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.
