Full-Stack Application Architect

2 weeks ago


Budapest, Budapest, Hungary Aliz Full time 120,000 - 240,000 per year

Rabbit is a GCP cost-optimization and automation platform that helps enterprises make BigQuery and other GCP workloads truly cost-efficient. We combine deep platform intelligence, automation, and generative AI to turn cost insights into action.

The Challenge: Cloud costs are spiraling out of control for enterprises, and traditional monitoring tools just show the problem — they don't fix it. We're building the first truly intelligent cost optimization platform that doesn't just recommend, but automates.

Role Overview

This is not your typical architect role. We're looking for a Full-Stack Application Architect who wants to build something from the ground up — someone who gets energized by ownership, thrives on technical challenges, and wants their work to matter.

You'll own Rabbit's application architecture end-to-end — from backend microservices to user-facing integration. This is a hands-on role: you'll design, build, and ship. You'll work closely with data and optimization architects to turn BigQuery insights and automation logic into reliable, scalable, user-facing features that enterprise customers depend on.

The opportunity: In our startup environment, you're not executing someone else's vision — you're creating it. Your architectural decisions will shape how the product evolves. Your ideas won't get lost in bureaucracy; they'll ship to production within days. If you're ambitious, opinionated, and ready to build something extraordinary, this is your stage.

What You'll Do
  • Own Rabbit's system and application architecture, including service boundaries, APIs, and data flows
  • Design and implement modular backend services (Java and ) and frontend integrations (React, TypeScript, Material-UI)
  • Lead development of Rabbit's automation framework — APIs for query optimizers, job-level cost controllers, and recommendation execution
  • Define and enforce internal API contracts, versioning, and interface standards between data, backend, and UI layers
  • Interact directly with Postgres and BigQuery using SQL for data modeling, performance analysis, and feature development
  • Mentor backend and frontend engineers on scalable architecture patterns and clean code practices
  • Work with the CPO and Product team to validate designs through working prototypes, not just diagrams
  • Drive architectural decisions around scalability, security and development velocity
  • Design and maintain the end-to-end development lifecycle, including CI/CD pipelines, deployment strategies, infrastructure as code, and observability practices
  • Investigate and resolve real-life customer issues, working directly with enterprise clients to understand their challenges and deliver solutions
What We're Looking For
  • 8+ years in software engineering, 3+ years in system or application architecture
  • 3+ years of hands-on GCP experience
  • Strong backend experience in Java and
  • Comfortable with frontend development (React, TypeScript, Material-UI)
  • Confident writing and optimizing SQL queries in Postgres and BigQuery
  • Deep understanding of API design, asynchronous processing, and event-driven systems
  • Strong DevOps skills including CI/CD (GitHub Actions, Cloud Build), infrastructure as code (Terraform), containerization (Docker), and monitoring/observability
  • Cloud-native mindset with proven ability to design and scale production systems on GCP
  • Strong sense of ownership, eager to experiment, and pragmatic about trade-offs
  • Bonus: exposure to BigQuery optimization, cost analytics, or AI/LLM integrations
Why Join Rabbit

For ambitious builders who want impact, not politics:

  • Own the architecture, own the impact: This isn't a role where you write proposals that disappear into committees. You design it, you build it, you ship it — and you see it transform how Fortune 500 companies manage billions in cloud spend
  • Ship fast, learn faster: Your ideas go from concept to production in days, not quarters. We value speed, iteration, and results over perfect documentation
  • Work with the best: Collaborate with senior architects and domain experts who are as ambitious and technically curious as you are — no hand-holding, no micromanagement, just smart people solving hard problems together
  • Build the future of AI-driven automation: Help pioneer how generative AI transforms infrastructure automation — this is uncharted territory, and you'll help define it
  • Grow exponentially: You'll learn more in 6 months here than in 2 years at a typical enterprise. Startups compress years of growth into months for those who can keep up

Not for everyone. Perfect for you if: You'd rather be challenged and respected than comfortable and bored. You measure success by impact, not title. You want to build something that matters.
