Your opportunity

Creating the technology foundation for a next generation smart assistant. In a team with a unique culture.

The Challenge

We are dealing with a highly dysfunctional market that takes advantage of customers. A market that bets on you being too lazy to track your subscriptions: Internet broadband, mobile phone, electricity, and others. The result: On average, you get overcharged by 900€ a year in Berlin.

Now imagine

A smart & honest assistant that optimizes all of your subscriptions automatically, without any effort for you. By identifying the best offers based on a constantly evolving recommendation algorithm. Continuously monitoring your contract status by tapping into hundreds of data sources and aggregating the information in a centralized dashboard. A smart assistant that behaves like a good friend does and pro-actively optimizes your subscriptions based on an elaborate rule-set.

Your role

As an experienced RoR developer, you are the beating heart of SwitchUp. You define processes in the backend that build blood vessels to fuel our drive. You directly impact our company’s rapid growth, delivering efficiency through automatization, and make first-hand decisions alongside your passionate teammates.

  • You will migrate our monolith  to microservices and make sure that we design our architecture in a smart way. You will drill into various ideas, debate on their implementations, create a smooth transition process, troubleshoot proactively. You are our Rome – all roads lead to you.
  • You will bring your Ruby skills, carefully nurtured for more than 5 years, on board. Being a self-starter and an inquisitive mind, you are willing to dive into new technology concepts, such as event sourcing. You’re not limited by a tech stack but make an asset out of every tool.
  • As you grow with us, you will make business decisions based on your expertise and help us reshape our customers’ interaction with the market. While you see a bigger picture with its gaps, loopholes, and potential failures, your ability to offer sustainable solutions turns you on.

What you bring

Ruby on Rails: 5+ years

Tech stack: Eventide, AWS, PostgreSQL, Redis, RSpec

Our team culture

Our philosophy is being built around a tricky question: Can we treat our customers and colleagues as good friends? We say ‘yes!’ and we are passionately experimenting with innovative approaches to anchor this rule.

We place a big emphasis on our team culture, which is different from most startups:

  • Fairness as a business model: As a "Tarifaufpasser" (Tariff Guard), we are reshaping the market by aligning it in favor of consumers and the environment. Our greatest success, besides the Stiftung Warentest award, is that our customers share our philosophy and genuinely like us.
  • Self-organisation & New Work: We believe in awareness and responsibility as opposed to hierarchies and formal schedules. In our roles concept, you try yourself in different contexts, reinvent and redefine yourself. This is your learning accelerator
  • Openness & Appreciation: We value every one of us and holistically support each other. Instead of hiding our mistakes and weaknesses, we deal with them openly and grow as human beings.
  • Learning: We constantly experiment with smarter ways of working.
  • Inspiration: We draw inspiration from partners such as the HPI School of Design with which we collaborated as project partner.

These are just a few tidbits about how we work. While our team has started other successful companies before ( is one of them), we believe that we still have a lot to learn. Hence, we are seeking a passionate colleague that not only has the talent to push forward our development effort, but also makes a profound impact on how we evolve as an organization.
