We use the latest web standards in HTML, CSS, JavaScript, and Ruby, and modern technologies and frameworks like Ruby on Rails, React, GraphQL and Cypress to develop large front-end websites and applications that are intuitive, scale globally and perform well on all devices.

You will be working along with UX designers, frontend developers, and product managers to build and launch new features for our websites. You'll work on large-scale websites and applications that are continuously changing. Our web development teams are mainly working with Ruby on Rails and ReactJS.

We are now looking for web developers with strong experience in Ruby, Ruby on Rails, and ReactJS, expertise in modern web-technologies and RESTful APIs, and that are independent and inventive, have a hunger to learn, share knowledge, and thrive in an energising environment that delivers great products and provides great developer experience.

Experience with integrating AI-powered APIs or tools into web applications is a strong plus, as we’re keen to adopt practical AI solutions across our platforms.

The role includes collaborating with experienced software engineers to iterate on the design and implementation of our products across multiple desktop, tablet and mobile browsers.

What you'll do as a Web Developer at BVGroup:

You will develop and code at all levels of various websites and API applications, writing software with focus on great user experience, scalability and performance. We want you to play a key role in the full development cycle and direction of product and feature sets, turning feature requests and technical requirements into a set of re-usable components using elegant code solutions.
Architect full-featured server-side applications using mainly Ruby on Rails, ReactJS, Redis, SQL, and other technologies.
Participate in the full development cycle and direction of product and feature sets, turning feature requests and technical requirements into a set of re-usable components using elegant code solutions.
Help us shape the internal software architecture and development, from requirements gathering, to design and implementation, to production deployment. Development, operations, testing and others all work together to ship outstanding code to production.

Experience and skills that you will need to be successful in this role:

3 years' minimum experience in web development.
Expert in MVC web technologies and REST APIs.
Strong experience with Ruby and Ruby on Rails; alternatively experience with any of scripting languages for web (PHP, Python, Elixir, NodeJs) and a willingness and capability to learn Ruby fast.
Strong competence with JavaScript – You will be very familiar with the JS landscape of technologies and have knowledge and experience in using it in tandem with server-side technologies to create fast, responsive, websites. Currently we use ReactJs on a daily basis.
Passionate about web development – you are familiar with all aspects of MVC web applications and as ease on the server side as on the client side, applying the most adequate pattern in the right situation.
Comfortable working across the stack and understanding how all the pieces fit together (front-end, middleware, network layer, etc.) and how they impact the performance of your application.
Experience with client and server-side performance optimisation and tuning.
You have interest in working in a very cross-functional team that touches on many of the core systems and user flows.
A solid engineer – you find something magical about solving problems with elegant but simple solutions. You have deep knowledge of OOP and design patterns and are a good problem solver with attention to detail and critical thinking skills.
A good communicator – you communicate enthusiastically, clearly and concisely with both technical and non-technical colleagues.
A keen learner – you are up-to-date and capable of keeping the pace with the latest trends and technologies in web development.
Bias towards action. You are hands on, passionate, persistent, creative and humble. You get things done.
Experience leveraging AI-powered tools or APIs (such as OpenAI, GitHub Copilot, local running LLMs, or similar) to aid in software development - generating code, automating test-case creation, detecting bugs, improving performance, or assisting with code reviews.

How we hire:

Our interviews are a two-way process, and we want you to have the time and opportunity to get to know us, as much as we are getting know you! Our interviews are conversational, and we want to get the best from you, so come at us with questions and be curious.

💬 Potential Interview Questions

What are the advantages of using Ruby on Rails for building scalable web applications?
Rails offers rapid development through convention over configuration, built-in ORM (ActiveRecord), and a robust ecosystem that promotes maintainable and scalable code.
How does React complement Ruby on Rails in a fullstack web application?
React handles dynamic and interactive UIs on the client side, while Rails manages server-side logic and data persistence, creating a clear separation of concerns.
How do you optimize the performance of a Ruby on Rails application?
Use caching strategies (e.g., fragment, page, and SQL caching), optimize database queries, reduce N+1 issues, and implement background jobs for non-blocking tasks.
Explain your experience using RESTful APIs in fullstack development.
Design RESTful endpoints following resource-based routing, use proper HTTP methods and status codes, and handle authentication and rate limiting for secure integration.
What are some key differences between MVC in Ruby on Rails and component-based architecture in React?
Rails follows traditional MVC with clear separation between model, view, and controller, while React organizes UI into reusable components with local state and side effects.
How do you integrate GraphQL into a Ruby on Rails and React stack?
Use gems like graphql-ruby for the Rails backend, define schemas and resolvers, and use Apollo Client or Relay in React for querying and managing application data.
Describe your approach to performance tuning on the client side in React.
Use memoization (e.g., React.memo, useMemo), lazy loading, code splitting, minimizing re-renders, and monitoring with tools like Lighthouse or Chrome DevTools.
What strategies do you use for fullstack testing in Rails and React applications?
Use RSpec for backend unit and integration tests, Cypress or Jest for frontend testing, and ensure end-to-end test coverage of user flows.
How have you used AI tools like GitHub Copilot or OpenAI in your development workflow?
Used AI to generate boilerplate code, refactor functions, create test cases, identify potential bugs, and accelerate prototyping through contextual code suggestions.
How do you ensure seamless communication and integration across frontend and backend in a fullstack environment?
Define clear API contracts, maintain shared documentation (e.g., Swagger, GraphQL schema), implement consistent error handling, and use version control for backward compatibility.
