Job description

Our only focus: Build and provide the best service for companies to handle payroll without outside help and very quickly.

How much time it takes to:
Add a company? 60 seconds
Add an employee? 30 seconds
Generate an employee's payslip? 10 seconds

We built a set of tools the past months to let our payroll team work on the business rules on their own, even making the functional tests in an automated way.
It includes:

  • a language with its LLVM parser (using Jison) used to create all the webapp forms
  • a runner that automagically build these forms for the users
  • a contextual analyser providing the data requirements to the runner

Because of a these tools, you won't deal with the business side ever and you'll just focus on what happen behind the scene. You'll be happy to play with the 500K operations required to generate a payslip and make them complete in < 0.5 second :)

Your main tasks:

  • Improve the global response time of our apis
  • Improve the security of our critical data
  • Improve the apps monitoring and build an efficient alerting system
  • Improve our current infrastructure and optimise the computing time

We use to ship a little something everyday to offer our customers a product continuously improved with some good surprises.

Our current stack:
Front-end - angular, react/redux
Dev build - webpack & babel
Back-end - nodejs (loopback), redis (mainly cache), elastic (indexation & aggregation)
Storage - mongodb (mongo cloud), aws S3
Workers - agenda + agendash, aws Lambda
CI & deploy -, docker cloud
Logs & metrics -, bugsnag

Preferred experience

We're looking for someone that will make our computes crazy fast, the thing that will make our payslip generations instantaneous. You know that milliseconds matter right?

We are 3 in the tech team right now, waiting for new geniuses to join us.
Hoping you already smile by reading these lines, we wait for you to say hi !
