Senior Ruby Developer

Software Development


At SQUAKE, we are on a mission to decarbonise the travel and logistics space, accounting for roughly 25% of the worldwide CO2. With us, companies get the support they need to become CO2 neutral. In a nutshell, SQUAKE supports clients by providing them with a state-of-the-art carbon API - built by developers for developers.

About the Role

As a senior developer, you are someone who can see projects through from beginning to end, coach others, and self-manage. We’re looking for an eager person who can bring our team to the next level with their technical knowledge, people skills, and real-world experience.

On the technical side, extensive experience building high-traffic websites using Ruby and Ruby on Rails is a hard requirement. Experience with DevOps(AWS services, Terraform) and Frontend(Vue.js, TailwindCSS) is a plus but not required.


  • Design and build the core infrastructure that powers SQUAKE’s products.
  • Write high-quality, maintainable code that is easy to understand and modify.
  • Collaborate (as well as in code pairing sessions) with other engineers and teams to design and implement new features.
  • Work with best practices, for example, canonical loglines, data-driven decision-making, testing that also covers performance, etc.


  • You have 5+ years of Ruby and Ruby on Rails experience
  • You’ve built complex apps in a Ruby on Rails + modern frontend stack before, with a codebase optimised for performance and scale
  • You’ve designed & shipped large applications with many components and data structures
  • You have a proven ability to design interfaces that stand the test of time, showing anticipation of future product changes
  • You have experience integrating complex third-party APIs
  • You can successfully refactor existing code and get rid of tech debt without regressions


  • Join the change makers, and be part of our world’s sustainable transformation.
  • Be part of a human sized, passionate, and fun crew where everyone’s voice counts
  • We enjoy growing our company as well as our team! We are dedicated to supporting your personal development path
  • Work from anywhere: the office, your home, the beach or wherever you feel your best self
  • A modern and cosy office at the heart of Berlin with free coffee and beverages
  • Team events and activities to enjoy together

If you think you can push projects through uncertainty and ambiguity, can take a joke, collaborate with others and can zoom out to see things from a birds-eye perspective then you are the right fit for our expanding team.


SQUAKE is an equal opportunity employer and proudly values diversity. We encourage candidates of all personal and professional backgrounds, identities, experiences and seniorities to apply.
