Staff AI Engineer

Staff AI Engineer

Onsite 1-2 Day(s) a Week in Newark, NJ Office.

At Robots & Pencils, we build meaningful, scalable digital products that solve real business problems.

We’re looking for a Staff AI Engineer to support the development and delivery of complex, integration-heavy platforms. This role is ideal for an experienced engineer who thrives in hands-on development, can confidently own features and deployments, and contributes to team leadership within a pod.

In this role, you will work as a key contributor on a cross-functional team, building across the stack while helping guide delivery, improve systems, and solve challenging integration problems, including AI-native platforms such as agentic learning systems designed to enable human-centered learning in the Age of AI.

This is not a greenfield project. You’ll be joining a mature, production environment with real users, where reliability, performance, and scalability are critical. You’ll collaborate closely with senior engineers to enhance existing systems and deliver high-quality features.

By joining us, you leverage our Advanced AWS Partnership and the highly exclusive AWS Patterns Partnership, a distinction held by only 11 companies worldwide out of 190,000.

What You’ll Do

Development

• Build and maintain backend services using Python and Node.js, including serverless architectures (e.g., AWS Lambda, API Gateway)
  • Develop and integrate APIs that support frontend applications and external systems
  • Contribute to frontend features and ensure smooth integration across the stack
  • Write clean, maintainable, and well-tested code with strong unit testing practices

Workflow & System Orchestration

• Support the development and maintenance of workflows using orchestration tools (e.g., Sequencer / workflow engines, state machines)
  • Contribute to event-driven processes and asynchronous system operations (e.g., SQS,EventBridge)
  • Assist in improving reliability through better error handling and retries

Backend & API Engineering

• Develop RESTful APIs and support the BE architecture
  • Integrate with third-party services and internal systems, including AI-driven platforms
  • Assist in optimizing performance and scalability of services using DynamoDB single-table design patterns (composite keys, transactional writes)
  • Implement secure and reliable data handling practices

System Reliability & Support

• Troubleshoot issues in production environments with guidance from senior team members
  • Contribute to logging, monitoring, and debugging efforts
  • Support deployment and release processes in cloud-native environments (AWS, Docker)

Collaboration & Growth

• Work closely with cross-functional teams across global locations
  • Participate in code reviews and team discussions
  • Take ownership of assigned features and tasks, delivering end-to-end solutions
  • Continue developing technical skills and leveraging AI-assisted development tools (e.g., Claude Code)

Required Skills & Experience

• 6+years of professional software engineering
  • Strong experience with Python and Node.js
  • Experience with LLM function/tool calling, prompt engineering, multi-agent orchestration, vector databases (OpenSearch), embeddings, streaming LLM responses, RAG concepts.
• Experience working with AWS cloud environments, including Lambda, DynamoDB (and Single-Table design), S3, SQS, EventBridge, Step Functions, etc.
• Experience building and maintaining fullstack applications
  • Exposure to workflow orchestration tools (e.g., Sequencer or similar systems)
  • Solid understanding of API design and backend systems
  • Familiarity with databases (SQL and/or NoSQL, including scalable design patterns)
  • Experience working in production environments
  • Strong unit testing practices and maintainable test strategies
  • Experience with containerization (e.g., Docker)
