Job Description
Why should I Apply:
At Sonar were a group of brilliant motivated and driven professionals working hard to help organizations build responsible secure highquality code quickly and systematically. We build solutions that dont just solve symptoms of problems we fix problems at the source source code to be specific.
We have a dynamic culture with employees worldwide and hub offices in the USA Switzerland the UK Singapore and Germany. We believe team members should have the opportunity to come to work every day work on a product they are proud of love what they do and feel energized by their peers. With our roots deep in the open source community were all about the mission: provide solutions that deliver Clean Code.
The impact you can have
The Sonar Code Next team is looking for a passionate Python Developer to join a fastpaced dynamic group at the intersection of Large Language Models (LLMs) static analysis and programming languages. Working on cuttingedge AIdriven projects youll help push the boundaries of automated code quality and security.
Our mission is to harness our expertise in static analysis and large language models (LLMs) to advance AIs ability to understand generate and improve code. We develop prototypes grounded in cuttingedge research testing innovations across the LLM development lifecyclefrom data processing and model training to benchmarking. Our approach leverages techniques such as supervised finetuning (SFT) direct preference optimization (DPO) reinforcement learning from human feedback (RLHF) and retrievalaugmented generation (RAG) to enhance model performance and code quality.
As a key member of this team youll directly influence AIdriven solutions by developing and refining the tools that make these initiatives possible. In this handson role youll focus on implementing and optimizing methodologies that enhance code qualityensuring that all solutions are scalable maintainable and ready for production.
On a daily basis you will
- Develop and maintain Pythonbased tooling and infrastructure to support AIdriven solutions for code quality and security.
- Implement and optimize AIfocused experiments creating robust systems to evaluate modern techniques including finetuning retrievalaugmented generation (RAG) direct preference optimization (DPO) and reinforcement learning from human feedback (RLHF).
- Write scalable productionquality Python code to support AI workflows dataset processing and evaluation frameworks.
- Design and maintain benchmarking pipelines to assess Large Language Model (LLM) performance in generating clean maintainable code.
- Process and refine datasets ensuring theyre structured and optimized for training and evaluation.
- Develop integrations between AI systems and static analysis tools enabling AIassisted insights for developers.
- Collaborate with static analysis experts and AI researchers to turn experimental ideas into practical working solutions.
- Ensure the scalability reliability and maintainability of AI tooling as it transitions from experimentation to production.
- Continuously improve the development processes via workflow refinement automation and tooling for AIassisted coding.
- Work in a fastpaced iterative environment that bridges researchdriven innovation with realworld software development.
The Skills You Will Demonstrate
- Proven expertise in Python development writing clean maintainable and efficient code.
- Solid software engineering foundation including algorithms testing CI/CD and best practices for building scalable and reliable software.
- Deep curiosity about LLMs static analysis and multiple programming languages recognizing their strengths challenges and nuances.
- Genuine interest in AIdriven software development and a willingness to work on projects integrating AI with developer tools.
- Pragmatic approach to problemsolving balancing researchdriven innovation with building productionready systems.
- Selfdriven mindset bold enough to challenge the status quo yet humble and open to learning and feedback.
