Staff AI Architect

At Robots & Pencils, we design AI systems for a human world. Our name says it all. Robots and pencils means engineering paired with creativity, because every agent we ship has to work for real people in real workflows. That balance is baked into how we operate.

Every role here contributes directly to that mission. Here, you shape how AI systems integrate into enterprise operations, how teams move at real velocity, and how products create measurable impact for clients and the people they serve. We ship production-ready AI in 30 to 45 days. That pace demands people who take ownership, lead with craft, and care deeply about what they put their name on.

What You’ll Do

Craft & Delivery

Define AI system architecture and lead design across LLM applications, agentic systems, retrieval, and ML model serving for end-to-end engagements

Drive RAG and context-engineering strategy, including hybrid retrieval, reranking, chunking, and embedding model selection across vector stores

Lead multi-agent orchestration design using frameworks such as LangGraph, Amazon Bedrock Agents, or AgentCore

Own model serving and inference architecture on AWS, optimizing latency, throughput, and cost with streaming, caching, batching, and quantization

Define LLMOps and MLOps standards across engagements, including prompt versioning, eval pipelines, CI/CD, and feature stores

Drive evaluation, guardrails, and observability strategy, establishing offline and online eval, LLM-as-judge scoring, and tracing

Own the responsible AI posture for AI systems, including governance, PII and data isolation, prompt-injection defense, and grounding controls that reduce hallucination

Lead decisions on build approach, including fine-tuning, prompting, RAG, and tool use, weighing accuracy, cost, and maintainability

Bring an AI-forward mindset to your daily work, using tools like Claude, Cursor, and other modern AI assistants to ship higher-quality work at pace

Collaboration & Communication

Partner with leadership and clients on AI technical direction, translating business goals into architectural decisions

Communicate complex AI concepts and tradeoffs clearly to engineering and non-engineering stakeholders alike

Engage closely with engineering, data, ML, and product teams to align AI architecture with broader business priorities

Develop and maintain AI architecture documentation, evaluation standards, and reusable patterns

Leadership & Influence

Establish architectural standards and best practices that lift quality and consistency across the team

Mentor junior and mid-level engineers, helping them grow their architectural thinking and craft

Act as a technical escalation point on complex architectural and integration challenges

Evaluate emerging technologies and recommend tools, frameworks, and patterns that improve architecture over time

What You’ll Bring

7+ years of professional software engineering experience, with at least 3 years in AI/ML architecture or technical leadership roles

Deep expertise in LLM and agentic application architecture, including multi-agent orchestration and tool-calling patterns

Strong experience designing production RAG and retrieval systems, including hybrid retrieval, reranking, and vector store selection

Strong experience with model serving and inference optimization on AWS, including latency, throughput, and cost tuning

Deep understanding of LLMOps and MLOps, including eval pipelines, prompt versioning, CI/CD, and observability for AI workloads

Demonstrated experience with AI evaluation, guardrails, and tracing tooling

Strong judgment on fine-tuning versus prompting versus RAG tradeoffs for accuracy, cost, and maintainability

Expert software engineering background, with proficiency in Python and at least one other language (e.g., TypeScript, Java, Go)

Strong background in cloud-native architecture, including microservices, serverless, containerization, and event-driven systems

Strong understanding of responsible AI and governance, including data isolation, prompt-injection defense, and compliance

Demonstrated leadership and technical mentoring experience across a team

Demonstrable, day-to-day usage and expert knowledge of AI-forward tools such as Claude and Cursor

Excellent problem-solving skills and the ability to navigate highly ambiguous technical and business challenges with sound judgment

AWS AI certifications, fine-tuning or model customization experience, or responsible AI experience is a plus

Helpful Extras and Unique Skills

You’ll Do Well Here if You Are

A doer. You see something broken and fix it. You'd rather move on clarity than wait for certainty.

A fast learner who knows you don't know everything. The AI landscape changes weekly. You're senior enough to know better and curious enough to keep learning anyway.

Direct in a way that makes the work better. You give honest feedback. You'd rather have the hard conversation than blow smoke.

Obsessed with craft. You know genius is in the details. You ship exceptional, not perfect, and you don't put your name on work you wouldn't stand behind.

Built for ownership. You honor commitments, admit mistakes fast, and back your teammates when a decision costs something. No handoffs, no finger-pointing.

All in. You treat clients' businesses like your own. You take the work seriously without taking yourself seriously.

Resourceful when the budget, timeline, or team is tight. Constraints don't slow you down. They sharpen you.

Glad to be in the room with people who care as much as you do. Our teams average fifteen-plus years of experience. We hire people who push each other to do better work.
