About the Role

We’re looking for a Senior PHP Engineer to join our Mexico expansion team, helping to drive us towards the launch of a new mobile finance product that aims to further our international growth. We’re looking for someone excited by the idea of joining a small cross-functional product team with a startup mindset, operating within one of Europe’s most successful, profitable fintechs, to support the initial build of a new product offering for this new market.

Who you are

  • Our ideal candidate is an experienced and resourceful engineer, comfortable building relationships with other established product teams to understand where we can use existing learnings to influence decisions and align on approaches, collaborating with frontend engineers to guide and agree API behaviours and expectations through documented contracts, and working closely with product stakeholders to agree on MVP requirements
  • Strong, business oriented, engineer with modern PHP development experience (PHP 8.0+ is a must). You're fluent in the latest PHP features and best practices
  • A solid grasp of a modern PHP framework like Symfony or Laravel
  • Experience with Domain Driven Design, Message-Driven Systems, and Event Sourcing is a significant plus
  • Familiarity with microservices architecture and working on financial systems is a bonus
  • Excellent automated testing skills (unit, integration, functional) - you believe in quality code
  • You have experimented with AI tooling to accelerate your own, and others, productivity, and can discuss the positives and negatives of different approaches and tools
  • A genuine desire to learn, collaborate, and contribute your ideas within a highly collaborative team
  • High degree of ownership and autonomy
  • Experience in a cross-functional environment is a plus
  • Written or spoken Spanish at intermediate (B2) level or above would make you stand out, but is not essential for this role

What the job involves

Backend: PHP 8, Symfony, AWS, PostgreSQL, RabbitMQ, Docker, Kubernetes

CI/CD: Datadog, GitHub Actions and ArgoCD

Testing & Monitoring: Behat, PHPUnit for robust automated testing, Datadog for monitoring

Application process

  • A short video call with one of our team members to learn more about each other, and answer any initial questions you have about the role
  • A short practical coding exercise to complete in your own time
  • A technical session with your peers where you’ll discuss your solution to the exercise, talk through some problems and scenarios, and dig deeper into your technical experience
  • An interview with an Engineering Manager to explore your motivations and goals, assess how you could play a part in your team’s success, and better understand how we could help you thrive in your role

Company Benefits

  • Best-in-class compensation, including equity
  • Comprehensive private health insurance (including dental, optometry and general wellbeing)
  • Multiple opportunities to socialise with your team and the wider company
  • Equipment provided for you to do your best work!
