Frontend Software Engineer
We are growing to become a true global nextgen tech company that enables a more sustainable future, by providing specialized cloud operations, software and consulting services to the energy sector.
Now we are looking for a Frontend Software Engineer for the team building Cenova, an enterprise data management platform for the energy sector that helps companies discover and manage petabytes of technical data. You'll be creating the web interface that lets data managers and geoscientists search through millions of files, visualize complex datasets, and make sense of their distributed data landscape.
What you'll do
You'll work in an agile setup with regular iterations and feature releases, where code reviews and knowledge sharing are part of our daily flow. Frontend development happens in close collaboration with UX and UI designers, with strong cross-functional interaction across backend, product, and stakeholders. We follow a component-driven approach with reusability in mind and encourage the thoughtful use of AI tools like GitHub Copilot and Claude. Pragmatic engineering - we ship iteratively and improve continuously.
Your work will focus on advanced search interfaces, interactive data visualizations, and high-performance dashboards that remain responsive even at significant scale, using tools such as VS Code, Vue DevTools, browser DevTools, Git, and Azure DevOps. As a senior engineer we will count on you to support and mentor junior colleagues and help shape the direction of how we work.
Interesting problems you'll tackle:
-
How do you render tables with millions of rows without freezing the browser?
-
How do you build visualizations that reveal patterns in massive datasets?
-
How do you create search interfaces that feel instant even with complex multi-faceted filtering?
-
How do you manage application state when dealing with real-time data updates across modules?
-
How do you optimize bundle sizes while keeping the DX smooth with hot module replacement?
Tech Stack
Core Technologies:
-
Vue.js 3 (Composition API, script setup)
-
TypeScript
-
Vite (fast dev server and build tool)
-
Pinia (state management)
-
Vue Router
UI & Visualization:
-
PrimeVue - comprehensive component library with extensive customization
-
PrimeFlex - utility-first CSS for rapid layout development
-
Chart.js - flexible charting for complex data visualizations
Development Tools:

Protocol Buffers - type-safe API contracts between frontend and backend
-
Husky & lint-staged - automated code quality checks on every commit
-
Azure DevOps - CI/CD and collaboration
What We're Looking For
We need someone who can architect scalable component systems and knows when to refactor versus ship. You should have:
-
You've shipped frontend applications users depend on and understand performance tradeoffs, and are comfortable driving technical decisions
-
Deep understanding of modern JavaScript frameworks - Vue, React, or Angular with strong grasp of reactivity and component lifecycle (Vue.js 3 experience is a big plus)
-
Expert-level TypeScript - you use advanced types to catch bugs and make code maintainable
-
Strong CSS skills with Flexbox, Grid, and responsive design
- Managed complex application state with Pinia, Vuex, Redux, or similar
-
Handled REST API integration elegantly - async data, errors, and loading states
-
Experience with Chart.js, D3.js, or data visualization libraries is valuable
-
Web performance optimization, accessibility, testing frameworks, or component library experience are all pluses
-
Data management or enterprise application experience is helpful but not required
