Swift is building a next generation checkout stack for India - a platform rolling up payments and logistics solution for all fulfillment needs. We give businesses the opportunity to provide a customer experience at par with the likes of Amazon and Flipkart, all the while saving money and time.
Its basically Amazon without the website listing - we let our sellers design their own sales channel :-)
We believe there are many things a seller or small business has to worry about when selling online, logistics/payments/etc shouldn't be one of them. With our solution, SMBs and D2C brands get access to technologies and services like next day delivery, same day delivery, live package tracking, Card/Cash on delivery, scheduled delivery etc, making parcel delivery just as simple as collecting payment.
We also provide robust APIs which makes it easy for developers to add shipping capabilities to their multichannel online store.
We want to be the #1 checkout platform that’s reliable, easy to use and affordable.
About you:
You have experience in Java/Scala/JVM based languages and have an understanding of server design and implementation. You are looking for challenges in growing a product from hundreds to millions of visitors per month making thousands of transactions a day.
You like working with streaming/reactive architectures and have experience/interest in setting up MongoDB based cloud infra from scratch. You generally prefer to use a minimal set of simple tools to a diverse range of complex ones.
We are looking to build a back-end cloud infrastructure (on Java/Scala with Google Cloud Platform preferably) which will be a fault-tolerant real-time stream processing system on the cloud - Our system will need to meet liveliness guarantees from a web/API application perspective (and not a big data/ETL perspective).
You like to work on a variety of projects - at this job, you’ll be developing a complex backend API infra, a reactive streaming architecture and a cloud-native, highly available API for our customers.
You have:
Experienced in any JVM based language.
Have some experience in NoSQL and architecting APIs
Strong verbal and written communication skills and the ability to work well cross-functionally.
We offer:
You to be a part of a small, but a super capable team.
The opportunity to work closely with founders to define, scope, estimate and plan various aspects of the product. Being one of the first hires at Swift, you will be involved in both high and low-level decision making. This means a lot of ownership, which we cultivate by having a flat structure.
Competitive salary and stock options from a high-growth company.
