CompStak envisions a commercial real estate industry in which accurate and transparent data leads to better, faster deals for everyone. We gather critical information that is hard to access, then make it instantly and seamlessly available to our platform members.

Location: Belgrade, Hybrid (Currently, we are three days per week in the office, subject to change)

Our Exchange & Enterprise applications are where our customers live every day: searching properties, analyzing markets, and making real decisions off our data. As a Senior Frontend Engineer, you’ll be one of the primary owners of these apps. You’ll shape how thousands of users experience our product – from performance and usability to the workflows they rely on to do their jobs.

You’ll join a small, senior frontend team responsible for the main consumer-facing apps.

Design and ship end‑to‑end features: complex search flows, data‑rich dashboards, property and portfolio views, saved searches, exports, and more

Work directly in our React 18 + TypeScript codebase, making architectural decisions that impact how we build features for years

Dive into real product problems: how to surface dense information clearly, how to keep heavy pages fast, and how to make advanced tools feel simple

Collaborate closely with design and product on UX, and with backend teams on clean API contracts

Improve our foundations: testing strategy, patterns for state management, performance, and code quality

Guide other engineers, effectively participate in code reviews, and help define and follow our frontend standards

Core: React 18, TypeScript, Yarn

State & data: @tanstack/react-query, remains of Redux and a set of domain‑specific providers

UI & styling: styled-components, radix-ui and our internal ui-kit

Maps & visualization: rich mapping experiences using Google Maps and Mapbox, plus analytics views and charts

Tooling & quality: Vite, Jest, ESLint (React, hooks, JSX a11y, custom rules), Prettier

You have 5+ years of professional software development experience, including several years building complex React applications

You have 2+ years of hands-on experience working with TypeScript and feel very comfortable using it in production systems

You’ve seen what works (and what doesn’t) in larger codebases and care about code structure, boundaries, and long-term maintainability

You’re fluent in modern state management and data fetching patterns (React Query, SWR, etc.)

You naturally bring quality and ownership: you think about modularity, reusability, peer reviews, performance, and testing as part of “done”

You communicate clearly, enjoy collaborating with product/design, and like to give and receive feedback from other engineers

Working with maps/geo UIs (Google Maps, Mapbox)

Experience with or desire to use modern AI-assisted development tools (e.g., Cursor, AI pair-programming / code review tools) to move faster while maintaining code quality

Tuning performance in large React apps: bundle size, rendering performance, and real‑user performance metrics

25 days off per year: 21 days of vacation, plus an additional day for Slava, non-working Serbian holidays, in accordance with the Law, plus 3 days of 100% paid sick leave

You are covered with private health insurance, a package that will cover all your needs

We cover maternity and pregnancy leave with 100% of your earnings

Employee stock options

FitPass platform - because we care for your wellbeing as well

Quarterly activity and events budgets for each team and yearly company-wide team-building trip

Numerous perks in the office (Sweet Wednesday, Thursday office lunch, Movie nights…)
