Quartr is a software company serving the world of finance. Every day, leading companies and financial institutions worldwide use our products to research faster and understand deeper.

For too long, markets have been obsessed with numbers. Everyone has access to the same quantitative data, while qualitative insights – the words, the signals, the nuance – have remained mostly in the shadows. We make those insights accessible, searchable, and actionable.

Our products are used daily by some of the most sophisticated teams in finance and tech, including major hedge funds and Magnificent 7 companies, and over a million finance professionals have downloaded our mobile app.

We're backed by some of the smartest minds in our industry and growing fast at a global scale, and we're still at the very beginning of what we expect to be a multi-decade journey.

As part of the Web App development team, you will collaborate closely with engineers, product managers, and designers. You'll also interact with customer relations, marketing, and sales. This is a truly end-to-end role: you'll design, build, and ship features across the stack, from backend services and APIs to sleek, responsive UIs. Your work will directly shape the user experience and help scale our rapidly growing platform. 


What you'll do

  • Take end-to-end ownership of features: design, implement, and deploy both backend and frontend parts

  • Contribute to the architecture and scalability of our backend services

  • Build responsive and performant UIs that users love

  • Collaborate closely with product and design to shape features from concept to release

  • Continuously improve our codebase, tools, and workflows


Who you are

  • Have solid experience in frontend and backend development (ideally with modern JavaScript/TypeScript frameworks)

  • Enjoy working on end-to-end feature development, and you write clean and maintainable code

  • Actively contribute to a friendly, collaborative work environment

  • Feel comfortable in a high-tempo environment where priorities can shift quickly

  • Are fluent in English (our company language), both written and spoken

  • Be self-driven, proactive, and take full ownership of your projects

  • Communicate clearly and effectively, thriving in a high-paced, collaborative environment

  • An interest in finance and the financial markets is a big plus

  • Adapt quickly to new technologies and frameworks, with curiosity to explore tools like Bun and Elysia as we evolve our stack


What we offer 

  • Do your life's work: The world's leading finance professionals use Quartr daily. We do fewer things better and hold a very high bar for quality.

  • Join the foundational team: We're still at the very beginning of a multi-decade journey. You'll have a big influence on product, culture, and how we win.

  • Real ownership: We believe in shared success. Every team member gets equity exposure, so we all benefit from the value we create.

  • Meritocracy over hierarchy: You'll join a culture where the best idea wins. We value clear thinking, leave ego at the door, and obsess over the details.

  • Office culture with flexibility: Join us in one of our offices. We value being together, while also offering the flexibility to work from home when needed.

  • Compensation & well-being: We offer competitive salaries, benefits, and a generous wellness allowance to support your physical and mental health.

We include occupational pension for all employees in Sweden.
