[Hiring] Senior AI Developer @ClickUp

Role Description

We're looking for a highly skilled and experienced Senior AI Engineer to join our ClickUp Engineering team, with a focus on AI evaluations. You'll own how we measure and improve the quality of ClickUp's AI:

• Building the eval systems that tell us how well our AI is performing.
• Developing the core agent harness and the AI that performs well on those evals.
• Working on backend systems that make AI-powered capabilities scalable, reliable, and secure.
• Hands-on work with LLMs to solve real user problems and drive product innovation.

Key Responsibilities:

• Design, build, and own ClickUp's AI evaluation system, including golden datasets, LLM-as-judge and automated scorers, regression detection, and quality tracking across AI features.
• Build and evolve the core agent harness, partnering closely with product and engineering to define what "great" looks like.
• Build self-improvement loops where agents modify other agents or prompts, rerun evals, and iterate automatically.
• Benchmark new models as they're released and own model selection, routing, and fallback strategies across providers (e.g., OpenAI, Anthropic, Google, open-weight), balancing quality, latency, and cost.
• Architect, design, and implement scalable AI platform services that support the deployment, orchestration, and lifecycle management of LLMs and other AI models.
• Build and maintain robust APIs and backend systems that integrate AI-powered features into ClickUp's core platform.
• Develop infrastructure for model serving, monitoring, logging, and automated evaluation to ensure high reliability and performance of AI services in production.
• Drive best practices in AI privacy, security, and compliance, including data anonymization, secure data handling, and regulatory adherence.
• Collaborate cross-functionally with product, frontend, and data teams to deliver seamless, reliable, and user-centric AI experiences.

Qualifications

• 5+ years of software engineering experience, including 2+ years building production LLM or ML systems.
• Hands-on experience building LLM evaluation systems in production (golden datasets, LLM-as-judge, judge calibration, offline and online evals), tied to real product quality.
• Strong experiment design and statistical rigor, including A/B testing, offline vs. online metrics, and separating real regressions from noisy or variable results.
• Proven track record of applying LLMs and AI models to real-world, customer-facing product features.
• Proven experience integrating and managing multiple LLMs, including benchmarking, routing, and cost/latency/quality tradeoffs.
• Deep expertise in backend engineering, distributed systems, and cloud-native technologies (e.g., Kubernetes, Docker, AWS/GCP/Azure).
• Strong programming skills in Python (preferred), Go, TypeScript, or similar languages used for backend and AI platform development.
• Proficiency in orchestration frameworks and workflow engines (e.g., LangGraph, Airflow, Ray, or similar).
• Familiarity with search and retrieval technologies and their integration into AI-driven applications.
• Excellent collaboration and communication skills, with a track record of working effectively in cross-functional teams.
• Passion for staying at the forefront of AI and applying new technologies to solve real-world problems at scale.

Requirements

• Background in data science, applied science, or machine learning engineering (Nice to Have).
• Experience with eval tooling (e.g., Braintrust, LangSmith, Weave, Arize, or in-house frameworks) (Nice to Have).
• Experience with model routing, AI gateways, or inference optimization (Nice to Have).
