At Factorial we don´t evaluate you by the years of experience you have, we evaluate your knowledge and skills. How? We have a Career Path with a rubric framework where we define what is expected for each experience level and skill. This framework allows you to know at which level you´re right now and what you need to keep growing. As we love transparency, our Career Path includes the salaries for each level and we share it during the first interview to make sure we´re aligned.

For this mid-level position, the annual gross salary is 86,250€. This includes a base salary of 75,000€ and a variable pay of up to 11,250€ annually (paid quarterly), depending on the company´s goals and quality metrics.

The main application uses Ruby on Rails for the backend and React for the frontend. As a Staff Engineer we expect that you will be able to implement features across all of the stack, and this sometimes includes parts of the application (a middleware, or the local development setup). If you would not be comfortable with these tasks, you may still apply, and we´ll evaluate you against the Senior+1 level, which means you´re fully focused on the infrastructure only.

Your daily life with us

You will be a product-centric engineer (not a ticket-handling machine), taking ownership of mid and large-size initiatives, in parallel to routine maintenance or incident resolution work.

You will review code, and get feedback on your own code.

You will learn from the entire team, both on technical topics (performance, architecture...) and core skills, in an environment driven by engineering quality.

You will share your knowledge, through the RFCs you write, pairing sessions, our mentoring programme or the occasional appearance in the monthly Tech All Hands.

Benefits

We care about people and offer many benefits for employees:

- High growth, multicultural, and friendly environment
- Continuous training and learning based on your needs
- Alan private health insurance
- Healthy life with Gympass (Gyms, pools, outdoor classes)
- Save expenses with Cobee
- Language classes with Preply
- Get the most out of your salary with Payflow

And when at the office...

- Breakfast in the office and organic fruit
- Nora and Apetit discounts
- Pet Friendly
