Job Requirements
Requirements are often considered a measure of how equipped you are to do the job, but sometimes, they aren't the only factor. If you don't have nearly enough experience, or not all the skills, we'd still like to hear from you. This could be the perfect fit for you and us.

• Strong command of a backend language (Java/Kotlin/Go/Python) and its runtime (GC, threading, memory).
• Solid CS fundamentals: data structures, algorithms, networking, and OS basics.

Concurrency & Distributed Systems

• Hands-on experience with concurrency, multithreading, and async patterns.
• Proven ability to profile and debug concurrency issues (race conditions, deadlocks, starvation).
• Solid understanding of distributed system concepts: consistency, resilience, and service-to-service communication.

Job Responsibilities
Vibe Engineering: AI-Assisted Development & Productivity
We believe that modern developers leverage state-of-the-art dev tools to maximize engineering efficiency.
The ideal candidate is experienced with AI-assisted development workflows , leveraging tools such as GitHub Copilot, Cursor, or similar LLM-based environments to rapidly prototype, debug, and evolve complex systems.
You should be comfortable translating ambiguous problem statements into iterative prompts, guiding AI agents to generate high-quality, maintainable code while applying strong engineering judgment. The role requires an ability to blend traditional software engineering practices with modern AI tooling-using automation, code generation, and conversational development to accelerate delivery without compromising architecture, reliability, or security.
What will you do?
As a Backend Engineer on the Platform/Infra team, you'll have a key role in designing, building, and maintaining the core services, infrastructure, and tools that enable all feature teams to build and scale their microservices reliably and efficiently. You should be passionate about operational excellence, performance optimization, and building robust, reusable components for internal engineers. You will be responsible for owning the dev cycle from technical design, through coding and defining robust SLOs/SLIs, to deployment and monitoring of critical shared services. We work in a true continuous delivery environment with fully automated QA processes on a microservices architecture, providing the foundation for deploying to production dozens of times every day.
