Senior Full-Stack Engineer, Frontend-Focused
Software Engineering
Sofia, Bulgaria
Posted on Nov 3, 2026
The Impact You'll Make
Do you want to build software that does something good for the planet by saving energy and fighting food loss? We make it happen with our software for industrial refrigeration systems.
Our twin product, Alsense, provides similar functionality for supermarkets. You will work on its counterpart for industrial users.
What You’ll Be Doing
- Build React microfrontends for our IoT product (~75% of your time)
- Co-develop the APIs used by the UI together with the backend engineer on your team (~25% of your time)
- Use and contribute to our internal React-based design system
- Work with test automation, CI pipelines, and frequent deployments
- Build and iterate on the interface together with our UX designer
- Propose and implement improvements to our large frontend codebase, made up of multiple microfrontends
- Use AI-assisted practices to move faster without giving up engineering rigor
What We're Looking For
You're a strong UI engineer who's happy to build the endpoint your feature needs instead of waiting for someone else to do it. You own features end to end and help shape frontend architecture decisions.
- Solid frontend experience with React
- You've worked in a real, non-trivial TypeScript codebase
- You know React and Redux
- You have experience with microfrontends
- You have experience with integration and end-to-end tests
- You use feature flags to ship your work frequently
- Nice to have:
- Experience working with design systems
- Experience with tools like styled-components and SWC
- API development experience
- Preferably in Go, TypeScript, or Java (this is what we use)
- Willingness to learn about IoT, event-driven architecture, PostgreSQL, and message queues
- When we need to build something with a technology you don't know yet, your answer is "I want to learn it" (for example, data pipelines, Sparkplug B, or observability)
- Experience with structured AI-assisted engineering: automation beyond prompting
- Working proficiency in English (our team language)
What You'll Get from Us
Work in a small team where your decisions have a tangible impact. Learn about the refrigeration domain in the context of IoT products. Hybrid work setup based at our office in Sofia.
