AI​/LLM Evaluation & Alignment Software Engineer

AI/LLM Evaluation & Alignment Software Engineer

Join to apply for the AI/LLM Evaluation & Alignment Software Engineer role at Leo Tech
.
At Leo Tech, we are passionate about building software that solves real-world problems in the Public Safety sector. Our software has been used to help the fight against continuing criminal enterprises, drug trafficking organizations, identifying financial fraud, disrupting sex and human trafficking rings and focusing on mental matters to name a few.

Role

• Remote, WFH.

• As an AI/LLM Evaluation & Alignment Engineer on our Data Science team, you will design and implement evaluation frameworks, guardrails, and bias-mitigation strategies that give our customers confidence in the reliability and ethical use of our AI systems. This is an individual‑contributor (IC) role that combines hands‑on technical engineering with a focus on responsible AI deployment. You will work closely with AI engineers, product managers, and Dev Ops teams to establish standards for evaluation, design test harnesses for generative models, and operationalize quality assurance processes across our AI stack.

Core Responsibilities

• Build and maintain evaluation frameworks for LLMs and generative AI systems tailored to public safety and intelligence use cases.

• Design guardrails and alignment strategies to minimize bias, toxicity, hallucinations, and other ethical risks in production workflows.

• Partner with AI engineers and data scientists to define online and offline evaluation metrics (model drifts, data drifts, factual accuracy, consistency, safety, interpretability).

• Implement continuous evaluation pipelines for AI models, integrated into CI/CD and production monitoring systems.

• Collaborate with stakeholders to stress test models against edge cases, adversarial prompts, and sensitive data scenarios.

• Research and integrate third‑party evaluation frameworks and solutions; adapt them to our regulated, high‑stakes environment.

• Work with product and customer‑facing teams to ensure explainability, transparency, and auditability of AI outputs.

• Provide technical leadership in responsible AI practices, influencing standards across the organization.

• Contribute to Dev Ops/MLOps workflows for deployment, monitoring, and scaling of AI evaluation and guardrail systems (Kubernetes experience a plus).

• Document best practices and findings, and share knowledge across teams to foster a culture of responsible AI innovation.

What We Value

• Bachelor’s or Master’s in Computer Science, Artificial Intelligence, Data Science, or related field.

• 3–5+ years of hands‑on experience in ML/AI engineering, with at least 2 years working directly on LLM evaluation, QA, or safety.

• Strong familiarity with evaluation techniques for generative AI: human‑in‑the‑loop evaluation, automated metrics, adversarial testing, red‑teaming.

• Experience with bias detection, fairness approaches, and responsible AI design.

• Knowledge of LLM observability, monitoring, and guardrail frameworks (Langfuse, Langsmith).

• Proficiency with Python and modern AI/ML/LLM/Agentic AI libraries (Lang Graph, Strands Agents, Pydantic AI, Lang Chain, Hugging Face, PyTorch, Llama Index).

• Experience integrating evaluations into Dev Ops/MLOps pipelines, preferably with Kubernetes, Terraform, ArgoCD, or Git Hub Actions.

• Understanding of cloud AI platforms (AWS, Azure) and deployment best practices.

• Strong problem‑solving skills, with the ability to design practical evaluation systems for real‑world, high‑stakes scenarios.

• Excellent communication skills to translate technical risks and evaluation results into insights for both technical and non‑technical stakeholders.

Technologies We Use

• Cloud &

Infrastructure: AWS (Bedrock, Sage Maker, Lambda), Azure AI, Kubernetes (EKS), Terraform, ArgoCD.

• LLMs & Evaluation:
