    About Volt

    Volt is revolutionising how people pay online, globally. Our technology frees consumers from cards by letting them ‘Pay by Bank’. It’s effortless. It’s lightning fast. It’s the future. For businesses everywhere, it’s transformative. 

    We’re already trusted by leading brands around the world, but the real-time revolution is only just beginning. Having raised $83.5m, we’re accelerating our mission of delivering real-time payments, everywhere. And that’s where you come in.

    We need world-class talent to create a world where consumers pay, and businesses get paid, instantly. With headquarters in London and offices in Berlin, Kraków and Warsaw – and an all-star team already in place – we’re sure you’ll fit right in. 

    About the role

    As a PHP Software Engineer you will work across the development lifecycle, building leading edge disruptive financial technology solutions. The role presents an exciting opportunity to join an Agile team of talented software engineers, working to drive best practice across all projects to deliver our vision of world class customer centricity.

    About our tech choices

    We are designing our solutions with Domain-Driven Design principles in mind. That led us among other things to use the hexagonal architecture as our base pattern for the business layers of our apps. The systems as a whole are built with the best practices of microservices architecture, including CQRS, language-agnostic protocols, containerization, etc.

    Above all, we are keeping the balance between novelty and delivering a business value since that is the ultimate goal of our tech stack.

    What the role involves

    • Develop software applications using your extensive knowledge of PHP 8.1/8.2, Symfony 6.2, Doctrine ORM and associated technologies,
    • Participate in software design meetings and analyse user needs to determine technical requirements,
    • Write efficient, reusable and maintainable code, whilst adhering to coding standards,
    • Apply object-oriented programming, relational database technologies and modern frameworks for optimum solution per specification,
    • Test and maintain software products to ensure strong functionality and optimisation,
    • Recommend improvements to existing software programs as necessary,
    • Manage time appropriately and clearly communicate changes in effort or scope,
    • Contribute to documentation where required,
    • Maintain a high awareness of industry issues and trends.

    About you:

    • You have 3+ years of experience in developing web applications using PHP,
    • You have at least 2 years of experience with PHP based frameworks such as Symfony or Laminas,
    • You have at least 2 years of experience with ORM such as Doctrine or other (Eloquent)
    • You will be able to demonstrate experience working with SQL,
    • Knowledge of object-oriented programming (OOP), programming principles (Clean Code) and design patterns,
    • You have experience in developing and working with microservices,
    • You have experience in API development (testing, documenting, optimising and monitoring),
    • You have experience with queue services (AWS SQS, RabbitMQ),
    • You have been working in an Agile and CI/CD environment,
    • You possess strong communication skills, ability to explain your decisions to the team in written and spoken English,
    • Prior experience with Fintech products is more than welcome.

    What happens next?

    • Selected candidates will be invited for an initial interview with our People & Culture representative. The video meeting will take about 30 minutes,
    • We may ask you to prepare a task which will help us check your technical skills,
    • Then it’s time for a technical interview! The meeting will be conducted by two Technical Recruiters from PHP area and will last 1,5 hours,
    • Our SVP of Technology would also like to chat with you :) You can expect the meeting to last approximately 45 minutes,
    • If successful, you will be given a job offer proposal.


    • We champion ‘extreme ownership’ – being not just the owner of your own tasks, but a key member of a team united by, and accountable for, common goals,
    • During the week we mostly work remotely but for those who prefer to be in the office we arranged coworking spaces in Warsaw (Business Link Astoria) and Cracow (Loftmill),
    • Every Thursday, our employees meet and enjoy working together at the Puro Hotel in Cracow and Warsaw. There is always an opportunity to eat lunch together and grab some drinks after hours,
    • Every occasion is a good reason for celebration; we organise Christmas parties and company retreats,
    • We care about our employees’ health, so you will be provided with Multisport card and medical insurance by Luxmed,
    • We offer paid holidays (pssst...we will give you one day off extra for your birthday),
    • In addition, once every two months on Friday we close down all comms at Volt - a digital detox. The whole business is officially ordered to take the day off!
    • If you want to work in a company with a great, start-up atmosphere, you don’t have to look further :)

    At Volt, diversity and inclusion are integral to our culture.

    We believe in hiring for cultural add, embracing difference and fostering a safe space where everyone can bring their authentic selves. Our mission is to transform the payments industry and this is only possible through the power of our diverse and talented team.
