Senior Full-Stack Architect – JavaScript & AI

What will you own? • Own the architecture of RockED’s full stack: Node.js backend services, React web apps, React Native mobile apps, data layer and cloud infrastructure. • Design scalable, resilient, maintainable systems with clear service boundaries, API contracts and data models. • Lead architecture and design reviews, and document key decisions and trade-offs so the whole team understands the “why.” Zero-to-one builds and system evolution • Build new systems and products from scratch, from first design to production rollout. • Lead major system redesigns and migrations, evolving the platform without disrupting users. • Pay down tech debt strategically, knowing when to refactor, when to rebuild and when to leave it alone. Hands-on engineering • Write production code across the stack every week. This isn’t a “slides and diagrams” architect role. • Build core business logic, APIs and data pipelines, and design relational database schemas for integrity, security and fast retrieval. • Own features end to end, from design to deployment and monitoring. Performance and user experience at scale • Make our apps fast, from API response times and database query optimisation to mobile app performance and front-end rendering. • Build with the end user in mind: smooth, reliable and responsive experiences on every device. • Set up observability (logging, monitoring and tracing) so problems are caught before users notice them. AI-native architecture • Define how AI fits into the platform, including LLM integrations, RAG pipelines, AI agents and intelligent features that make learning more personal. • Prototype quickly, measure honestly, and take AI from hackathon idea to production-grade feature. • Lead AI-assisted development in engineering: AI coding tools, automated testing and code review. Technical influence and standards • Build agreement on architecture decisions through clear thinking and strong communication, not authority. • Explain complex trade-offs simply to engineers, product managers and leadership alike. • Mentor engineers through code reviews, design discussions and pairing, and raise the technical bar across the team. • Work closely with Product and Design to turn ideas into well-built products and shape the technical roadmap. What do you bring? • 10–13 years of software engineering experience, with significant time at high-growth, product-based startups. • Proven experience building systems from zero to one and leading major architecture and design changes. • Prior work on B2C applications where performance and user experience mattered. Technical depth (must-have) • Extensive hands-on expertise in the JavaScript/TypeScript ecosystem: Node.js on the backend; React and React Native on the frontend. • Strong command of relational databases: schema design, query optimisation, indexing and data integrity. • Solid system design: distributed systems, microservices, event-driven architecture, API design (REST/GraphQL) and caching strategies. • Strong engineering fundamentals: CI/CD, automated testing (unit, integration, end-to-end), code quality and secure coding practices (OWASP). • Experience with Sequelize, MongoDB and AWS (e.g., EC2, Lambda, RDS, S3). • Experience with mobile-first products and app performance tuning. AI expertise (must-have) • Hands-on experience building with LLMs: prompt engineering, RAG, embeddings, vector databases and AI APIs. • A forward-looking view of where AI is heading, and how to architect for it. • Daily use of AI tools in your own engineering workflow. Who you are • Geeky and curious: you read engineering blogs for fun, try every new tool, and are always learning. • A builder at heart: you’d rather ship than talk about shipping. • An influencer, not a manager: you lead through expertise and earn trust through good decisions. • A clear communicator: you make complex ideas simple and trade-offs obvious. • Experimental and resilient: you try bold ideas, learn quickly from what doesn’t work, and see things through to completion. Why leaders choose RockED • Architect at the source: shape the technical foundation of a platform used across the US automotive industry. • An AI-first playground: leadership backing to experiment with and ship AI features, plus regular AI hackathons. [Add hackathon highlights and AI projects.] • A real seat at the table: work directly with RockED's founders and US leadership. Your voice shapes company strategy, not just engineering execution. • A proven business to scale: 10,000+ dealerships, 60,000+ learners and 11M+ lesson completions. You'll be scaling a business with established product-market fit. • Global leadership exposure: lead across US and India teams, and build your profile as a leader of global product engineering. • A team worth leading: engineers from IIT and ISB, and alumni of Adobe, Microsoft, Walmart and more, in a culture of high ownership and fast decision-making. • Room to grow with the company: as RockED scales, so does the scope of this role. • Care for you and your family: health and insurance coverage, fully sponsored by RockED.
