We are looking for an exceptional individual to join ExoMatter as a fullstack developer, working with Javascript and Ruby on Rails. In this role, you will be working directly on systems that power our Materials R&D platform.

Become part of a young deep tech and software startup based in Munich and revolutionize materials development with us. ExoMatter is a spin-off of the German Aerospace Center (DLR) and part of the UnternehmerTUM family of startups. We have a first product on the market with paying customers like Airbus and BSH and a strong upward trajectory.

Why are we doing this?

Our mission is to challenge the status quo of materials development to reduce the worldwide ecological footprint and increase the innovation speed.

We need you to succeed!

Do you think along these lines?

1. If you are equally convinced that only with more efficient materials, can we tackle the climate crisis
2. You are a maker and want to turn visions into reality. See your impact directly!

You love working in a dynamic team: trusting, exchanging feedback, and taking responsibility is most crucial.

As a fullstack developer, you will be adding new features to our customer-facing materials screening and computation platform. You will work in our small but growing development team, alongside our Python developers and our our team of materials scientists.

Knowledge about Materials Science is not required

• You will build new interfaces, implement new application functionality, and maintain the existing codebase
• You will develop with "vanilla" Javascript (no frameworks), CSS (based on Bootstrap), HTML, and Ruby; working directly in our Ruby on Rails codebase
• You will work on intergrations between our Ruby on Rails application and our Python computation backend, including scaling our queing and pooling systems

• You hold a degree in Computer Science or a related field
• You have 2+ years commercial experience working with both Ruby on Rails, and with Javascript (ideally without frameworks)
• You have strong experience in testing (specifically with RSpec)
• Ability to work autonomously and self-manage are very important
• Fluent in spoken and written English, German skills are a plus
• You live in Munich or want to move to Munich within 3-4 months and are then willing to work ca. 50% of your time on-site

Not required, but a plus:

• Experience working with Sidekiq, and/or other job management systems
• Experience in UI/UX design/implementation
• Experience with Python
• Experience working in a startup environment

• Competitive package of salary, (virtual) stock options, and benefits
• Attractive company culture in an early-stage startup
• Public transportation ticket for Munich and entire Germany (Deutschlandticket, 50 EUR per month covered by ExoMatter)
• Flexible work hours with strong focus on work-life balance far beyond industry standard
• Free choice between latest ThinkPads or MacBooks for personal and private use
• Full time position, part-time work possible upon agreement
• Hybrid work with flexible arrangement between on-site work in new Munich office and remote work

Start date: 1 May 2025.
