• Demonstrate total fluency in Ruby on Rails and at least one modern front-end environment, while maintaining the confidence and adaptability to work in any codebase on any platform by leveraging AI coding agents effectively. • Operate daily with Claude Code using structured, repeatable workflows: plan, decompose, implement, test, ship • Know when to trust AI output and when to verify it. You are the quality gate, not the rubber stamp • Review AI-generated code with discipline: know what patterns to trust, where to focus attention, and when to regenerate vs. fix manually • Use AI for planning before code exists: technical design, task decomposition, risk identification, and effort estimation • Serve as a technical resource for AI-augmented workflows across the engineering team, sharing playbooks, patterns, and tooling that help other developers level up • Build reusable agent skills, hooks, and guardrails that raise the team-wide baseline • Collaborate with product managers, front-end developers, and linguists across cross-functional teams • Participate in code reviews, sprint planning, and agile processes • Continuously research and evaluate new AI tools, models, and techniques with a framework for deciding what to adopt

• You will design, build, and iterate on AI-powered product experiences across Fleetio’s Rails and React application. • You will partner closely with Product, Design, Data, Customer Success, and other engineers to identify customer problems where AI can meaningfully improve the workflow. • You will create high-quality front-end experiences using Fleetio’s current React, TypeScript, Vite, Storybook, Tailwind, and component patterns, while caring deeply about accessibility, usability, maintainability, and performance. • You will work across the stack, including Rails APIs, database-backed product workflows, AI integration points, prompts, evaluation flows, observability, and customer-facing UI. • You will prototype quickly, learn from experiments, and help the team decide when to iterate, harden, or discard an approach. • You will review code and designs with a strong eye for user experience, front-end quality, correctness, readability, performance, security, and long-term maintainability. • You will mentor other engineers in React, TypeScript, Rails, AI tooling, experimentation, and pragmatic product engineering practices.

• Build and ship new features across Privacy.com’s product suite, working on both frontend and backend systems • Use AI coding tools (Claude Code, Cursor, Copilot, etc.) effectively across the full development lifecycle and help establish patterns for the team • Collaborate with product and design to translate requirements into technical solutions that prioritize customer experience • Think critically about user flows, edge cases, and how technical decisions impact the end-user experience, including where AI-generated code needs the most human scrutiny (security, payments correctness, edge cases) • Write clean, maintainable code with comprehensive tests and documentation • Participate in code reviews and pair programming to maintain quality, share knowledge, and raise the bar on how the team uses AI • Debug production issues and improve system reliability and performance • Contribute to engineering best practices and help scale our systems as the business grows
