Full Stack Developer (TypeScript/React/NestJS) (m/w/d), Vienna

About us

Our mission is clear: we help people achieve their dream jobs. With intuitive software that inspires and the use of cutting-edge technologies like AI and LLMs, we are developing a novel career platform. Sprad is a fast-growing startup with customers worldwide. Our experienced, dedicated team aims to sustainably revolutionize the way people discover fulfilling activities.

We're looking for a Full Stack Developer to join our small, focused team in Vienna. You'll have real ownership over features from specification to deployment, working primarily in our modern TypeScript stack (Next.js, NestJS, LangGraphJS) while helping us migrate away from legacy PHP/Symfony code.

This isn't just a maintenance role. You'll be building new features, shaping our architecture, and directly impacting how we develop software. We value pragmatism over perfection, clean code over clever tricks, and shipping over endless planning.

• Build end-to-end features in our TypeScript monorepo (Next.js frontend + NestJS backend + LangGraphJS agents)
• Migrate legacy PHP/Symfony code to modern TypeScript, refactoring, not rewriting from scratch
• Maintain and debug existing systems across the stack
• Write tests (Vitest, Playwright) and participate in code reviews to maintain quality
• Collaborate through pair programming and contribute ideas to improve our processes, tooling, and engineering practices
• Own your work, from database design to API contracts to UI implementation

Frontend

• Experienced with React, React Router, Next.js, Vue/Nuxt, or similar Frameworks
• Solid TypeScript knowledge
• Familiarity with Tailwind CSS

Backend

• Strong Node.js + TypeScript experience
• Experienced in NestJS, Express, Fastify, or similar Frameworks
• Experience with RESTful API design
• Understanding of database design & ORMs (MySQL/PostgreSQL)

Bonus points for experience with:

• Willingness to refactor PHP into TypeScript (we'll support you)
• Docker & Docker Compose for local development
• Git & GitHub workflows, CI/CD (GitHub Actions)
• Understanding of monorepo architecture (Turborepo/pnpm)
• LangGraphJS / AI agent development (LangChain ecosystem)
• AWS (SQS, RDS, S3, ECS)
• Testing mindset (Vitest, Playwright, etc.)
• Multi-tenant systems

This describes you:

• Quality-focused but pragmatic
• Independent, thoughtful, and long-term oriented
• Communicative (excellent English or German OR strong knowledge of both)
• Enthusiastic about learning and tackling new challenges
• Strong in logic and problem-solving

• Real Ownership: Your ideas and contributions directly shape the product
• Small Team: Direct impact, no bureaucracy, fast decisions
• Modern Stack: Work with cutting-edge tools (Next.js 15, LangGraphJS, AI agents)
• VSOP Option: Share in the company’s success through virtual stock options
• Modern Equipment: Top-tier gear, including a MacBook Pro
• Central Office: City-center location with air conditioning and great infrastructure
• Quality Coffee & Team Events: Portafilter coffee machine, regular team dinners, and events
• Hybrid Work Model: Flexible mix of remote and in-office work

We’re looking for a talented developer who enjoys building products and taking ownership. You’re a team player who values collaboration over spotlight, and you want to help shape something meaningful.

If that sounds like you, we’d love to hear from you!
