PHP Backend Engineer (Symfony) (1 x Mid Level + 1 x Lead Level)
Building the Future of Loyalty!
Location: Bristol or London, UK or Europe-based with Remote working.
Are you passionate about crafting robust, scalable, and innovative backend systems? Do you believe that seamless data flow and powerful APIs are the bedrock of genuine customer loyalty? If you thrive on solving complex technical challenges and want to see your code directly impact how businesses connect with their customers, then you might be exactly who we're looking for!
At TRIFFT Loyalty, we're not just another tech startup – we're a sector disrupter on a mission to revolutionise how businesses build genuine, long-lasting customer loyalty. We're an innovative, fast-growing company, and our platform is changing the game by empowering mid-market businesses to create truly dynamic, personalised, and impactful loyalty programs without the usual technical headaches. Our backend is the engine that drives this transformation.
We believe that true loyalty extends beyond transactions. It's about emotional connection, and our platform, powered by our sophisticated backend, empowers brands to forge those unbreakable bonds.
We are seeking an experienced PHP Backend Engineer who is passionate about designing scalable systems, working with modern architectural patterns, and shaping the future of customer loyalty technology.
What you'll do as a TRIFFT Loyalty Backend Developer
* Develop and maintain high-performance applications and services supporting millions of transactions processing and rewarding loyalty mechanics — designed to handle high loads and scale globally.
* Build asynchronous integrations between systems (e.g., mobile apps, partner APIs, payment/pos providers, ecommerce platforms like Shopify and WooCommerce), focusing on efficiency and reliability.
* Design and implement services that follow Domain-Driven Design (DDD), Event Sourcing, CQRS, and event-driven architecture principles.
* Actively participate in architectural decision-making.
* Contribute to improving system scalability, resilience, and maintainability in a fast-growing environment.
* Languages & Frameworks: PHP 8.4 on RoadRunner, Symfony, Spiral, modern PHP ecosystem tools
* Databases: MySQL, PostgreSQL, Redis and non relational databases (Elastic, CosmosDB)
* Other tools: Docker, Git, CI/CD (GitHub Actions), betterstack, monitoring with modern observability tools
What you'll bring to the TRIFFT Loyalty team
* 4+ years of experience in backend development with PHP (preferably Symfony or Laravel)
* Strong understanding of modern architectural patterns (DDD, CQRS, Event Sourcing)
* Hands-on experience with Kubernetes and containerized deployments
* Solid experience designing and integrating APIs (REST or GraphQL)
* Experience with relational and non-relational databases
* Familiarity with CI/CD pipelines and automated testing
* Excellent problem-solving skills and a proactive mindset
* Excellent communication and teamwork skills, able to articulate technical concepts clearly.
* A proactive, resilient, and self-motivated individual with a desire to learn and grow.
* Bonus Points (Nice-to-haves):
* Experience with cloud platforms (AWS, Azure, GCP).
* Understanding of loyalty programs or e-commerce domains.
* Be part of something big: We're a fast-growing startup with a truly innovative product that's disrupting the market. Your code will have a direct and measurable impact.
* Real impact, real growth: This isn't a role where you'll be a cog in the machine. You'll have significant autonomy and the opportunity to shape our backend architecture and development practices.
* A collaborative and fun culture: We're a passionate team that supports one another, celebrates wins, and isn't afraid to laugh (even about database migrations!).
* Competitive compensation package, including uncapped commissions and ESOP equity.
* Opportunities for professional development and career advancement. We're growing, and we want you to grow with us!
If you're ready to build the powerful backend systems that transform customer loyalty, then we want to hear from you!
