We are looking for a Senior AI Engineer to join our ELS Backporting Research team.
The team is responsible for designing and building AI-driven tools that automate patch backporting and make it faster to deliver secure updates across multiple Linux distributions.
As a Senior Engineer, you will:
- Own key components such as the Patch Backporter library and benchmarking infrastructure
- Design cross-component solutions to previously unsolved problems in automated patching
- Integrate your solutions into our existing CI/CD and automation stack so they are used in production, not just in experiments
Responsibilities:
- Lead development of the Patch Backporter library:
- Design and evolve its architecture and abstractions
- Keep it clean, composable, and extendable for new models and techniques
- Design and lead major changes in patch backporting automation:
- Identify bottlenecks and weak points in current workflows
- Propose and drive cross-component improvements end-to-end
- Own and evolve benchmarking and evaluation infrastructure:
- Design metrics, datasets, and evaluation flows to measure backporter performance
- Automate benchmarks in CI and make results stable and comparable over time
- Integrate improvements into the existing automation stack:
- Plan and implement how backporter updates propagate into the broader automation ecosystem
- Work with CI/CD, services, and databases so changes are fully wired into production
- Accelerate iteration within the team:
- Build Python tools, CLIs, small services, and helpers that make experiments faster and cheaper
- Improve local dev setups, test harnesses, and engineering processes for research
- Collaborate and communicate:
- Work cross-functionally with other engineering teams to align on interfaces and integration points
- Write clear technical documentation, design docs, and experiment logs
- Mentor junior engineers and share knowledge on AI, infra, and tooling
To be successful, you should have:
- Education & Experience
- BSc or MSc in Computer Science, Engineering, or a related field
- 5+ years in software engineering as a developer, tech lead, or team lead
- Demonstrated ownership of complex systems or components (not just small features)
- AI & LLMs
- Hands-on experience integrating LLMs in real projects (OpenAI, Anthropic, etc.)
- Familiarity with common approaches such as RAG, CAG, agents, tool-calling, etc
- Software Engineering
- Strong Python skills, including:
- Asyncio / multithreading / multiprocessing concepts and usage
- Testing frameworks (pytest, unittest) and a solid testing culture
- Experience with database design and querying:
- PostgreSQL or another SQL database
- MongoDB or another NoSQL database
- Infrastructure & Tooling
- Experience with CI/CD tooling (Jenkins, GitLab CI, or similar), test automation, and containerization (Docker)
- Confident Linux CLI user
- Experience supporting or operating services on Linux/Unix VMs
- Willingness and desire to use AI development tools (e.g., Cursor) in day-to-day work
- Ways of Working
- Ability to take loosely defined problem statements and turn them into concrete plans (architecture, milestones, experiment design) with minimal supervision
- Strong written communication skills in English (design docs, experiment logs, clear merge requests)
- Published research or documented experimentation experience in any Computer Science topic
- Experience formulating and testing hypotheses (e.g., comparing models, algorithms, or system designs)
- Data analysis skills:
- Representing results via tables, plots, or dashboards
- Designing meaningful metrics for system performance and quality
- Basic knowledge of the C language (able to read patches, understand diffs and build issues)
- Regular usage of AI engineering tools (Cursor, WindSurf, aider, Claude Code, etc.)
What's in it for you?
- A focus on professional development
- Interesting and challenging projects
- Fully remote work with flexible working hours, that allows you to schedule your day and work from any location worldwide
- Paid 24 days of vacation per year, 10 days of national holidays, and unlimited sick leaves
- Compensation for private medical insurance
- Co-working and gym/sports reimbursement
- Budget for education
- The opportunity to receive a reward for the most innovative idea that the company can patent
