Company Overview

Robots & Pencils is an applied AI engineering firm building the next frontier of business architecture. We design and ship AI co-workers that integrate into enterprise operations and deliver measurable results for our clients. We're all in on AWS, combining deep UX capability with senior engineering talent to get AI into production fast and keep it there.
We’ve earned the trust of leaders across Consumer Products and Retail, Education, Energy, Financial Services, Healthcare, and Manufacturing and more, and earned a reputation as the nimble alternative to traditional global systems integrators. Founded in 2009, with delivery centers in Canada, the United States, Eastern Europe, and Latin America, we are smaller, faster, and more senior by design. Our teams average 15+ years of experience. We move fast, sweat the details, and build things that actually ship.

Position Overview

We’re looking for a Senior Full-stack Engineer (L4) to contribute to the development and delivery of complex, integration-heavy platforms.  Our client is a US resort in the first phase of a large scale digital transformation initiative, beginning with Mobile Apps integrated with their in-house systems. 

The ideal candidate is comfortable working within a modern enterprise digital ecosystem supporting native iOS and Android mobile applications, API-driven architectures, middleware platforms such as MuleSoft, authentication and identity management solutions like AWS Cognito and OAuth, and cloud-based infrastructure within AWS environments. Experience working with content management systems and personalization platforms such as Contentful and Uniform is highly valuable given the project’s dynamic content and guest personalization requirements.  

What You’ll Do

• Develop scalable back-end services : Optimize backend performance, scalability, and reliability, and implement security best practices including authentication and authorization
• Contribute to event-driven architectures and asynchronous system operations
• Collaborate with MuleSoft, Contentful/Uniform, and Mobile App teams to deliver high-quality product features 
• Work closely with architects and product owners on system design and implementation 
• Participate in code reviews and contribute to a culture of excellence 
• 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
• Contribute to shared engineering practices that lift the quality of work across the team

What You’ll Bring

• 7+ years of professional software engineering experience, focused on back-end development (e.g., Node.js, Python) and API integration
• Strong hands-on experience with AWS Lambdas, Node.js and GraphQL
• Experience with event driven processing
• Demonstrable usage of AI-forward tools such as Claude Code or Codex in software development lifecycle  
• Solid knowledge of SQL and NoSQL dbs
• Experience working in agile teams and delivering production-ready software 
• Experience with CI/CD pipelines (e.g., GitHub Actions, GitLab CI)
• Upper-Intermediate level of English (written and spoken) 

Helpful Extras and Unique Skills

• Experience with Contentful and Uniform 

 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.
