Responsibilities

As part of the R&D Automation team, you’ll focus on:

• Agentic software development: building AI agents that automate and augment workflows across the entire software development lifecycle.
• AI platforms and capabilities: creating reusable foundations, tools and integrations that allow agents to interact effectively with our codebases, engineering systems and internal knowledge.
• Experimentation at speed: rapidly prototyping new approaches, measuring their effectiveness and scaling the ones that create meaningful value.
• Safe and reliable automation: designing the right verification, context and human-in-the-loop mechanisms so agentic workflows can be adopted with confidence.

Requirements

• Extensive experience (~8 years) designing and building complex backend software systems.
• Strong software engineering skills with production experience using Python.
• Hands-on experience building AI agents, agentic workflows or platforms that enable others to build and use AI-powered capabilities.
• Strong understanding of modern agentic AI patterns, including context management, tool use, orchestration and evaluation/verification.
• Experience integrating AI systems with APIs, MCPs, internal tools, codebases and other engineering systems.
• Experience taking new technical ideas from experimentation or proof of concept into robust, scalable solutions.
• A strong experimentation mindset: comfortable working with ambiguity, iterating quickly and using data and feedback to determine what works.
• Good understanding of distributed systems and the backend architecture required to operate AI-powered systems reliably.
• Strong product thinking, with the ability to understand user workflows and connect technical solutions to measurable outcomes.
• Strong communication skills. Minimum C1 English level.
