Job summary

Strider is building an Education Technology platform with user-facing web apps for families, school staff, and internal ops. You will advance front-end quality, design scalable components, and ship features end-to-end across the stack using TanStack Start, Mantine, and TypeScript.

Join a startup environment that embraces AI-assisted tooling, rapid iteration, and strong collaboration with product, design, and AI teams, while maintaining high code quality and security practices.

Qualifications

• 5+ years of full-stack experience with strong front-end and solid Python back-end skills.
• Expert-level TypeScript and React.
• Strong HTML and CSS experience.
• Significant Python experience, ideally FastAPI, Pydantic, and async SQLAlchemy.
• Experience with server-side rendering in a full-stack React framework (TanStack Start, Next.js).
• Front-end architecture experience: reusable component libraries, forms and validation, data fetching and caching, and front-end performance.
• Experience designing RESTful APIs with OpenAPI and typed API clients.
• PostgreSQL skills: schema design, migrations, indexes, constraints, transactions.
• Strict static typing in TS and Python.
• Automated tests experience (pytest, Vitest, Testing Library).
• Docker & Docker Compose for local development.
• Git + PR reviews + CI pipelines (GitHub Actions).
• Experience with AI-assisted engineering tools and reviewing/refining AI-generated code.
• Strong collaboration with team, product, design, AI teams; startup move-fast mentality.
• Strong English communication (spoken & written).

Responsibilities

• Build and evolve an Education Technology platform with web apps for families, school staff, and internal operations.
• Raise the bar for front-end quality: component design, accessibility, performance, UX polish.
• Ship features end-to-end: PostgreSQL schema/migrations, Python (FastAPI) services, React screens with TanStack Start, Mantine, and TS.
• Work in a modular monorepo (Python/TypeScript); read/write Architecture Decision Records before significant changes.
• Build secure, multi-tenant features: sign-in via OpenID Connect (Keycloak), fine-grained permissions, student/family data handling.
• Investigate and fix bugs, performance bottlenecks, and related issues.
• Maintain code quality through peer reviews, automated testing, CI gates, and best practices.
• Produce clean, efficient, well-documented code.
• Collaborate with product management, design, and engineering to ship reliable solutions.
• Keep current with emerging technologies and industry trends.
