About The Position

The client is a leading mobile and web-based learning platform that delivers efficient and affordable study solutions for professional certifications. Guided by the belief that education should be accessible to everyone, the platform aims to remove the stress and financial barriers often associated with professional certification exams by preparing members to pass with confidence and advance their careers. The engineering team collaborates closely with the product and design teams to build and maintain the technical foundation of the platformâs applications. As stewards of the codebase, engineers are dedicated to their craft, delivering high-quality, resilient, and accessible products that support learners from all backgrounds in achieving their goals. The team continuously refines its processes, coding standards, and architectural patternsâboth individually and collectivelyâto ensure readiness for future challenges. Role Overview The Staff Full-Stack Engineer on the Platform team plays a key role in research, experimentation, and early product development. This role focuses on exploring, validating, and prototyping new technologies and product concepts, often through the development of early-stage minimum viable products (MVPs) that help the broader organization evaluate new capabilities and opportunities. In addition to R&D initiatives, the role contributes to core platform systems, ensuring that backend services and APIs align with the companyâs long-term architectural direction. This engineer operates with a high degree of autonomy, working from loosely defined goals and translating them into practical, scalable technical solutions. As a senior technical contributor, the Staff Full-Stack Engineer collaborates closely with engineering, product, and design partners to rapidly iterate on concepts, connect experimental systems to existing platforms, and assess tradeoffs between speed, quality, and maintainability. The role spans the full stack, including backend services, frontend integration, and interaction with AI/ML systems.

Requirements

8+ years of professional engineering experience, with significant ownership across backend and full-stack systems
Deep expertise in TypeScript, including designing and maintaining large, production-grade codebases
Strong experience building and maintaining APIs and backend services (security, rate limiting, reliability, observability)
Demonstrated ability to work independently on ill-defined problem statements
Experience integrating or experimenting with AI/ML systems in practical, product-oriented ways
Strong commitment to code quality, testing, and clear technical documentation

Nice To Haves

Experience building production systems in additional languages (e.g., Python)
Experience working with large language models (LLMs), embeddings, or AI-driven workflows
Experience with MongoDB or other NoSQL databases, including performance optimization
Experience taking projects from early concept through prototype, evaluation, and iteration
Prior experience mentoring engineers or acting as a staff-level technical leader

Responsibilities

Design, build, and maintain backend services using TypeScript and Node.js, with a strong focus on reliability, performance, and scalability
Lead and execute experimental initiatives, translating ambiguous product or research goals into working prototypes and MVPs
Collaborate cross-functionally to design APIs and infrastructure that support both experimental features and long-term platform needs
Work across frontend and backend systems to ensure smooth integration and usable end-to-end experiences
Evaluate, integrate, and experiment with AI/ML systems, balancing innovation with practical engineering constraints
Identify system bottlenecks and architectural risks, and independently drive solutions
Monitor production systems, debug complex issues, and optimize database and service performance (MongoDB)
Provide technical leadership through mentorship, code reviews, and contributions to architectural discussions and engineering standards
