Mission Statement & Summary
We're hiring a Senior AI Engineer to design and deliver AI systems across the business.
This is a hands-on role focused on building production-grade solutions using LLMs and agentic systems, embedding AI directly into core business processes rather than building isolated prototypes. You'll take high-value problems and turn them into scalable, reliable systems used in real workflows, driving measurable business outcomes.
You'll contribute significantly to technical direction, architecture, and implementation, translating defined business priorities into robust, production-ready systems. You'll make key technical contributions and work hands-on alongside engineers to deliver solutions that are reusable, scalable, and built for long-term impact.
How You'll Contribute
Design and implement AI systems end-to-end, contributing to technical direction and architecture
Build LLM-powered and agent-based solutions from concept through to production
Contribute to engineering standards, patterns, and reusable components across use cases
Make informed technical decisions on models, tooling, infrastructure, and system design within agreed architectural direction
Ensure systems are robust, observable, and production-ready (evaluation, monitoring, guardrails)
Provide technical guidance and mentorship to engineers contributing to AI initiatives
We're Looking For These Essential Skills
Proven experience delivering production-grade AI systems end-to-end
Experience designing and implementing complex AI systems across multiple use cases or domains
Strong expertise in generative AI / LLMs, including orchestration, prompting, and evaluation
Experience building agentic or multi-step AI systems
Strong software engineering fundamentals including APIs, system design, and cloud-based architectures
Ability to operate effectively in ambiguous or fast-moving problem spaces
Experience contributing to and influencing engineering standards and practices across projects
It's a plus if you also have these skills
Experience contributing to AI platforms or reusable frameworks and patterns
Familiarity with LLMOps / MLOps and production evaluation practices
Experience embedding AI into core business processes or enterprise systems
Experience working in large-scale or regulated enterprise environments
