Staff AI Engineer (AI Enablement Platform)

About the role

ABC Fitness is building a shared AI Enablement Platform that allows every product team to ship AI-powered features quickly, safely, and at scale. The goal is simple: remove the plumbing so product teams can focus on customer value instead of reinventing AI infrastructure. This platform provides the paved path for building production AI systems across ABC, including: Reusable APIs for chat, summarization, RAG, classification, and AI workflow execution Agent orchestration patterns for multi-step reasoning, tool use, validation, and fallback handling Evaluation and validation systems to measure output quality and prevent regressions Observability, policy enforcement, cost controls, and production guardrails Developer experience, documentation, templates, and reference implementations that help teams adopt AI faster At ABC, we love entrepreneurs because we are entrepreneurs. We roll our sleeves up, we act fast, and we learn together. As a Staff AI Engineer - AI Enablement Platform , you will be one of the core technical builders of ABC's AI platform. This is a deeply hands-on individual contributor role . You will be expected to write production code, design and build reusable platform services, review technical designs, debug production issues, and partner directly with product teams to drive adoption. You will also influence technical direction, establish engineering patterns, and help teams adopt the platform, but your credibility will come from building real systems , not just advising from the sidelines. This role is not focused on ML research, data science, or training models from scratch . We are looking for a strong platform/backend engineer with deep hands-on experience building production-grade LLM systems , APIs, orchestration layers, evaluation systems, and developer-facing tools. You will help turn AI from isolated experiments into a repeatable engineering capability across ABC.

Responsibilities

• Build the AI platform foundations
• Write and ship production code for core AI platform services, APIs, orchestration components, evaluation systems, SDKs, and internal developer tools.
• Design, build, and operate reusable AI platform capabilities such as chat APIs, RAG services, summarization, classification, semantic search, prompt/workflow execution, and agent orchestration.
• Build high-quality APIs, SDKs, templates, and reference implementations that product teams can adopt with minimal friction.
• Create production-ready orchestration patterns for retrieval, tool use, validation, fallback handling, memory/state management, and human-in-the-loop workflows.
• Stay close to implementation details by reviewing PRs, debugging production issues, improving reliability, and making pragmatic technical tradeoffs with the team.
• Partner with SRE, Security, Platform, and Product Engineering teams to ensure the platform is reliable, scalable, secure, observable, and cost-aware .
• Own evaluation, reliability, and production readiness
• Build evaluation harnesses for LLM-powered systems, including curated test sets, scenario-based evaluations, regression checks, quality gates, and release criteria.
• Implement AI observability practices such as tracing, prompt/version tracking, output quality monitoring, latency tracking, token/cost visibility, and production feedback loops.
• Design safe defaults for AI systems, including structured outputs, tool permissions, prompt-injection awareness, data handling controls, fallback paths, and failure-mode handling.
• Ensure AI capabilities are built with strong production fundamentals: testing, monitoring, rollout strategy, incident readiness, performance tuning, and cost management.
• Help teams move from prototypes to production by identifying gaps in reliability, observability, security, evaluation, and operational readiness.
• Drive AI adoption across ABC
• Establish the "ABC Way" of building production AI systems through patterns, standards
