About the role
Join us as a Senior Fullstack Engineer in our Belgrade office and help shape the next chapter of our CRM platform for real estate professionals in Switzerland. The platform plays a central role in supporting top real estate agencies - and we're now making strides to evolve into the future.
We’re looking for a strong, hands-on engineer with a bias for ownership, happy to take problems from idea to production and stick with them until they work reliably. You’re comfortable across the web stack and bring strong modern frontend skills, adding fast prototyping and frontend depth to a backend-leaning team so we can raise the bar on our UI and UX. You don’t have to be an expert in everything on day one - we care most about solid engineering fundamentals, strong ownership and the willingness to grow into the rest.
In this role, you'll balance system stability with long-term thinking. You’ll take ownership across the stack, challenge assumptions and work closely with others to continuously improve how we build, ship, and evolve our platform:
Lead frontend architecture and delivery - own key UI flows and components; keep accessibility and performance high; design clear data and state flows; prototype and iterate quickly (from product ideas to tech spikes) and turn them into robust, maintainable code in a large existing codebase.
Build and run the stack end to end - work hands-on with the team across UI, services, APIs, infrastructure, pipelines, deployment and operations; shape monitors and SLIs/SLOs; keep alerts clear and actionable; and take a leading role in incidents and follow-ups for your area.
Partner with Product and Design on UX and service contracts - co-lead discovery, make trade-offs explicit early, design APIs that keep the UI fast and simple, and ship in small, reviewable increments so we can learn and adjust quickly.
Bring strong product sense - connect engineering decisions to customer and business outcomes, measure impact, course-correct based on what we learn, and sequence work for value, feedback and risk reduction.
Build and operate on Cloud - apply solid architectural understanding of cloud-native systems, ideally on AWS; experience with GCP, Azure or Kubernetes and a willingness to get hands-on in our environment are very welcome.
Streamline delivery - improve CI/CD for web apps, remove friction on the path to production, and keep docs and runbooks current and usable so others can move quickly and safely in the codebase.
Mentor and coach - pair regularly, give thoughtful reviews, share knowledge through sessions, docs and demos, and provide timely, actionable feedback that helps teammates deepen and broaden their skills.
Our tech stack
Frontend: React (current) with TypeScript/JavaScript; testing with Jest, Puppeteer and Cypress. Vue experience is a strong plus, as we’re potentially moving toward Vue and value experience with migrations and prototypes.
Observability: Datadog (including RUM) and Kibana for logs/metrics/traces; clear, actionable alerting.
Backend & Infrastructure: Services in TypeScript/Node.js; PHP in legacy areas; containers and serverless; Infrastructure as Code (IaC).
CI/CD & Docs: GitHub Actions; Backstage for service catalog and documentation.
About you
6+ years building user-facing products with end-to-end ownership
Frontend-leaning full-stack engineer with strong UI/UX fundamentals
Comfortable working across services, data and cloud; AWS experience or fast ramp-up from GCP/Azure or Kubernetes
Happy to dive into unfamiliar parts of a larger codebase, prototype quickly and then harden solutions
Solid systems thinking: clear interfaces, sensible trade-offs, pragmatic modernisation of legacy code
Fluent in English and confident in an international environment
