ABOUT THE ROLE

Hiring a senior backend engineer to join our team and focus on system architecture our most popular products.

THINGS YOU'LL BE WORKING ON

Architecting and implementing backend systems in Typescript/Node is the core of what you’ll be doing. Real examples include —

- Designing and building an ingestion pipeline for our analytics/insights products (> 99.99% uptime on Kafka, Clickhouse, Redis)

- Spiking on our CI/CD to improve stability

- Build out durable/distributed cart/hosting for our ecommerce product

- Deploying a multi-tenant NextJS app for shops in Cloudflare

- Mentoring junior engineers on best-practices

LOOKING FOR SOMEONE WHO

- Can be in office 3-4 days/week in San Francisco

- Has deep knowledge in distributed systems and SOA — load balancers, databases, queuing, caching, HTTP, APIs, high-availability, fault tolerance, redundancy, at-least-two-of-everything

- Down to do full-stack work (including frontend even if it's not your main role)

- Is ALWAYS SHIPPING. We don't spend weeks planning features at Replo

- Has 4+ years of professional experience with production distributed systems, service oriented architecture

- Proficient in Typescript. If you have experience writing these systems in Python/Go/Java that’s cool too, as long as you’re willing to learn Typescript/Node — the learning curve on writing TS isn’t that high for high-caliber engineers. Experience or working knowledge of React is great too, but we can teach you that if we need to

- Has a product and customer-focused mindset

- Has experience being burned by deployment and maintenance issues. If you have a a strong opinion on how backend systems should be built, that’s good

- Values writing clean, maintainable software, including documentation (e.g. the code needs to be correct and run fast, but we’re the ones that have to read it and understand it)

- Is comfortable with ambiguity and defining software architecture patterns to solve customer pain...
