Frontend Engineer

Posted Sep 18



Hey, we're Sparta Commodities!

We are a Swiss, VC-backed startup with a global reach. Our mission is to digitize the commodity trading market and become the leading platform for traders in all commodities verticals. We've already gained significant market traction and are financially backed by Venture Investors.

We have a fantastic opportunity available for a driven and passionate Frontend Engineer to join our growing Engineering team, based remotely in Spain. This is a great career opportunity for an experienced and delivery-focused Frontend Engineer to play a key role in the development and maintenance of various front-end systems, including an Excel plug in, for a leading and highly regarded business.

About The Team

Our naturally diverse teams are divided into verticals, with a mix of multidisciplinary members. Each team has at least 2 Backend Engineers, 2 Frontend Engineers, a Designer, a QA Engineer, a Product Owner, and a Team Manager. We work on bi-weekly sprints with quarterly goals. Each project is kicked off by a product request, from which we build a technical proposal that is refined within the team. Once the project has been greenlit one team member becomes its owner. An owner follows the project through development and deployment, making the other team members accountable for their responsibilities.

About The Tech

We have a modern React website, built with libraries such as Redux and SWR. Our Components are designed around Material UI and styled with SASS. We have plenty of financial data to graph in charts, for which we have extended chartjs. Our designers share Figma wireframes with beautiful adaptive designs. In 2023, we doubled our website's screen count, with intentions to sextuple it by late 2024. We've also ventured into TypeScript web technologies to develop Excel Add-Ins.

About You

We are looking for someone who has had ownership of projects from inception until after release, and who is familiar with observability, product metrics, and maintainability. They will be involved in the design of technical solutions as owner and implementor, on top of reviewing designs from other team members.

On your day-to-day, you will work within the team reviewing code and promoting initiatives to improve our code quality, maintainability, and development experience. As part of the development sprints, you will release new features and products using quality practices such as automated testing, QA validation, and monitorization.


  • Ownership and accountability for projects and their product metrics
  • Experience and prior work with React
  • Prior work on real-time systems such as WebSockets, stock tickers, or videogames
  • Experience and prior work with Redux
  • Experience with Jest, Mocha, or other common testing libs
  • High communication skills in a remote-first company with a diverse workforce

Bonus Points

  • NextJS or similar
  • Experience with cypress for e2e tests

Benefits and Perks

  • An opportunity to be part of a disruptive Scale-up that is challenging the status quo on commodity trading data and analytics
  • Competitive salary and benefits package
  • 100% remote working, we offer an excellent work-life balance!
  • Private healthcare
  • Attractive and hopefully life-changing company stock option plan
  • Yearly company-wide meet-ups (we’re off to Mallorca this year!)
  • Training and education budget, ensuring your continuous growth and development
