They have expanded from $150M to $400M in revenue with double-digit international growth across 20+ countries, maintaining a high-impact, wellness-focused culture. They are building a shared AI Enablement Platform that allows every product team across the company to ship AI-powered features quickly, safely, and at scale.
Wymagania
- Significant hands-on engineering experience (10+ years) with strong backend/platform engineering expertise.
- Recent experience building and operating production backend/platform systems with deep involvement in code, APIs, infrastructure, observability, debugging, and tradeoffs.
- Proven experience building production-grade AI/LLM systems such as RAG, agent workflows, tool-calling systems, AI APIs, or LLM-powered product capabilities.
- Strong programming experience, preferably in Python and backend service stacks for production APIs and distributed systems.
- Deep understanding of API design, service boundaries, SDKs, integration patterns, reliability, testing, observability, performance, and cost optimization.
- Practical experience with LLM application architecture: context engineering, retrieval patterns, tool use, structured outputs, orchestration, fallback handling, and evaluation.
- Ability to build evaluation and validation systems for AI applications, including golden datasets, scenario tests, regression checks, and quality gates.
- Experience deploying and operating cloud-based production systems on AWS, GCP, Azure, or similar.
- Strong technical judgment to make tradeoffs between speed, reliability, safety, cost, developer experience, and business impact.
- Ability to lead through technical contribution: coding, reference implementations, design reviews, mentoring, and turning ambiguous needs into working systems.
- Proven ability to influence across teams via architecture reviews, design documents, technical standards, mentorship, and collaboration.
Nice to have:
- Experience building internal developer platforms, SDKs, shared services, or paved-path tooling.
- Hands-on experience with LLM observability/evaluation tools like Langfuse, LangSmith, or OpenTelemetry tracing.
- Familiarity with LangChain, LangGraph, LlamaIndex, Semantic Kernel, or custom orchestration frameworks.
- Experience with vector databases, embedding workflows, semantic search, retrieval tuning, and RAG productionization.
- Experience using AI-native engineering tools like Cursor, GitHub Copilot, Claude, ChatGPT, or similar.
- Experience writing technical blogs, internal guides, architecture documents, or enablement materials.
- Experience leading technical standards or architecture forums across multiple teams.
