About the role

Interested in a 🚀 start-up experience? We’re scaling fast at Zip (YC S2020) and hiring our next 20 engineers!

Zip is tackling the $50B+ TAM space to transform the way businesses manage spend. We started Zip because we saw the challenges companies had using outdated 20 year old software to manage hundreds of millions of dollars every year. We are a small but mighty team that helped scale category-defining companies like Airbnb, Facebook, Salesforce, Apple, Quora, Pinterest, and Square.

Your Role

We’re growing quickly and need your help: we launched in early 2020 and are growing by 40+% every month. We have a wide product surface area, covering request management, no code workflow builders, customer-facing reporting dashboards, connections to ticketing systems, integrations with financial systems, B2B payment processing and more.

As a software engineer you will be responsible for building Zip’s core products and architecture. You will ship features that will be immediately used by our users, and will work with a tight-knit team that values open communication and cross-functional collaboration. We move quickly to solve a wide range of complex technical and product challenges. While we are an experienced team that can provide constant guidance and mentorship, we value engineers who can autonomously scope and solve difficult technical challenges.

Your Role

Take full ownership of Zip's backend infrastructure, optimizing for scalability, availability, reliability, maintainability and performance.

You Will

  • Proactively improve systems and run capacity planning to make sure the infrastructure is scaled to meet the product growth.
  • Implement a holistic view of system health with thorough monitoring across systems and products.
  • Improve system reliability and implement solid failure-over and disaster recovery strategies.
  • Proactively find and implement opportunities to improve site performance.
  • Maintain DevOps systems and ensure development uptime


  • 5+ years of software engineering experience in backend infrastructures.
  • BS or higher, in Computer Science or related technical field involving coding (e.g. physics or math)
  • Experience working with Kubernetes, AWS, nginx and service mesh framework such as istio.
  • Experience working with ElasticSearch, Redis, Kafka, Celery is a bonus, but not required.
  • Experience working with DevOps systems such as Jenkins, Spinnaker is a bonus, but not required.
  • Experience working at a small company with diverse responsibilities is a bonus, but not required.
  • Ability and interest to quickly learn new frameworks, architecture patterns, and programming languages as needed

Why you should join Zip

Who we are:

From utilizing new SaaS tools to hiring expert consultants, modern companies rely on external vendors more than ever before. Yet companies still rely on legacy ERP systems, some built over a decade ago, to manage spend and compliance. That’s why we started Evergreen (YC S2020), the first modern spend management system. We provide one place for employees to request any purchase and manage approvals across finance, legal, security, procurement, and IT.

We are a small but mighty team that have helped scale category-defining companies like Airbnb, Facebook, Apple, and Salesforce. We’re building a world-class engineering team to create the next generation of enterprise spend management products.
