Senior LLM Researcher - Alignment

For one of our clients, we are looking for a Senior LLM Researcher - Alignment to help build reliable, safe, and high-performing language models.

In this role, you will design and implement alignment, sanitization, evaluation, and guardrailing pipelines that enable the delivery of trustworthy AI at scale. You will also play a key role in advancing Arabic-focused language model capabilities, including dialectal coverage and culturally relevant safety considerations.

Key Responsibilities

• Own alignment strategies, including:
  • Supervised fine-tuning (SFT)
  • Preference optimization, such as DPO and RLHF
  • Reward modeling
  • Rejection sampling
  • Constrained decoding
• Design and build end-to-end alignment pipelines covering data curation, training, preference optimization, and evaluation.
• Develop data pipelines for filtering, augmentation, preference-data collection, and quality control.
• Build model sanitization workflows, including:
  • PII removal
  • Data redaction
  • Prompt and response scrubbing
  • Harmful-pattern filtering
• Implement runtime guardrails using policy models, classifiers, rule engines, retrieval-based safety checks, and rate controls.
• Establish red-teaming and adversarial testing programs, including incident taxonomies and response playbooks.
• Define and maintain evaluation frameworks covering safety, robustness, task performance, drift, latency, and telemetry.
• Expand Arabic language coverage across dialects, domains, and culturally relevant safety scenarios.
• Partner with product, platform, and engineering teams to move research into production.
• Mentor engineers and researchers while developing internal documentation, playbooks, and best practices.
• Lead major AI initiatives that improve model helpfulness, harmlessness, faithfulness, reliability, and cost efficiency.
