Job Description

We are seeking a new colleague to drive the design and delivery of advanced AI solutions across our organization. This is a senior individual contributor role focused on impactful technical execution, cross‑organizational influence, and hands‑on development of enterprise‑grade AI products.

Our AI Engineering team supports key business domains while shaping analytic and AI capabilities across the company. You will work alongside AI engineers, data scientists, product managers, and domain experts to build reliable, scalable AI systems and help elevate the organization’s AI literacy and adoption.

This role is ideal for someone who excels as a deep technical contributor, systems thinker, and collaborative problem solver without direct people‑management responsibilities.

What Will You Do?

Technical Impact & Execution:

• Architect, design, and implement robust and scalable AI systems, including generative AI and RAG‑based solutions

• Lead complex AI development workstreams end‑to‑end as a senior technical contributor

• Build high‑quality, maintainable code and champion engineering best practices across the team

• Select and integrate appropriate language models, vector databases, retrieval strategies, and evaluation frameworks

• Optimize and fine‑tune models for performance, reliability, security, and responsible AI use

• Drive continuous experimentation and refinement of RAG pipelines, prompt strategies, and model‑driven workflows

Cross‑Functional Collaboration:

• Work closely with tech leads, data scientists, platform teams, and SMEs to define requirements and translate them into production-ready AI solutions

• Influence decision‑making through clear communication of findings, risks, trade-offs, and solution recommendations

• Support adoption of AI products by collaborating with business stakeholders and technical partners

Thought Leadership & Strategy Contribution:

• Serve as a senior AI expert who uplifts engineering maturity across teams through technical guidance—not line management

• Contribute to shaping our long-term AI engineering patterns, architectural standards, and operational best practices

• Evaluate emerging AI technologies and recommend their responsible application in the enterprise context

• Advocate for excellence in observability, MLOps, reliability, and lifecycle management of AI systems

Ways of Working:

• Actively participate in Agile ceremonies and support planning of technical work

• Influence technical prioritization and contribute to roadmap discussions

• Maintain high standards of documentation, testing, and monitoring for all AI components

Technical Expertise:

• Expert-level Python skills and deep experience building modern AI/ML pipelines

• Strong experience designing, implementing, and scaling AI solutions with cloud services, data pipelines, databases, APIs, and modern engineering tooling

• Hands-on experience with RAG systems, LLMs, vector databases, prompt engineering, and generative AI applications

• Solid understanding of ML fundamentals (deep learning, optimization, evaluation, monitoring)

• Experience with CI/CD, MLOps, automated testing, and model observability

• Ability to design and build RESTful APIs for AI-driven services

Collaboration & Communication:

• Excellent communication skills with the ability to translate technical concepts for diverse audiences

• Demonstrated ability to influence stakeholders and guide technical direction without formal authority

• Strong analytical and problem‑solving skills; comfortable managing ambiguity
