of AI research and a desire to continuously evolve your skill set.

Why You Will Love It Here

• Dynamic work culture that values respect, kindness, and resilience.
• Great people and a focus on technical and interpersonal skills.
• Flexible work policy: 3 days in‑office and 2 days WFH per week near office locations; some locations fully remote.
• Growth mindset with support for continuous learning and skill development.
• Strong leadership and deep industry expertise.
• Transparency through regular meetings, cascading updates, and growth discussions.

Benefits of Working with Sonar

• Pension Scheme: 1st Pillar (Unterstützungskasse) – 3% of gross salary, financed by Sonar.
• Pension Scheme: 2nd Pillar (bAV) – 15% contribution by Sonar from social security savings.
• 28 PTO days for Geneva region employees, with additional days based on seniority and circumstances.
• Public transport reimbursement of 60% for annual subscription.
• Global workforce in 20+ countries with 35+ unique nationalities.
• Annual worldwide kick‑off event to build relationships and set company goals.
