Software Engineer (Java) - Remediation Agent

Recent breakthroughs in AI have made autonomous remediation a reality, but one major hurdle remains: Trust. Generative AI makes mistakes, and enterprises cannot automate what they do not trust. This is where you come in. As a Senior/Staff Engineer, you will architect the backend for Verified Autonomous Remediation, a sophisticated Agentic workflow that doesn't just generate code, but rigorously tests and validates it using Sonar's analysis engine. You will tackle the hard engineering problems required to close the "Trust Gap." \n

What You Will Do Daily:

• Build Features for the "Unified Remediation Engine". You will implement the backend logic that powers our remediation efforts. You will write clean, reliable code (Java/Python) that routes requests between deterministic QuickFixes and LLM agents, ensuring features are delivered reliably within our existing framework.
• Implement Production-Grade Agent Logic. You will take concepts from the Research team and "productionize" them. You will write the specific workflows that allow the Agent to read CI/CD errors, attempt fixes, and iterate until the build is green.
• Own Your Code from Local to Cloud. You are responsible for the full lifecycle of the features you build. You will deploy your services to AWS, monitor their health (metrics/logs), and troubleshoot production issues to ensure high availability for our users.
• Secure & Optimize Execution. Working within our existing sandboxing framework, you will implement the runners and isolation layers required to execute AI-generated code safely. You will ensure your implementation is secure and efficient.
• Collaborate & Share Knowledge. You will be an active member of the squad, reviewing PRs, documenting your work, and sharing knowledge with peers. You will act as a subject matter expert for the specific components you own, ensuring the team moves forward together., * 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.

• Solid Backend Engineering (3+ years). You have a track record of building and maintaining backend systems. You write clean, testable code and care about software craftsmanship.
• Polyglot Versatility (Java & Python). You are comfortable with one of the core languages: Java (for integration with the Core Sonar ecosystem) or Python (for AI/Agent logic). You pick up new tools and syntax quickly.
• Cloud Operations (AWS). You understand how your code runs in the cloud. You have experience with AWS (Lambda, ECS, or similar) and are comfortable with deployment pipelines, logging, and basic infrastructure monitoring.
• Systems Fundamentals. You understand how different services talk to each other (REST, queues, async processing). You know how to debug a distributed system when things go wrong.
• Interest in AI/LLMs. You are excited about the potential of AI in software development. Experience using LLM APIs (OpenAI/Anthropic) is a plus, but a willingness to learn how to integrate them into backend workflows is essential.
• Ownership Mindset. You don't just "take tickets." You own the delivery of your tasks, raising risks when necessary and ensuring your work meets high quality standards before it reaches production.

• We encourage usage of our robust time-off allocations with 27 PTO days for our employees based out of the Geneva region, plus additional days based on seniority and circumstances.
• We contribute 60% of the total cost for your pension; 13.5% to 15.5% of your base salary for savings; 2% for risk.
• Generous discretionary Company Growth Bonus, paid annually.
• Commuting: Sustainable mobility options, including carpooling and the refund of 60% of the annual transportation subscription.
• Global workforce with employees in 20+ countries representing 35+ unique nationalities.
• We have an annual kick-off somewhere in the world where we meet to build relationships and goals for the company.
