What you'll do
- Develop autonomous AI agents that handle a complete recruitment process, from sourcing to candidate qualification and a documented shortlist.
- Improve the voice AI's fluency and naturalness by working on latency, turn-taking and robustness to accents and noisy environments.
- Build intelligent analysis tools that exploit recruiter-candidate exchanges, generate reports and provide real-time assistance.
- Design and train ML models for scoring, classification and probabilistic modeling together with psychometricians.
- Ensure quality and reliability by selecting approaches, building evaluation frameworks and measuring performance, fairness and robustness.
- Industrialize and evolve AI solutions, deploying and monitoring systems with the MLOps team and sharing findings.
What we're looking for
- Confirmed experience in ML Engineering, with AI models and systems personally contributed to and deployed in production.
- Mastery of modern, typed, asynchronous Python and software engineering best practices, end-to-end ML development.
- Comfort with the AWS ecosystem, notably SageMaker, Lambda and Kubernetes.
- Experience in voice AI (ASR, TTS) or real-time conversational agents.
- Ability to design and evaluate AI agents or complex systems, exploring foundation models and agentic architectures.
- Solid statistics foundations, notably probabilistic modeling, calibration and rigorous model evaluation.
- Ability to explain and defend technical choices to non-technical audiences and enjoy working with complementary expertise.
- Curious, pragmatic and sensitive to AI's impact on people, able to balance innovation, performance and reliability.
- Daily use of AI tools (Claude, ChatGPT, Gemini or equivalents) with a critical eye on results.
Nice to have
- Experience in causal inference, experimentation or fairness in ML is a real plus.
