Backend Software Engineer

Our Partner is building a solution connecting open banking APIs with open blockchains to  radically improve usability of decentralized apps. The start-up is ranked among top 10 Polish start-ups according to Crunchbase and secured funding from top US and UK investors. You will be working together with senior back-end developer ex-Googler, built his own start-up before, FinTech and Ethreum veteran. 

 

We are after someone who:

has experience in building intricate backend systems 
demonstrates „getting things done” attitude
is no stranger to solid principles of software design 
is excited by the possibilities of working on the intersection of FinTech and blockchain technologies 
and has the determination to tackle challenging problems on a daily basis 


You'd be ideal if on top of that you:

have experience in managing infrastructure on Google Cloud Platform (Kubernetes is a plus!)


Day in a life

Your day to day work will consist of several backend tasks:

cooperating with others on our core settlement engine integrating open banking APIs with open ledgers
developing internal tools

The biggest challenge you will be dealing with is stable management of multiple data sources (open banking APIs and blockchain)


What will you get?

junior : 8-12k PLN net on invoice (or equivalent)
mid/senior: 13-20k PLN net on invoice (or equivalent)
0.3% - 1% equity
Relocation support if needed
Paid holidays and sick leave when you need it.
Refunded sports and health packages.
Team lunches, snacks and drinks 
Flexible hours but make sure you make it to 10AM stand-up 

Requirements

The codebase is written almost entirely in TypeScript, so thumbs up if you're familiar with it (and if not, get familiar, it's brilliant). JavaScript is also fine.  
The company is recruiting for junior, mid and senior positions. 



Backend stack:

TypeScript
  • nestJS (Node.js framework)
  • PostgreSQL
  • RabbitMQ

We need you to be familiar with at least some of these technologies, but language is just a language, what's more important is the way you think about creating stuff. Definitely show off your GitHub profile (+1 for blockchain-related contributions) and brag about developing reliable, high-quality software.


Here’s the rest of the stack if you’re curious:

Frontend:

TypeScript
  • react
  • redux + redux-saga / MobX
  • jest.js

DevOps:

Google Cloud Engine
  • Docker
  • CircleCI
  • and others

Blockchain (they are working solely on Ethereum at the moment):

  • Solidity
  • web3.js
  • ethers.js


The backend and blockchain development team comprises of MIM UW and PW graduates, so if you’re one as well, that can be a plus ;)

Start-up experience, especially with rapid prototyping, is also a big +1.
