PositionKueski is seeking a Staff AI Software Engineer to join the AI Enabling Team.
This role is ideal for a hands-on engineer who will build harnesses, developer tools, reusable workflows, and guardrails that enable Engineering and Product teams to use AI agents effectively at scale.
Job RequirementsExperience building and shipping AI products, combined with a strong perspective on transforming legacy organizations into AI-native ones.
10+ years building software, with several spent designing and shipping ML/AI systems in production at scale.
Strong systems and software engineering fundamentals.
A track record of Staff+ technical influence, setting direction that multiple teams follow, and being trusted to make high-ambiguity calls with incomplete information.
Sharp judgment on the build/buy/fine-tune/prompt spectrum, and the discipline to optimize for outcomes and cost.
Clear communicator who can align engineers, PMs, and risk/compliance stakeholders — and give a direct technical opinion when it matters.
AI-Native Foundations
We're not starting from a blank page, you'll evolve Kueski's existing services, data platforms, and pipelines into systems that AI agents and models can operate on safely and effectively. Decide what to wrap, refactor, expose, or retire to make our infrastructure legible and actionable to AI, and sequence that transformation without a rewrite-the-world reset.
Make Kueski's knowledge (code, data, business logic, docs, and operational state) structured and retrievable so LLMs and agents can reason reliably over our real systems. Own the retrieval, memory, and knowledge-representation layer that turns scattered institutional context into something models can actually use.
AI-Native Engineering Workflows
Redefine how we build (specs, code, review, testing, deployment) around agentic engineering workflows. Set the standards, tooling, and guardrails that make AI a default part of the development lifecycle rather than a side experiment.
Production Systems, Evaluation & Guardrails
Design and ship the agentic systems behind our internal workflows, and take at least one high-stakes AI capability all the way to production, proving the impact with data.
Establish the eval harnesses, observability, and safety/compliance guardrails that make AI trustworthy in a regulated lending environment: PII handling, model risk, and auditability.
Organizational Leverage
Build reusable platforms and reference implementations, raise the engineering org's AI-native fluency through direct collaboration and mentorship, and turn one-off wins into self-sustaining capability.
At Kueski we embrace diversity in all forms, systematically promote equity, and ensure everyone feels included with a sense of belonging. We are committed to the full inclusion of all qualified candidates. As part of this commitment, we will make efforts to ensure reasonable accommodations are made during the hiring process. If reasonable accommodation is needed, please let the Talent Acquisition team know.
