ABOUT RANKTRACKER
⠀
Ranktracker is a SaaS platform for SEO professionals, agencies and businesses.
⠀
Our tools cover rank tracking, keyword research, competitor analysis, backlinks, website auditing, SERP analysis and AI search visibility.
⠀
We are based in Poland and work remotely.
⠀
THE ROLE
⠀
You will be the only frontend developer working on the Ranktracker application.
⠀
You will work closely with our senior backend developer and take ownership of the frontend.
⠀
We do not usually provide detailed Figma designs or pixel-perfect mockups. Most work comes from GitHub tickets containing requirements, screenshots, examples and acceptance criteria.
⠀
You need to be able to take a ticket, understand the problem, make sensible UI/UX decisions and deliver the finished feature independently.
⠀
CLAUDE CODE
⠀
We use Claude Code as part of our development workflow and expect you to use it effectively.
⠀
However, we are not looking for a vibe coder.
⠀
You must be a strong developer who actually knows how to code and understands the codebase, architecture and code you are writing.
⠀
Claude Code should make you faster. It should not replace your technical knowledge.
⠀
You should be able to review generated code, spot bad implementations, debug problems yourself, refactor properly and make sensible architectural decisions.
⠀
If you cannot explain how your code works, it should not be shipped.
⠀
WHAT YOU WILL WORK ON
⠀
• Build new Ranktracker tools and features
• Improve existing parts of the application
• Build dashboards, tables, charts and filters
• Work with large amounts of SEO data
• Integrate GraphQL and REST APIs

• TypeScript
• Vite
• GraphQL + Apollo Client
• REST APIs
• Zustand
• Mantine UI v8
• React Router
• Nivo
• MapLibre GL
• i18next
• WebSockets / Rails ActionCable
• Playwright
• ESLint + Prettier
• Docker
⠀
We use Mantine UI, but we do not rely heavily on presets. We often build our own components so we have full control over the markup, behaviour and styling.
⠀
BACKEND STACK
⠀
• Ruby on Rails API
• PostgreSQL
• Redis
• Sidekiq
• RSpec
⠀
You do not need to be a backend developer, but you should be comfortable working with APIs and working closely with the backend developer.
⠀
REQUIRED SKILLS
⠀
• 5+ years of frontend development experience
• Strong React and TypeScript experience
• Strong HTML and CSS
• GraphQL and REST API experience
• Good understanding of frontend architecture
• Experience with state management
• Experience building SaaS or data-heavy applications
• Strong debugging and problem-solving skills
• Good UI/UX judgement
• Ability to work independently
• Ability to work from GitHub tickets without detailed designs
• Good Git/GitHub workflow
• Comfortable using Claude Code properly
• Strong attention to detail
⠀
GOOD TO HAVE
⠀
• Mantine
• Apollo Client
• Zustand
• Playwright
• Nivo or other charting libraries
• MapLibre or mapping experience
• WebSockets
• i18next
• Docker
• Experience as the main frontend developer on a SaaS product
⠀
WHAT WE ARE LOOKING FOR
⠀
We want someone who can take ownership of the frontend and genuinely knows what they are doing.
⠀
You should be proactive, able to make sensible decisions and comfortable working without constant supervision.
⠀
If something does not make sense, raise it.
⠀
If the UX can be improved, suggest it.
⠀
If Claude Code produces something poor, fix it rather than accepting it.
⠀
If a feature is not properly tested, it is not finished.
