If thats bubbly, shy, precise, funny, bold, kind, honest, brilliant, or anything in between, were waiting with open arms. Come join us.
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, youll 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.

Requirements:
Requirements are often considered a measure of how equipped you are to do the job, but sometimes, they arent the only factor. If you dont have nearly enough experience, or not all the skills, wed still like to hear from you. This could be the perfect fit for you and us.
Core Technical Expertise:
6 years of experience as a software engineer with a strong emphasis on backend development.
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.
API & Abstraction Design
Ability to design clean, stable, and ergonomic APIs.
Experience building reusable, versioned, and backward-compatible internal libraries/frameworks.
Platform Engineering & Reusability
Experience building internal libraries, frameworks, or SDKs consumed by multiple teams.
Strong ability to design scalable abstractions that balance flexibility and simplicity.
Database & Storage:
Strong practical experience with relational databases (PostgreSQL/MySQL), indexing, and query optimization.
Familiarity with distributed storage/message systems (Redis, Kafka, Elastic/OpenSearch).
Understanding of consistency models, failure modes, and data distribution strategies.
Scale & Performance
Experience designing and operating systems at scale (high throughput, low latency, multi-tenant).
Skilled in performance optimization, profiling, and bottleneck identification.
Knowledge of scaling strategies (sharding, partitioning, caching tiers).
